  § 74.502   Frequency assignment.

   (a) Except as provided in NG30, broadcast auxiliary stations licensed
   as of November 21, 1984, to operate in the band 942-944 MHz1 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 § 101.105(c)(2).

   1Note: 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 § § 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.

   frequency pair for a one-way link.

   (2) [Reserved]

   (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 § 101.105(a), (b), and (c) of
   this chapter and the frequency usage coordination procedures of
   § 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 § 2.106 of this chapter.
