Sec.  74.502   Frequency assignment.

   (a) Except as provided in US 302, broadcast auxiliary stations licensed as
   of November 21, 1984, to operate in the band 942–944 MHz^1 may continue to
   operate on a co-equal primary basis to other stations and services operating
   in the band in accordance with the Table of Frequency Allocations. These
   stations will be protected from possible interference caused by new users of
   the band by the technical standards specified in  Sec. 101.105(c)(2).

   ^1 Note:In addition to this band, stations in Puerto Rico may continue to be
   authorized on 942.5, 943.0, 943.5, 944.0 MHz in the band 942–944 MHz on a
   primary basis to stations and services operating in accordance with the
   Table of Frequency Allocations.

   (b) The frequency band 944–952 MHz is available for assignment to aural STL
   and  ICR stations. One or more of the following 25 kHz segments may be
   stacked to form a channel which may be assigned with a maximum authorized
   bandwidth of 300 kHz except as noted in the following Table. The channel,
   will be assigned by its center frequency, channel bandwidth, and emission
   designator.  The  following  frequencies are the centers of individual
   segments. When stacking an even number of segments, the center frequency
   specified will deviate from the following frequencies in that it should
   correspond to the actual center of stacked channels. When stacking an odd
   number of channels, the center frequency specified will correspond to one of
   the following frequencies.

   (1) A single broadcast station may be authorized up to a maximum of twenty
   segments (500 kHz total bandwidth) for transmission of program material
   between a single origin and one or more designations. The station may lease
   excess capacity for broadcast and other uses on a secondary basis, subject
   to  availability of spectrum for broadcast use. However, an FM station
   licensed for twelve or fewer segments (300 kHz total bandwidth) or an AM
   station licensed for eight or fewer segments (200 kHz total bandwidth) may
   lease excess capacity for broadcast and other uses on a primary basis.

   (2) An applicant (new or modification of existing license) may assume the
   cost  of  replacement of one or more existing licensees equipment with
   narrowband equipment of comparable capabilities and quality in order to make
   available spectrum for its facilities. Existing licensees must accept such
   replacement without cost to them except upon a showing that the replacement
   equipment does not meet the capability or quality requirements.

   (c) Aural broadcast STL and intercity relay stations that were licensed or
   had applications pending before the Commission as of September 18, 1998 may
   continue those operations in the band 18,760–18,820 and 19,100–19,160 MHz on
   a shared co-primary basis with other services under parts 21, 25, and 101 of
   this chapter until June 8, 2010. Prior to June 8, 2010, such stations are
   subject to relocation by licensees in the fixed-satellite service. Such
   relocation is subject to the provisions of  Sec.  Sec. 101.85 through 101.97 of this
   chapter. After June 8, 2010, such operations are not entitled to protection
   from fixed-satellite service operations and must not cause unacceptable
   interference to fixed-satellite service station operations. No applications
   for new licenses will be accepted in these bands after June 8, 2000.

   (d) For the coordination of all frequency assignments for fixed stations
   above  944  MHz,  for  each  frequency authorized under this part, the
   interference  protection criteria in  Sec. 101.105(a), (b), and (c) of this
   chapter and the frequency usage coordination procedures of  Sec. 101.103(d) of
   this chapter will apply.

   (e) The use of the frequencies listed in paragraph (b) of this section by
   aural broadcast intercity relay stations is subject to the condition that no
   harmful interference is caused to other classes of stations operating in
   accordance with the Table of Frequency Allocations contained in  Sec. 2.106 of
   this chapter.
