§ 90.273 Availability and use of frequencies in the 421-430 MHz band.
The frequency bands 422.1875-425.4875 MHz and 427.1875-429.9875 MHz are
available for use in the Detroit, Michigan and Cleveland, Ohio areas.
The bands 423.8125-425.4875 MHz and 428.8125-429.9875 MHz are available
for use in the Buffalo, New York area. Sections 90.273 through 90.281
address the specific rules applicable to these bands. Use of these
bands is also subject to the general technical standards and
application procedures contained in other subparts of part 90. The
technical standards applicable in this band are the same as those
contained in subpart I of part 90 for the 450-470 MHz band. Private
land mobile use of these frequencies is subject to accepting any
interference from Federal Government radiolocation operations.
(a) The following tables list frequencies available for assignment in
the Public Safety and Industrial/Business Pools as indicated. In the
tables, the Public Safety Pool frequencies are denoted as "PS" and the
Industrial/Business Pool frequencies are denoted as "IB." The
frequencies 422.19375 MHz through 424.99375 MHz are paired with
frequencies 427.19375 MHz through 429.99375 MHz, respectively. Only the
lower half of each frequency pair, available for base station
operation, is listed in the tables. Corresponding mobile and control
station frequencies are 5 MHz higher than the base station frequency.
The frequencies 425.000 through 425.48125 are unpaired and are
available for either single frequency dispatch or paging operations.
