Subpart N_Operating Requirements
Sec. 90.425 Station identification.
Stations licensed under this part shall transmit identification in
accordance with the following provisions:
(a
) Identification procedure. Except as provided for in paragraphs
(d) and (e) of this section,
each station or system shall be identified
by the transmission of the assigned call sign during each transmission
or exchange of transmissions, or once each 15 minutes (30 minutes in the
Public Safety Pool) during periods of continuous operation. The call
sign shall be transmitted by voice in the English language or by
International Morse Code in accordance with paragraph (b) of this
section. If the station is employing either analog or digital voice
scrambling, or non-voice emission, transmission of the required
identification shall be in the unscrambled mode using A3E, F3E or G3E
emission, or International Morse, with all encoding disabled.
Permissible alternative identification procedures are as follows:
(1) A mobile relay stations call sign may be used to identify the
associated control and mobile stations, except in the Public Safety Pool
where the stations operate on frequencies below 450 MHz. Alternatively,
a base station (including a mobile relay station) which is controlled by
radio may be identified by the transmission of the call sign of the
station at which communications originate.
(2) One or more fixed relay stations may be identified by the
transmission of the call signs of the stations at which the
communications originate.
(3) When a mobile station transmits on a different frequency than
its associated base station, the assigned call sign of either the mobile
station or the base station may be transmitted. Further, a single mobile
unit in the licensee's authorized geographic area of operation may
transmit station identification on behalf of any other operating mobile
units in the fleet.
(4) Use of an identifier other than the assigned call sign. (i) In
the Public Safety Pool, mobile units licensed to a governmental entity
and which operate on frequencies above 30 MHz may use an identifier
which contains, at a minimum, the name of the licensee if the licensee
maintains at the station a list of the special identifiers to be used by
the mobile units.
