Sec. 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 Sec. 73.207(a) for the class of station involved with 
respect to assignment on Channels 221, 222, and 223 listed in 
Sec. 73.201 (except where in the case of an existing station the 
proposed facilities fall within the provisions of Sec. 73.207(b)), or 
where a Class D station is changing frequency to comply with the 
requirements of Sec. 73.512.
    (b) Stations authorized as of September 10, 1962, which do not meet 
the requirements of paragraph (a) of this section and Sec. 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 Sec. 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 Sec. 73.207 to 
Mexican allotments or assignments in the border area.
