## GOVRNMENT OR NON-GOVERNMENT?

## Excerpt from COMMUNICATIONS ACT OF 1934 (entire Act can be found at: 'http://www.fcc.gov/Reports/1934new.pdf'):SEC. 305. [47 U.S.C. 305] GOVERNMENT‐OWNED STATIONS.(a) Radio stations belonging to and operated by the United States shall not be subject to the provisions of sections 301 and 303 of this Act. All such Government stations shall use such frequencies as shall be assigned to each or to each class by the President. All such stations, except stations on board naval and other Government vessels while at sea or beyond the limits of the continental United States, when transmitting any radio communication or signal other than a communication or signal relating to Government business, shall conform to such rules and regulations designed to prevent interference with other radio stations and the rights of others as the Commission may prescribe.(b) All stations owned and operated by the United States, except mobile stations of the Army of the United States, and all other stations on land and sea, shall have special call letters designated by the Commission.(c) The provisions of sections 301 and 303 of this Act notwithstanding, the President may, provided he determines it to be consistent with and in the interest of national security, authorize a foreign government, under such terms and conditions as he may prescribe, to construct and operate at the seat of government of the United States a low‐power radio station in the fixed service at or near thesite of the embassy or legation of such foreign government for transmission of its messages to points outside the United States, but only (1) where he determines that the authorization would be consistent with the national interest of the United States and (2) where such foreign government has provided reciprocal privileges to the United States to construct and operate radio stations within territories subject to its jurisdiction. Foreign government stations authorized pursuant to the provisions of this subsection shall conform to such rules and regulations as the President may prescribe. The authorization of such stations, and the renewal, modification, suspension, revocation, or other termination of such authority shall be in accordance with such procedures as may be established by the President and shall not be subject to the other provisions of this Act or of the Administrative Procedure Act.*****************

## EXCERPT FROM NTIA MANUAL8.2.17 Determining Whether a Station is a Government Station  1. The following guidelines are to assist in the determination of whether or not a station belongs to and is operated by the United States as specified in Section 305(a) of the Communications Act of 1934 : 	a. The department or agency concerned should be able to exercise effective control over the radio equipment and its operation; and 	b. The department or agency concerned assumes responsibility for contractor compliance with Executive Branch, departmental, or agency instructions and limitations regarding use of the equipment and ensures that such instructions and limitations are met when operating under the authority of an Executive Branch frequency authorization to the department or agency; and 	c. The station should be operated by an employee of the department or agency or by a person who operates under the control of the department or agency on a contractual or cooperative agreement basis, and who is under supervision of the department or agency sufficient to ensure that Executive Branch, departmental, or agency instructions and limitations are met. 2. It is recognized that a Government agency may make a contract arrangement for maintenance or operation of a radio station under its control without diminishing the effective control of, or responsibility for, such station, provided the appropriate limitations or requirements are specified. 3. Since the foregoing may not cover every case, or where there may be doubt, the determination will be made by the department or agency concerned after consultation with the NTIA/ FCC as appropriate.

## US310--In the band 14.896-15.121 GHz, non-Federal government space stations in the space research service may be authorized on a secondary basis to transmit to Tracking and Data Relay Satellites subject to such conditions as may be applied on a case-by-case basis. Such transmissions shall not cause harmful interference to authorized Federal government stations. The power flux density at the earth's surface from such non-Government stations shall not exceed 138 to 148 dBW/m2/4kHz, depending on the angle of arrival, in accordance with Recommendation ITU-Recommendation 510-1.
