[Code of Federal Regulations] [Title 47, Volume 2] [Revised as of October 1, 2007] From the U.S. Government Printing Office via GPO Access [CITE: 47CFR73.610] [Page 144-145] TITLE 47--TELECOMMUNICATION CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION (CONTINUED) PART 73_RADIO BROADCAST SERVICES--Table of Contents Subpart E_Television Broadcast Stations Sec. 73.610 Minimum distance separations between stations. (a) The provisions of this section relate to allotment separations and station separations. Petitions to amend the Table of Allotments (Sec. 73.606(b)) (other than those also expressly requesting amendment of this section or Sec. 73.609) will be dismissed and all applications for new TV broadcast stations or for changes in the transmitter sites of existing stations will not be accepted for filing if they fail to comply with the requirements specified in paragraphs (b), (c) and (d) of this section. Note: Licensees and permittees of television broadcast stations which were operating on April 14, 1952 pursuant to one or more separations below those set forth in Sec. 73.610 may continue to so operate, but in no event may they further reduce the separations below the minimum. As the existing separations of such stations are increased, the new separations will become the required minimum separations until separations are reached which comply with the requirements of Sec. 73.610. Thereafter, the provisions of said section shall be applicable. (b) Minimum co-channel allotment and station separations: (1) ---------------------------------------------------------------------------------------------------------------- Kilometers Zone --------------------------------------------- Channels 2-13 Channels 14-69 ---------------------------------------------------------------------------------------------------------------- I................................................................. 272.7 (169.5 miles) 248.6 (154.5 miles) II................................................................ 304.9 (189.5 miles) 280.8 (174.5 miles) III............................................................... 353.2 (219.5 miles) 329.0 (204.5 miles) ---------------------------------------------------------------------------------------------------------------- (2) The minimum co-channel distance separation between a station in one zone and a station in another zone shall be that of the zone requiring the lower separation. (c) Minimum allotment and station adjacent channel separations applicable to all zones: (1) Channels 2-13 95.7 kilometers (59.5 miles). Channels 14-69 87.7 kilometers (54.5 miles). (2) Due to the frequency spacing which exists between Channels 4 and 5, between Channels 6 and 7, and between Channels 13 and 14, the minimum adjacent channel separations specified above shall not be applicable to these pairs of channels (see Sec. 73.603(a)). (d) In addition to the requirements of paragraphs (a), (b) and (c) of this section, the minimum assignment and station separations between stations on Channels 14-69, inclusive, as set forth in Table II of Sec. 73.698 must be met in either rule-making proceedings looking towards the amendment of the Table of Assignments (Sec. 73.606(b)) or in licensing proceedings. No channel listed in column (1) of Table II of Sec. 73.698 will be assigned to any city, and no application for an authorization to operate on such a channel will be granted, unless the distance separations indicated at the top of columns (2) through (7), inclusive, are met with respect to each of the channels listed in those columns and parallel with the channel in column (1). (e) The zone in which the transmitter of a television station is located or proposed to be located determines the applicable rules with respect to co-channel distance separations where the transmitter is located in a different zone from that in which the channel to be employed is located. [[Page 145]] (f) The distances listed below apply only to allotments and assignments on Channel 6 (82-88 MHz). The Commission will not accept petitions to amend the Table of Allotments, applications for new stations, or applications to change the channel or location of existing assignments where the following minimum distances (between transmitter sites, in kilometers) from any FM Channel 253 allotment or assignment are not met: Minimum Distance Separation from FM Channel 253 (98.5 MHz) ------------------------------------------------------------------------ TV Zones II Fm Class TV Zone I & III ------------------------------------------------------------------------ A............................................. 17 22 B1............................................ 19 23 B............................................. 22 26 C3............................................ 19 23 C2............................................ 22 26 C1............................................ 29 33 C............................................. 36 41 ------------------------------------------------------------------------ (Secs. 4, 5, 303, 48 Stat., as amended, 1066, 1068, 1082 (47 U.S.C. 154, 155, 303)) [28 FR 13660, Dec. 14, 1963, as amended at 37 FR 25842, Dec. 5, 1972; 44 FR 65765, Nov. 15, 1979; 47 FR 35990, Aug. 18, 1982; 50 FR 23698, June 5, 1985; 51 FR 44070, Dec. 8, 1986; 54 FR 14964, Apr. 14, 1989; 54 FR 16368, Apr. 24, 1989; 54 FR 35340, Aug. 25, 1989]
