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.
