PART 73—RADIO BROADCAST SERVICES
§ 73.625   TV antenna system.
(a)-(b) [Reserved]
(c) Antenna system. (1) The antenna system shall be designed so that the effective radiated power at any angle above the horizontal shall be as low as the state of the art permits, and in the same vertical plane may not exceed the effective radiated power in either the horizontal direction or below the horizontal, whichever is greater.
(2) An antenna designed or altered to produce a noncircular radiation pattern in the horizontal plane is considered to be a directional antenna. Antennas purposely installed in such a manner as to result in the mechanical beam tilting of the major vertical radiation lobe are included in this category.
(3) Applications proposing the use of directional antenna systems must be accompanied by the following:
(i) Complete description of the proposed antenna system, including the manufacturer and model number of the proposed directional antenna.
(ii) Relative field azimuth plane pattern (patterns for both horizontal and vertical polarization should be included if elliptical or circular polarization is used consistent with paragraph (d) of this section) of the proposed directional antenna. A value of 1.0 should be used for the maximum radiation in the horizontal polarization. The plot of the pattern should be oriented so that 0 degrees corresponds to true North. Where mechanical beam tilt is intended, the amount of tilt in degrees of the antenna vertical axis and the orientation of the downward tilt with respect to true North must be specified, and a tabulation of the elevation pattern included consistent with paragraph (c)(3)(vii) of this section. A horizontal plane pattern reflecting the use of mechanical beam tilt may be requested if required to facilitate international coordination.
(iii) A tabulation of the relative field pattern required in paragraph (c)(3)(ii) of this section. The tabulation should use the same zero degree reference as the plotted pattern, and be tabulated at least every 10 degrees. In addition, tabulated values of all maxima and minima, with their corresponding azimuths, should be submitted.
(iv) Horizontal and vertical plane radiation patterns showing the effective radiated power, in dBk, for each direction. Sufficient vertical plane patterns must be included to indicate clearly the radiation characteristics of the antenna above and below the horizontal plane. In cases where the angles at which the maximum vertical radiation varies with azimuth, a separate vertical radiation pattern must be provided for each pertinent radial direction.
(v) All azimuth plane patterns must be plotted in a PDF attachment to the application in a size sufficient to be easily viewed.
(vi) The horizontal and vertical plane patterns that are required are the patterns for the complete directional antenna system. In the case of a composite antenna composed of two or more individual antennas, this means that the patterns for the composite antenna, not the patterns for each of the individual antennas, must be submitted.
(vii) If an elevation pattern is submitted in the application form, similar tabulations and PDF attachments shall be provided for the elevation pattern.
(viii) If a matrix pattern is submitted in the application form, similar tabulations shall be provided as necessary in the form of a spreadsheet to accurately represent the pattern.
(4) Where simultaneous use of antennas or antenna structures is proposed, the following provisions shall apply:
(i) In cases where it is proposed to use a tower of an AM broadcast station as a supporting structure for a TV broadcast antenna, an appropriate application for changes in the radiating system of the AM broadcast station must be filed by the licensee thereof. A formal application (FCC Form 301, or FCC Form 340 for a noncommercial educational station) will be required if the proposal involves substantial change in the physical height or radiation characteristics of the AM broadcast antennas; otherwise an informal application will be acceptable. (In case of doubt, an informal application (letter) together with complete engineering data should be submitted.) An application may be required for other classes of stations when the tower is to be used in connection with a TV station.
(ii) When the proposed TV antenna is to be mounted on a tower in the vicinity of an AM station directional antenna system and it appears that the operation of the directional antenna system may be affected, an engineering study must be filed with the TV application concerning the effect of the TV antenna on the AM directional radiation pattern. Field measurements of the AM stations may be required prior to and following construction of the TV station antenna, and readjustments made as necessary.
(iii) In any case, where the TV licensee or permittee proposes to mount its antenna on or near an AM tower, as defined in § 1.30002, the TV licensee or permittee must comply with § 1.30002 or § 1.30003, as applicable.
(5) Applications proposing the use of electrical beam tilt must be accompanied by the following:
(i) Complete description of the proposed antenna system, including the manufacturer and model number. Vertical plane radiation patterns conforming with paragraphs (c)(3)(iv), (c)(3)(v) and (c)(3)(vi) of this section.
(ii) For at least 36 evenly spaced radials, including 0 degrees corresponding to true North, a determination of the depression angle between the transmitting antenna center of radiation and the radio horizon using the formula in paragraph (b)(2) of this section.
(iii) For each such radial direction, the ERP at the depression angle, taking into account the effect of the electrical beam tilt, mechanical beam tilt, if used, and directional antenna pattern if a directional antenna is specified.
(iv) The maximum ERP toward the radio horizon determined by this process must be clearly indicated. In addition, a tabulation of the relative fields representing the effective radiation pattern toward the radio horizon in the 36 radial directions must be submitted. A value of 1.0 should be used for the maximum radiation.
(d) It shall be standard to employ horizontal polarization. However, circular or elliptical polarization may be employed if desired, in which case clockwise (right hand) rotation, as defined in the IEEE Standard Definition 42A65-3E2, and transmission of the horizontal and vertical components in time and space quadrature shall be used. For either omnidirectional or directional antennas the licensed effective radiated power of the vertically polarized component may not exceed the licensed effective radiated power of the horizontally polarized component. For directional antennas, the maximum effective radiated power of the vertically polarized component shall not exceed the maximum effective radiated power of the horizontally polarized component in any specified horizontal or vertical direction.
§ 73.626   TV distributed transmission systems.
(a) Distributed transmission systems. A TV station may be authorized to operate multiple synchronized transmitters on its assigned channel to provide service consistent with the requirements of this section. Such operation is called a distributed transmission system (DTS). Except as expressly provided in this section, TV stations operating a DTS facility must comply with all rules applicable to TV single-transmitter stations.
(b) Authorized service area. For purposes of compliance with this section, a station's “authorized service area” is defined as the area within its predicted noise-limited service contour determined using the facilities authorized for the station in a license or construction permit for non-DTS, single-transmitter-location operation (its “authorized facility”).
(c) Table of Distances. The following Table of Distances describes (by channel and zone) a station's maximum service area that can be obtained in applying for a DTS authorization and the maximum interference area that can be created by its facilities.
Table 1 to Paragraph ( c )
(1) TV station zones are defined in § 73.609.
(2) DTS reference point. A station's DTS reference point is established in the FCC Order that created or made final modifications to the Table of TV Allotments, § 73.622(j), and the corresponding facilities for the station's channel assignment as set forth in that FCC Order.
(d) Determining DTS coverage. The coverage for each DTS transmitter is determined based on the F(50,90) field strength given in the Table of Distances (in paragraph (c) of this section), calculated in accordance with § 73.619(b). The combined coverage of a DTS station is the logical union of the coverage of all DTS transmitters.
(e) DTS protection from interference. A DTS station must be protected from interference in accordance with the criteria specified in § 73.620. To determine compliance with the interference protection requirements of § 73.620, the population served by a DTS station shall be the population within the station's combined coverage contour, excluding the population in areas that are outside both the TV station's authorized service area and the Table of Distances area (in paragraph (c) of this section). Only population that is predicted to receive service by the method described in § 73.619(c)(2) from at least one individual DTS transmitter will be considered.
(f) Applications for DTS. An application proposing use of a DTS will not be accepted for filing unless it meets all of the following conditions:
(1) The combined coverage from all of the DTS transmitters covers all of the applicant's authorized service area;
(2) Each DTS transmitter's coverage is contained within either the TV station's Table of Distances area (pursuant to paragraph (c) of this section) or its authorized service area, except where such extension of coverage meets the following criteria:
(i) In no event shall the F(50,50) service contour of any DTS transmitter extend beyond that of its authorized facility and its Table of Distances F(50,50) area; and
(ii) In no event shall the F(50,10) node-interfering contour of any DTS transmitter, aside from one located at the site of its authorized facility, extend beyond the F(50,10) reference-interfering contour of its authorized facility and its Table of Distances F(50,10) reference area; and
(iii) In no event shall the F(50,10) reference-interfering contour of a facility located at the site of its authorized facility extend beyond the F(50,10) reference-interfering contour of its authorized facility;
(3) Each DTS transmitter's coverage is contiguous with at least one other DTS transmitter's coverage;
(4) The coverage from one or more DTS transmitter(s) is shown to provide principal community coverage as required in § 73.618;
(5) The “combined field strength” of all the DTS transmitters in a network does not cause interference to another station in excess of the criteria specified in § 73.620, where the combined field strength level is determined by a “root-sum-square” calculation, in which the combined field strength level at a given location is equal to the square root of the sum of the squared field strengths from each transmitter in the DTS network at that location.
(6) Each DTS transmitter must be located within either the TV station's Table of Distances area or its authorized service area.
(g) All transmitters operating under a single DTS license must follow the same digital broadcast television transmission standard.
§ 73.658   Affiliation agreements and network program practices; territorial exclusivity in non-network program arrangements.
(a) Exclusive affiliation of station. No license shall be granted to a television broadcast station having any contract, arrangement, or understanding, express or implied, with a network organization under which the station is prevented or hindered from, or penalized for, broadcasting the programs of any other network organization. (The term “network organization” as used in this section includes national and regional network organizations. See ch. VII, J, of Report on Chain Broadcasting.)
(b) Territorial exclusively. No license shall be granted to a television broadcast station having any contract, arrangement, or understanding, express or implied, with a network organization which prevents or hinders another broadcast station located in the same community from broadcasting the network's programs not taken by the former station, or which prevents or hinders another broadcast station located in a different community from broadcasting any program of the network organization. This section shall not be construed to prohibit any contract, arrangement, or understanding between a station and a network organization pursuant to which the station is granted the first call in its community upon the programs of the network organization. As employed in this paragraph, the term “community” is defined as the community specified in the instrument of authorization as the location of the station.
(c) [Reserved]
(d) Station commitment of broadcast time. No license shall be granted to a television broadcast station having any contract, arrangement, or understanding, express or implied, with any network organization, which provides for optioning of the station's time to the network organization, or which has the same restraining effect as time optioning. As used in this section, time optioning is any contract, arrangement, or understanding, express or implied, between a station and a network organization which prevents or hinders the station from scheduling programs before the network agrees to utilize the time during which such programs are scheduled, or which requires the station to clear time already scheduled when the network organization seeks to utilize the time.
(e) Right to reject programs. No license shall be granted to a television broadcast station having any contract, arrangement, or understanding, express or implied, with a network organization which, with respect to programs offered or already contracted for pursuant to an affiliation contract, prevents or hinders the station from:
(1) Rejecting or refusing network programs which the station reasonably believes to be unsatisfactory or unsuitable or contrary to the public interest, or
(2) Substituting a program which, in the station's opinion, is of greater local or national importance.
(f) [Reserved]
(g) Dual network operation. A television broadcast station may affiliate with a person or entity that maintains two or more networks of television broadcast stations unless such dual or multiple networks are composed of two or more persons or entities that, on February 8, 1996, were “networks” as defined in § 73.3613(a)(1) of the Commission's regulations (that is, ABC, CBS, Fox, and NBC).
(h) Control by networks of station rates. No license shall be granted to a television broadcast station having any contract, arrangement, or understanding, express or implied, with a network organization under which the station is prevented or hindered from, or penalized for, fixing or altering its rates for the sale of broadcast time for other than the network's programs.
(i) No license shall be granted to a television broadcast station which is represented for the sale of non-network time by a network organization or by an organization directly or indirectly controlled by or under common control with a network organization, if the station has any contract, arrangement or understanding, express or implied, which provides for the affiliation of the station with such network organization: Provided, however, That this rule shall not be applicable to stations licensed to a network organization or to a subsidiary of a network organization.
(j)-(l) [Reserved]
(m) Territorial exclusivity in non-network arrangements. (1) No television station shall enter into any contract, arrangement, or understanding, expressed or implied; with a non-network program producer, distributor, or supplier, or other person; which prevents or hinders another television station located in a community over 56.3 kilometers (35 miles) away, as determined by the reference points contained in § 76.53 of this chapter, (if reference points for a community are not listed in § 76.53, the location of the main post office will be used) from broadcasting any program purchased by the former station from such non-network program producer, distributor, supplier, or other person, except that a television station may secure exclusivity against a television station licensed to another designated community in a hyphenated market specified in the market listing as contained in § 76.51 of this chapter for those 100 markets listed, and for markets not listed in § 76.51 of this chapter, the listing as contained in the Nielsen Media Research DMA Rankings for the most recent year at the time that the exclusivity contract, arrangement or understanding is complete under practices of the industry. As used in this paragraph, the term “community” is defined as the community specified in the instrument of authorization as the location of the station.
(2) Notwithstanding paragraph (m)(1) of this section, a television station may enter into a contract, arrangement, or understanding with a producer, supplier, or distributor of a non-network program if that contract, arrangement, or understanding provides that the broadcast station has exclusive national rights such that no other television station in the United States may broadcast the program.
Contracts, arrangements, or understandings that are complete under the practices of the industry prior to August 7, 1973, will not be disturbed. Extensions or renewals of such agreements are not permitted because they would in effect be new agreements without competitive bidding. However, such agreements that were based on the broadcaster's advancing “seed money” for the production of a specific program or series that specify two time periods—a tryout period and period thereafter for general exhibition—may be extended or renewed as contemplated in the basic agreement.
It is intended that the top 100 major television markets listed in § 76.51 of this chapter shall be used for the purposes of this rule and that the listing of the top 100 television markets appearing in the ARB Television Market Analysis shall not be used. The reference in this rule to the listing of markets in the ARB Television Market Analysis refers to hyphenated markets below the top-100 markets contained in the ARB Television Market Analysis. If a community is listed in a hyphenated market in § 76.51 and is also listed in one of the markets in the ARB listing, the listing in § 76.51 shall govern.
The provisions of this paragraph apply only to U.S. commercial television broadcast stations in the 50 states, and not to stations in Puerto Rico or the Virgin Islands, foreign stations or noncommercial educational television or “public” television stations (either by way of restrictions on their exclusivity or on exclusivity against them).
New stations authorized in any community of a hyphenated market listed in § 76.51 of this chapter or in any community of a hyphenated market listed in the ARB Television Market Analysis (for markets below the top-100 markets) are subject to the same rules as previously existing stations therein. New stations authorized in other communities are considered stations in separate markets unless and until § 76.51 is amended by Commission action, or the ARB listing is changed.
§§ 73.659-73.663   [Reserved]
§ 73.664   Determining operating power.
(a) Required method. The operating power of each TV transmitter shall normally be determined by the direct method.
(b) Direct method. The direct method of power determination for a TV transmitter uses the indications of a calibrated transmission line meter located at the RF output terminals of the transmitter. The indications of the calibrated meter are used to observe and maintain the authorized operating power of the transmitter. This meter must be calibrated whenever any component in the metering circuit is repaired or replaced and as often as necessary to ensure operation in accordance with the provisions of § 73.1560. The following calibration procedures are to be used:
(1) The transmission line meter is calibrated by measuring the average power at the output terminals of the transmitter, including any filters which may be used in normal operation. For this determination the average power output is measured while operating into a dummy load of substantially zero reactance and a resistance equal to the transmission line characteristic impedance.
(2) If electrical devices are used to determine the output power, such devices must permit determination of this power to within an accuracy of ±5% of the power indicated by the full scale reading of the electrical indicating instrument of the device. If temperature and coolant flow indicating devices are used to determine the power output, such devices must permit determination of this power to within an accuracy of ±4% of measured average power output. During this measurement the input voltage and current to the final radio frequency amplifier stage and the transmission line meter are to be read and compared with similar readings taken with the dummy load replaced by the antenna. These readings must be in substantial agreement.
(3) The meter must be calibrated with the transmitter operating at 80%, 100%, and 110% of the authorized power as often as may be necessary to maintain its accuracy and ensure correct transmitter operating power. In cases where the transmitter is incapable of operating at 110% of the authorized power output, the calibration may be made at a power output between 100% and 110% of the authorized power output. However, where this is done, the output meter must be marked at the point of calibration of maximum power output, and the station will be deemed to be in violation of this rule if that power is exceeded. The upper and lower limits of permissible power deviation as determined by the prescribed calibration, must be shown upon the meter either by means of adjustable red markers incorporated in the meter or by red marks placed upon the meter scale or glass face. These markings must be checked and changed, if necessary, each time the meter is calibrated.
(c) Indirect method. The operating power is determined by the indirect method by applying an appropriate factor to the input power to the final radio-frequency amplifier stage of the transmitter using the following formula:
(1) If the above formula is not appropriate for the design of the transmitter final amplifier, use a formula specified by the transmitter manufacturer with other appropriate operating parameters.
(2) The value of the efficiency factor, F established for the authorized transmitter output power is to be used for maintaining the operating power, even though there may be some variation in F over the power operating range of the transmitter.
(3) The value of F is to be determined and a record kept thereof by one of the following procedures listed in order of preference:
(i) Using the most recent measurement data for calibration of the transmission line meter according to the procedures described in paragraph (b) of this section or the most recent measurements made by the licensee establishing the value of F. In the case of composite transmitters or those in which the final amplifier stages have been modified pursuant to FCC approval, the licensee must furnish the FCC and also retain with the station records the measurement data used as a basis for determining the value of F.
(ii) Using measurement data shown on the transmitter manufacturer's test data supplied to the licensee, provided that measurements were made at the authorized channel and transmitter output power.
(iii) Using the transmitter manufacturer's measurement data.
§ 73.670   Commercial limits in children's programs.
(a) No commercial television broadcast station licensee shall air more than 10.5 minutes of commercial matter per hour during children's programming on weekends, or more than 12 minutes of commercial matter per hour on weekdays.
(b) The display of Internet Web site addresses during program material or promotional material not counted as commercial time is permitted only if the Web site:
(1) Offers a substantial amount of bona fide program-related or other noncommercial content;
(2) Is not primarily intended for commercial purposes, including either e-commerce or advertising;
(3) The Web site's home page and other menu pages are clearly labeled to distinguish the noncommercial from the commercial sections; and
(4) The page of the Web site to which viewers are directed by the Web site address is not used for e-commerce, advertising, or other commercial purposes (e.g., contains no links labeled “store” and no links to another page with commercial material).
(c) If an Internet address for a Web site that does not meet the test in paragraph (b) of this section is displayed during a promotion in a children's program, in addition to counting against the commercial time limits in paragraph (a) of this section the promotion must be clearly separated from program material.
(d)(1) Entities subject to commercial time limits under the Children's Television Act shall not display a Web site address during or adjacent to a program if, at that time, on pages that are primarily devoted to free noncommercial content regarding that specific program or a character appearing in that program:
(i) Products are sold that feature a character appearing in that program; or
(ii) A character appearing in that program is used to actively sell products.
(2) The requirements of this paragraph do not apply to:
(i) Third-party sites linked from the companies' Web pages;
(ii) On-air third-party advertisements with Web site references to third-party Web sites; or
(iii) Pages that are primarily devoted to multiple characters from multiple programs.
Commercial matter means air time sold for purposes of selling a product or service and promotions of television programs or video programming services other than children's or other age-appropriate programming appearing on the same channel or promotions for children's educational and informational programming on any channel.
For purposes of this section, children's programming refers to programs originally produced and broadcast primarily for an audience of children 12 years old and younger.
§ 73.671   Educational and informational programming for children.
(a) Each commercial and noncommercial educational television broadcast station licensee has an obligation to serve, over the term of its license, the educational and informational needs of children through both the licensee's overall programming and programming specifically designed to serve such needs.
(b) Any special nonbroadcast efforts which enhance the value of children's educational and informational television programming, and any special effort to produce or support educational and informational television programming by another station in the licensee's marketplace, may also contribute to meeting the licensee's obligation to serve, over the term of its license, the educational and informational needs of children.
(c) For purposes of this section, educational and informational television programming is any television programming that furthers the educational and informational needs of children 16 years of age and under in any respect, including the child's intellectual/cognitive or social/emotional needs. Programming specifically designed to serve the educational and informational needs of children (“Core Programming”) is educational and informational programming that satisfies the following additional criteria:
(1) It has serving the educational and informational needs of children ages 16 and under as a significant purpose;
(2) It is aired between the hours of 6:00 a.m. and 10:00 p.m.;
(3) It is a regularly scheduled weekly program, except that a licensee may air a limited amount of programming that is not regularly scheduled on a weekly basis, including educational specials and regularly scheduled non-weekly programming, and have that programming count as Core Programming, as described in paragraph (d) of this section;
(4) It is at least 30 minutes in length, except that a licensee may air a limited amount of short-form programming, including public service announcements and interstitials, and have that programming count as Core Programming, as described in paragraph (d) of this section;
(5) For commercial broadcast stations only, the program is identified as specifically designed to educate and inform children by the display on the television screen throughout the program of the symbol E/I;
(6) The target child audience is specified in writing in the licensee's Children's Television Programming Report, as described in § 73.3526(e)(11)(iii); and
(7) Instructions for listing the program as educational/informational are provided by the licensee to publishers of program guides, as described in § 73.673.
(d) The Commission will apply the processing guideline in this paragraph (d) to digital stations in assessing whether a television broadcast licensee has complied with the Children's Television Act of 1990 (“CTA”) on its digital channel(s). A digital television licensee will be deemed to have satisfied its obligation to air such programming and shall have the CTA portion of its license renewal application approved by the Commission staff if it has aired: At least three hours per week of Core Programming (as defined in paragraph (c) of this section and as averaged over a six-month period), or a total of 156 hours of Core Programming annually, including at least 26 hours per quarter of regularly scheduled weekly programming and up to 52 hours annually of Core Programming of at least 30 minutes in length that is not regularly scheduled weekly programming, such as educational specials and regularly scheduled non-weekly programming. A licensee will also been deemed to have satisfied the obligation in this paragraph (d) and be eligible for such staff approval if it has aired a total of 156 hours of Core Programming annually, including at least 26 hours per quarter of regularly scheduled weekly programming and up to 52 hours of Core Programming that is not regularly scheduled on a weekly basis, such as educational specials and regularly scheduled non-weekly programming, and short-form programs of less than 30 minutes in length, including public service announcements and interstitials. Licensees that multicast are permitted to air up to 13 hours per quarter of regularly scheduled weekly programming on a multicast stream. The remainder of a station's Core Programming must be aired on the station's primary stream. Licensees that do not meet the processing guidelines in this paragraph (d) will be referred to the Commission, where they will have full opportunity to demonstrate compliance with the CTA by relying in part on sponsorship of Core educational/informational programs on other stations in the market that increases the amount of Core educational and informational programming on the station airing the sponsored program and/or on special non-broadcast efforts which enhance the value of children's educational and informational television programming.
(e) A station that preempts an episode of a regularly scheduled weekly Core Program will be permitted to count the episode toward the processing guidelines set forth in paragraph (d) of this section as follows:
(1) A station that preempts an episode of a regularly scheduled weekly Core Program on its primary stream will be permitted to air the rescheduled episode on its primary stream at any time during Core Programming hours within seven days before or seven days after the date the episode was originally scheduled to air. The broadcast station must make an on-air notification of the schedule change during the same time slot as the preempted episode. If a station intends to air the rescheduled episode within the seven days before the date the episode was originally scheduled to air, the station must make the on-air notification during the same timeslot as the preceding week's episode of that program. If the station intends to air the rescheduled episode within the seven days after the date the preempted episode was originally scheduled to air, the station must make the on-air notification during the timeslot when the preempted episode was originally scheduled to air. The on-air notification must include the alternate date and time when the program will air.
(2) A station that preempts an episode of a regularly scheduled weekly Core Program on a multicast stream will be permitted to air the rescheduled episode on that same multicast stream at any time during Core Programming hours within seven days before or seven days after the date the episode was originally scheduled to air. The broadcast station must make an on-air notification of the schedule change during the same time slot as the preempted episode. If a station intends to air the rescheduled episode within the seven days before the date the episode was originally scheduled to air, the station must make the on-air notification during the same timeslot as the preceding week's episode of that program. If the station intends to air the rescheduled episode within the seven days after the date the preempted episode was originally scheduled to air, the station must make the on-air notification during the timeslot when the preempted episode was originally scheduled to air. The on-air notification must include the alternate date and time when the program will air.
(3) A station that preempts an episode of a regularly scheduled weekly Core Program to air non-regularly scheduled live programming produced locally by the station will not be required to reschedule the episode.
For purposes of determining under this section whether programming has a significant purpose of serving the educational and informational needs of children, the Commission will ordinarily rely on the good faith judgments of the licensee. Commission review of compliance with that element of the definition will be done only as a last resort.
§ 73.672   [Reserved]
§ 73.673   Public information initiatives regarding educational and informational programming for children.
Each commercial television broadcast station licensee shall provide information identifying programming specifically designed to educate and inform children to publishers of program guides.
§ 73.681   Definitions.
Antenna electrical beam tilt. The shaping of the radiation pattern in the vertical plane of a transmitting antenna by electrical means so that maximum radiation occurs at an angle below the horizontal plane.
Antenna height above average terrain. The average of the antenna heights above the terrain from approximately 3.2 (2 miles) to 16.1 kilometers (10 miles) from the antenna for the eight directions spaced evenly for each 45 degrees of azimuth starting with True North. (In general, a different antenna height will be determined in each direction from the antenna. The average of these various heights is considered the antenna height above the average terrain. Where circular or elliptical polarization is employed, the antenna height above average terrain shall be based upon the height of the radiation center of the antenna which transmits the horizontal component of radiation.
Antenna mechanical beam tilt. The intentional installation of a transmitting antenna so that its axis is not vertical, in order to change the normal angle of maximum radiation in the vertical plane.
Antenna power gain. The square of the ratio of the root-mean-square free space field strength produced at 1 kilometer in the horizontal plane, in millivolts per meter for one kW antenna input power to 221.4 mV/m. This ratio should be expressed in decibels (dB). (If specified for a particular direction, antenna power gain is based on the field strength in that direction only.)
Aspect ratio. The ratio of picture width to picture height as transmitted.
Auxiliary facility. An auxiliary facility is an antenna separate a from the main facility's antenna, permanently installed on the same tower or at a different location, from which a station may broadcast for short periods without prior Commission authorization or notice to the Commission while the main facility is not in operation (e.g., where tower work necessitates turning off the main antenna or where lightning has caused damage to the main antenna or transmission system) ( See § 73.1675).
Effective radiated power. The product of the antenna input power and the antenna power gain. This product should be expressed in kW and in dB above 1 kW (dBk). (If specified for a particular direction, effective radiated power is based on the antenna power gain in that direction only. The licensed effective radiated power is based on the maximum antenna power gain. When a station is authorized to use a directional antenna or an antenna beam tilt, the direction of the maximum effective radiated power will be specified.) Where circular or elliptical polarization is employed, the term effective radiated power is applied separately to the horizontally and vertically polarized components of radiation. For assignment purposes, only the effective radiated power authorized for the horizontally polarized component will be considered.
Equivalent isotropically radiated power (EIRP). The term “equivalent isotropically radiated power” (also known as “effective radiated power above isotropic”) means the product of the antenna input power and the antenna gain in a given direction relative to an isotropic antenna.
Free space field strength. The field strength that would exist at a point in the absence of waves reflected from the earth or other reflecting objects.
Interlaced scanning. A scanning process in which successively scanned lines are spaced an integral number of line widths, and in which the adjacent lines are scanned during successive cycles of the field frequency.
Polarization. The direction of the electric field as radiated from the transmitting antenna.
Standard television signal. A signal which conforms to the television transmission standards.
Synchronization. The maintenance of one operation in step with another.
Television broadcast band. The frequencies in the band extending from 54 to 608 megahertz which are assignable to television broadcast stations. These frequencies are 54 to 72 megahertz (channels 2 through 4), 76 to 88 megahertz (channels 5 and 6), 174 to 216 megahertz (channels 7 through 13), and 470 to 608 megahertz (channels 14 through 36).
Television broadcast station. A station in the television broadcast band transmitting simultaneous visual and aural signals intended to be received by the general public.
Television channel. A band of frequencies 6 MHz wide in the television broadcast band and designated either by number or by the extreme lower and upper frequencies.

(3) For availability of this material, contact ATSC (see § 73.8000 for contact information).
(e) Transmission of commercial advertisements by television broadcast station. (1) Mandatory compliance with ATSC A/85 RP. Effective December 13, 2012, television broadcast stations must comply with the ATSC A/85 RP incorporated by reference, see § 73.8000), insofar as it concerns the transmission of commercial advertisements.
(2) Commercials inserted by station. A television broadcast station that installs, utilizes, and maintains in a commercially reasonable manner the equipment and associated software to comply with ATSC A/85 RP shall be deemed in compliance with respect to locally inserted commercials, which for the purposes of this provision are commercial advertisements added to a programming stream by a station prior to or at the time of transmission to viewers. In order to be considered to have installed, utilized and maintained the equipment and associated software in a commercially reasonable manner, a television broadcast station must:
(i) Install, maintain and utilize equipment to properly measure the loudness of the content and to ensure that the dialnorm metadata value correctly matches the loudness of the content when encoding the audio into AC-3 for transmitting the content to the consumer;
(ii) Provide records showing the consistent and ongoing use of this equipment in the regular course of business and demonstrating that the equipment has undergone commercially reasonable periodic maintenance and testing to ensure its continued proper operation;
(iii) Certify that it either has no actual knowledge of a violation of the ATSC A/85 RP, or that any violation of which it has become aware has been corrected promptly upon becoming aware of such a violation; and
(iv) Certify that its own transmission equipment is not at fault for any pattern or trend of complaints.
(3) Embedded commercials—safe harbor. With respect to embedded commercials, which, for the purposes of this provision, are those commercial advertisements placed into the programming stream by a third party ( i.e. , programmer) and passed through by the station to viewers, a television broadcast station must certify that its own transmission equipment is not at fault for any pattern or trend of complaints, and may demonstrate compliance with the ATSC A/85 RP through one of the following methods:
(i) Relying on a network's or other programmer's certification of compliance with the ATSC A/85 RP with respect to commercial programming, provided that:
(A) The certification is widely available by Web site or other means to any television broadcast station, cable operator, or multichannel video programming distributor that transmits that programming; and
(B) The television broadcast station has no reason to believe that the certification is false; and
(C) The television broadcast station performs a spot check, as defined in § 73.682(e)(3)(iv)(A), (B), (D), and (E), on programming in response to an enforcement inquiry concerning a pattern or trend of complaints regarding commercials contained in that programming.
(ii) If transmitting any programming that is not certified as described in § 73.682(e)(3)(i), a television broadcast station that had more than $14,000,000 in annual receipts for the calendar year 2011 must perform annual spot checks, as defined in § 73.682(e)(3)(iv)(A), (B), (C), and (E), of all the non-certified commercial programming it receives from a network or other programmer and perform a spot check, as defined in § 73.682(e)(3)(iv)(A), (B), (D), and (E), on programming in response to an enforcement inquiry concerning a pattern or trend of complaints regarding commercials contained in that programming;
(iii) A television broadcast station that had $14,000,000 or less in annual receipts for the year 2011 need not perform annual spot checks but must perform a spot check, as defined in § 73.682(e)(3)(iv)(A), (B), (D), and (E), on programming in response to an enforcement inquiry concerning a pattern or trend of complaints regarding commercials contained in that programming.
(iv) For purposes of this section, a “spot check” of embedded commercials requires monitoring 24 uninterrupted hours of programming with an audio loudness meter employing the measurement technique specified in the ATSC A/85 RP, and reviewing the records from that monitoring to detect any commercials transmitted in violation of the ATSC A/85 RP. The television broadcast station must not inform the network or programmer of the spot check prior to performing it.
(A) Spot-checking must be conducted after the signal has passed through the television broadcast station's processing equipment (e.g., at the output of a television receiver). If a problem is found, the television broadcast station must determine the source of the noncompliance.
(B) To be considered valid, the television broadcast station must demonstrate appropriate maintenance records for the audio loudness meter.
(C) With reference to the annual “safe harbor” spot check in § 73.682(e)(3)(ii):
( 1 ) To be considered valid, the television broadcast station must demonstrate, at the time of any enforcement inquiry, that appropriate spot checks had been ongoing.
( 2 ) If there is no single 24 hour period in which all programmers of a given program stream are represented, an annual spot check may consist of a series of loudness measurements over the course of a 7 day period, totaling no fewer than 24 hours, that measure at least one program, in its entirety, provided by each non-certified programmer that supplies programming for that program stream.
( 3 ) If annual spot checks are performed for two consecutive years without finding evidence of noncompliance with the ATSC A/85 RP, no further annual spot checks are required to remain in the safe harbor for existing programming.
( 4 ) Non-certified program streams must be spot-checked annually using the approach described in this section. If annual spot checks of the program stream are performed for two consecutive years without finding evidence of noncompliance with the ATSC A/85 RP, no further annual spot checks are required to remain in the safe harbor for that program stream.
( 5 ) Even after the two year period for annual spot checks, if a spot check shows noncompliance on a non-certified program stream, the station must once again perform annual spot checks of that program stream to be in the safe harbor for that programming. If these renewed annual spot checks are performed for two consecutive years without finding additional evidence of noncompliance with the ATSC A/85 RP, no further annual spot checks are required to remain in the safe harbor for that program stream.
(D) With reference to the spot checks in response to an enforcement inquiry pursuant to § 73.682(e)(3)(i)(C), (2), or ( 3 ):
( 1 ) If notified of a pattern or trend of complaints, the television broadcast station must perform the 24-hour spot check of the program stream at issue within 30 days or as otherwise specified by the Enforcement Bureau; and
( 2 ) If the spot check reveals actual compliance, the television broadcast station must notify the Commission in its response to the enforcement inquiry.
(E) If any spot check shows noncompliance with the ATSC A/85 RP, the television station must notify the Commission and the network or programmer within 7 days, direct the programmer's attention to any relevant complaints, and must perform a follow-up spot check within 30 days of providing such notice. The station must notify the Commission and the network or programmer of the results of the follow-up spot check. Notice to the Federal Communications Commission must be provided to the Chief, Investigations and Hearings Division, Enforcement Bureau, or as otherwise directed in a Letter of Inquiry to which the station is responding.
( 1 ) If the follow-up spot check shows compliance with the ATSC A/85 RP, the station remains in the safe harbor for that program stream.
( 2 ) If the follow-up spot check shows noncompliance with the ATSC A/85 RP, the station will not be in the safe harbor with respect to commercials contained in the program stream for which the spot check showed noncompliance until a subsequent spot check shows that the program stream is in compliance.
(4) Use of a real-time processor. A television broadcast station that installs, maintains and utilizes a real-time processor in a commercially reasonable manner will be deemed in compliance with the ATSC A/85 RP with regard to any commercial advertisements on which it uses such a processor, so long as it also:
(i) Provides records showing the consistent and ongoing use of this equipment in the regular course of business and demonstrating that the equipment has undergone commercially reasonable periodic maintenance and testing to ensure its continued proper operation;
(ii) Certifies that it either has no actual knowledge of a violation of the ATSC A/85 RP, or that any violation of which it has become aware has been corrected promptly upon becoming aware of such a violation; and
(iii) Certifies that its own transmission equipment is not at fault for any pattern or trend of complaints.
(5) Commercials locally inserted by a station's agent—safe harbor. With respect to commercials locally inserted, which for the purposes of this provision are commercial advertisements added to a programming stream for the television broadcast station by a third party after it has been received from the programmer but prior to or at the time of transmission to viewers, a station may demonstrate compliance with the ATSC A/85 RP by relying on the third party local inserter's certification of compliance with the ATSC A/85 RP, provided that:
(i) The television broadcast station has no reason to believe that the certification is false;
(ii) The television broadcast station certifies that its own transmission equipment is not at fault for any pattern or trend of complaints; and
(iii) The television broadcast station performs a spot check, as defined in § 73.682(e)(3)(iv)(A), (B), (D), and (E), on the programming at issue in response to an enforcement inquiry concerning a pattern or trend of complaints regarding commercials inserted by that third party.
(6) Instead of demonstrating compliance pursuant to paragraphs (e)(2) through (5) of this section, a station may demonstrate compliance with paragraph (e)(1) of this section in response to an enforcement inquiry prompted by a pattern or trend of complaints by demonstrating actual compliance with ATSC A/85 RP with regard to the commercial advertisements that are the subject of the inquiry, and certifying that its own transmission equipment is not at fault for any such pattern or trend of complaints.
(7) For additional information regarding this requirement, see Implementation of the Commercial Advertisement Loudness Mitigation (CALM) Act, FCC 11-182.
(f) Next Gen TV broadcast television transmission standard authorized. (1) As an alternative to broadcasting only an ATSC 1.0 signal using the DTV transmission standard set forth in paragraph (d) of this section, DTV licensees or permittees may choose to broadcast an ATSC 3.0 signal using the Next Gen TV transmission standard set forth in this paragraph (f), provided it also broadcasts a simulcast signal in ATSC 1.0 (using the DTV transmission standard in § 73.682(d)).
(2)(i) Effective March 5, 2018, transmission of Next Gen TV broadcast television (ATSC 3.0) signals shall comply with the standards for such transmissions set forth in ATSC A/321:2016, “System Discovery and Signaling” (March 23, 2016) (incorporated by reference, see § 73.8000).

(b) - (c) [Reserved]
(d) For purposes of determining the eligibility of individual households for satellite retransmission of distant network signals under the copyright law provisions of 17 U.S.C. 119(d)(10)(A), field strength shall be determined by the Individual Location Longley-Rice (ILLR) propagation prediction model. Such eligibility determinations shall consider only the signals of network stations located in the subscriber's Designated Market Area. Guidance for use of the ILLR model in predicting the field strength of television signals for such determinations is provided in OET Bulletin No. 73. For availability of OET Bulletin No. 73, contact FCC (see § 73.8000 for contact information).
(e) If a location was predicted to be unserved by a local network station using a version of the ILLR model specified in OET Bulletin No. 72 or OET Bulletin No. 73, as appropriate, and the satellite subscriber at that location is receiving a distant signal affiliated with the same network from its satellite provider, the satellite subscriber shall remain eligible for receiving the distant signal from its satellite provider if that location is subsequently predicted to be served by the local station due to either a change in the ILLR model or a change in the station's operations that change its coverage.
(f) A satellite carrier is exempt from the verification requirements of 47 U.S.C. 339(c)(4)(A) with respect to a test requested by a satellite subscriber to whom the retransmission of the signals of local broadcast stations is available under 47 U.S.C. 338 from such carrier. The definitions of satellite carrier, subscriber, and local market contained in 47 CFR 76.66(a) apply to this paragraph (f).
§ 73.686   Field strength measurements.
(a) Except as provided for in § 73.612, television broadcast stations shall not be protected from any type of interference or propagation effect. Persons desiring to submit testimony, evidence or data to the Commission for the purpose of showing that the technical standards contained in this subpart do not properly reflect the levels of any given type of interference or propagation effect may do so only in appropriate rulemaking proceedings concerning the amendment of such technical standards. Persons making field strength measurements for formal submission to the Commission in rulemaking proceedings, or making such measurements upon the request of the Commission, shall follow the procedure for making and reporting such measurements outlined in paragraph (b) of this section. In instances where a showing of the measured level of a signal prevailing over a specific community is appropriate, the procedure for making and reporting field strength measurements for this purpose is set forth in paragraph (c) of this section.
(b) Collection of field strength data for propagation analysis —(1) Preparation for measurements. (i) On large scale topographic maps, eight or more radials are drawn from the transmitter location to the maximum distance at which measurements are to be made, with the angles included between adjacent radials of approximately equal size. Radials should be oriented so as to traverse representative types of terrain. The specific number of radials and their orientation should be such as to accomplish this objective.
(ii) At a point exactly 16.1 kilometers (10 miles) from the transmitter, each radial is marked, and at greater distances at successive 3.2 kilometer (2 mile) intervals. Where measurements are to be conducted at UHF, or over extremely rugged terrain, shorter intervals may be employed, but all such intervals shall be of equal length. Accessible roads intersecting each radial as nearly as possible at each 3.2 kilometer (2 mile) marker are selected. These intersections are the points on the radial at which measurements are to be made, and are referred to subsequently as measuring locations. The elevation of each measuring location should approach the elevation at the corresponding 3.2 kilometer (2 mile) marker as nearly as possible.
(2) Measurement procedure. The field strength of the visual carrier shall be measured with a voltmeter capable of indicating accurately the peak amplitude of the synchronizing signal. All measurements shall be made utilizing a receiving antenna designed for reception of the horizontally polarized signal component, elevated 9.1 meters (30 feet) above the roadbed. At each measuring location, the following procedure shall be employed.
(i) The instrument calibration is checked.
(ii) The antenna is elevated to a height of 30 feet.
(iii) The receiving antenna is rotated to determine if the strongest signal is arriving from the direction of the transmitter.
(iv) The antenna is oriented so that the sector of its response pattern over which maximum gain is realized is in the direction of the transmitter.
(v) A mobile run of at least 30.5 meters (100 feet) is made, which is centered on the intersection of the radial and the road, and the measured field strength is continuously recorded on a chart recorder over the length of the run.
(vi) The actual measuring location is marked exactly on the topographic map, and a written record, keyed to the specific location, is made of all factors which may affect the recorded field, such as topography, height and types of vegetation, buildings, obstacles, weather, and other local features.
(vii) If, during the test conducted as described in paragraph (b)(2)(iii) of this section, the strongest signal is found to come from a direction other than from the transmitter, after the mobile run prescribed in paragraph (b)(2)(v) of this section is concluded, additional measurements shall be made in a “cluster” of at least five fixed points. At each such point, the field strengths with the antenna oriented toward the transmitter, and with the antenna oriented so as to receive the strongest field, are measured and recorded. Generally, all points should be within 61.0 meters (200 feet) of the center point of the mobile run.
(viii) If overhead obstacles preclude a mobile run of at leat 30.5 meters (100 feet), a “cluster” of five spot measurements may be made in lieu of this run. The first measurement in the cluster is identified. Generally, the locations for other measurements shall be within 61.0 meters (200 feet) of the location of the first.
(3) Method of reporting measurements. A report of measurements to the Commission shall be submitted in affidavit form, in triplicate, and should contain the following information:
(i) Tables of field strength measurements, which, for each measuring location, set forth the following data:

(iii) A rectangular grid, of such size and shape as to encompass the boundaries of the community is drawn on an accurate map of the community. The number of line intersections on the grid included within the boundaries of the community shall be at least equal to the required number of measuring locations. The position of each intersection on the community map determines the location at which a measurement shall be made.
(2) Measurement procedure. The field strength of the visual carrier shall be measured, with a voltmeter capable of indicating accurately the peak amplitude of the synchronizing signal. All measurements shall be made utilizing a receiving antenna designed for reception of the horizontally polarized signal component, elevated 9.1 meter (30 feet) above street level.
(i) Each measuring location shall be chosen as close as feasible to a point indicated on the map, as previously prepared, and at as nearly the same elevation as that point as possible.
(ii) At each measuring location, after equipment calibration and elevation of the antenna, a check is made to determine whether the strongest signal arrives from a direction other than from the transmitter.
(iii) At 20 percent or more of the measuring locations, mobile runs, as described in paragraph (b)(2) of this section shall be made, with no less than three such mobile runs in any case. The points at which mobile measurements are made shall be well separated. Spot measurements may be made at other measuring points.
(iv) Each actual measuring location is marked exactly on the map of the community, and suitably keyed. A written record shall be maintained, describing, for each location, factors which may affect the recorded field, such as the approximate time of measurement, weather, topography, overhead wiring, heights and types of vegetation, buildings and other structures. The orientation, with respect to the measuring location shall be indicated of objects of such shape and size as to be capable of causing shadows or reflections. If the strongest signal received was found to arrive from a direction other than that of the transmitter, this fact shall be recorded.
(3) Method of reporting measurements. A report of measurements to the Commission shall be submitted in affidavit form, in triplicate, and should contain the following information:
(i) A map of the community showing each actual measuring location, specifically identifying the points at which mobile runs were made.

(vi) A list of calibrated equipment used for the measurements, which for each instrument, specifies its manufacturer, type, serial number and rated accuracy, and the date of its most recent calibration by the manufacturer, or by a laboratory. Complete details of any instrument not of standard manufacture shall be submitted.
(vii) A detailed description of the procedure employed in the calibration of the measuring equipment, including field strength meters measuring antenna, and connecting cable.
(d) [Reserved]
(e) Collection of field strength data to determine television signal intensity at an individual location—cluster measurements —(1) Preparation for measurements —(i) Testing antenna. The test antenna shall be either a standard half-wave dipole tuned to the center frequency of the channel being tested or a gain antenna provided its antenna factor for the channel(s) under test has been determined. Use the antenna factor supplied by the antenna manufacturer as determined on an antenna range.
(ii) Testing locations —At the test site, choose a minimum of five locations as close as possible to the specific site where the site's receiving antenna is located. If there is no receiving antenna at the site, choose a minimum of five locations as close as possible to a reasonable and likely spot for the antenna. The locations shall be at least three meters apart, enough so that the testing is practical. If possible, the first testing point should be chosen as the center point of a square whose corners are the four other locations. Calculate the median of the five measurements (in units of dBµ) and report it as the measurement.
(iii) Multiple signals —
(A) If more than one signal is being measured ( i.e., signals from different transmitters), use the same locations to measure each signal.
(B) For establishing eligibility of a satellite subscriber to receive distant network signals, only stations affiliated with the network in question that are located in the same Nielsen Designated Market Area (DMA) as the test site may be considered and tested.
(2) Measurement procedure. Measurements shall be made in accordance with good engineering practice and in accordance with this section of this chapter. At each measuring location, the following procedure shall be employed:
(i) Testing equipment. Perform an on-site calibration of the test instrument in accordance with the manufacturer's specifications. Tune a calibrated instrument to the center of the channel being tested. Measure the integrated average power over the full 6 megahertz bandwidth of the television signal. The intermediate frequency of the instrument should be set to 100 kilohertz unless the instrument is specifically designed by the manufacturer to use an alternative i.f. setting. The instrument must be capable of integrating over the selected i.f. for the 6 megahertz channel bandwidth. Take all measurements with a horizontally polarized antenna. Use a shielded transmission line between the testing antenna and the field strength meter. Match the antenna impedance to the transmission line at all frequencies measured, and, if using an un-balanced line, employ a suitable balance. Take account of the transmission line loss for each frequency being measured.
(ii) Weather. Do not take measurements during periods of inclement weather, including, but not limited to, periods of heavy rainfall, snowfall accumulation, high windspeed, or any combination thereof.
(iii) Antenna elevation. When field strength is being measured for a one-story building, elevate the testing antenna to 6.1 meters (20 feet) above the ground. In situations where the field strength is being measured for a building taller than one-story, elevate the testing antenna 9.1 meters (30 feet) above the ground.
(iv) Antenna orientation. Orient the testing antenna in the direction which maximizes the value of field strength for the signal being measured. If more than one station's signal is being measured, orient the testing antenna separately for each station.
(3) Written record shall be made and shall include at least the following:
(i) A list of calibrated equipment used in the field strength survey, which for each instrument specifies the manufacturer, type, serial number and rated accuracy, and the date of the most recent calibration by the manufacturer or by a laboratory.

(ii) A detailed description of the calibration of the measuring equipment, including field strength meters, measuring antenna, and connecting cable.
(iii) For each spot at the measuring site, all factors which may affect the recorded field, such as topography, height and types of vegetation, buildings, obstacles, weather, and other local features.
(iv) A description of where the cluster measurements were made.
(v) Time and date of the measurements and signature of the person making the measurements.
(vi) For each channel being measured, a list of the measured value of field strength (in units of dBµ after adjustment for line loss and antenna factor) of the five readings made during the cluster measurement process, with the median value highlighted.

(n) Optimum working frequency ( FOT ). The highest frequency which is returned by ionospheric radio propagation to the surface of the earth for a particular path and time of day for 90 percent of the days of the reference month.
The international abbreviation for optimum working frequency, FOT, is formed with the initial letters of the French words for “optimum working frequency” which are “frequence optimum de travail.”
(o) Zone of reception. Any geographic zone indicated in § 73.703 in which the reception of particular programs is specifically intended and in which broadcast coverage is contemplated.
(p) Area of reception. Any geographic area smaller than a zone of reception in which the reception of particular programs is specifically intended and in which broadcast coverage is contemplated, such areas being indicated by countries or parts of countries.
(q) Delivered median field strength, or field strength. The field strength incident upon the zone or area of reception expressed in microvolts per meter, or decibels above one microvolt per meter, which is exceeded by the hourly median value for 50 percent of the days of the reference month.
(r) Carrier power. The average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle under conditions of no modulation.
§ 73.702   Assignment and use of frequencies.
(a) Frequencies will be assigned by the Commission prior to the start of each season to authorized international broadcasting stations for use during the season at specified hours and for transmission to specified zones or areas of reception, with specified power and antenna bearing. Six months prior to the start of each season, licensees and permittees shall by informal written request, submitted to the Commission electronically in the International Communications Filing System (ICFS), indicate for the season the frequency or frequencies desired for transmission to each zone or area of reception specified in the license or permit, the specific hours during which it desires to transmit to such zones or areas on each frequency, and the power, antenna gain, and antenna bearing it desires to use.  Requests will be honored to the extent that interference and propagation conditions permit and that they are otherwise in accordance with the provisions of this section.
(b) After necessary processing of the requests required by paragraph (a) of this section, the Commission will notify each licensee and permittee of the frequencies, hours of use thereof to specified zones or areas of reception, power, and antenna bearing which it intends to authorize for the season in question. After receipt of such notification, the licensee or permittee shall, in writing, not later than two months before the start of the season in question, electronically inform the Commission in ICFS either that it plans to operate in accordance with the authorization which the Commission intends to issue, or that it plans to operate in another manner. If the licensee or permittee indicates that it plans to operate in another manner, it shall furnish explanatory details.
(c) If after submitting the request required under the provisions of paragraph (a) of this section, but before receipt of the Commission's notification referred to in paragraph (b) of this section, the licensee or permittee submits a request for changes of its original request electronically in ICFS such requests will be accepted for consideration only if accompanied by statements showing good cause therefor and will be honored only if conditions permit. If the information required to be submitted by the licensee or permittee under the provisions of paragraph (b) of this section indicates that operation in another manner is contemplated, and the explanatory details contain a request for change in the originally proposed manner of operation, such requests will be accepted for consideration only if accompanied by statements showing good cause therefor and will be honored only if conditions permit. If after the licensee or permittee submits the information required under the provisions of paragraph (b) of this section, but before the start of the season in question, the licensee or permittee submits electronically in ICFS a request for changes in its manner of operation for the season in question, the request will be accepted for consideration only if accompanied by statements showing good cause therefor and will be honored only if conditions permit. If after the start of a season the licensee or permittee submits a request for changes in the manner of operation as authorized, the request will be considered only if accompanied by statements showing good cause therefor, and will be honored only if conditions permit.
(d) The provisions of paragraphs (a), (b), and (c) of the section shall apply to licensees, to permittees operating under program test authority, and to permittees who anticipate applying for and receiving program test authority for operation during the specified season. Permittees who during the process of construction wish to engage in equipment tests shall by informal written request, submitted to the Commission electronically in ICFS not less than 30 days before they desire to begin such testing, indicate the frequencies they desire to use for testing and the hours they desire to use those frequencies. No equipment testing shall occur until the Commission has authorized frequencies and hours for such testing. Such authorizations shall be only for one season, and if it is desired to continue equipment testing in a following season, new requests for frequencies and hours must be submitted at least 30 days before it is desired to begin testing in the following season.
(e) Within 14 days after the end of each season, a report shall be filed with the Commission electronically in ICFS by each licensee or permittee operating under program test authority who has been issued a seasonal schedule for that season. The report shall state whether the licensee or permittee has operated the number of frequency-hours authorized by the seasonal schedule to each of the zones or areas of reception specified in the schedule. If such operation has not occurred, a detailed explanation of that fact shall also be submitted which includes specific dates, frequency-hours not used, and reasons for the failure to operate as authorized. The report shall also contain information that has been received by the licensee or permittee as to reception or interference, and conclusions with regard to propagation characteristics of frequencies that were assigned for the season in question.
(f) Assigned frequencies. To the extent practicable, the frequencies assigned to international broadcast stations shall be within the following frequency bands, which are allocated to the broadcasting service on a primary and exclusive basis, except as noted in paragraph (f)(1)(ii) of this section:
(1) In all Regions:
(i) Exclusive: 5,900-6,200 kHz; 7,300-7,350 kHz; 9,400-9,900 kHz; 11,600-12,100 kHz; 13,570-13,870 kHz; 15,100-15,800 kHz; 17,480-17,900 kHz; 18,900-19,020 kHz; 21,450-21,850 kHz; and 25,670-26,100 kHz.
(ii) Co-primary: 7,350-7,400 kHz, except in the countries listed in 47 CFR 2.106, footnote 5.143C, where this band is also allocated to the fixed service on a primary basis.
(2) In Region 1 and Region 3: 7,200-7,300 kHz and 7,400-7,450 kHz.
For the allocation of frequencies, the ITU has divided the world into three Regions, which are defined in 47 CFR 2.104(b). The bands 7,200-7,300 kHz and 7,400-7,450 kHz are not allocated to the broadcasting service in Region 2. Subject to not causing harmful interference to the broadcasting service, fixed and mobile services may operate in certain of the international broadcasting bands; see 47 CFR 2.106, footnotes 5.136, 5.143, 5.143A, 5.143B, 5.143D, 5.146, 5.147, and 5.151.
(g) [Reserved]
(h) Requirements for Regional operation. (1) Frequency assignments in the bands 7,200-7,300 kHz and 7,400-7,450 kHz shall be restricted to international broadcast stations in the Pacific insular areas that are located in Region 3 (as defined in 47 CFR 2.105(a), note 3) that transmit to geographical zones and areas of reception in Region 1 or Region 3.
(2) During the hours of 0800-1600 UTC (Coordinated Universal Time) antenna gain with reference to an isotropic radiator in any easterly direction that would intersect any area in Region 2 shall not exceed 2.15 dBi, except in the case where a transmitter power of less than 100 kW is used. In this case, antenna gain on restricted azimuths shall not exceed that which is determined in accordance with equation below. Stations desiring to operate in this band must submit sufficient antenna performance information electronically in ICFS to ensure compliance with these restrictions.Permitted gain for transmitter powers less than 100 kW:
(i) Frequencies requested for assignment must be as near as practicable to the optimum working frequency (unless otherwise justified) for the zone or area of reception for the period and path of transmission, and should be chosen so that a given frequency will provide the largest period of reliable transmission to the selected zone or area of reception. Moreover, at the zone or area of reception frequencies shall provide protection to the transmissions of other broadcasting stations which, in the opinion of the Commission, have priority of assignment.
(1) Requests for frequency-hours shall be accompanied by all pertinent technical data with reference to the frequencies and hours of operation, including calculated field strengths delivered to the zones or areas of reception.
(2) It is preferable that calculated field strengths delivered to zones or areas of reception be equal to or greater than those required by I.F.R.B. Technical Standards, Series A (and supplements thereto), in order for the I.F.R.B. to afford the notified assignment protection from interference. Nevertheless, calculated field strengths less than those required by the I.F.R.B. standards for protection will be acceptable to the Commission. However, licensees should note that if such lesser field strengths are submitted no protection from interference will be provided by the I.F.R.B. if their technical examination of such notifications show incompatibilities with other notified assignments fully complying with I.F.R.B. technical standards.
(3) Licensees are permitted to engage in multiple operation as defined in § 73.701(d).
(4) Seasonal requests for frequency-hours will be only for transmissions to zones or areas of reception specified in the basic instrument of authorization. Changes in such zones or areas will be made only on separate application for modification of such instruments made electronically in ICFS.
(j) Not more than one frequency will be assigned for use at any one time for any one program transmission except in instances where a program is intended for reception in more than one zone or area of reception and the intended zones or areas cannot be served by a single frequency: Provided, however, That on a showing of good cause made electronically in ICFS a licensee may be authorized to operate on more than one frequency at any one time to transmit any one program to a single zone or area of reception.
(k) Any frequency assigned to a licensee or permittee shall also be available for assignment to other licensees or permittees.
(l) All assignments of frequencies and the hours during which they will be used will be made with the express understanding that they are subject to immediate cancellation or change without hearing whenever the Commission determines that interference or propagation conditions so require and that each frequency-hour assignment for a given seasonal schedule is unique unto itself and not necessarily available for use during a subsequent season.
(m) The total maximum number of frequency-hours which will be authorized to all licensees of international broadcasting stations during any one day for any season is 100. The number of frequency-hours allocated to any licensee will depend on past usage, availability, and need. If for a forthcoming season the total of the requests for daily frequency-hours of all licensees exceeds 100, all licensees will be notified and each licensee that makes an adequate showing electronically in ICFS that good cause exists for not having its requested number of frequency-hours reduced and that operation of its station without such reduction would be consistent with the public interest may be authorized the frequency-hours requested.
The provisions of this paragraph are not to be construed to mean that a total of 100 (or more) frequency-hours per day is assured licensees. Frequency-hours will only be assigned to the extent that they are available. It is the responsibility of each licensee to make all technical studies to show that frequency-hours requested by it are available and suitable for use as proposed.
§ 73.703   Geographical zones and areas of reception.
The zones or areas of reception to be served by international broadcasting stations shall be based on the following map, and directive antennas shall be employed to direct transmissions thereto:
§ 73.712   Equipment tests.
(a) During the process of construction of an international broadcasting station, the permittee, having obtained authorization for frequencies and hours as set forth in the Note to § 73.702(d) may, without further authority of the FCC, conduct equipment tests for the purpose of such adjustments and measurements as may be necessary to assure compliance with the terms of the construction permit, the technical provisions of the application therefor and the rules and regulations. Such tests shall use voice identification and test tones only. No programming shall be conducted during equipment tests.
(b) The Commission may notify the permittee to conduct no tests or may cancel, suspend, or change the date for the beginning of equipment tests when and if such action may appear to be in the public interest, convenience, and necessity.
(c) Equipment tests may be continued so long as the construction permit shall remain valid: Provided, however, That the procedure set forth in paragraph (a) of this section must be repeated prior to the conducting of such tests in each season after the season in which the testing began.
(d) The authorization for tests embodied in this section shall not be construed as constituting a license to operate but as a necessary part of construction.
§ 73.713   Program tests.
(a) Upon completion of construction of an international broadcasting station in accordance with the terms of the construction permit, the technical provisions of the application therefor, and the rules and regulations and the applicable engineering standards, and when an application for station license has been filed showing the station to be in satisfactory operating condition, the permittee may request authority to conduct program tests. Such request shall be electronically filed with the FCC in the International Communications Filing System (ICFS) at least 10 days prior to the date on which it is desired to begin such operation.  All data necessary to show compliance with the terms and conditions of the construction permit must be filed with the license application.
(b) Program tests shall not commence until specific Commission authority is received. The Commission reserves the right to change the date of the beginning of such tests or to suspend or revoke the authority for program tests as and when such action may appear to be in the public interest, convenience, and necessity.
(c) Unless sooner suspended or revoked, program test authority continues valid during Commission consideration of the application for license and during this period further extension of the construction permit is not required. Program test authority shall be automatically terminated by final determination upon the application for station license.
(d) All operation under program test authority shall be in strict compliance with the rules governing international broadcasting stations and in strict accordance with representations made in the application for license pursuant to which the tests were authorized.
(e) The granting of program test authority shall not be construed as approval by the Commission of the application for station license.
§ 73.731   Licensing requirements.
(a) A license for an international broadcasting station will be issued only after a satisfactory showing has been made in regard to the following, among others:
(1) That there is a need for the international broadcasting service proposed to be rendered.
(2) That the necessary program sources are available to the applicant to render the international service proposed.
(3) That the production of the program service and the technical operation of the proposed station will be conducted by qualified persons.
(4) That the applicant is legally, technically and financially qualified and possesses adequate technical facilities to carry forward the service proposed.
(5) That the public interest, convenience and necessity will be served through the operation of the proposed station.
§ 73.732   Authorizations.
Authorizations issued to international broadcasting stations by the Commission will be authorizations to permit the construction or use of a particular transmitting equipment combination and related antenna systems for international broadcasting, and to permit broadcasting to zones or areas of reception specified on the instrument of authorization. The authorizations will not specify the frequencies to be used or the hours of use. Requests for frequencies and hours of use will be made by electronic filing in the International Communications Filing System (ICFS) as provided in § 73.702. Seasonal schedules, when issued pursuant to the provisions of § 73.702, will become attachments to and part of the instrument of authorization, replacing any such prior attachments.
§ 73.733   Normal license period.
All international broadcast station licenses will be issued so as to expire at the hour of 3 a.m. local time and will be issued for a normal period of 8 years expiring November 1.
§ 73.751   Operating power.
No international broadcast station shall be authorized to install, or be licensed for operation of, transmitter equipment with:
(a) A rated carrier power of less than 50 kilowatts (kW) if double-sideband (DSB) modulation is used,
(b) A peak envelope power of less than 50 kW if single-sideband (SSB) modulation is used, or
(c) A mean power of less than 10 kW if digital modulation is used.
§ 73.753   Antenna systems.
All international broadcasting stations shall operate with directional antennas. Such antennas shall be designed and operated so that the radiated power in the maximum lobe toward the specific zone or area of reception intended to be served shall be at least 10 times the average power from the antenna in the horizontal plane. Radiation in all other directions shall be suppressed to the maximum extent technically feasible. In order to eliminate or mitigate harmful interference, the direction of the maximum lobe may be adjusted upon approval of the Commission.
§ 73.754   Frequency monitors.
(a) The licensee of each international broadcast station shall operate a frequency monitor at the transmitter independent of the frequency control of the transmitter.
(b) The frequency monitor shall be designed and constructed in accordance with good engineering practice. It shall have an accuracy sufficient to determine that the operating frequency is within one-half of the allowed tolerance.
§ 73.755   Modulation monitors.
The licensee of each international broadcast station shall have a modulation monitor in operation at the transmitter.
§ 73.756   System specifications for double-sideband (DBS) modulated emissions in the HF broadcasting service.
(a) Channel spacing. The nominal spacing for DSB shall be 10 kHz. However, the interleaved channels with a separation of 5 kHz may be used in accordance with the relative protection criteria, provided that the interleaved emission is not to the same geographical area as either of the emissions between which it is interleaved.
(b) Emission characteristics —(1) Nominal carrier frequencies. Nominal carrier frequencies shall be integral multiples of 5 kHz.
(2) Audio-frequency band. The upper limit of the audio-frequency band (at—3 dB) of the transmitter shall not exceed 4.5 kHz and the lower limit shall be 150 Hz, with lower frequencies attenuated at a slope of 6 dB per octave.
(3) Modulation processing. If audio-frequency signal processing is used, the dynamic range of the modulating signal shall be not less than 20 dB.
(4) Necessary bandwidth. The necessary bandwidth shall not exceed 9 kHz.
§ 73.757   System specifications for single-sideband (SSB) modulated emissions in the HF broadcasting service.
(a) System parameters —(1) Channel spacing. In a mixed DSB, SSB and digital environment (see Resolution 517 (Rev.WRC-03)), the channel spacing shall be 10 kHz. In the interest of spectrum conservation, it is also permissible to interleave SSB emissions midway between two adjacent DSB channels, i.e. , with 5 kHz separation between carrier frequencies, provided that the interleaved emission is not to the same geographical area as either of the emissions between which it is interleaved. In an all inclusive SSB environment, the channel spacing and carrier frequency separation shall be 5 kHz.
(2) Equivalent sideband power. When the carrier reduction relative to peak envelope power is 6 dB, an equivalent SSB emission is one giving the same audio-frequency signal-to-noise ratio at the receiver output as the corresponding DSB emission, when it is received by a DSB receiver with envelope detection. This is achieved when the sideband power of the SSB emission is 3 dB larger than the total sideband power of the DSB emission. (The peak envelope power of the equivalent SSB emission and the carrier power are the same as that of the DSB emission.)
(b) Emission characteristics —(1) Nominal carrier frequencies. Nominal carrier frequencies shall be integral multiples of 5 kHz.
(2) Frequency tolerance. The frequency tolerance shall be 10 Hz.
The ITU suggests that administrations avoid carrier frequency differences of a few hertz, which cause degradations similar to periodic fading. This could be avoided if the frequency tolerance were 0.1 Hz, a tolerance which would be suitable for SSB emissions.
The SSB system adopted for the bands allocated exclusively to HF broadcasting does not require a frequency tolerance less than 10 Hz. The degradation mentioned in Note 1 occurs when the ratio of wanted-to-interfering signal is well below the required protection ratio. This remark is equally valid for both DSB and SSB emissions.
(3) Audio-frequency band. The upper limit of the audio-frequency band (at—3 dB) of the transmitter shall not exceed 4.5 kHz with a further slope of attenuation of 35 dB/kHz and the lower limit shall be 150 Hz with lower frequencies attenuated at a slope of 6 dB per octave.
(4) Modulation processing. If audio-frequency signal processing is used, the dynamic range of the modulating signal shall be not less than 20 dB.
(5) Necessary bandwidth. The necessary bandwidth shall not exceed 4.5 kHz.
(6) Carrier reduction (relative to peak envelope power). In a mixed DSB, SSB and digital environment, the carrier reduction shall be 6 dB to allow SSB emissions to be received by conventional DSB receivers with envelope detection without significant deterioration of the reception quality.
(7) Sideband to be emitted. Only the upper sideband shall be used.
(8) Attenuation of the unwanted sideband. The attenuation of the unwanted sideband (lower sideband) and of intermodulation products in that part of the emission spectrum shall be at least 35 dB relative to the wanted sideband signal level. However, since there is in practice a large difference between signal amplitudes in adjacent channels, a greater attenuation is recommended.
§ 73.758   System specifications for digitally modulated emissions in the HF broadcasting service.
(a) For digitally modulated emissions, the Digital Radio Mondiale (DRM) standard shall be employed. Both digital audio broadcasting and datacasting are authorized. The RF requirements for the DRM system are specified in paragraphs (b) and (c), of this section.
(b) System parameters —(1) Channel spacing. The initial spacing for digitally modulated emissions shall be 10 kHz. However, interleaved channels with a separation of 5 kHz may be used in accordance with the appropriate protection criteria appearing in Resolution 543 (WRC-03), provided that the interleaved emission is not to the same geographical area as either of the emissions between which it is interleaved.
(2) Channel utilization. Channels using digitally modulated emissions may share the same spectrum or be interleaved with analog emissions in the same high frequency broadcasting (HFBC) band, provided the protection afforded to the analog emissions is at least as great as that which is currently in force for analog-to-analog protection. Accomplishing this may require that the digital spectral power density (and total power) be lower by several dB than is currently used for either DSB or SSB emissions.
(c) Emission characteristics —(1) Bandwidth and center frequency. A full digitally modulated emission will have a 10 kHz bandwidth with its center frequency at any of the 5 kHz center frequency locations in the channel raster currently in use within the HFBC bands. Among several possible “simulcast” modes are those having a combination of analog and digital emissions of the same program in the same channel, that may use a digital emission of 5 kHz or 10 kHz bandwidth, next to either a 5 kHz or 10 kHz analog emission. In all cases of this type, the 5 kHz interleaved raster used in HFBC shall be adhered to in placing the emission within these bands.
(2) Frequency tolerance. The frequency tolerance shall be 10 Hz. See Section 73.757(b)(2), notes 1 and 2.
(3) Audio-frequency band. The quality of service, using digital source coding within a 10 kHz bandwidth, taking into account the need to adapt the emission coding for various levels of error avoidance, detection and correction, can range from the equivalent of monophonic FM (approximately 15 kHz) to the low-level performance of a speech codec (of the order of 3 kHz). The choice of audio quality is connected to the needs of the broadcaster and listener, and includes the consideration of such characteristics as the propagation conditions expected. There is no single specification, only the upper and lower bounds noted in this paragraph.
(4) Modulation. Quadrature amplitude modulation (QAM) with orthogonal frequency division multiplexing (OFDM) shall be used. 64-QAM is feasible under many propagation conditions; others such as 32-, 16- and 8-QAM are specified for use when needed.
(5) RF protection ratio values. The protection ratio values for analogue and digital emissions for co-channel and adjacent channel conditions shall be in accordance with Resolution 543 (WRC-03) as provisional RF protection ratio values subject to revision or confirmation by a future competent conference.
§ 73.759   Auxiliary transmitters.
Upon showing that a need exists for the use of auxiliary transmitters, a license may be issued provided that:
(a) Auxiliary transmitters may be installed either at the same location as the main transmitters or at another location.
(b) [Reserved]
(c) The auxiliary transmitters shall be maintained so that they may be put into immediate operation at any time for the following purposes:
(1) The transmission of the regular programs upon the failure of the main transmitters.
(2) The transmission of regular programs during maintenance or modification work on the main transmitter, necessitating discontinuance of its operation for a period not to exceed 5 days. (This includes the equipment changes which may be made without authority as set forth elsewhere in the rules and regulations or as authorized by the Commission by letter or by construction permit. Where such operation is required for periods in excess of 5 days, request therefor shall be made electronically in the International Communications Filing System (ICFS) in accordance with § 73.3542).
(3) Upon request by a duly authorized representative of the Commission.
(d) The auxiliary transmitters shall be tested at least once each week to determine that they are in proper operating condition and that they are adjusted to the proper frequency except that in the case of operation in accordance with paragraph (c) of this section during any week, the test in that week may be omitted provided the operation under paragraph (c) of this section is satisfactory. A record shall be kept of the time and result of each test. Such records shall be retained for a period of two years.
(e) The auxiliary transmitters shall be equipped with satisfactory control equipment which will enable the maintenance of the frequency emitted by the station within the limits prescribed by the regulations in this part.
(f) The operating power of an auxiliary transmitter may be less but not greater than the authorized power of the main transmitters.
§ 73.760   Alternate main transmitters.
The licensee of an international broadcast station may be licensed for alternate main transmitters provided that a technical need for such alternate transmitters is shown and that the following conditions are met: Both transmitters:
(a) Are located at the same place;
(b) Shall have the same power rating; and
(c) Shall meet the construction, installation, operation, and performance requirements of good engineering practice.
§ 73.761   Modification of transmission systems.
Specific authority, upon electronic filing of a formal application (FCC Form 309) therefor in the International Communications Filing System (ICFS), is required for any of the following changes:
(a) Change involving an increase or decrease in the power rating of the transmitters.
(b) A replacement of the transmitters as a whole.
(c) Change in the location of the transmitting antenna.
(d) Change in the power delivered to the antenna.
(e) Change in frequency control and/or modulation system.
(f) Change in direction or gain of antenna system.
(g) Other changes, not specified above in this section, may be made at any time without the authority of the Commission: Provided, That the Commission shall be immediately notified electronically in ICFS thereof and such changes shall be shown in the next application for renewal of license.
§ 73.762   Time of operation.
(a) All international broadcasting stations shall operate in accordance with the times indicated on their seasonal schedules.
(b) In the event that causes beyond a licensee's control make it impossible to adhere to the seasonal schedule or to continue operating, the station may limit or discontinue operation for a period of not more than 10 days, without further authority from the FCC. However, in such cases, the FCC shall be immediately notified by electronic filing in the International Communications Filing System (ICFS) of such limitation or discontinuance of operation and shall subsequently be notified by electronic filing in ICFS when the station resumes regular operation.
(c) In the event that causes beyond a licensee's control make it impossible to adhere to the seasonal schedule or to continue operating for a temporary period of more than 10 days, the station may not limit or discontinue operation until it requests and receives specific authority to do so from the FCC by electronic filing in ICFS. When the station subsequently resumes regular operation after such limited operation or discontinuance of operation, it shall notify the FCC in Washington, DC by electronic filing in ICFS. The license of a broadcasting station that fails to transmit broadcast signals for any consecutive 12-month period expires as a matter of law at the end of that period, notwithstanding any provision, term, or condition of the license to the contrary.
§ 73.765   Determining operating power.
The operating power specified in § 73.751 shall be determined by use of a calibrated dummy load or by any other method specified by the licensee and accepted by the Commission. Such method may subsequently be used by the licensee to maintain the authorized operating power.
§ 73.766   [Reserved]
§ 73.781   Logs.
The licensee or permittee of each international broadcast station must maintain the station log in the following manner:
(a) In the program log:
(1) An entry of the time each station identification announcement (call letters and location) is made.
(2) An entry briefly describing each program broadcast, such as “music”, “drama”, “speech”, etc., together with the name or title thereof, language, and the sponsor's name, with the time of the beginning and ending of the complete program.
(3) For each program of network origin, an entry showing the name of the network originating the program.
§ 73.782   Retention of logs.
Logs of international broadcast stations shall be retained by the licensee or permittee for a period of two years: Provided, however, That logs involving communications incident to a disaster or which include communications incident to or involved in an investigation by the Commission and concerning which the licensee or permittee has been notified, shall be retained by the licensee or permittee until he is specifically authorized in writing by the Commission to destroy them: Provided, further, That logs incident to or involved in any claim or complaint of which the licensee or permittee has notice shall be retained by the licensee or permittee until such claim or complaint has been fully satisfied or until the same has been barred by statute limiting the time for the filing of suits upon such claims.
§ 73.787   Station identification.
(a) A licensee of an international broadcast station shall make station identification announcement (call letters and location), at the beginning and ending of each time of operation and during the operation on the hour.
(b) Station identification, program announcements, and oral continuity shall be made with international significance (language particularly) which is designed for the foreign country or countries for which the service is primarily intended.
§ 73.788   Service; commercial or sponsored programs.
(a) A licensee of an international broadcast station shall render only an international broadcast service which will reflect the culture of this country and which will promote international goodwill, understanding, and cooperation. Any program solely intended for and directed to an audience in the continental United States does not meet the requirements for this service.
(b) Such international broadcast service may include commercial or sponsored programs: Provided, That:
(1) Commercial program continuities give no more than the name of the sponsor of the program and the name and general character of the commodity, utility or service, or attraction advertised.
(2) In case of advertising a commodity, the commodity is regularly sold or is being promoted for sale on the open market in the foreign country or countries to which the program is directed in accordance with paragraph (c) of this section.
(3) In case of advertising an American utility or service to prospective tourists or visitors to the United States, the advertisement continuity is particularly directed to such persons in the foreign country or countries where they reside and to which the program is directed in accordance with paragraph (c) of this section.
(4) In case of advertising an international attraction (such as a world fair, resort, spa, etc.) to prospective tourists or visitors to the United States, the oral continuity concerning such attraction is consistent with the purpose and intent of this section.
(5) In case of any other type of advertising, such advertising is directed to the foreign country or countries to which the program is directed and is consistent with the purpose and intent of this section.
(c) The geographic areas to be served by international broadcasting stations are the zones and areas of reception shown in § 73.703.
(d) An international broadcast station may transmit the program of a AM broadcast station or network system: Provided, That the conditions in paragraph (b) of this section as to any commercial continuities are observed and when station identifications are made, only the call letter designation of the international station is given and its assigned frequency: And provided further, That in the case of chain broadcasting the program is not carried simultaneously by another international station (except another station owned by the same licensee operated on a frequency in a different group to obtain continuity of signal service), the signals from which are directed to the same area. (See section 3(p) of the Communications Act of 1934 for the definition of “chain broadcasting.”)

Except as provided in § 73.220 of this chapter, all of the frequencies listed in § 73.201 of this chapter are available for LPFM stations.
§ 73.807   Minimum distance separation between stations.
Minimum separation requirements for LPFM stations are listed in the following paragraphs. Except as noted below, an LPFM station will not be authorized unless the co-channel, and first- and second-adjacent channel separations are met. An LPFM station need not satisfy the third-adjacent channel separations listed in paragraphs (a) through (c) of this section in order to be authorized. The third-adjacent channel separations are included for use in determining for purposes of § 73.810 which third-adjacent channel interference regime applies to an LPFM station. Minimum distances for co-channel and first-adjacent channel are separated into two columns. The left-hand column lists the required minimum separation to protect other stations and the right-hand column lists (for informational purposes only) the minimum distance necessary for the LPFM station to receive no interference from other stations assumed to be operating at the maximum permitted facilities for the station class. For second-adjacent channel, the required minimum distance separation is sufficient to avoid interference received from other stations.
(a)(1) An LPFM station will not be authorized initially unless the minimum distance separations in the following table are met with respect to authorized FM stations, applications for new and existing FM stations filed prior to the release of the public notice announcing an LPFM window period, authorized LPFM stations, LPFM station applications that were timely-filed within a previous window, and vacant FM allotments. LPFM modification applications must either meet the distance separations in the following table or, if short-spaced, not lessen the spacing to subsequently authorized stations.
(2) LPFM stations must satisfy the second-adjacent channel minimum distance separation requirements of paragraph (a)(1) of this section with respect to any third-adjacent channel FM station that, as of September 20, 2000, broadcasts a radio reading service via a subcarrier frequency.
(b) In addition to meeting or exceeding the minimum separations in paragraph (a) of this section, new LPFM stations will not be autorized in Puerto Rico or the Virgin Islands unless the minimum distance separations in the following tables are met with respect to authorized or proposed FM stations:
Minimum distance separations towards “grandfathered” superpowered Reserved Band stations are as specified. Full service FM stations operating within the reserved band (Channels 201-220) with facilities in excess of those permitted in § 73.211(b)(1) or (b)(3) shall be protected by LPFM stations in accordance with the minimum distance separations for the nearest class as determined under § 73.211. For example, a Class B1 station operating with facilities that result in a 60 dBu contour that exceeds 39 kilometers but is less than 52 kilometers would be protected by the Class B minimum distance separations. Class D stations with 60 dBu contours that exceed 5 kilometers will be protected by the Class A minimum distance separations. Class B stations with 60 dBu contours that exceed 52 kilometers will be protected as Class C1 or Class C stations depending upon the distance to the 60 dBu contour. No stations will be protected beyond Class C separations.
(c) In addition to meeting the separations specified in paragraphs (a) and (b), LPFM applications must meet the minimum separation requirements in the following table with respect to authorized FM translator stations, cutoff FM translator applications, and FM translator applications filed prior to the release of the Public Notice announcing the LPFM window period.
(d) Existing LPFM stations which do not meet the separations in paragraphs (a) through (c) of this section may be relocated provided that the separation to any short-spaced station is not reduced.
(e)(1) Waiver of the second-adjacent channel separations. The Commission will entertain requests to waive the second-adjacent channel separations in paragraphs (a) through (c) of this section on a case-by-case basis. In each case, the LPFM station must establish, using methods of predicting interference taking into account all relevant factors, including terrain-sensitive propagation models, that its proposed operations will not result in interference to any authorized radio service. The LPFM station may do so by demonstrating that no actual interference will occur due to intervening terrain or lack of population. The LPFM station may use an undesired/desired signal strength ratio methodology to define areas of potential interference.
(2) Interference. (i) Upon receipt of a complaint of interference from an LPFM station operating pursuant to a waiver granted under paragraph (e)(1) of this section, the Commission shall notify the identified LPFM station by telephone or other electronic communication within one business day.
(ii) An LPFM station that receives a waiver under paragraph (e)(1) of this section shall suspend operation immediately upon notification by the Commission that it is causing interference to the reception of an existing or modified full-service FM station without regard to the location of the station receiving interference. The LPFM station shall not resume operation until such interference has been eliminated or it can demonstrate to the Commission that the interference was not due to emissions from the LPFM station. Short test transmissions may be made during the period of suspended operation to check the efficacy of remedial measures.
(f) Commercial and noncommercial educational stations authorized under subparts B and C of this part, as well as new or modified commercial FM allotments, are not required to adhere to the separations specified in this rule section, even where new or increased interference would be created.
(g) International considerations within the border zones. (1) Within 320 km of the Canadian border, LPFM stations must meet the following minimum separations with respect to any Canadian stations:
(2) Within 320 km of the Mexican border, LPFM stations must meet the following separations with respect to any Mexican stations:
(3) The Commission will notify the International Telecommunications Union (ITU) of any LPFM authorizations in the US Virgin Islands. Any authorization issued for a US Virgin Islands LPFM station will include a condition that permits the Commission to modify, suspend or terminate without right to a hearing if found by the Commission to be necessary to conform to any international regulations or agreements.
(4) The Commission will initiate international coordination of a LPFM proposal even where the above Canadian and Mexican spacing tables are met, if it appears that such coordination is necessary to maintain compliance with international agreements.
(5)(i) LPFM stations located within 125 kilometers of the Mexican border are limited to 50 watts (0.05 kW) ERP, a 60 dBu service contour of 8.7 kilometers and a 34 dBu interfering contour of 32 kilometers in the direction of the Mexican border. LPFM stations may operate up to 100 watts in all other directions.
(ii) LPFM stations located between 125 kilometers and 320 kilometers from the Mexican border may operate in excess of 50 watts, up to a maximum ERP of 100 watts. However, in no event shall the location of the 60 dBu contour lie within 116.3 kilometers of the Mexican border.
(iii) Applications for LPFM stations within 320 kilometers of the Canadian border may employ an ERP of up to a maximum of 100 watts. The distance to the 34 dBu interfering contour may not exceed 60 kilometers in any direction.
§ 73.808   Distance computations.
For the purposes of determining compliance with any LPFM distance requirements, distances shall be calculated in accordance with § 73.208(c) of this part.
§ 73.809   Interference protection to full service FM stations.
(a) If a full service commercial or NCE FM facility application is filed subsequent to the filing of an LPFM station facility application, such full service station is protected against any condition of interference to the direct reception of its signal that is caused by such LPFM station operating on the same channel or first-adjacent channel provided that the interference is predicted to occur and actually occurs within:
(1) The 3.16 mV/m (70 dBu) contour of such full service station;
(2) The community of license of such full service station; or
(3) Any area of the community of license of such full service station that is predicted to receive at least a 1 mV/m (60 dBu) signal. Predicted interference shall be calculated in accordance with the ratios set forth in § 73.215 paragraphs (a)(1) and (a)(2). Intermediate frequency (IF) channel interference overlap will be determined based upon overlap of the 91 dBu F(50,50) contours of the FM and LPFM stations. Actual interference will be considered to occur whenever reception of a regularly used signal is impaired by the signal radiated by the LPFM station.
(b) An LPFM station will be provided an opportunity to demonstrate in connection with the processing of the commercial or NCE FM application that interference as described in paragraph (a) of this section is unlikely. If the LPFM station fails to so demonstrate, it will be required to cease operations upon the commencement of program tests by the commercial or NCE FM station.
(c) Complaints of actual interference by an LPFM station subject to paragraphs (a) and (b) of this section must be served on the LPFM licensee and the Federal Communications Commission, attention Audio Services Division. The LPFM station must suspend operations within twenty-four hours of the receipt of such complaint unless the interference has been resolved to the satisfaction of the complainant on the basis of suitable techniques. An LPFM station may only resume operations at the direction of the Federal Communications Commission. If the Commission determines that the complainant has refused to permit the LPFM station to apply remedial techniques that demonstrably will eliminate the interference without impairment of the original reception, the licensee of the LPFM station is absolved of further responsibility for the complaint.
(d) It shall be the responsibility of the licensee of an LPFM station to correct any condition of interference that results from the radiation of radio frequency energy outside its assigned channel. Upon notice by the FCC to the station licensee or operator that such interference is caused by spurious emissions of the station, operation of the station shall be immediately suspended and not resumed until the interference has been eliminated. However, short test transmissions may be made during the period of suspended operation to check the efficacy of remedial measures.
(e) In each instance where suspension of operation is required, the licensee shall submit a full report to the FCC in Washington, DC, after operation is resumed, containing details of the nature of the interference, the source of the interfering signals, and the remedial steps taken to eliminate the interference.
§ 73.810   Third adjacent channel interference.
(a) LPFM Stations Licensed at Locations That Do Not Satisfy Third-Adjacent Channel Minimum Distance Separations. An LPFM station licensed at a location that does not satisfy the third-adjacent channel minimum distance separations set forth in § 73.807 is subject to the following provisions:
(1) Such an LPFM station will not be permitted to continue to operate if it causes any actual third-adjacent channel interference to:
(i) The transmission of any authorized broadcast station; or
(ii) The reception of the input signal of any TV translator, TV booster, FM translator or FM booster station; or
(iii) The direct reception by the public of the off-the-air signals of any full-service station or previously authorized secondary station. Interference will be considered to occur whenever reception of a regularly used signal on a third-adjacent channel is impaired by the signals radiated by the LPFM station, regardless of the quality of such reception, the strength of the signal so used, or the channel on which the protected signal is transmitted.
(2) If third-adjacent channel interference cannot be properly eliminated by the application of suitable techniques, operation of the offending LPFM station shall be suspended and shall not be resumed until the interference has been eliminated. Short test transmissions may be made during the period of suspended operation to check the efficacy of remedial measures. If a complainant refuses to permit the licensee of the offending LPFM station to apply remedial techniques which demonstrably will eliminate the third-adjacent channel interference without impairment to the original reception, the licensee is absolved of further responsibility for that complaint.
(3) Upon notice by the Commission to the licensee that such third-adjacent channel interference is being caused, the operation of the LPFM station shall be suspended within three minutes and shall not be resumed until the interference has been eliminated or it can be demonstrated that the interference is not due to spurious emissions by the LPFM station; provided, however, that short test transmissions may be made during the period of suspended operation to check the efficacy of remedial measures.
(b) LPFM stations licensed at locations that satisfy third-adjacent channel minimum distance separations. An LPFM station licensed at a location that satisfies the third-adjacent channel minimum distance separations set forth in § 73.807 is subject to the following provisions:
(1) Interference complaints and remediation. (i) Such an LPFM station is required to provide copies of all complaints alleging that its signal is causing third-adjacent channel interference to or impairing the reception of the signal of a full power FM, FM translator or FM booster station to such affected station and to the Commission.
(ii) A full power FM, FM translator or FM booster station shall review all complaints it receives, either directly or indirectly, from listeners regarding alleged third-adjacent channel interference caused by the operations of such an LPFM station. Such full power FM, FM translator or FM booster station shall also identify those that qualify as bona fide complaints under this section and promptly provide such LPFM station with copies of all bona fide complaints. A bona fide complaint:
(A) Must include current contact information for the complainant;
(B) Must state the nature and location of the alleged third-adjacent channel interference and must specify the call signs of the LPFM station and affected full power FM, FM translator or FM booster station, and the type of receiver involved; and
(C) Must be received by either the LPFM station or the affected full power FM, FM translator or FM booster station within one year of the date on which the LPFM station commenced broadcasts with its currently authorized facilities.
(iii) The Commission will accept bona fide complaints and will notify the licensee of the LPFM station allegedly causing third-adjacent channel interference to the signal of a full power FM, FM translator or FM booster station of the existence of the alleged interference within 7 calendar days of the Commission's receipt of such complaint.
(iv) Such an LPFM station will be given a reasonable opportunity to resolve all complaints of third-adjacent channel interference within the protected contour of the affected full power FM, FM translator or FM booster station. A complaint will be considered resolved where the complainant does not reasonably cooperate with an LPFM station's remedial efforts. Such an LPFM station also is encouraged to address all other complaints of third-adjacent channel interference, including complaints based on interference to a full power FM, FM translator or FM booster station by the transmitter site of the LPFM station at any distance from the full power, FM translator or FM booster station.
(v) In the event that the number of unresolved complaints of third-adjacent channel interference within the protected contour of the affected full power FM, FM translator or FM booster station plus the number of complaints for which the source of third-adjacent channel interference remains in dispute equals at least one percent of the households within one kilometer of the LPFM transmitter site or thirty households, whichever is less, the LPFM and affected stations must cooperate in an “on-off” test to determine whether the third-adjacent channel interference is traceable to the LPFM station.
(vi) If the number of unresolved and disputed complaints of third-adjacent channel interference within the protected contour of the affected full power, FM translator or FM booster station exceeds the numeric threshold specified in paragraph (b)(1)(v) of this section following an “on-off” test, the affected station may request that the Commission initiate a proceeding to consider whether the LPFM station license should be modified or cancelled, which will be completed by the Commission within 90 days. Parties may seek extensions of the 90-day deadline consistent with Commission rules.
(vii) An LPFM station may stay any procedures initiated pursuant to paragraph (b)(1)(vi) of this section by voluntarily ceasing operations and filing an application for facility modification within twenty days of the commencement of such procedures.
(2) Periodic announcements. (i) For a period of one year from the date of licensing of a new LPFM station that is constructed on a third-adjacent channel and satisfies the third-adjacent channel minimum distance separations set forth in § 73.807, such LPFM station shall broadcast periodic announcements. The announcements shall, at a minimum, alert listeners of the potentially affected third-adjacent channel station of the potential for interference, instruct listeners to contact the LPFM station to report any interference, and provide contact information for the LPFM station. The announcements shall be made in the primary language(s) of both the new LPFM station and the potentially affected third-adjacent channel station(s). Sample announcement language follows:
On (date of license grant), the Federal Communications Commission granted (LPFM station's call letters) a license to operate. (LPFM station's call letters) may cause interference to the operations of (third-adjacent channel station's call letters) and (other third-adjacent channel stations' call letters). If you are normally a listener of (third-adjacent channel station's call letters) or (other third-adjacent channel station's call letters) and are having difficulty receiving (third-adjacent channel station call letters) or (other third-adjacent channel station's call letters), please contact (LPFM station's call letters) by mail at (mailing address) or by telephone at (telephone number) to report this interference.
(ii) During the first thirty days after licensing of a new LPFM station that is constructed on a third-adjacent channel and satisfies the third-adjacent channel minimum distance separations set forth in Section 73.807, the LPFM station must broadcast the announcements specified in paragraph (b)(2)(i) of this section at least twice daily. The first daily announcement must be made between the hours of 7 a.m. and 9 a.m., or 4 p.m. and 6 p.m. The LPFM station must vary the time slot in which it airs this announcement. For stations that do not operate at these times, the announcements shall be made during the first two hours of broadcast operations each day. The second daily announcement must be made outside of the 7 a.m. to 9 a.m. and 4 p.m. to 6 p.m. time slots. The LPFM station must vary the times of day in which it broadcasts this second daily announcement in order to ensure that the announcements air during all parts of its broadcast day. For stations that do not operate at these times, the announcements shall be made during the first two hours of broadcast operations each day. For the remainder of the one year period, the LPFM station must broadcast the announcements at least twice per week. The announcements must be broadcast between the hours of 7 a.m. and midnight. For stations that do not operate at these times, the announcements shall be made during the first two hours of broadcast operations each day.
(iii) Any new LPFM station that is constructed on a third-adjacent channel and satisfies the minimum distance separations set forth in § 73.807 must:
(A) notify the Audio Division, Media Bureau, and all affected stations on third-adjacent channels of an interference complaint. The notification must be made electronically within 48 hours after the receipt of an interference complaint by the LPFM station; and
(B) cooperate in addressing any third-adjacent channel interference.
§ 73.811   LPFM power and antenna height requirements.
(a) Maximum facilities. LPFM stations will be authorized to operate with maximum facilities of 100 watts ERP at 30 meters HAAT. An LPFM station with a HAAT that exceeds 30 meters will not be permitted to operate with an ERP greater than that which would result in a 60 dBu contour of 5.6 kilometers. In no event will an ERP less than one watt be authorized. No facility will be authorized in excess of one watt ERP at 450 meters HAAT.
(b) Minimum facilities. LPFM stations may not operate with facilities less than 50 watts ERP at 30 meters HAAT or the equivalent necessary to produce a 60 dBu contour that extends at least 4.7 kilometers.
§ 73.812   Rounding of power and antenna heights.
(a) Effective radiated power (ERP) will be rounded to the nearest watt on LPFM authorizations.
(b) Antenna radiation center, antenna height above average terrain (HAAT), and antenna supporting structure height will all be rounded to the nearest meter on LPFM authorizations.
§ 73.813   Determination of antenna height above average terrain (HAAT).
HAAT determinations for LPFM stations will be made in accordance with the procedure detailed in § 73.313(d) of this part.
§ 73.816   Antennas.
(a) Permittees and licensees may employ nondirectional antennas with horizontal only polarization, vertical only polarization, circular polarization or elliptical polarization.
(b) Permittees and licensees may employ directional antennas in the LPFM service, in accordance with paragraph (d) of this section.
(c) [Reserved]
(d)(1) Composite antennas and antenna arrays may be used where the total ERP does not exceed the maximum determined in accordance with § 73.811(a).
(2) Either horizontal, vertical, circular, or elliptical polarization may be used provided that the supplemental vertically polarized ERP required for circular or elliptical polarization does not exceed the ERP otherwise authorized. Either clockwise or counterclockwise rotation may be used. Separate transmitting antennas are permitted if both horizontal and vertical polarization is to be provided.
(3) An application that specifies the use of a directional antenna must provide the information identified in § 73.316(c) except that such information shall not be required of:
(i) Public safety and transportation permittees and licensees eligible pursuant to § 73.853(a)(2) using directional antennas in connection with operation of Travelers' Information Service stations;
(ii) LPFM permittees and licensees proposing a waiver of the second-adjacent channel spacing requirements of § 73.807 for the sole purpose of justifying such a waiver; and
(iii) LPFM permittees and licensees using directional antennas solely for the purpose of meeting the international border zone distance requirements of § 73.807(g).
§ 73.825   Protection to reception of TV channel 6.
The following spacing requirements will apply to LPFM applications on Channels 201 through 220 unless the application is accompanied by a written agreement between the LPFM applicant and each affected TV Channel 6 broadcast station concurring with the proposed LPFM facilities.
(a) LPFM stations will be authorized on Channels 201 through 220 only if the pertinent minimum separation distances in the following table are met with respect to all full power TV Channel 6 stations.
(b) LPFM stations will be authorized on Channels 201 through 220 only if the pertinent minimum separation distances in the following table are met with respect to all low power TV, TV translator, and Class A TV stations authorized on TV Channel 6.
§ 73.827   Interference to the input signals of FM translator or FM booster stations.
(a) Interference to the direct reception of the input signal of an FM translator station. This subsection applies when an LPFM application proposes to operate near an FM translator station, the FM translator station is receiving its input signal off-air (either directly from the primary station or from a translator station) and the LPFM application proposes to operate on a third-adjacent channel to the station delivering an input signal to the translator station. In these circumstances, the LPFM station will not be authorized unless it is located at least 2 km from the FM translator station. In addition, in cases where an LPFM station is located within ±30 degrees of the azimuth between the FM translator station and its input signal, the LPFM station will not be authorized unless it is located at least 10 kilometers from the FM translator station. The provisions of this subsection will not apply if the LPFM applicant:
(1) Demonstrates that no actual interference will occur due to an undesired (LPFM) to desired (station delivering signal to translator station) ratio below 34 dB at such translator station's receive antenna.
(2) Complies with the minimum LPFM/FM translator distance separation calculated in accordance with the following formula: d u = 133.5 antilog [(P eu + G ru − G rd − E d )/20], where d u = the minimum allowed separation in km, P eu = LPFM ERP in dBW, G ru = gain (dBd) of the FM translator receive antenna in the direction of the LPFM site, G rd = gain (dBd) of the FM translator receive antenna in the direction of the primary station site, E d = predicted field strength (dBu) of the primary station at the translator site, or
(3) Reaches an agreement with the licensee of the FM translator regarding an alternative technical solution.
LPFM applicants may assume that an FM translator station's receive and transmit antennas are collocated.
(b) An authorized LPFM station will not be permitted to continue to operate if an FM translator or FM booster station demonstrates that the LPFM station is causing actual interference to the FM translator or FM booster station's input signal, provided that the same input signal was in use or proposed in an application filed with the Commission prior to the release of the public notice announcing the dates for an LPFM application filing window and has been continuously in use or proposed since that time.
(c) Complaints of actual interference by an LPFM station subject to paragraph (b) of this section must be served on the LPFM licensee and the Federal Communications Commission, Attention: Audio Division, Media Bureau. The LPFM station must suspend operations upon the receipt of such complaint unless the interference has been resolved to the satisfaction of the complainant on the basis of suitable techniques. Short test transmissions may be made during the period of suspended operations to check the efficacy of remedial measures. An LPFM station may only resume full operation at the direction of the Federal Communications Commission. If the Commission determines that the complainant has refused to permit the LPFM station to apply remedial techniques that demonstrably will eliminate the interference without impairment of the original reception, the licensee of the LPFM station is absolved of further responsibility for the complaint.
§ 73.840   Operating power and mode tolerances.
The transmitter power output (TPO) of an LPFM station must be determined by the procedures set forth in § 73.267 of this part. The operating TPO of an LPFM station with an authorized TPO of more than ten watts must be maintained as near as practicable to its authorized TPO and may not be less than 90% of the minimum TPO nor greater than 105% of the maximum authorized TPO. An LPFM station with an authorized TPO of ten watts or less may operate with less than the authorized power, but not more than 105% of the authorized power.
§ 73.845   Transmission system operation.
Each LPFM licensee is responsible for maintaining and operating its broadcast station in a manner that complies with the technical rules set forth elsewhere in this part and in accordance with the terms of the station authorization. In the event that an LPFM station is operating in a manner that is not in compliance with the technical rules set forth elsewhere in this part or the terms of the station authorization, broadcast operation must be terminated within three hours.
§ 73.850   Operating schedule.
(a) All LPFM stations will be licensed for unlimited time operation, except those stations operating under a time sharing agreement pursuant to § 73.872.
(b) All LPFM stations are required to operate at least 36 hours per week, consisting of at least 5 hours of operation per day on at least 6 days of the week; however, stations licensed to educational institutions are not required to operate on Saturday or Sunday or to observe the minimum operating requirements during those days designated on the official school calendar as vacation or recess periods.
(c) All LPFM stations, including those meeting the requirements of paragraph (b) of this section, but which do not operate 12 hours per day each day of the year, will be required to share use of the frequency upon the grant of an appropriate application proposing such share time arrangement. Such applications must set forth the intent to share time and must be filed in the same manner as are applications for new stations. Such applications may be filed at any time after an LPFM station completes its third year of licensed operations. In cases where the licensee and the prospective licensee are unable to agree on time sharing, action on the application will be taken only in connection with a renewal application for the existing station filed on or after June 1, 2019. In order to be considered for this purpose, an application to share time must be filed no later than the deadline for filing petitions to deny the renewal application of the existing licensee.
(1) The licensee and the prospective licensee(s) shall endeavor to reach an agreement for a definite schedule of periods of time to be used by each. Such agreement must be in writing and must set forth which licensee is to operate on each of the hours of the day throughout the year. Such agreement must not include simultaneous operation of the stations. Each licensee must file the same in triplicate with each application to the Commission for initial construction permit or renewal of license. Such written agreements shall become part of the terms of each station's license.
(2) The Commission desires to facilitate the reaching of agreements on time sharing. However, if the licensees of stations authorized to share time are unable to agree on a division of time, the prospective licensee(s) must submit a statement with the Commission to that effect filed with the application(s) proposing time sharing.
(3) After receipt of the type of application(s) described in paragraph (c)(2) of this section, the Commission will process such application(s) pursuant to §§ 73.3561 through 73.3568 of this Part. If any such application is not dismissed pursuant to those provisions, the Commission will issue a notice to the parties proposing a time-sharing arrangement and a grant of the time-sharing application(s). The licensee may protest the proposed action, the prospective licensee(s) may oppose the protest and/or the proposed action, and the licensee may reply within the time limits delineated in the notice. All such pleadings must satisfy the requirements of Section 309(d) of the Act. Based on those pleadings and the requirements of Section 309 of the Act, the Commission will then act on the time-sharing application(s) and the licensee's renewal application.
(4) A departure from the regular schedule set forth in a time-sharing agreement will be permitted only in cases where a written agreement to that effect is reduced to writing, is signed by the licensees of the stations affected thereby, and is filed in triplicate by each licensee with the Commission, Attention: Audio Division, Media Bureau, prior to the time of the proposed change. If time is of the essence, the actual departure in operating schedule may precede the actual filing of the written agreement, provided that appropriate notice is sent to the Commission in Washington, DC, Attention: Audio Division, Media Bureau.
(d) In the event that causes beyond the control of a permittee or licensee make it impossible to adhere to the operating schedule in paragraph (b) of this section or to continue operating, the station may limit or discontinue operation for a period not exceeding 30 days without further authority from the Commission provided that notification is sent to the Commission in Washington, DC, Attention: Audio Division, Media Bureau, no later than the 10th day of limited or discontinued operation. During such period, the permittee shall continue to adhere to the requirements of the station license pertaining to lighting of antenna structures. In the event normal operation is restored prior to the expiration of the 30 day period, the permittee or licensee will notify the FCC, Attention: Audio Division, of the date that normal operations resumed. If causes beyond the control of the permittee or licensee make it impossible to comply within the allowed period, Special Temporary Authority (see § 73.1635) must be requested to remain silent for such additional time as deemed necessary not to exceed, in total, 12 consecutive months (see § 73.873(b)).
§ 73.853   Licensing requirements and service.
(a) An LPFM station may be licensed only to:
(1) Nonprofit educational organizations and upon a showing that the proposed station will be used for the advancement of an educational program; and

No application for an LPFM station may be granted unless the applicant certifies, under penalty of perjury, that neither the applicant, nor any party to the application, has engaged in any manner, including individually or with persons, groups, organizations, or other entities, in the unlicensed operation of any station in violation of Section 301 of the Communications Act of 1934, as amended, 47 U.S.C. 301. If an application is dismissed pursuant to this section, the applicant is precluded from seeking nunc pro tunc reinstatement of the application and/or changing its directors to resolve the basic qualification issues.
§ 73.855   Ownership limits.
(a) No authorization for an LPFM station shall be granted to any party if the grant of that authorization will result in any such party holding an attributable interest in two or more LPFM stations.
(b) Notwithstanding the general prohibition set forth in paragraph (a) of this section, Tribal Applicants, as defined in § 73.853(c), may hold an attributable interest in up to two LPFM stations.
(c) Notwithstanding the general prohibition set forth in paragraph (a) of this section, not-for-profit organizations and governmental entities with a public safety purpose may be granted multiple licenses if:
(1) One of the multiple applications is submitted as a priority application; and
(2) The remaining non-priority applications do not face a mutually exclusive challenge.
§ 73.858   Attribution of LPFM station interests.
Ownership and other interests in LPFM station permittees and licensees will be attributed to their holders and deemed cognizable for the purposes of §§ 73.855 and 73.860, in accordance with the provisions of § 73.3555, subject to the following exceptions:
(a) A director of an entity that holds an LPFM license will not have such interest treated as attributable if such director also holds an attributable interest in a broadcast licensee or other media entity but recuses himself or herself from any matters affecting the LPFM station.
(b) A local chapter of a national or other large organization shall not have the attributable interests of the national organization attributed to it provided that the local chapter is separately incorporated and has a distinct local presence and mission.
(c) A parent or subsidiary of a LPFM licensee or permittee that is a non-stock corporation will be treated as having an attributable interest in such corporation. The officers, directors, and members of a non-stock corporation's governing body and of any parent or subsidiary entity will have such positional interests attributed to them.
§ 73.860   Cross-ownership.
(a) Except as provided in paragraphs (b), (c) and (d) of this section, no license shall be granted to any party if the grant of such authorization will result in the same party holding an attributable interest in any other non-LPFM broadcast station, including any FM translator or low power television station, or any other media subject to our broadcast ownership restrictions.
(b) A party that is not a Tribal Applicant, as defined in § 73.853(c), may hold attributable interests in one LPFM station and no more than two FM translator stations, two FM booster stations, or one FM translator station and one FM booster station provided that the following requirements are met:
(1) The 60 dBu contour of the LPFM station overlaps the 60 dBu contour of the commonly-owned FM translator station(s) and entirely encompasses the 60 dBu service contour of the FM booster station(s);
(2) The FM translator and/or booster station(s), at all times, synchronously rebroadcasts the primary analog signal of the commonly-owned LPFM station or, if the commonly-owned LPFM station operates in hybrid mode, synchronously rebroadcasts the digital HD-1 version of the LPFM station's signal;
(3) The FM translator station receives the signal of the commonly-owned LPFM station over-the-air and directly from the commonly-owned LPFM station itself. The FM booster station receives the signal of the commonly-owned LPFM station by any means authorized in § 74.1231(i) of this chapter;
(4) The transmitting antenna of the FM translator and/or booster station(s) is located within 16.1 kilometers (10 miles) for LPFM stations located in the top 50 urban markets and 32.1 kilometers (20 miles) for LPFM stations outside the top 50 urban markets of either the transmitter site of the commonly-owned LPFM station or the reference coordinates for that station's community of license; and
(5) Booster stations commonly owned by LPFM stations may conduct transmissions independent of those broadcast by the primary LPFM station for a period not to exceed three minutes of each broadcast hour. This is a strict hourly limit that may not be exceeded by aggregating unused minutes of program origination. Any such booster stations must comply with the rules concerning the Emergency Alert System set out in part 11 of this chapter.
(c) A party that is a Tribal Applicant, as defined in § 73.853(c), may hold attributable interests in no more than two LPFM stations and four FM translator stations provided that the requirements set forth in paragraph (b) of this section are met.
(d) Unless such interest is permissible under paragraphs (b) or (c) of this section, a party with an attributable interest in a broadcast radio station must divest such interest prior to the commencement of operations of an LPFM station in which the party also holds an interest. However, a party need not divest such an attributable interest if the party is a college or university that can certify that the existing broadcast radio station is not student run. This exception applies only to parties that:
(1) Are accredited educational institutions;
(2) Own an attributable interest in non-student run broadcast stations; and
(3) Apply for an authorization for an LPFM station that will be managed and operated on a day-to-day basis by students of the accredited educational institution.
(e) No LPFM licensee may enter into an operating agreement of any type, including a time brokerage or management agreement, with either a full power broadcast station or another LPFM station.
§ 73.865   Assignment and transfer of LPFM permits and licenses.
(a) Assignment/transfer. No party may assign or transfer an LPFM permit or license if:
(1) Consideration promised or received exceeds the legitimate and prudent expenses of the assignor or transferor. For purposes of this section, legitimate and prudent expenses are those expenses reasonably incurred by the assignor or transferor in obtaining and constructing the station (e.g., expenses in preparing an application, in obtaining and installing broadcast equipment to be assigned or transferred, etc.). Costs incurred in operating the station are not recoverable (e.g., rent, salaries, utilities, music licensing fees, etc.);
(2) The assignee or transferee is incapable of satisfying all eligibility criteria that apply to a LPFM licensee; or
(3) For a period of time commencing with the grant of any construction permit awarded based on the comparative point system, § 73.872, and continuing until the station has achieved at least four years of on-air operations:
(i)(A) The assignee or transferee cannot meet or exceed the points awarded to the initial applicant; or
(B) Where the original LPFM construction permit was issued based on a point system tie-breaker, the assignee or transferee does not have a “locally established date,” as defined in § 73.853(b), that is the same as, or earlier than, the date of the most recently established local applicant in the tied mutually exclusive (MX) group.
(ii) Any successive applicants proposing to assign or transfer the construction permit or license prior to the end of the aforementioned period will be required to make the same demonstrations. This restriction does not apply to construction permits that are awarded to non-mutually exclusive applicants or through settlement.
(b) Name change. A change in the name of an LPFM permittee or licensee where no change in ownership or control is involved may be accomplished by written notification by the permittee or licensee to the Commission.
(c) Holding period. A construction permit cannot be assigned or transferred for 18 months from the date of issue.
(d) Board changes. Notwithstanding the other provisions in this section, transfers of control involving a sudden or gradual change of more than 50 percent of an LPFM's governing board are not prohibited, provided that the mission of the entity remains the same and the requirements of paragraph (a) of this section are satisfied. Sudden majority board changes shall be submitted as a pro forma ownership change within 30 days of the change or final event that caused the LPFM permittee or licensee to exceed the 50 percent threshold.
§ 73.870   Processing of LPFM broadcast station applications.
(a) A minor change for an LPFM station authorized under this subpart is limited to transmitter site relocations not exceeding 11.2 kilometers or where the 60 dBu contour of the authorized facility overlaps the 60 dBu contour of the proposed facility. These distance limitations do not apply to amendments or applications proposing transmitter site relocation to a common location filed by applicants that are parties to a voluntary time-sharing agreement with regard to their stations pursuant to § 73.872(c) and (e). These distance limitations also do not apply to an amendment or application proposing transmitter site relocation to a common location or a location very close to another station operating on a third-adjacent channel in order to remediate interference to the other station; provided, however, that the proposed relocation is consistent with all localism certifications made by the applicant in its original application for the LPFM station. Minor changes of LPFM stations may include:
(1) Changes in frequency to adjacent or IF frequencies (± 1, 2, 3, 53 or 54 channels) or, upon a technical showing of reduced interference, to any frequency; and
(2) Amendments to time-sharing agreements, including universal agreements that supersede involuntary arrangements.
(b) The Commission will specify by Public Notice a window filing period for applications for new LPFM stations and major modifications in the facilities of authorized LPFM stations. LPFM applications for new facilities and for major modifications in authorized LPFM stations will be accepted only during the appropriate window. Applications submitted prior to the window opening date identified in the Public Notice will be returned as premature. Applications submitted after the deadline will be dismissed with prejudice as untimely.
(c) Applications subject to paragraph (b) of this section that fail to meet the § 73.807 minimum distance separations with respect to all applications and facilities in existence as the date of the pertinent public notice in paragraph (b) of this section other than to LPFM station facilities proposed in applications filed in the same window, will be dismissed without any opportunity to amend such applications.
(d) Following the close of the window, the Commission will issue a Public Notice of acceptance for filing of applications submitted pursuant to paragraph (b) of this section that meet technical and legal requirements and that are not in conflict with any other application filed during the window. Following the close of the window, the Commission also will issue a Public Notice of the acceptance for filing of all applications tentatively selected pursuant to the procedures for mutually exclusive LPFM applications set forth at § 73.872. Petitions to deny such applications may be filed within 30 days of such public notice and in accordance with the procedures set forth at § 73.3584. A copy of any petition to deny must be served on the applicant.
(e) Minor change LPFM applications may be filed at any time, unless restricted by the staff, and generally, will be processed in the order in which they are tendered. Such applications must meet all technical and legal requirements applicable to new LPFM station applications.
(f) New entrants seeking to apply for unused or unwanted time on a time-sharing frequency will only be accepted during an open filing window, specified pursuant to paragraph (b) of this section.
§ 73.871   Amendment of LPFM broadcast station applications.
(a) New and major change applications may be amended without limitation during the pertinent filing window.
(b) Amendments that would improve the comparative position of new and major change applications will not be accepted after the close of the pertinent filing window.
(c) Only minor amendments to new and major change applications will be accepted after the close of the pertinent filing window. Subject to the provisions of this section, such amendments may be filed as a matter of right by the date specified in the FCC's Public Notice announcing the acceptance of such applications. For the purposes of this section, minor amendments are limited to:
(1) Site relocations of 11.2 kilometers or less;
(2) Site relocations that involve overlap between the 60 dBu service contours of the currently authorized and proposed facilities;
(3) Changes in ownership where the original party or parties to an application either:
(i) Retain more than a 50 percent ownership interest in the application as originally filed;
(ii) Retain an ownership interest of 50 percent or less as the result of governing board changes in a nonstock or membership applicant that occur over a period of six months or more; or
(iii) Retain an ownership interest of 50 percent or less as the result of governing board changes in a nonstock or membership applicant that occur over a period of less than six months and there is no evidence of a takeover concern or a significant effect on such organization's mission. All changes in a governmental applicant are considered minor;
(4) Universal voluntary time-sharing agreements to apportion vacant time among the licensees;
(5) Other changes in general and/or legal information;
(6) Filings proposing transmitter site relocation to a common location submitted by applications that are parties to a voluntary time-sharing agreement with regard to their stations pursuant to § 73.872 (c) and (e); and
(7) Filings proposing transmitter site relocation to a common location or a location very close to another station operating on a third-adjacent channel in order to remediate interference to the other station.
(d) Unauthorized or untimely amendments are subject to return by the FCC's staff without consideration.
§ 73.872   Selection procedure for mutually exclusive LPFM applications.
(a) Following the close of each window for new LPFM stations and for modifications in the facilities of authorized LPFM stations, the Commission will issue a public notice identifying all groups of mutually exclusive applications. Such applications will be awarded points to determine the tentative selectee. Unless resolved by settlement pursuant to paragraph (e) of this section, the tentative selectee will be the applicant within each group with the highest point total under the procedure set forth in this section, except as provided in paragraphs (c) and (d) of this section .
(b) Each mutually exclusive application will be awarded one point for each of the following criteria, based on certifications that the qualifying conditions are met and submission of any required documentation:
(1) Established community presence. An applicant must, for a period of at least two years prior to application and at all times thereafter, have qualified as local pursuant to § 73.853(b). Applicants claiming a point for this criterion must submit any documentation specified in FCC Form 318 at the time of filing their applications.
(2) Local program origination. The applicant must pledge to originate locally at least eight hours of programming per day. For purposes of this criterion, local origination is the production of programming by the licensee, within ten miles of the coordinates of the proposed transmitting antenna. Local origination includes licensee produced call-in shows, music selected and played by a disc jockey present on site, broadcasts of events at local schools, and broadcasts of musical performances at a local studio or festival, whether recorded or live. Local origination does not include the broadcast of repetitive or automated programs or time-shifted recordings of non-local programming whatever its source. In addition, local origination does not include a local program that has been broadcast twice, even if the licensee broadcasts the program on a different day or makes small variations in the program thereafter.
(3) Main studio. The applicant must pledge to maintain a publicly accessible main studio that has local program origination capability, is reachable by telephone, is staffed at least 20 hours per week between 7 a.m. and 10 p.m., and is located within 16.1 km (10 miles) of the proposed site for the transmitting antenna for applicants in the top 50 urban markets and 32.1 km (20 miles) for applicants outside the top 50 urban markets. Applicants claiming a point under this criterion must specify the proposed address and telephone number for the proposed main studio in FCC Form 318 at the time of filing their applications.
(4) Local program origination and main studio. The applicant must make both the local program origination and main studio pledges set forth in paragraphs (b)(2) and (3) of this section.
(5) Diversity of ownership. An applicant must hold no attributable interests in any other broadcast station.
(6) Tribal Applicants serving Tribal Lands. The applicant must be a Tribal Applicant, as defined in § 73.853(c), and the proposed site for the transmitting antenna must be located on that Tribal Applicant's “Tribal Lands,” as defined in § 73.7000. Applicants claiming a point for this criterion must submit the documentation set forth in FCC Form 318 at the time of filing their applications.
(c) Voluntary time-sharing. If mutually exclusive applications have the same point total, no more than three of the tied applicants may propose to share use of the frequency by electronically submitting, within 90 days of the release of a public notice announcing the tie, a time-share proposal. Such proposals shall be treated as minor amendments to the time-share proponents' applications and shall become part of the terms of the station authorization. Where such proposals include all of the tied applications, all of the tied applications will be treated as tentative selectees; otherwise, time-share proponents' points will be aggregated. Applicants may agree, at any time before the Media Bureau implements the involuntary time-share procedures pursuant to paragraph (d) of this section, to aggregate their points to enter into a time-share agreement. Applicants can only aggregate their points and submit a time-share agreement if each is designated a tentative selectee in the same mutually exclusive group, and if each applicant has the basic qualifications to receive a grant of its application.
(1) Time-share proposals shall be in writing and signed by each time-share proponent, and shall satisfy the following requirements:
(i) The proposal must specify the proposed hours of operation of each time-share proponent;
(ii) The proposal must not include simultaneous operation of the time-share proponents; and
(iii) Each time-share proponent must propose to operate for at least 10 hours per week.
(2) Where a station is authorized pursuant to a time-sharing proposal, a change of the regular schedule set forth therein will be permitted only where a written agreement signed by each time-sharing permittee or licensee and complying with requirements in paragraphs (c)(1)(i) through (iii) of this section is filed with the Commission, Attention: Audio Division, Media Bureau, prior to the date of the change.
(3) Where a station is authorized pursuant to a voluntary time-sharing proposal, the parties to the time-sharing agreement may apportion among themselves any air time that, for any reason, becomes vacant.
(4) Concurrent license terms granted under paragraph (d) of this section may be converted into voluntary time-sharing arrangements renewable pursuant to § 73.3539 by submitting a universal time-sharing proposal.
(5) In the event a tentatively accepted time-share agreement is dismissed, the Commission staff will release another public notice, initiating a second 90-day period for all remaining tentative selectees within the affected MX group to enter into either a voluntary time-share arrangement or a universal settlement in accordance with paragraph (c) or (e) of this section. If the tie is not resolved in accordance with paragraph (c) or (e) of this section, the tied applications will be reviewed for acceptability, and applicants with tied, grantable applications will be eligible for involuntary time-sharing in accordance with paragraph (d) of this section.
(d) Involuntary time-sharing. (1) If a tie among mutually exclusive applications is not resolved through voluntary time-sharing in accordance with paragraph (c) of this section, the tied applications will be reviewed for acceptability. Applicants with tied, grantable applications will be eligible for equal, concurrent, non-renewable license terms.
(2) If a mutually exclusive group has three or fewer tied, grantable applications, the Commission will simultaneously grant these applications, assigning an equal number of hours per week to each applicant. The Commission will determine the hours assigned to each applicant by first assigning hours to the applicant that has been local, as defined in § 73.853(b), for the longest uninterrupted period of time, then assigning hours to the applicant that has been local for the next longest uninterrupted period of time, and finally assigning hours to any remaining applicant. The Commission will offer applicants an opportunity to voluntarily reach a time-sharing agreement. In the event that applicants cannot reach such agreement, the Commission will require each applicant subject to involuntary time-sharing to simultaneously and confidentially submit their preferred time slots to the Commission. If there are only two tied, grantable applications, the applicants must select between the following 12-hour time slots 3 a.m.-2:59 p.m., or 3 p.m.-2:59 a.m. If there are three tied, grantable applications, each applicant must rank their preference for the following 8-hour time slots: 2 a.m.-9:59 a.m., 10 a.m.-5:59 p.m., and 6 p.m.-1:59 a.m. The Commission will require the applicants to certify that they did not collude with any other applicants in the selection of time slots. The Commission will give preference to the applicant that has been local for the longest uninterrupted period of time. The Commission will award time in units as small as four hours per day. In the event an applicant neglects to designate its preferred time slots, staff will select a time slot for that applicant.
(3) Groups of more than three tied, grantable applications will not be eligible for licensing under this section. Where such groups exist, the Commission will dismiss all but the applications of the three applicants that have been local, as defined in § 73.853(b), for the longest uninterrupted periods of time. The Commission then will process the remaining applications as set forth in paragraph (d)(2) of this section.
(4) If concurrent license terms granted under this section are converted into universal voluntary time-sharing arrangements pursuant to paragraph (c)(4) of this section, the permit or license is renewable pursuant to §§ 73.801 and 73.3539.
(e) Settlements. Mutually exclusive applicants may propose a settlement at any time during the selection process after the release of a public notice announcing the mutually exclusive groups. Settlement proposals must comply with the Commission's rules and policies regarding settlements, including the requirements of §§ 73.3525, 73.3588 and 73.3589. Settlement proposals may include time-share agreements that comply with the requirements of paragraph (c) of this section, provided that such agreements may not be filed for the purpose of point aggregation outside of the 90 day period set forth in paragraph (c) of this section.
§ 73.873   LPFM license period.
(a) Initial licenses for LPFM stations will be issued for a period running until the date specified in § 73.1020 for full service stations operating in the LPFM station's state or territory, or if issued after such date, determined in accordance with § 73.1020.
(b) The license of an LPFM station that fails to transmit broadcast signals for any consecutive 12-month period expires as a matter of law at the end of that period, notwithstanding any provision, term, or condition of the license to the contrary.
§ 73.875   Modification of transmission systems.
The following procedures and restrictions apply to licensee modifications of authorized broadcast transmission system facilities.
(a) The following changes are prohibited:
(1) Those that would result in the emission of signals outside of the authorized channel exceeding limits prescribed for the class of service.
(2) Those that would cause the transmission system to exceed the equipment performance measurements prescribed in § 73.508.
(b) The following changes may be made only after the grant of a construction permit application on FCC Form 318.
(1) Any construction of a new tower structure for broadcast purposes, except for replacement of an existing tower with a new tower of identical height and geographic coordinates.
(2) Any change in station geographic coordinates, including coordinate corrections and any move of the antenna to another tower structure located at the same coordinates.
(3) Any change in antenna height more than 2 meters above or 4 meters below the authorized value.
(4) Any change in channel.
(c) The following LPFM modifications may be made without prior authorization from the Commission. A modification of license application (FCC Form 319) must be submitted to the Commission within 10 days of commencing program test operations pursuant to § 73.1620. For applications filed pursuant to paragraph (c)(1) of this section, the modification of license application must contain an exhibit demonstrating compliance with the Commission's radiofrequency radiation guidelines. In addition, for applications filed solely pursuant to paragraphs (c)(1) or (2) of this section, where the installation is on or near an AM tower, as defined in § 1.30002, an exhibit demonstrating compliance with § 1.30003 or § 1.30002, as applicable, is also required.
(1) Replacement of an antenna with one of the same or different number of antenna bays, provided that the height of the antenna radiation center is not more than 2 meters above or 4 meters below the authorized values. Program test operations at the full authorized ERP may commence immediately upon installation pursuant to § 73.1620(a)(1).
(2) Replacement of a transmission line with one of a different type or length which changes the transmitter operating power (TPO) from the authorized value, but not the ERP, must be reported in a license modification application to the Commission.
(3) Changes in the hours of operation of stations authorized pursuant to time-share agreements in accordance with § 73.872.
§ 73.877   Station logs for LPFM stations.
The licensee of each LPFM station must maintain a station log. Each log entry must include the time and date of observation and the name of the person making the entry. The following information must be entered in the station log:
(a) Any extinguishment or malfunction of the antenna structure obstruction lighting, adjustments, repairs, or replacement to the lighting system, or related notification to the FAA. See §§ 17.48 and 73.49 of this chapter.
(b) Brief explanation of station outages due to equipment malfunction, servicing, or replacement;

§ 73.878   Station inspections by FCC; availability to FCC of station logs and records.
(a) The licensee of a broadcast station shall make the station available for inspection by representatives of the FCC during the station's business hours, and at any time it is in operation. In the course of an inspection or investigation, an FCC representative may require special equipment or program tests.
(b) Station records and logs shall be made available for inspection or duplication at the request of the FCC or its representatives. Such logs or records may be removed from the licensee's possession by an FCC representative or, upon request, shall be mailed by the licensee to the FCC by either registered mail, return receipt requested, or certified mail, return receipt requested. The return receipt shall be retained by the licensee as part of the station records until such records or logs are returned to the licensee. A receipt shall be furnished when the logs or records are removed from the licensee's possession by an FCC representative and this receipt shall be retained by the licensee as part of the station records until such records or logs are returned to the licensee. When the FCC has no further need for such records or logs, they shall be returned to the licensee. The provisions of this rule shall apply solely to those station logs and records that are required to be maintained by the provisions of this part.
(1) Where records or logs are maintained as the official records of a recognized law enforcement agency and the removal of the records from the possession of the law enforcement agency will hinder its law enforcement activities, such records will not be removed pursuant to this section if the chief of the law enforcement agency promptly certifies in writing to the FCC that removal of the logs or records will hinder law enforcement activities of the agency, stating insofar as feasible the basis for his decision and the date when it can reasonably be expected that such records will be released to the FCC.
§ 73.879   Signal retransmission.
An LPFM licensee may not retransmit, either terrestrially or via satellite, the signal of a full-power radio broadcast station.
§ 73.881   Equal employment opportunities.
General EEO policy. Equal employment opportunity shall be afforded by all LPFM licensees and permittees to all qualified persons, and no person shall be discriminated against because of race, color , religion, national origin, or sex.

§ 73.1030   Notifications concerning interference to radio astronomy, research and receiving installations.
(a)(1) Radio astronomy and radio research installations. In order to minimize harmful interference at the National Radio Astronomy Observatory site located at Green, Pocahontas County, West Virginia, and at the Naval Radio Research Observatory at Sugar Grove, Pendleton County, West Virginia, a licensee proposing to operate a short-term broadcast auxiliary station pursuant to § 74.24 of this chapter, and any applicant for authority to construct a new broadcast station, or for authority to make changes in the frequency, power, antenna height, or antenna directivity of an existing station within the area bounded by 39°15′ N on the north, 78°30′ W on the east, 37°30′ N on the south, and 80°30′ W on the west, shall notify the Interference Office, National Radio Astronomy Observatory, P.O. Box 2, Green Bank, West Virginia 24944. Telephone: (304) 456-2011; Email: nrqz@nrao.edu. The notification shall be in writing and set forth the particulars of the proposed station, including the geographical coordinates of the antenna, antenna height, antenna directivity if any, proposed frequency, type of emission and power. The notification shall be made prior to, or simultaneously with, the filing of the application with the Commission. After receipt of such applications, the FCC will allow a period of 20 days for comments or objections in response to the notifications indicated. If an objection to the proposed operation is received during the 20-day period from the National Radio Astronomy Observatory for itself, or on behalf of the Naval Radio Research Observatory, the FCC will consider all aspects of the problem and take whatever action is deemed appropriate.
(2) Any applicant for a new permanent base or fixed station authorization to be located on the islands of Puerto Rico, Desecheo, Mona, Vieques, and Culebra, or for a modification of an existing authorization which would change the frequency, power, antenna height, directivity, or location of a station on these islands and would increase the likelihood of the authorized facility causing interference, shall notify the Interference Office, Arecibo Observatory, HC3 Box 53995, Arecibo, Puerto Rico 00612, in writing or electronically, of the technical parameters of the proposal. Applicants may wish to consult interference guidelines, which will be provided by Cornell University. Applicants who choose to transmit information electronically should e-mail to: prcz@naic.edu.
(i) The notification to the Interference Office, Arecibo Observatory shall be made prior to, or simultaneously with, the filing of the application with the Commission. The notification shall state the geographical coordinates of the antenna (NAD-83 datum), antenna height above ground, ground elevation at the antenna, antenna directivity and gain, proposed frequency and FCC Rule Part, type of emission, and effective radiated power.
(ii) After receipt of such applications, the Commission will allow the Arecibo Observatory a period of 20 days for comments or objections in response to the notification indicated. The applicant will be required to make reasonable efforts to resolve or mitigate any potential interference problem with the Arecibo Observatory and to file either an amendment to the application or a modification application, as appropriate. The Commission shall determine whether an applicant has satisfied its responsibility to make reasonable efforts to protect the Observatory from interference.
(b) Radio receiving installations. Protection for Table Mountain Radio Receiving Zone, Boulder County, Colorado: Applicants for a station authorization to operate in the vicinity of Boulder County, Colorado under this Part are advised to give due consideration, prior to filing applications, to the need to protect the Table Mountain Radio Receiving Zone from harmful interference. These are the research laboratories of the Department of Commerce, Boulder County, Colorado. To prevent degradation of the present ambient radio signal level at the site, the Department of Commerce seeks to ensure that the field strengths of any radiated signals (excluding reflected signals) received on this 1800 acre site (within the area bounded by 40°09′10″ N Latitude on the north, 105°13′31″ W Longitude on the east, 40°07′05″ N Latitude on the south, and 105°15′13″ W Longitude on the west) resulting from new assignments (other than mobile stations) or from the modification of relocation of existing facilities do not exceed the following values:
1 Equivalent values of power flux density are calculated assuming free space characteristic impedance of 376.7 = 120 ohms.
2 Space stations shall conform to the power flux density limits at the earth's surface specified in appropriate parts of the FCC rules, but in no case should exceed the above levels in any 4 kHz band for all angles of arrival.
(1) Advance consultation is recommended particularly for those applicants who have no reliable data which indicates whether the field strength or power flux density figures in the above table would be exceeded by their proposed radio facilities (except mobile stations). In such instances, the following is a suggested guide for determining whether coordination is recommended:
(i) All stations within 2.4 km (1.5 statute miles);
(ii) Stations within 4.8 km (3 statute miles) with 50 watts or more effective radiated power (ERP) in the primary plane polarization in the azimuthal direction of the Table Mountain Radio Receiving Zone;
(iii) Stations within 16 km (10 statute miles) with 1 kW or more ERP in the primary plane of polarization in the azimuthal direction of Table Mountain Receiving Zone;
(iv) Stations within 80 km (50 statute miles) with 25 kW or more ERP in the primary plane polarization in the azimuthal direction of Table Mountain Receiving Zone.
(2) Applicants concerned are urged to communicate with the Radio Frequency Management Coordinator, Institute for Telecommunication Sciences, 325 Broadway, Boulder, CO 80305; telephone (303) 497-4220, email frequencymanager@ntia.gov, in advance of filing their applications with the Commission.
(3) The Commission will not screen applications to determine whether advance consultation has taken place. However, applicants are advised that such consultation can avoid objectimns from the Department of Commerce or proceedings to modify any authorization which may be granted which, in fact, delivers a signal at the site in excess of the field strength specified herein.
(c) Protection for Federal Communications Commission monitoring stations. (1) Applicants in the vicinity of a FCC monitoring station for a radio station authorization to operate new transmitting facilities or changed transmitting facilities which would increase the field strength produced over the monitoring station in excess of that previously authorized are advised to give consideration, prior to filing applications, to the possible need to protect the FCC stations from harmful interference. Geographical coordinates of the facilities which require protection are listed in § 0.121(c) of the FCC rules. Applications for stations (except mobile stations) which will produce on any frequency a direct wave fundamental field strength of greater than 10 mV/m in the authorized bandwidth of service (−65.8 dBW/m 2 power flux density assuming a free space characteristic impedance of 120 π ohms) at the referenced coordinates, may be examined to determine extent of possible interference. Depending on the theoretical field strength value and existing root-sum-square or other ambient radio field signal levels at the indicated coordinates, a clause protecting the monitoring station may be added to the station authorization.
(2) In the event that calculated value of expected field exceeds 10 mV/m (−65.8 dBW/m2) at the reference coordinates, or if there is any question whether field strength levels might exceed the threshold value, advance consultation with the FCC to discuss any protection necessary should be considered. Prospective applicants may communicate with the Public Safety and Homeland Security Bureau.
(3) Advance consultation is suggested particularly for those applicants who have no reliable data which indicates whether the field strength or power flux density figure indicated would be exceeded by their proposed radio facilities (except mobile stations). In such instances, the following is a suggested guide for determining whether an applicant should coordinate:
(i) All stations within 2.4 kilometers (1.5 statute miles);
(ii) Stations within 4.8 kilometers (3 statute miles) with 50 watts or more average effective radiated power (ERP) in the primary plane of polarization in the azimuthal direction of the Monitoring Stations.
(iii) Stations within 16 kilometers (10 statute miles) with 1 kW or more average ERP in the primary plane of polarization in the azimuthal direction of the Monitoring Station;
(iv) Stations within 80 kilometers (50 statute miles) with 25 kW or more average ERP in the primary plane of polarization in the azimuthal direction of the Monitoring Station;
(4) Advance coordination for stations operating above 1000 MHz is recommended only where the proposed station is in the vicinity of a monitoring station designated as a satellite monitoring facility in § 0.121(c) of the Commission's Rules and also meets the criteria outlined in paragraphs (b) (2) and (3) of this section.
(5) The Commission will not screen applications to determine whether advance consultation has taken place. However, applicants are advised that such consultation can avoid objections from the Federal Communications Commission or modification of any authorization which will cause harmful interference.
§ 73.1120   Station location.
Each AM, FM, TV and Class A TV broadcast station will be licensed to the principal community or other political subdivision which it primarily serves. This principal community (city, town or other political subdivision) will be considered to be the geographical station location.
§ 73.1125   Station telephone number.
Each AM, FM, TV, and Class A TV broadcast station shall maintain a local telephone number in its community of license or a toll-free number.
§ 73.1150   Transferring a station.
(a) In transferring a broadcast station, the licensee may retain no right of reversion of the license, no right to reassignment of the license in the future, and may not reserve the right to use the facilities of the station for any period whatsoever.
(b) No license, renewal of license, assignment of license or transfer of control of a corporate licensee will be granted or authorized if there is a contract, arrangement or understanding, express or implied, pursuant to which, as consideration or partial consideration for the assignment or transfer, such rights, as stated in paragraph (a) of this section, are retained.
(c) Licensees and/or permittees authorized to operate in the 535-1605 kHz and in the 1605-1705 kHz band pursuant to the Report and Order in MM Docket No. 87-267 will not be permitted to assign or transfer control of the license or permit for a single frequency during the period that joint operation is authorized.
