Sec. 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.
