   (1) When one or more individual transmitters are to be operated by a
   licensee as a base station or as a fixed station at unspecified or
   temporary locations for indeterminate periods, such transmitters may be
   considered to comprise a single station intended to be operated at
   temporary locations.

   (2) The application must specify the general geographic area within
   which the operation will be confined. The area may be specified as a
   city, a county or counties, a state or states or other definable
   geographic area such as a specified radius around a particular city or
   known geographic site.

   days must be accompanied by evidence of frequency coordination, except
   that applications for operation at temporary locations exceeding 180
   days by applicants using 220-222 MHz spectrum for geophysical telemetry
   operations need not be accompanied by evidence of frequency
   coordination.

   (b) When any unit or units of a base station or fixed station which are
   authorized for operation at temporary locations actually remain or are
   intended to remain at the same location for more than 1 year, an
   application for a separate authorization specifying the fixed location
   shall be made as soon as possible, but not later than 30 days after the
   expiration of the 1-year period.

   (c) The provisions of this section do not apply to the 4940-4990 MHz
