§  87.41   Frequencies.

   (a) Applicant responsibilities. The applicant must propose frequencies
   to be used by the station consistent with the applicant's eligibility,
   the proposed operation and the frequencies available for assignment.
   Applicants must cooperate in the selection and use of frequencies in
   order to minimize interference and obtain the most effective use of
   stations. See subpart E and the appropriate subpart applicable to the
   class of station being considered.

   (b) Licensing limitations. Frequencies are available for assignment to
   stations on a shared basis only and will not be assigned for the
   exclusive use of any licensee. The use of any assigned frequency may be
   restricted to one or more geographical areas.

   (c) Government frequencies. Frequencies allocated exclusively to
   federal government radio stations may be licensed. The applicant for a
   government frequency must provide a satisfactory showing that such
   assignment is required for inter-communication with government stations
   or required for coordination with activities of the federal government.
   The Commission will coordinate with the appropriate government agency
   before a government frequency is assigned.

   (d) Assigned frequency. The frequency coinciding with the center of an
   authorized bandwidth of emission must be specified as the assigned
   frequency. For single sideband emission, the carrier frequency must
   also be specified.
