§  25.275   Particulars of operation.

   (a) Radio station authorizations issued under this part will normally
   specify only the frequency bands authorized for transmission and/or
   reception of the station.

   (b) When authorized frequency bands are specified in the station
   authorization, the licensee is authorized to transmit any number of
   r.f. carriers on any discrete frequencies within an authorized
   frequency band in accordance with the other terms and conditions of the
   authorization and the requirements of this part. Specific r.f. carrier
   frequencies within the authorized frequency band shall be selected by
   the licensee to avoid unacceptable levels of interference being caused
   to other earth, space or terrestrial stations. Any coordination
   agreements, both domestic and international, concerning specific
   frequency usage constraints, including non-use of any particular
   frequencies within the frequency bands listed in the station
   authorization, are considered to be conditions of the station
   authorization.

   (c) A license for a transmitting earth station will normally specify
   only the r.f. carriers having the highest e.i.r.p. density, the
   narrowest bandwidth, and the largest bandwidth authorized for
   transmission from that station. Unless otherwise specified in the
   station authorization, the licensee is authorized to transmit any other
   type of carrier not specifically listed which does not exceed the
   highest e.i.r.p., e.i.r.p. density and bandwidth prescribed for any
   listed emission.

   (d) Only the most sensitive emission(s) for which protection is being
   afforded from interference in the authorized receive frequency band(s)
   will be specified in the station authorization.
