§  73.507   Minimum distance separations between stations.

   (a) Minimum distance separations. No application for a new station, or
   change in channel or transmitter site or increase in facilities of an
   existing station, will be granted unless the proposed facilities will
   be located so as to meet the adjacent channel distance separations
   specified in § 73.207(a) for the class of station involved with respect
   to assignment on Channels 221, 222, and 223 listed in § 73.201 (except
   where in the case of an existing station the proposed facilities fall
   within the provisions of § 73.207(b)), or where a Class D station is
   changing frequency to comply with the requirements of § 73.512.

   (b) Stations authorized as of September 10, 1962, which do not meet the
   requirements of paragraph (a) of this section and § 73.511, may continue
   to operate as authorized; but any application to change facilities will
   be subject to the provisions of this section.

   (c)(1) Stations separated in frequency by 10.6 or 10.8 MHz (53 or 54
   channels) from allotments or assignments on non-reserved channels will
   not be authorized unless they conform to the separations in Table A
   given in § 73.207.

   (2) Under the United States-Mexican FM Broadcasting Agreement, for
   stations and assignments differing in frequency by 10.6 to 10.8 MHz (53
   or 54 channels), U.S. noncommercial educational FM allotments and
   assignments must meet the separations given in Table C of § 73.207 to
   Mexican allotments or assignments in the border area.
