§ 90.559 Station Identification.
(a) Conventional systems of communication shall be identified in
accordance with existing regulations governing such matters.
(b) Trunked systems of communication, except as noted in paragraph (c)
of this section, shall be identified through the use of an automatic
device which transmits the call sign of the base station facility at 30
minute intervals. Such station identification shall be made on the
lowest frequency in the base station trunk group assigned the licensee.
Should this frequency be in use at the time station identification is
required, such identification may be made at the termination of the
communication in progress on this frequency. Identification may be made
by voice or International Morse Code. When the call sign is transmitted
in International Morse Code, it must be at a rate of between 15 to 20
words per minute and by means of tone modulation of the transmitter,
the tone frequency being between 800 and 1000 hertz.
(c) Stations operating in the 769-775/799-805 MHz band that are
licensed on an exclusive basis, and normally employ digital signals for
the transmission of data, text, control codes, or digitized voice may
also be identified by digital transmission of the call sign. A licensee
that identifies its station in this manner must provide the Commission,
upon its request, information sufficient to decode the digital
transmission and ascertain the call sign transmitted.
