Sec.  90.273   Availability and use of frequencies in the 421–430 MHz band.

   The frequency bands 422.1875425.4875 MHz and 427.1875429.9875 MHz are
   available for use in the Detroit, Michigan and Cleveland, Ohio areas. The
   bands 423.8125425.4875 MHz and 428.8125429.9875 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.
