Ex Parte Rules—Permit but Disclose. 

Pursuant to § 1.1200(a) of the 

Commission’s rules, this Notice of 

Proposed Rulemaking (NPRM) shall be 

treated as a ’’permit-but-disclose’’ 

proceeding in accordance with the 

Commission’s ex parte rules. Persons 

making ex parte presentations must file 

a copy of any written presentation or a 

memorandum summarizing any oral 

presentation within two business days 

after the presentation (unless a different 

deadline applicable to the Sunshine 

period applies). Persons making oral ex 

parte presentations are reminded that 

memoranda summarizing the 

presentation must (1) list all persons 

attending or otherwise participating in 

the meeting at which the ex parte 

presentation was made, and (2) 

summarize all data presented and 

arguments made during the 

presentation. If the presentation 

consisted in whole or in part of the 

presentation of data or arguments 

already reflected in the presenter’s 

written comments, memoranda, or other 

filings in the proceeding, the presenter 

may provide citations to such data or 

arguments in his or her prior comments, 

memoranda, or other filings (specifying 

the relevant page and/or paragraph 

numbers where such data or arguments 

can be found) in lieu of summarizing 

them in the memorandum. Documents 

shown or given to Commission staff 

during ex parte meetings are deemed to 

be written ex parte presentations and 

must be filed consistent with rule 

1.1206(b). In proceedings governed by 

rule 1.49(f) or for which the 

Commission has made available a 

method of electronic filing, written ex 

parte presentations and memoranda 

summarizing oral ex parte 

presentations, and all attachments 

thereto, must be filed through the 

electronic comment filing system 

available for that proceeding, and must 

be filed in their native format (e.g., .doc, 

.xml, .ppt, searchable .pdf). Participants 

in this proceeding should familiarize 

themselves with the Commission’s ex 

parte rules. 

Synopsis 

In the Notice of Proposed Rulemaking 

(NPRM), the Commission proposes to: 

(1) implement certain WRC–15 

allocation decisions not previously 

addressed; (2) make other allocation 

changes that are not related to WRC–15 

implementation; and (3) revise parts 2, 

25, 74, 78, 90, 97, and 101 of the rules 

to reflect the proposed allocation 

changes. Proposals that are not related 

to WRC–15 implementation are: (1) 

restricting the use of the mobile-satellite 

service (Earth-to-space) in the frequency 

bands designated for use by the 

Automatic Identification System (AIS 1– 

4) to non-Federal space station 

reception of AIS messages; (2) deleting 

the broadcasting service allocation from 

the 700 MHz band; (3) updating the 

rules to recognize that the transition 

period for the reallocation of the 18.3– 

19.3 GHz band from the fixed service to 

the fixed-satellite service (space-toEarth) has concluded; and (4) removing 

eight inactive call signs from 

§ 2.106(d)(62) (footnote NG62 or NG62). 

A. Satellite Issues 

1. Protection of Search and Rescue 

Satellites Receiving in the 406–406.1 

MHz Band 

The Commission proposes to adopt 

new § 2.106(c)(265) (footnote US265 or 

US265) for the 403–410 MHz band to 

protect satellite-based search and rescue 

systems operating in the 406–406.1 MHz 

band from out-of-band emissions 

originating from operations in adjacent 

bands, as provided in Resolution 205 

(Rev.WRC–19). The Commission’s rules 

authorize Emergency PositionIndicating Radio Beacon, Emergency 

Locator Transmitter, and Personal 

Locator Beacon transmissions to Federal 

Government satellites that carry Search 

and Rescue Satellite (SARSAT) 

receivers. The National Oceanic and 

Atmospheric Administration (NOAA) 

operates polar orbiting and 

geostationary satellites that carry 

payloads providing distress alert and 

location information to appropriate 

public safety rescue authorities for 

maritime, aviation, and land users in 

distress. 47 CFR 80.209(a)(7), 

80.905(a)(3)(vi), (a)(4)(vi), 80.1077, 

80.1129(c), 87.139(h), 87.147(e), 

87.173(b), 87.187(m), 87.195(a), 87.199, 

95.2963, and 95.2971. Proposed US265 

would prohibit new frequency 

assignments within the 405.9–406.0 

MHz and 406.1–406.2 MHz bands under 

the mobile and fixed services 

allocations. Assignment (of a radio 

frequency or radio frequency channel) is 

defined as an authorization given by an 

administration for a radio station to use 

a radio frequency or radio frequency 

channel under specified conditions. 47 

CFR 2.1(c). In general, the assignment of 


lotter on DSK11XQN23PROD with PROPOSALS1
67162 Federal Register / Vol. 88, No. 188 / Friday, September 29, 2023 / Proposed Rules 

frequencies and frequency bands must 

be in accordance with the Allocation 

Table. 47 CFR 2.102(a). The radio 

frequency devices authorized pursuant 

to 47 CFR part 15 are not based on 

allocated radio services. Note 1 to 

paragraph (e) of § 2.105. The term 

‘‘short-range radiocommunication 

devices’’ is intended to cover radio 

transmitters that have low capability of 

causing interference to other radio 

equipment. In general, such devices are 

permitted to operate on a noninterference, no-protection-frominterference basis. Simple licensing 

requirements may be applied, e.g. 

general licenses or general frequency 

assignments or even license exemption. 

See Recommendation ITU–R SM.1538– 

1, Annex 1, p. 2 at 2 (Definition of shortrange radiocommunication devices). 

Medical Device Radio Communications 

(MedRadio) devices, similar to part 15 

devices, are short-range devices. 

For radiosonde applicants that seek to 

operate in the 403–410 MHz band, 

proposed US265 would require that the 

frequency drift characteristics of 

radiosondes be taken into account when 

selecting operating frequencies above 

405 MHz to avoid transmitting in the 

406–406.1 MHz band and that all 

practical steps be taken to avoid the 

operating frequency drifting close to 406 

MHz. The 403–406 MHz band is a 

Federal/non-Federal shared band that is 

allocated to the meteorological aids 

service (radiosonde) on a primary basis. 

The Commission licenses radiosondes 

under its part 5 experimental radio 

service; however, there are currently no 

active licenses for non-Federal 

radiosonde use of the 403–406 MHz 

band. 47 CFR part 5. Proposed US265 

seeks to address concerns that aggregate 

levels of electromagnetic interference, 

including interference from 

transmissions in adjacent frequency 

bands, may present a risk of satellite 

emergency transmissions being 

undetected, or delayed in reception, or 

lead to reduced accuracy of the 

calculated locations. The Commission 

seeks comment on this proposal. 

Currently, non-Federal use of the 

fixed and mobile services in the 

adjacent 403–406 MHz and 406.1–410 

MHz bands is permitted pursuant to 47 

CFR 2.106(c)(13), (55), (64) (footnotes 

US13, US55, and US64, or US13, US55, 

and US64). Footnote US64 states, inter 

alia, that the 401–406 MHz band is 

allocated to the mobile, except 

aeronautical mobile, service on a 

secondary basis, and that non-Federal 

use is limited to medical device 

radiocommunication service 

(MedRadio) operations. MedRadio is an 

ultra-low power radio service that is 

associated with medical implant devices 

and medical body-worn devices. 

MedRadio stations are licensed-by-rule 

and operate in accordance with part 95, 

subpart I of the rules, so the 

Commission does not issue individual 

station licenses for MedRadio devices. 

Hence, the Commission tentatively 

concluded that continued operations of 

MedRadio devices are consistent with 

proposed US265. The Commission seeks 

comment on this tentative conclusion. 

Section 2.106(c)(13) (footnote US13 or 

US13) and § 90.265 of the Commission’s 

rules make 48 channels available for 

transmitting hydrological and 

meteorological data (Hydro channels), 

including channels with center 

frequencies 406.125 MHz and 406.175 

MHz. The Commission proposes to 

revise §§ 2.106 and 90.265 to state that, 

after the effective date of final rules in 

this proceeding, no assignments for the 

frequencies 406.1250 MHz and 406.1750 

MHz will be made, and that existing 

stations may continue to operate 

indefinitely on these frequencies as they 

are currently licensed. As of April 18, 

2023, 63 licenses in the Commission’s 

Universal Licensing System authorized 

operation in the 406.125–406.175 MHz 

band. This NPRM does not modify those 

licenses. By no longer issuing licenses 

for the frequencies 406.1250 MHz and 

406.1750 MHz, the Commission would 

ensure consistency with proposed new 

footnote US265 and protect satellitebased search and rescue systems 

operating in the adjacent 406–406.1 

MHz band from out-of-band emissions 

originating on those frequencies. The 

Commission seeks comment on these 

proposals. 

Section 2.106(c)(55) (footnote US55 or 

US55) provides that the Commission 

may authorize public safety use of 40 

Federal Interoperability Channels that 

are designated in section 4.3.16 of the 

NTIA Manual. However, because 

section 4.3.16 of the NTIA Manual does 

not include frequencies within the 

406.1–406.2 MHz sub-band, it is not 

necessary to amend the language of this 

footnote. Finally, the Commission 

proposes to update § 2.106(c)(117) 

(footnote US117 or US117) to properly 

reflect that non-Federal use of the 

406.1–410 MHz band is limited to the 

radio astronomy service and as provided 

by footnotes US13 and US55, as shown 

in the proposed rules. This proposed 

revision of US117 was overlooked when 

the Commission originally adopted 

US55. The Commission seeks comment 

on these proposals, including any 

estimates of the costs and benefits of 

implementation. 

2. Space Research Service (Space-toSpace) in the 410–420 MHz Band 

The Commission proposes to allocate 

the 410–420 MHz band to the space 

research service (space-to-space) on a 

secondary basis for non-Federal use, 

and add § 2.106(b)(268) (footnote 5.268) 

to the non-Federal Table of Allocations 

in the 410–420 MHz band, which would 

limit use of this added space research 

service allocation to communication 

links with an orbiting, manned space 

vehicle and require compliance with a 

power flux-density limit at the Earth’s 

surface to protect existing and future 

licensees. Footnote 5.268 limits the 

power flux-density (PFD) at the surface 

of the Earth to maximum specified 

values (¥153 to ¥148 dBW/m2 in a 4 

kilohertz bandwidth) depending on the 

angle of arrival and prohibits stations in 

the space research service from claiming 

protection from, or constraining the use 

and development of, stations of the 

fixed and mobile services. 47 CFR 

2.106(b)(268). The 410–420 MHz band is 

currently allocated to the fixed, mobile, 

and space research (space-to-space) 

services on a primary basis for Federal 

use; the 413–419 MHz segment is 

allocated to the mobile, except 

aeronautical mobile, service on a 

secondary basis, with non-Federal use 

limited to part 95 MedRadio operations. 

47 CFR 2.106(a). The National 

Aeronautics and Space Administration 

(NASA) operates systems in support of 

extra-vehicular activity communications 

for the manned space program and other 

space related efforts in this band. The 

systems are used for communications 

between crew members and for relaying 

telemetry data to the main spacecraft. 

Non-Federal use is limited to MedRadio 

operations, hydrological/meteorological 

data, and public safety. The 

Commission expects that the additional 

non-Federal use would be similar to the 

current Federal uses and would occur 

because of increasing space exploration 

by private companies. The Commission 

requests comment on these proposals, 

including information on the costs and 

benefits. 

3. Global Flight Tracking for Civil 

Aviation (1087.7–1092.3 MHz) 

The Commission proposes to allocate 

the 1087.7–1092.3 MHz band to the 

aeronautical mobile-satellite (route) 

service (Earth-to-space) on a primary 

basis, limited to space station reception 

of automatic dependent surveillancebroadcast (ADS–B) emissions from 

aircraft. If adopted, the Commission 

would implement this proposed 

allocation by referencing 

§ 2.106(b)(328)(ii) (footnote 5.328AA) in 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 88, No. 188 / Friday, September 29, 2023 / Proposed Rules 67163 

the 960–1164 MHz band within the U.S. 

Table. The 960–1164 MHz band is 

currently allocated to the aeronautical 

mobile (route) and aeronautical 

radionavigation services on a primary 

basis for Federal and non-Federal use. 

Aircraft currently transmit ADS–B 

signals to report their position to 

ground-based receivers in a 4.6- 

megahertz wide band centered on 1090 

MHz under the existing aeronautical 

mobile (route) service allocation. This 

proposed allocation would extend 

reception of ADS–B signals beyond 

terrestrial line-of-sight to facilitate 

reporting the position of aircraft located 

anywhere in the world. The 

Commission tentatively concluded that 

providing for satellite reception of ADS– 

B signals would ensure the efficient 

management of air traffic in oceanic, 

polar, and remote airspace. Further, the 

Commission tentatively concluded that 

this proposed allocation would support 

the Federal Aviation Administration’s 

rules regarding aircraft location 

information. The Commission also 

proposes to add new paragraph (a)(13) 

to § 25.202 of the Commission’s rules to 

permit the licensing of space stations 

that can receive ADS–B emissions from 

aircraft. The Commission seeks 

comment on these proposals. 

Further, as recommended by the 

National Telecommunications and 

Information Administration (NTIA), the 

Commission proposes to add new 

paragraph (78) to § 2.106(c) (footnote 

US78 or US78) to the 960–1164 MHz 

band to recognize Federal use by 

military Identification Friend or Foe 

(IFF) systems on center frequencies 

1030/1090 MHz. The Commission 

proposes this use would be subject to 

the condition that harmful interference 

would not be caused to the aeronautical 

radionavigation service or the 

aeronautical mobile (R) service. Finally, 

the Commission proposes to revise 

§ 2.106(c)(224) (footnote US224 or 

US224) to require that Federal systems 

utilizing spread spectrum techniques for 

terrestrial communication, navigation, 

and identification in the 960–1215 MHz 

band be authorized on the condition 

that harmful interference not be caused 

to the aeronautical mobile (R) and 

aeronautical radionavigation services in 

the 960–1164 MHz band, military IFF 

systems on center frequencies 1030/ 

1090 MHz, aeronautical mobile-satellite 

(R) service (Earth-to-space) in the 

1087.7–1092.3 MHz band, and the 

aeronautical radionavigation and 

radionavigation-satellite (space-to-Earth) 

(space-to-space) services in the 1164– 

1215 MHz band. The Commission 

requests comment on these proposals, 

including whether any modifications to 

the part 87 rules for aviation services 

would be necessary to implement these 

proposals. 

4. Satellite Uplinks in the 7190–7250 

MHz Band 

As recommended by NTIA, the 

Commission seeks comment on whether 

to provide additional spectrum on a 

secondary basis for non-Federal Earthto-space operations in the Earth 

exploration-satellite service in the 

7190–7250 MHz band and space 

research service in the 7190–7235 MHz 

band. In the U.S. Table, the 7190–7250 

MHz band is allocated to the Earth 

exploration-satellite (Earth-to-space) 

and fixed services, both on a primary 

basis and exclusively for Federal use. 

The 7190–7235 MHz portion of the band 

is also allocated on a primary basis to 

the space research service (Earth-tospace) exclusively for Federal use. 

Consistent with NTIA’s 

recommendation, should the 

Commission make these Federal uplink 

bands available for non-Federal use on 

a secondary basis for Earth-to-space 

operations in the Earth explorationsatellite and space research services, 

respectively, by adding the provisions of 

proposed §§ 2.106(c)(460) and (460)(i) 

(footnote US460 or US460; footnote 

US460A or US460A) to the 7190–7235 

MHz band and footnote US460A to the 

7235–7250 MHz band? Footnote US460 

would provide a secondary non-Federal 

allocation in the 7190–7235 MHz band 

for the space research service (Earth-tospace) and would prohibit emissions 

from such systems intended for deep 

space. Footnote US460A would allocate 

the 7190–7250 MHz band to the Earth 

exploration-satellite service (Earth-tospace) on a secondary basis for nonFederal use, limited to tracking, 

telemetry, and command (TT&C) for the 

operation of spacecraft. The restrictions 

in footnotes US460 and US460A are 

based on international §§ 2.106(b)(460), 

(460)(i) (footnotes 5.460 and 5.460A, or 

5.460 and 5.460A). In both cases, should 

the Commission explicitly require that 

authorizations be subject to a case-bycase electromagnetic compatibility 

(EMC) analysis and approval? 

Qualcomm urged the Commission to 

seek comment on whether such 

allocations would ‘‘remain in line with 

the Commission’s present spectrum 

priorities,’’ noting that the Chairwoman 

has identified the 7–15 GHz spectrum 

range, and some stakeholders, other 

administrations, and regional 

organizations are considering the 7190– 

7250 MHz band for the next generation 

wireless technology. The Commission 

requests comment on these 

recommendations. 

5. Earth Exploration-Satellite Service 

(Active) in the 9.2–9.3 GHz and 9.9–10.4 

GHz Bands 

The Commission seeks comment on 

allocating the 9.2–9.3 GHz and 9.9–10.4 

GHz bands to the Earth explorationsatellite service (active) on a primary 

basis for Federal use and on a secondary 

basis for non-Federal use, subject to 

§§ 2.106(b)(474)(i), (b)(474)(ii), 

(b)(474)(iii), and proposes 

§ 2.106(c)(474) (footnotes 5.474A, 

5.474B, 5.474C, and US474D, or 5.474A, 

5.474B, 5.474C, and US474D, 

respectively). Footnote US474D is based 

on the text in § 2.106(b)(474)(iv) 

(international footnote 5.474D or 

5.474D), except that the radiolocation 

service is not included in the 9.2–9.3 

GHz band because this allocation has 

secondary status in both the Federal and 

non-Federal Tables, and the 

radionavigation service is not included 

in the 9.9–10 GHz band because that 

allocation only applies in the countries 

listed in § 2.106(b)(478) (footnote 5.478 

or 5.478). This would implement WRC– 

15’s expansion of the current worldwide 

Earth exploration-satellite service 

(active) allocation in the 9.3–9.9 GHz 

band by allocating 600 megahertz of 

additional spectrum in the adjacent 

bands to this service, which would 

support the growing demand for greater 

radar image resolution to satisfy global 

environmental monitoring 

requirements. Spaceborne radars 

operating in this band support a large 

number of scientific and geoinformation 

applications, such as disaster relief and 

humanitarian aid, land use, and large 

area coastal surveillance. The 

Commission requests comment on these 

potential allocations. 

In the U.S. Table, the 9.2–9.3 GHz 

band is allocated to the maritime 

radionavigation service on a primary 

basis and to the radiolocation service on 

a secondary basis for Federal and nonFederal use, subject to §§ 2.106(b)(472), 

(b)(474), (c)(110), and (e)(59) (footnotes 

5.472, 5.474, US110, and G59, or 5.472, 

5.474, US110, and G59, respectively. 

The 9.9–10.5 GHz band is allocated to 

the radiolocation service on a primary 

basis for Federal use and on a secondary 

basis for non-Federal use. The 9.975– 

10.025 GHz band is also allocated to the 

meteorological-satellite service on a 

secondary basis for use by weather 

radars. 47 CFR 2.106(b)(479). The 10– 

10.5 GHz and 10.45–10.5 GHz bands are 

allocated to the amateur and amateursatellite services on a secondary basis, 

respectively. Five footnotes apply to the 

10–10.5 GHz band: 47 CFR 


lotter on DSK11XQN23PROD with PROPOSALS1

2.106(b)(479), (c)(108), (c)(128), (d)(50), 

and (e)(32) (footnotes 5.479, US108, 

US128, NG50, and G32, or 5.479, 

US108, US128, NG50, and G32, 

respectively). The 2023 World 

Radiocommunication Conference will 

consider whether to identify the 10–10.5 

GHz for International Mobile 

Telecommunications (IMT) in ITU 

Region 2. 

The four footnotes on which the 

Commission seeks comment on adding 

to the 9.2–9.3 GHz and 9.9–10.4 GHz 

bands would limit their use to systems 

in the Earth exploration-satellite service 

(active) requiring a necessary bandwidth 

greater than 600 megahertz that cannot 

be fully accommodated within the 9.3– 

9.9 GHz band (5.474A 

(§ 2.106(b)(474)(i))); protect the radio 

astronomy service in the 10.6–10.7 GHz 

band from unwanted emissions (5.474B 

(§ 2.106(b)(474)(ii))); protect the space 

research service (space-to-Earth) in the 

8.4–8.5 GHz band from unwanted 

emissions (5.474C (§ 2.106(b)(474)(iii))); 

and require that the Earth explorationsatellite service (active) not cause 

harmful interference to, or claim 

protection from, the maritime 

radionavigation service in the 9.2–9.3 

GHz band and the radiolocation service 

in the 9.9–10.4 GHz band (proposed 

US474D (§ 2.106(c)(474)). Qualcomm 

urged the Commission to seek comment 

on whether the proposed allocations 

would ‘‘remain in line with the 

Commission’s present spectrum 

priorities,’’ noting that the Chairwoman 

has identified the 7–15 GHz spectrum 

range, and some stakeholders, other 

administrations, and regional 

organizations are considering the 9.2– 

9.3 GHz and 9.9–10.4 GHz bands for the 

next generation wireless technology. 

The Commission also proposes to 

revise § 2.106(c)(128) (footnote US128 or 

US128) to support the Department of 

Defense’s development of pulsed 

emission systems in the 10–10.5 GHz 

band. Currently, US128 prohibits pulsed 

emissions in the 10–10.5 GHz band, 

except for weather radars on board 

meteorological satellites in the 10– 

10.025 GHz sub-band. Under footnote 

US128, the amateur, the amateursatellite, and the non-Federal 

radiolocation services, which shall not 

cause harmful interference to the 

Federal radiolocation service, are the 

only non-Federal services permitted in 

the 10–10.5 GHz band, and the nonFederal radiolocation service is limited 

to survey operations as specified in 

§ 2.106(c)(108) (footnote US108 or 

US108). NTIA states that the 

Department of Defense requires 

flexibility for development of pulsed 

systems in this band to meet future 

system needs. The Commission seeks 

comment on all of the proposals in this 

section. In addition, it requests 

comment on whether the 9.2–9.8 GHz 

and 9.9–10.4 GHz bands should be 

allocated to the Earth explorationsatellite service (active) on a primary 

basis for non-Federal use, so the status 

of those non-Federal allocations would 

mirror the status of the Federal Earth 

exploration-satellite service (active) 

allocations in those bands. 

6. Revision of the 18.142–19.3 GHz, 

28.5–29.1 GHz, and 29.25–29.5 GHz 

Bands 

In this section, the Commission makes 

proposals and seeks comments on 

allocation and service rule changes that 

would clarify the status of grandfathered 

fixed stations in the 18.3–19.3 GHz band 

and permit a heavier use of the fixedsatellite service (FSS) in the 18.142–18.3 

GHz, 28.5–29.1 GHz, and 29.25–29.5 

GHz bands. 

First, the Commission proposes to 

amend § 2.106(c)(139) (footnote US139 

or US139) by stating that, in the 18.3– 

19.3 GHz band, earth station licensees 

in the fixed-satellite service (space-toEarth) may require that licensees of 

grandfathered stations in the fixed 

service cease operations, consistent with 

the provisions in § 101.95 of the 

Commission’s rules. The Commission 

makes this proposal because, in the 

18.3–19.3 GHz band, there is no fixed 

service allocation and there are no 

longer any primary grandfathered fixed 

stations. Specifically, § 101.85 states 

that fixed service operations in the 

18.3–18.58 GHz and 18.58–19.3 GHz 

bands that remain co-primary under the 

provisions of §§ 74.502(c), 74.602(g), 

78.18(a)(4), and 101.147(r) will continue 

to be co-primary with the fixed-satellite 

service (FSS) until dates that have long 

since passed, i.e., these transition 

periods have concluded. In addition, 

§ 101.95(a), which concerns the sunset 

provisions for the 18.3–19.3 GHz band, 

includes the following: Once the 

relocation rules sunset, an FSS licensee 

may require the incumbent to cease 

operations, provided that the FSS 

licensee intends to turn on a system 

within interference range of the 

incumbent, as determined by TIA 

Bulletin 10–F or any standard successor. 

FSS licensee notification to the affected 

FS (fixed service) licensee must be in 

writing and must provide the incumbent 

with no less than six months to vacate 

the spectrum. After the six-month notice 

period has expired, the FS licensee must 

turn its license back into the 

Commission, unless the parties have 

entered into an agreement that allows 

the FS licensee to continue to operate 

on a mutually agreed upon basis. 47 

CFR 101.85(b)(1) and (2), 101.95(a). 

Consequently, the Commission also 

proposes to revise §§ 74.502(c), 

74.602(g), 78.18(a)(4), and 101.147(r) of 

the rules in order to update the 

introductory text and the frequencies 

that are available to applicants of aural 

broadcast auxiliary stations, television 

broadcast auxiliary stations, cable 

television relay service, and fixed 

microwave services, respectively. These 

proposals are consistent with the 

Commission’s previous decision 

concerning the re-channelization of the 

17.7–18.3 GHz and 19.3–19.7 GHz 

bands for fixed microwave services 

under part 101 of the rules. While most 

of the proposed changes remove 

channels that are no longer allocated to 

the fixed service, in one instance the 

Commission proposes to add 

replacement channels, i.e., the 

Commission proposes to replace the 12 

frequency pairs in § 74.502(c)(1)(i) of the 

rules with the 5 megahertz channels 

from § 101.147(r)(5) in the proposed 

rules. The Commission also proposes to 

update §§ 101.95(a) and 101.147(a) to 

remove expired text and to remove six 

sections concerning expired policies 

governing fixed service relocation from 

the 18.3–19.3 GHz band, i.e., §§ 101.83 

through 101.91 and 101.97. The 

Commission requests comment on these 

proposals. 

Second, the Commission proposes to 

revise § 2.106(d)(62) (footnote NG62 or 

NG62) to permit the fixed stations 

authorized pursuant to the 10 listed call 

signs to continue to operate indefinitely 

on a secondary basis. The Commission 

adopted footnote NG62 when it deleted 

the primary fixed and mobile service 

allocations from the 28.5–29.1 GHz and 

29.25–29.5 GHz bands. Footnote NG62 

states that, in the 28.5–29.1 GHz and 

29.25–29.5 GHz bands, stations in the 

fixed-satellite service shall not cause 

harmful interference to, or claim 

protection from, stations in the fixed 

service operating under 18 listed call 

signs; however, only 10 of these call 

signs are currently active. The 

Commission noted that WRC–19 and the 

Commission’s rules permit earth 

stations in motion (ESIMs) to operate in 

these frequency bands. The proposed 

secondary status of these fixed stations 

would recognize that ESIMs, which may 

operate anywhere without coordination 

with the fixed stations, may cause 

intermittent interference to these fixed 

stations. The Commission requests 

comment on these proposals. 

Third, the Commission requests 

comment on whether it should raise the 

non-Federal secondary fixed-satellite 

service (space-to-Earth) allocation in the 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 88, No. 188 / Friday, September 29, 2023 / Proposed Rules 67165 

18.142–18.3 GHz band (158 megahertz) 

to primary status, i.e., co-equal with the 

non-Federal primary fixed service 

allocation in the band. If adopted, this 

upgrade of allocation status would 

provide receiving earth stations with 

interference protection from laterlicensed fixed stations that are used for 

part 74 and part 101 Multichannel 

Video Programming Distributor (MVPD) 

and part 78 cable television relay 

service (CARS) operations that operate 

in accordance with the proposed rules 

in this section. The Commission 

tentatively concluded this should result 

in significantly heavier earth station use 

of this band in the future, thereby 

enhancing spectrum efficiency. As 

background, the Commission noted that 

there are seven part 78 CARS licenses, 

which are located in three California 

counties and Maui Island, Hawaii; and 

35 grandfathered fixed service licenses 

that authorize operations in the 18.142– 

18.3 GHz band. In contrast, as of August 

26, 2022, there are 222 licenses for earth 

station reception in the 18.142–18.3 

GHz band and there are 414 pending 

applications for earth stations that 

would receive in the band. 

Finally, the Commission requests 

comment on whether it should allow 

the continued operation of existing 

CARS licenses that authorize operation 

in the 18.3–18.304 GHz and 18.3–18.334 

GHz bands in Puu Nianiau, Hawaii, and 

Placerville, California, respectively, and 

revise § 2.106(c)(139) (footnote US139 or 

US139) to codify that these fixed station 

operations may continue to operate 

indefinitely under the existing 

conditions. 

7. Deletion of the RadionavigationSatellite Service From the 149.9–150.05 

MHz and 399.9–400.05 MHz Bands 

Consistent with the WRC–15 Final 

Acts, the Commission proposes to delete 

the radionavigation-satellite service 

allocation from the 149.9–150.05 MHz 

and 399.9–400.05 MHz bands. WRC–15 

deleted this allocation because it had 

expired pursuant to footnote 5.224B. In 

the U.S. Table, the 149.9–150.05 MHz 

and 399.9–400.05 MHz bands are 

Federal/non-Federal shared bands that 

are allocated to the mobile-satellite 

service (Earth-to-space) and the 

radionavigation-satellite service on a 

primary basis. This proposal would 

make these two bands—totaling 300 

kilohertz—exclusively allocated to the 

mobile-satellite service (Earth-to-space). 

The Commission seeks comment on this 

proposal. 

B. Terrestrial Issues 

1. Amateur Service in the 5351.5–5366.5 

kHz Band 

The Commission proposes to allocate 

the 5351.5–5366.5 kHz band to the 

Amateur Radio Service on a secondary 

basis and seeks comment on whether 

the amateur service should keep the 

existing channels they use in the 60 

meter band. During WRC–15, the 

International Telecommunication Union 

(ITU) allocated this band to the amateur 

service on a secondary basis in all ITU 

Regions. The ITU generally set the 

maximum radiated power at 15 watts 

(W) equivalent isotropically radiated 

power (EIRP), which is equivalent to 

9.15 W effective radiated power (ERP). 

These frequencies are currently part 

of the 5275–5450 kHz band, which is 

allocated for Federal/non-Federal 

shared use, on a primary basis, to the 

fixed service and, on a secondary basis, 

to the mobile except aeronautical 

mobile service. Section 2.106(c)(23) 

(footnote US23 or US23) currently 

provides a secondary allocation to the 

amateur service on five discrete 

channels—each with a maximum 

bandwidth of 2.8 kilohertz and centered 

on the frequencies 5332, 5348, 5358.5, 

5373, and 5405 kHz. While footnote 

US23 does not have an explicit 

bandwidth limit, it limits use of these 

frequencies to specified emission types 

and designators, which in effect limit 

the bandwidth to a maximum of 2.8 

kilohertz, i.e. phone (2K80J3E), data 

(2K80J2D), RTTY [narrow-band directprinting telegraphy emissions having 

specified designators] (60H0J2B), and 

CW [International Morse code 

telegraphy emissions having specified 

designators] (150HA1A). 47 CFR 2.101, 

2.102, 2.106(c)(23), 97.3(c)(1), (c)(7). 

However, pursuant to Commission 

rules, stations in the amateur service 

may transmit on these frequencies with 

a maximum radiated power of 100 W 

ERP—over ten times more powerful 

than WRC–15’s EIRP limit. Footnote 

US23 and § 97.313(i) of the 

Commission’s rules state that amateur 

service use of these frequencies is 

restricted to a maximum ERP of 100 

watts ‘‘PEP’’ and that no station may 

transmit with an ERP exceeding 100 

watts ‘‘PEP,’’ respectively. These 

requirements are inconsistent with the 

definitions in part 97 of the 

Commission’s rules, i.e., PEP is the 

average power supplied to the antenna 

transmission line by a transmitter 

during one RF cycle at the crest of the 

modulation envelope taken under 

normal operating conditions and ERP is 

the product of the power supplied to the 

antenna and its gain relative to a halfwave dipole in a given direction. 47 

CFR 97.3(b)(2), (3), (9). The 

Commission’s review found that these 

rules were intended to limit the radiated 

power to 100 watts ERP based on the 

2006 agreement between NTIA and the 

American Radio Relay League, the 

National Association for Amateur Radio 

(ARRL) and, to minimize confusion, the 

Commission refers to this limit in its 

discussion. Petition for Rule Making of 

ARRL, RM–11353, at Exhibit A (filed 

Oct. 10, 2006); 47 CFR 97.313(k), (l). 

NTIA recommended that the 

Commission conform footnote US23 to 

the WRC–15 Final Acts by allocating the 

5351.5–5366.5 kHz band to the amateur 

service on a secondary basis, removing 

the four existing amateur channels 

outside this proposed new amateur 

band, and restricting the maximum 

radiated power of amateur operations in 

the band to 15 W EIRP. Federal agencies 

use the larger 5275–5450 kHz band for 

services that include military, law 

enforcement, disaster relief, emergency, 

and contingency operations. Most nonFederal operations in the 60 meter band 

are part 90 industrial business pool land 

mobile operations. 

In 2017, ARRL filed a petition for 

rulemaking asking the Commission to 

allocate the 5351.5–5366.5 kHz band to 

the amateur service on a secondary 

basis, as provided in the WRC–15 Final 

Acts, and also to retain the four amateur 

service channels that are outside this 

band (i.e., the frequencies 5332 kHz, 

5348 kHz, 5373 kHz, and 5405 kHz). 

Further, ARRL supports using the same 

operating rules in terms of permitted 

emission types, power level, and access 

by class of amateur licensee for the new 

contiguous allocation that is currently 

applied to the existing five amateur 

channels. Essentially, ARRL supports 

extending the provisions of footnote 

US23 and § 97.303(h) of the 

Commission’s rules that apply to the 

existing five amateur channels, 

including the 100 watt ERP limit, to the 

new allocation. Therefore, ARRL 

disagrees with applying the 15 W EIRP 

limit suggested in the WRC–15 Final 

Acts. While most commenters 

supported implementation of the ARRL 

Petition as filed, some commenters 

disagreed with various aspects of the 

ARRL Petition as addressed below. 

Some even argue that the entire 60 

meter band should be opened for 

amateur use at higher power because 

they are not aware of any complaints of 

harmful interference. Finally, the 

Commission noted that Canada has 

essentially implemented the same rules 

as ARRL has requested. 

The Commission proposes to modify 

footnote US23 and part 97 of its rules 


lotter on DSK11XQN23PROD with PROPOSALS1
67166 Federal Register / Vol. 88, No. 188 / Friday, September 29, 2023 / Proposed Rules 

to implement the new international 

allocation at 5351.5–5366.5 kHz, but 

also seeks comment on whether it 

should maintain the existing four 

channels at 5332, 5348, 5373, and 5405 

kHz that are outside of the new 

allocation. Specifically, the Commission 

proposes to make the following 

amendments to part 97 of the rules: (1) 

replace the five center frequencies with 

the 5351.5–5366.5 kHz band in 

§ 97.301(b) through (d) and 97.305(c); 

(2) simplify the frequency sharing 

requirements in § 97.303(h) by stating 

that amateur stations transmitting in the 

band must not cause harmful 

interference to, and must accept 

interference from, stations authorized by 

the United States and other nations in 

the fixed service; and other nations in 

the mobile except aeronautical mobile 

service; and (3) revise the emission 

standard in § 97.307(f)(14) by removing 

unneeded text, including the unneeded 

upper sideband and Morse telegraphy 

restrictions (as requested by ARRL in its 

petition). 

Under this proposal, amateurs would 

have access to a contiguous 15 

kilohertz-wide band. Allowing amateurs 

to use these internationally-harmonized 

frequencies could facilitate amateur 

communications across international 

borders. The Commission noted 

however, there is significant opposition 

from the amateur community regarding 

the removal of the four discrete 

channels at 5332, 5348, 5373, and 5405 

kHz from amateur use, as requested by 

NTIA. An argument could be made that 

amateur operations should remain on 

harmonized international frequencies 

because of the long-range propagation of 

these frequencies. Further, amateur 

licensees also have access to other high 

frequency (HF) bands at 3 and 7 MHz, 

so the Commission believed there 

should be sufficient spectrum options 

for amateur operations without 

deviating from the internationally 

harmonized spectrum. However, some 

commenters contended that the amateur 

community has been using the four 

discrete channels at 5332, 5348, 5373, 

and 5405 kHz that fall outside of the 

proposed band for some time and argue 

that these channels are important in 

responding to disasters. The 

Commission seeks comment on this 

issue and what spectrum in the 60 meter 

band should be made available for 

amateur use. 

Alternatively, the Commission seeks 

comment on whether the four discrete 

channels at 5332, 5348, 5373, and 5405 

kHz should be kept available for limited 

amateur use under certain conditions or 

only in response to disasters. For 

example, could the channels be 

authorized for amateur use during 

disasters as part of the Military 

Auxiliary Radio System (MARS) or 

SHAred RESources High Frequency 

Radio (SHARES) programs where 

participating amateur licensees can 

operate on Federal channels in 

coordination with the Department of 

Defense or Department of Homeland 

Security, respectively? Should the 

Commission permit amateur stations 

participating in established emergency 

communications programs such as the 

Amateur Radio Emergency Service 

(ARES) or the Radio Amateur Civil 

Emergency Service (RACES) to use the 

additional channels or operate at higher 

power during emergencies and drills? 

Could the discrete channels be 

maintained under lower power or under 

other conditions that might reduce their 

potential to interfere with primary 

allocation services in the band? If so, the 

Commission invites comment on 

whether the existing discrete channels 

should continue to be used for 

secondary amateur use and under what 

rules and conditions. 

While many amateur commenters 

argued they should be permitted access 

to more of the 60 meter band because 

they are not aware of any complaints of 

interference arising from their current 

operations, the Commission noted there 

are a variety of important non-Federal 

and Federal fixed and mobile except 

aeronautical mobile service operations 

in the band where even rare instances 

of interference could endanger public 

safety. Therefore, the Commission 

tentatively finds that the spectrum 

requirements for the amateur service in 

the 5005–5450 kHz band should be met 

by the WRC–15 amateur band and that 

only the four existing amateur channels 

at 5332, 5348, 5373, and 5405 kHz that 

are outside this band should be 

considered in this proceeding. 

Nevertheless, the Commission seeks 

comment on this idea. Commenters that 

support expanded access to the 60 meter 

band should provide information 

regarding how heavily the five amateur 

frequencies in the 5275–5450 kHz band 

are used and why additional amateur 

spectrum in this frequency range is 

needed if the Commission adopts the 

proposed allocation. 

Power. ARRL sought a maximum 

radiated power limit of 100 W ERP for 

the new secondary amateur allocation 

and to maintain the existing maximum 

radiated power limit of 100 W ERP for 

the existing discrete channels at 5332, 

5348, 5373, and 5405 kHz. ARRL argued 

that such an implementation would 

support amateurs engaged in emergency 

and disaster relief communications to 

more reliably, flexibly, and capably 

conduct those communications; that 

imposing a maximum radiated power 

limit of 15 W EIRP would render the 

band unsuitable for emergency and 

public service communications; that the 

lower power limit is insufficient to 

permit reliable communications on the 

paths that are most critical; and that this 

reduced radiated power limit is not 

necessary to protect primary services 

from interference. 

Harold Ross Lambert and Michael 

Goltz argued that the power limit 

should be increased to 500 W to deal 

with propagation challenges in disaster 

communications; and Milton K. Miller 

supports 500 W power with the use of 

more efficient antennas. Phillip Finkle 

urged for at least 200 W of power 

designated as output power instead of 

ERP because ERP is difficult to measure. 

Janis Carson initially expressed concern 

over allowing U.S. amateurs to operate 

at much higher powers than the 

international standard, suggesting a 

compromise power of 30 W because 

digital modes are very effective at lower 

power and world-wide communications 

can be achieved at lower power levels 

like 5 W. However, in later comments 

Ms. Carson supported the ARRL 

proposal to allow 100 W for ‘‘more 

reliable communications in an 

environment of high static crashes.’’ 

William Springer urged the adoption of 

the 15 W power limit in the WRC-15 

Final Acts because he contends that 

newer digital modes are more efficient, 

and so weaker signals are not an 

impediment to achieving 

communication. Finally Hugh Bahar 

cautioned that deviating from limits 

agreed to at the international level is 

unwise and could lead to other 

countries ignoring the standards and 

could be viewed as an act of bad faith. 

Several commenters also argued for 

more flexibility in the types of antennas 

permitted in the 60 meter band. Scott 

Wright and George Dominick contend 

that antennas with gain greater than 0 

dBi should be allowed since they are 

essential for efficient communications 

during an emergency. In contrast, 

Mathew Pitts does not support 

increasing the permitted antenna gain 

and contends the power should range 

between 15 and 30 W. 

The Commission seeks comment on 

the appropriate power limit for the new 

internationally harmonized amateur 

allocation and for the discrete channels 

if they are maintained for amateur use. 

The Commission tentatively concludes 

that limiting the radiated power of 

amateur stations to 15 W EIRP would 

reduce the potential of harmful 

interference to incumbent primary 

operations, while maintaining 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 88, No. 188 / Friday, September 29, 2023 / Proposed Rules 67167 

consistency with the power limits 

established internationally for amateur 

operations in this band. However, the 

majority of the amateur comments are 

opposed to lower power limits and 

neighboring countries in Region 2 

permit power levels higher than 15 W 

EIRP. The Commission agrees with 

certain commenters that the long-range 

propagation capabilities of these 

frequencies is likely to allow efficient 

communications at low-power levels, 

but there may be instances where more 

power is needed to deal with 

propagation challenges. 

The Commission acknowledges that 

valid arguments may exist for adopting 

power limits above 15 W up to 100 W. 

For example, § 2.106(b)(133)(ii) 

(footnote 5.133B or 5.133B), which 

addresses this international allocation, 

outlines a power limit of 20 W EIRP for 

Mexico and 25 W EIRP for all Latin 

American countries and for many 

Caribbean countries/territories. Further, 

a review of the Commission’s licensing 

database indicates other licenses with 

higher allocation status operating at 

power levels ranging from 15 W up to 

as high as 5000 W. Accordingly, the 

Commission seeks to build a more 

comprehensive record on the 

appropriate power limit for 60-meter 

band amateur operations. Interested 

parties seeking a power limit above the 

proposed 15 W EIRP limit should 

explain how much power would be 

appropriate, and how higher power 

limits would affect other operations in 

the 60-meter band? For example, should 

the Commission allow the higher power 

allowed in other countries in ITU 

Region 2, such as Mexico and most 

Caribbean countries? Should the 

Commission allow higher power during 

times of emergency drills/response or as 

part of programs where Amateur 

licensees support Federal emergency 

response? Should higher power only be 

permitted during disasters or drills 

supporting disaster relief? If, going 

forward, the discrete channels are 

permitted to be used by amateur 

operators under certain parameters or 

during disasters, what power limits 

should apply and when? What other 

conditions or considerations should be 

applied to amateur use of the 60 meter 

band? 

Further, the Commission seeks 

comment on how the limit should be 

specified in the rules. Specifically, 

should the power limit be defined in 

terms of EIRP to be consistent with the 

WRC–15 recommendation, or through 

some other means, such as ERP or 

transmitter output power? While some 

commenters argue that radiated power 

limits are difficult to calculate for 

certain types of antennas, the 

Commission finds that amateur 

licensees are supposed to study the 

radio arts and should be capable of 

determining their operating power. The 

Commission seeks comment on the pros 

and cons of various power limit 

alternatives and which method is best 

for the 60 meter band. If the 

Commission adopts a radiated power 

limit, it does not propose to adopt 

antenna limitations because a radiated 

power limit would ensure that excess 

power is not used, and flexibility in 

antenna choices may lead to spectrum 

efficiencies because the signal will 

propagate in its intended direction. 

Nevertheless, the Commission seeks 

comment on whether, and, if so what, 

antenna limitations are appropriate for 

amateur operations in this band using 

these different power limit 

measurements and how the 

Commission’s decision could affect how 

these frequencies would be used by the 

amateur community. 

Channelization. ARRL and several 

commenters argued that the new 

allocation should not designate subbands for various modes of operation to 

enable maximum flexibility to avoid 

interference with other operations. Janis 

Carson contended channelization is 

wasteful because narrowband modes 

can operate at less than three kilohertz 

and flexibility is need to address 

prevailing circumstances. She added 

that a maximum bandwidth of 500 Hertz 

should be allowed in the new 

contiguous allocation. Charles Powell 

supported the ARRL request and 

contends that amateur equipment is not 

designed to maintain a high level of 

frequency accuracy and that such a 

design change would make equipment 

prohibitively expensive. However, 

William Springer argued that the new 

allocation should be channelized into 

five 3 kilohertz channels to promote 

efficiency and avoid overlapping 

transmissions. Benjamin Russell also 

supported five discrete channels, but 

suggests creating ten overlapping 

channels for narrowband carrier wave 

(CW) use. Ronald F Henry contends that 

channelization would facilitate sharing 

with Federal users and, given there are 

several bands available for amateur use, 

the ‘‘60 Meter band must be set aside for 

emergency communications as the 

primary use and as such, channelization 

is desired to protect both the primary 

and secondary user.’’ 

The Commission proposes that the 

5351.5–5366.5 kHz band should not be 

channelized or have sub-bands. Due to 

the wide variety of potential 

applications and the need to protect 

other communications, dividing the 

band into channels may lead to 

inefficient spectrum use. However, the 

Commission agrees with commenters 

who state that some wideband digital 

emissions could create spectrum sharing 

problems, and so the Commission 

proposes a maximum emission 

bandwidth of 2.8 kilohertz for amateur 

operations in this band. The 

Commission seeks comment on this 

proposal and whether there are other 

limits or technical rule changes 

necessary to ensure reliable and 

efficient use of this band. 

Station Class and Permitted Uses. 

ARRL and certain other commenters 

stated that only amateurs with a General 

Class license or higher should be 

allowed to use the new allocation, 

because Technician Class license 

holders may not have the experience to 

operate consistent with the interference 

avoidance protocols needed for the 

band. William Springer opposed the 

allowance of CW transmissions in the 

band because he contends that they are 

outdated and inefficient, but supported 

the use of any commonly-available, 

unencrypted digital transmission mode 

limited by a maximum occupied 

bandwidth that fits within the channel. 

Scott Wright supported the allowance of 

CW, arguing that several CW emissions 

can fit within a small amount of 

bandwidth. Janis Carson and Hugh 

Bahar opposed the allowance of 

automatically controlled digital stations 

and wideband digital modes that could 

block the entire allocation and could 

cause interference without busy channel 

detection. In her reply comments, Ms. 

Carson added that the new allocation 

should be used for narrowband digital 

or CW and that the discrete channels, 

along with the one 3 kHz channel 

contained within the new allocation, 

could remain for use of single-side band 

(SSB) voice or wider digital modes. Ms. 

Carson also suggested not allowing any 

automatic store and forward email 

systems in the 60 meter band, claiming 

that these systems have a high potential 

to cause interference due to the ‘‘hidden 

transmitter’’ effect, where the offshore 

initiating station cannot hear a primary 

user in the skip zone of the shore based 

relay station. Finally, W. Lee McVey 

contended that the 60 meter band rules 

should ensure that only publicly 

documented digital codes operate in the 

band to prohibit encrypted 

communications. 

Consistent with the current amateur 

class requirements for the 60 meter band 

(see 47 CFR 97.301), the Commission 

proposes to permit amateurs holding a 

General Class license or higher to use 

the 5351.5–5366.5 kHz band. The 

Commission agrees with commenters 


lotter on DSK11XQN23PROD with PROPOSALS1
67168 Federal Register / Vol. 88, No. 188 / Friday, September 29, 2023 / Proposed Rules 

that the long-range propagation 

characteristics in the band combined 

with the need to protect important 

safety of life communications by Federal 

operations potentially requires a higher 

level of radio knowledge to ensure the 

spectrum is properly shared. The 

Commission seeks comment on this 

proposal. Further, if the Commission 

maintains the four existing discrete 

channels at 5332, 5348, 5373, and 5405 

kHz outside of the international 

allocation, the Commission proposes 

that those channels also be permitted for 

General Class licensees or higher. The 

Commission seeks comment on this 

proposal and other alternatives. For 

example, if the Commission adopts the 

new allocation and keeps the existing 

discrete channels, should different 

amateur classes be permitted on the new 

allocation versus the discrete channels? 

If the Commission allows station classes 

below General Class licensees to access 

the 60 meter band, what conditions 

should be applied? For example, should 

certain classes be permitted to operate 

in certain modes (i.e., voice vs. digital) 

or at certain times (e.g., only in response 

to a disaster)? Given the limited spectral 

resource at issue, commenters 

supporting more flexible use should 

support their comments with suggested 

safeguards or ideas on how the 

spectrum can be efficiently used 

without interfering with primary 

allocation operations. 

At this time, the Commission does not 

propose to preclude CW or any other 

radio technique currently permitted in 

the 60 meter band because the record is 

inconclusive on whether certain 

modulation methods should be 

prohibited. However, the Commission 

notes that the amateur rules generally 

preclude encrypted operations, and so 

seeks comment on whether the 60 meter 

band rules need to be clearer on what 

types of digital operations are permitted. 

As discussed above, the Commission 

proposes to limit the emission 

bandwidth to 2.8 kilohertz, which may 

limit some techniques. The Commission 

seeks comment on these proposals and 

encourages the amateur community to 

attempt to reach consensus on what 

radio techniques should be permitted, 

given the limited amount of spectrum 

available, the need to use this spectrum 

efficiently, and the importance of 

ensuring that the primary users are 

protected from harmful interference. 

2. Amateur Service in the 420–450 MHz 

Band 

Based on a request from NTIA, the 

Commission proposes to update the 

coordination and contact information in 

§ 2.106(c)(270) (footnote US270 or 

US270) for the areas wherein the peak 

envelope power of an amateur station 

operating in the 420–450 MHz (70 cm) 

band is generally limited to 50 watts, 

and to revise the cross reference to 

footnote US270 in § 97.313(f) of the 

rules. The Commission requests 

comment on these proposals. 

3. Maritime On-Board Communication 

Stations (457/467 MHz) 

The Commission proposes to revise 

§ 2.106(c)(288) (footnote US288 or 

US288) to make a limited number of 

narrowband channels from the 

international channel plan adopted at 

WRC–15 available for use by on-board 

communication stations. An on-board 

communication station is a lowpowered mobile station in the maritime 

mobile service used for internal 

communications on board a ship, or 

between a ship and its lifeboats and liferafts during lifeboat drills or operations, 

or for communication within a group of 

vessels being towed or pushed, as well 

as for line handling and mooring 

instructions. The Commission’s 

proposals are intended to benefit the 

maritime industry by making available a 

subset of the internationallyharmonized narrowband channels for 

on-board communication use while 

ships are in U.S. territorial waters. The 

Commission’s overarching goals in 

making these proposals are to minimize 

the potential for intermittent and 

harmful interference to stations in the 

land mobile and fixed services that 

operate on the same or adjacent 

frequencies to on-board communication 

stations and to promote more efficient 

and effective use of the available 

spectrum, while fully meeting the 

operational requirements of ship station 

licensees for on-board communication 

stations. 

Sections 2.106(c)(288) and 80.373(g) 

of the rules make seven internationallyharmonized frequencies in the 

457.5125–457.5875 MHz and 467.5125– 

467.5875 MHz bands (150 kilohertz) and 

five other frequencies available for use 

by on-board communication stations in 

U.S. territorial waters (275 kilohertz in 

total). Specifically, § 80.373(g)(1) states 

that the frequencies 457.525 MHz, 

457.550 MHz, 457.575 MHz, and 

457.600 MHz may be used by on-board 

repeater stations and by unpaired onboard mobile stations (i.e., singlefrequency simplex operation) and that 

four frequencies in the 467.7375– 

467.8375 MHz band (i.e., 467.750, 

467.775, 467.800, and 467.825 MHz) 

may be used by on-board mobile 

stations in two-frequency repeater 

systems. In addition, § 80.373(g)(2) 

states that, where needed, equipment 

designed for 12.5 kilohertz channel 

spacing using the additional frequencies 

457.5375 MHz, 457.5625 MHz, 467.5375 

MHz, and 467.5625 MHz (i.e., channels 

12, 14, 22, and 24) may be introduced 

for on-board communications; however, 

no use of these channels is currently 

authorized. 

WRC–15 revised the international 

channel plan for on-board 

communication stations to provide for 

6.25 kilohertz channels. This new 

channel plan, shown in table 1 below, 

specifies 40 frequencies that support the 

use of equipment designed to operate on 

25, 12.5, or 6.25 kilohertz channels. 

Channels 1, 2, 3, 12, 14, 22, and 24 as 

shown in Table 1 indicate the 

internationally-harmonized channels 

that are currently available for use 

under the Commission’s rules.

Federal Register / Vol. 88, No. 188 / Friday, September 29, 2023 / Proposed Rules 67169 

To permit the deployment of more 

spectrally efficient narrowband 

equipment, the Commission proposes to 

revise footnote US288 by authorizing 

on-board communication stations to use 

12.5 and 6.25 kilohertz channels in the 

territorial waters of the United States as 

described in the following paragraphs. 

First, the Commission proposes to 

revise footnote US288 to authorize: (1) 

nationwide use of channels 11–15, 

which are internationally-harmonized 

12.5 kilohertz channels, for on-board 

repeater stations and on-board mobile 

stations used for single-frequency 

simplex operation; (2) on-board mobile 

stations to operate nationwide on five 

non-harmonized frequencies that are 

10.225 megahertz higher in frequency 

than the center frequency of their 

associated on-board repeater stations 

(frequencies shown in table 2, below); 

and (3) on-board repeater stations to 

operate on channels 12 and 14 and 

associated on-board mobile stations 

operating on channels 22 and 24, 

respectively, in the Territorial Sea of the 

United States and at coastal ports and 

the inland ports of Baton Rouge, 

Houston, and Portland, and on the 

waterways and at other ports between 

these inland ports and the ocean. The 

Commission requests comment on these 

proposals. The Commission’s proposal 

would make two new frequencies 

(467.7625 and 467.7875 MHz) available 

for use by on-board communication 

stations and would authorize the use of 

eight existing frequencies with twice the 

power spectral density (PSD) in their 

narrower authorized bandwidth, which 

increases the potential for harmful 

interference to nearby stations of the 

fixed and land mobile services that also 

operate on these frequencies. PSD is 

defined as the ‘‘power of an emission in 

the frequency domain, such as in terms 

of ERP or EIRP, stated per unit 

bandwidth, e.g., watts/MHz.’’ 47 CFR 

22.99. Currently, the part 80 rules limit 

the ERP of on-board communication 

stations in the 456–468 MHz band to 2 

watts in a 25 kilohertz channel (80 mW/ 

kHz). If the Commission authorizes the 

same ERP in 6.25 kilohertz, then the 

PSD would double (160 mW/kHz), 

thereby increasing the potential for 

harmful interference over the signal’s 

bandwidth because the signal’s power is 

concentrated over a narrower 

bandwidth. The Commission intends to 

address the PSD issue in any subsequent 

service rules proceeding.

Second, the Commission proposes to 

revise footnote US288 to authorize onboard repeater stations and on-board 

mobile stations used for singlefrequency simplex operation to operate 

on the 6.25 kilohertz channels 102, 121, 

122, 141, and 142 and for on-board 

mobile stations operating with a 

repeater station to operate on the 6.25 

kilohertz channels 202, 221, 222, 241, 

and 242, respectively, in the Territorial 

Sea of the United States and at coastal 

ports and the inland ports of Baton 

Rouge, Houston, and Portland, and on 

the waterways and at other ports

between these inland ports and the 

ocean. The Commission requests 

comment on this proposal, noting that 

eight of these channels overlap the 12.5 

kilohertz channels that the Commission 

is proposing in the previous paragraph 

(i.e., channels 12, 14, 22, and 24) and 

that channels 102 and 202 are between 

low-power part 90 channels. The 

Commission requests comment on these 

proposals, noting that the use of 6.25 

kilohertz channels with center 

frequencies that are offset from the 

frequencies used by stations in the fixed 

and land mobile services by 6.25 

kilohertz are expected to enhance 

spectrum sharing. The Commission also 

solicits comment on whether it should 

authorize the use of channel pairs 121/ 

221 on those waterways in the 

contiguous United States that the 

Department of Transportation has 

designated as part of America’s Marine 

Highway. 

The Commission also proposes to 

revise the text of footnote US288 to state 

that, in the territorial waters of the 

United States, § 2.106(b)(287) (footnote 

5.287 or 5.287) applies, except that onboard communication stations must 

transmit only on the listed frequencies 

and must operate as specified herein. 

On-board repeater stations and mobile 

stations used for single-frequency 

simplex operation currently may 

transmit only in the band 457.5125– 

457.6125 MHz. The Commission 

proposes that the preferred frequencies 

for repeater systems would be 457.525 

MHz (channel 1 or 11), 457.5375 MHz 

(channel 12), 457.550 MHz (channel 2 

or 13), 457.5625 MHz (channel 14), 

457.575 MHz (channel 3 or 15), and 

457.600 MHz paired, respectively, with 

467.750 MHz, 467.7625 MHz, 467.775 

MHz, 467.7875 MHz, 467.800 MHz, and 

467.825 MHz; and the preferred 

frequencies for single-frequency 

operations would be those designated as 

channels 1–3, 11–15, and 121. Finally, 

the Commission proposes that use of 

channels 122, 141, and 142 and channel 

pairs 12/22, 14/24, 102/202, 121/221, 

122/222, 141/241, and 142/242 would 

be authorized at coastal ports and the 

inland ports of Houston, Baton Rouge, 

and Portland, and along the waterways 

and at other ports between these inland 

ports and the ocean; however, on-board 

communication stations would not be 

able to transmit on these channels while 

in port and not underway or preparing 

to get underway. The Commission seeks 

comment on these proposals. 

Finally, the Commission proposes to 

revise § 2.106(c)(287) (footnote US287 or 

US287) by allocating the 457.5125– 

457.6125 MHz, 467.512375–467.518625 

MHz, 467.55625–467.56875 MHz, 

467.53125–467.54375 MHz, and 

467.7375–467.8375 MHz bands (231.25 

kilohertz) to the maritime mobile 

service on a primary basis, by limiting 

the use of these allocations to on-board 

communication stations, and by stating 

that, in these frequency bands, stations 

in the fixed and land mobile services 

may not claim protection from 

interference caused by on-board 

communication stations operating in 

accordance with US288 and that onboard communication stations may not 

claim protection from stations in the 

fixed and land mobile services. 

Alternatively, the Commission requests 

comment on whether existing part 90 

Private Land Mobile and part 95 

Personal Radio Service licensees 

operating in the 456–470 MHz band 

should be afforded any protection from 

interference caused by on-board 

communication stations operating in 

accordance with US288. The 

Commission observes that the 456–470 

MHz band is allocated to the mobile 

service on a primary basis in all ITU 

Regions, and requests comment on the 

public interest benefits of both the 

Commission’s proposal and the 

alternative. 

4. Deletion of the Broadcasting Service 

From the 700 MHz Band 

The Commission proposes to delete 

the broadcasting service allocation in 

the 698–758 MHz, 775–788 MHz, and 

805–806 MHz bands from the nonFederal Table and to revise 

§ 2.106(d)(159) (footnote NG159 or 

NG159) by removing the reference to 

part 74, subpart G. Between 1998 and 

2010, the Commission transitioned the 

698–806 MHz (700 MHz) band from 

television broadcasting use (i.e., TV 

channels 52–69) to public safety and 

mobile broadband uses. Currently, the 

entire 700 MHz band is allocated to the 

fixed and mobile services on a primary 

basis, but the broadcasting service 

allocation still remains in the 698–758 

MHz, 775–788 MHz, and 805–806 MHz 

portions on a primary basis, and 

licensees in those bands have the 

flexibility to provide broadcast services, 

if they choose. The Commission 

requests comment on the Commission’s 

proposal. In the event that the 

Commission deletes the broadcast 

allocation as proposed, the Commission 

seeks comment on whether, and which, 

part 27 service rules should be modified 

to reflect the change (e.g., §§ 27.3 (Other 

Applicable Rule Parts), 27.4 (Terms and 

Definitions), 27.10 (Regulatory Status), 

27.13 (License Period), 27.50 (Power 

Limits and Duty Cycle), and 27.55 

(Power Strength Limits)). 

5. Deletion of Footnote NG155 

The Commission proposes to remove 

§ 2.106(d)(155) (footnote NG155 or 

NG155) from the rules because the 

frequencies and frequency bands to 

which it applies are not authorized in 

part 80 of the Commission’s rules. The 

ITU has identified the frequencies that 

can generally be used worldwide for 

intership communications. Thus, the 

Commission tentatively concludes that 

there is no need to specify any other 

frequencies for intership use. The 

Commission notes that, in the Second 

Report and Order in PR Docket No. 92– 

257 that added footnote NG155 to the 

Commission’s rules, the Commission 

declined to adopt the proposed rules for 

part 80 regarding maritime sharing of 

private land mobile radio frequencies 

for intership communications. The 

Commission requests comments on this 

proposal. 

C. Other Matters 

As a result of discussions regarding 

the protection of near-Earth operations 

of deep space missions, WRC–15 added 

a provision in Article 4 of the Radio 

Regulations (No. 4.24) to describe the 

use of space research service (deep 

space) allocations. Similarly, the 

Commission proposes to add a new 

paragraph to § 2.102 of the 

Commission’s rules to clarify that: 

‘‘Space research systems intended to 

operate in deep space may also use the 

space research service (deep space) 

allocations, with the same status as 

those allocations, when the spacecraft is 

near the Earth, such as during launch, 

early orbit, flying by the Earth and 

returning to the Earth.’’ The 

Commission requests comment on this 

proposal. 

The Commission proposes to amend 

§ 2.1(c) of the rules to add or revise the 

definitions for the terms 

‘‘meteorological aids land station,’’ 

‘‘meteorological aids mobile station,’’ 

and ‘‘coordinated universal time’’ in 

accordance with the WRC–15 adopted 

definitions. The Commission also 

proposes to add a definition for the term 

‘‘frequency band’’ based on that term’s 

ITU definition. The Commission seeks 

comment on these definitions. 

The Commission proposes to amend 

§ 2.105(d) of the rules by stating that the 

footnote references which appear in the 

United States Table below the allocated 

service or services apply to more than 

one of the allocated services, or to the 

whole of the allocation concerned, and 

that the footnote references which 

appear to the right of the name of a 

service are applicable only to that 

particular service. See the proposed 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 88, No. 188 / Friday, September 29, 2023 / Proposed Rules 67171 

rules for the proposed text of 

§ 2.105(d)(6) through (8), where the text 

in paragraph (d)(6) has been moved to 

paragraph (d)(8). 

In response to NTIA’s 

recommendation that the Commission 

add a subset of the international 

footnotes that identify spectrum for 

International Mobile 

Telecommunications (IMT) to the nonFederal Table, the Commission directed 

the Chief, Office of Engineering and 

Technology to maintain a ‘‘Mobile 

Broadband Spectrum in the United 

States’’ file on the ‘‘Radio Spectrum 

Allocation’’ web page. The Commission 

requests comment on whether this file 

meets the public’s needs. 

Digital Equity and Inclusion. Finally, 

the Commission, as part of its 

continuing effort to advance digital 

equity for all, including people of color, 

persons with disabilities, persons who 

live in rural or Tribal areas, and others 

who are or have been historically 

underserved, marginalized, or adversely 

affected by persistent poverty or 

inequality, invites comment on any 

equity-related considerations and 

benefits (if any) that may be associated 

with the proposals and issues discussed 

herein. Specifically, the Commission 

seeks comment on how its proposals 

may promote or inhibit advances in 

diversity, equity, inclusion, and 

accessibility, as well as the scope of the 

Commission’s relevant legal authority. 

Ordering Clauses 

Accordingly, it is ordered that, 

pursuant to sections 1, 4(i), 4(j), 7, 301, 

303(c), 303(f), and 303(r) of the 

Communications Act of 1934, as 

amended, 47 U.S.C. 151, 154(i), 154(j), 

157, 301, 303(c), 303(f), and 303(r), this

(23) US23 The band 5351.5–5366.5 

kHz (60 m band) is allocated to the 

amateur service on a secondary basis. 

Amateur service use of the 60 m band 

frequencies must meet the requirements 

in part 97 of these rules. Amateur 

operators using the data and RTTY 

emissions must exercise care to limit the 

length of transmissions so as to avoid 

causing harmful interference to Federal

and 1090 MHz for transponders on the 

condition that harmful interference will 

not be caused to the aeronautical 

radionavigation service (ARNS) or the 

aeronautical mobile (R) service 

(AM(R)S). These IFF systems will be 

evaluated on a case-by-case basis using 

DoD and FAA mutually agreed upon 

methodologies, technical criteria, and 

characteristics for calculating potential 

interference between ARNS/AM(R)S 

systems and systems used for military or 

other National defense IFF operations. 

This will include using DoD and FAA 

mutually agreed upon methodologies 

and criteria for considering the 

aggregation of civil and military systems 

in the 1030 and 1090 MHz bands in the 

evaluation.

output power of 125 watts, and new 

authorizations for stations, other than 

mobile stations, are subject to prior 

coordination by the applicant in the

may require the incumbent to cease 

operations, provided that the FSS 

licensee intends to turn on a system 

within interference range of the 

incumbent, as determined by TIA 

Bulletin 10–F or any standard successor. 

FSS licensee notification to the affected 

FS licensee must be in writing and must 

provide the incumbent with no less than 

six months to vacate the spectrum. After 

the six-month notice period has expired, 

the FS licensee must turn its license 

back into the Commission, unless the 

parties have entered into an agreement

(r) In the bands 17,700 to 19,700 and 

24,250 to 25,250 MHz: Operation of 

stations using frequencies in these 

bands is permitted to the extent 

specified in this paragraph (r). 

Licensees, except 24 GHz band 

licensees, may use either a two-way link 

or one frequency of a frequency pair for 

a one-way link and must coordinate 

proposed operations pursuant to the 

procedures required in § 101.103. The 

use of the band 18.3–19.3 GHz is limited 

to grandfathered stations. Licensees in 

the fixed-satellite service may require 

that licensees of grandfathered stations 

operating in the bands 18.3–19.3 GHz 

cease operations in accordance with the 

provisions in § 101.95. (Note that 

stations authorized as of September 9, 

1983, to use frequencies in the band 

17.7–19.7 GHz may, upon proper 

application, continue to be authorized 

for such operations, consistent with the 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 88, No. 188 / Friday, September 29, 2023 / Proposed Rules 67189 

above conditions related to the 18.3– 

19.3 GHz band.) Applicants for one-way 

spectrum from 17.7–18.3 GHz for 

multichannel video programming 

distribution are governed by paragraph 

(r)(6) of this section. Licensees are also 

allowed to use one-way (unpaired) 

channels in the 17.7–17.74 GHz subband to pair with other channels in the 

FS portions of the 18 GHz band where, 

for example, the return pair is already 

in use and therefore blocked or in TDD 

systems. Stations used for MVPD 

operations in the 17.7–17.8 GHz band 

must coordinate with the Federal 

Government before operating in the 

zones specified in § 1.924(e) of this 

chapter.
