§  22.813   Technical channel pair assignment criteria.

   The rules in this section establish technical assignment criteria for
   the channel pairs listed in § 22.805. These criteria are intended to
   provide substantial service volumes over areas that have significant
   local and regional general aviation activity, while maintaining the
   continuous nationwide in-route coverage of the original geographical
   layout.

   (a) Distance separation for co-channel ground stations. The FCC may
   grant an application requesting assignment of a communication channel
   pair to a proposed ground transmitter only if the proposed antenna
   location is at least 800 kilometers (497 miles) from the antenna
   location of the nearest co-channel ground transmitter in the United
   States, its territories and possessions; and 1000 kilometers (621
   miles) from the antenna location of the nearest co-channel ground
   transmitter in Canada.

   (b) Dispersion. The FCC may grant an application requesting assignment
   of a communication channel pair to a proposed ground transmitter only
   if there are no more than five different communication channel pairs
   already assigned to ground transmitters with antenna locations within a
   320 kilometer (199 mile) radius of the proposed antenna location.
