§ 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
(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
(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.
(e) Transmission from an earth station of an unmodulated carrier at a
power level sufficient to saturate a satellite transponder is
prohibited, except as consented to by the space station licensee to
determine transponder performance characteristics.
