                             ORDER


   Adopted:  July 31, 1997                   Released: August 13, 1997


By the Commission:

     1.  By this Order, the Commission adopts revisions to 47 C.F.R.  73.207(b) of the
Commission's rules with respect to minimum distance separations between U.S. FM assignments
and allotments and Mexican assignments and allotments.  These revised spacings were
promulgated in the Agreement Between the Government of the United States of America and the
Government of the United Mexican States Relating to the FM Broadcasting Service in the Band
88-108 MHz,  dated August 11, 1992  (hereafter "Agreement").  The rule revisions adopted
herein conform the rule to the Agreement.  

     2.  These changes will have no adverse effect on any existing or presently proposed FM
broadcast station.  In all cases, the minimum required separations specified in the Agreement do
not exceed, and in most cases, are less than the separations presently specified in Table C of
Section 73.207(b)(3).   Moreover, as a matter of practice, since late August 1992 the staff has
employed the Agreement minimum distance separations without adversely affecting
broadcasters.  Consequently,  the revisions are noncontroversial, and prior notice and comment
proceedings are neither necessary nor required.  See 5 U.S.C.  553(b)(3)(B); and 47 C.F.R. 
1.412(c).

     3.   Accordingly, IT IS ORDERED, that pursuant to the authority contained in Sections
4(i) and 303 of the Communications Act of 1934, as amended,  47 C.F.R.  73.207(b) IS
AMENDED as set forth in Appendix A, below.

     4.  IT IS FURTHER ORDERED, that the rules adopted herein will become effective
upon publication in the Federal Register.

     5.  Pursuant to the Regulatory Flexibility Act, 5 U.S.C.  601 et seq., as amended by the
Contract With America Advancement Act of 1996,  ("CWAAA"),  5 U.S.C.  606(b), Pub. L.
No. 104-121, 110 Stat. 847 (1996), the Commission certifies that no significant impact on a
substantial number of small entities will result from adoption of this Order. .

   73.207 Minumum distance separation between stations

                             *****

and Class B-C1 Relations ]  

(b)(3)  Under the 1992 Mexico-United States FM Broadcasting Agreement, 
domestic U.S. assignments or allotments within 320 kilometers (199 miles) of the common
border must be separated from Mexican assignments or allotments by not less than the distances
given in Table C, which follows.  When applying Table C, 

     (i)     U.S. or Mexican assignments or allotments which have been notified internationally
as Class A are limited to a maximum of 3.0 kW ERP at 100 meters HAAT, or the equivalent;

     (ii)     U.S. or Mexican assignments or allotments which have been notified
internationally as Class AA are limited to a maximum of 6.0 kW ERP at 100 meters HAAT, or
the equivalent;

     (iii)     U.S. Class C3 assignments or allotments are considered Class B1;

     (iv)     U.S. Class C2 assignments or allotments are considered Class B; and
     
     (v)      Class C1 assignments or allotments assume maximum facilities of 100 kW ERP at
300 meters HAAT.  However, U.S. Class C1 stations may not, in any event, exceed the domestic
U.S. limit of 100 kW ERP at 299 meters HAAT, or the equivalent.
