Sec.  90.137   Applications for operation at temporary locations.

   (a) An application for authority to operate a base or a fixed transmitter at
   temporary locations shall be filed in accordance with  Sec. 1.931 of this chapter
   and the following:

   (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.

   (3) Applications for operation at temporary locations exceeding 180 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 band.
