Sec. 74.482  Station identification.

    (a) Each remote pickup broadcast station shall be identified by the 
transmission of the assigned station or system call sign, or by the call 
sign of the associated broadcast station. For systems, the licensee 
(including a part 73-only licensee where operation takes place pursuant 
to Sec. 74.24) shall assign a unit designator to each station in the 
system. The call sign (and unit designator, where appropriate) shall be 
transmitted at the beginning and end of each period of operation. A 
period of operation may consist of a single continuous transmission, or 
a series of intermittent transmissions pertaining to a single event.
    (b) In cases where a period of operation is of more than one hour 
duration identification of remote pickup broadcast stations 
participating in the

[[Page 401]]

operation shall be made at approximately one-hour intervals. 
Identification transmissions during operation need not be made when to 
make such transmissions would interrupt a single consecutive speech, 
play, religious service, symphony, concert, or any type of production. 
In such cases, the identification transmissions shall be made at the 
first interruption in the program continuity and at the conclusion 
thereof. Hourly identification may be accomplished either by 
transmission of the station or system call sign and unit designator 
assigned to the individual station or identification of an associated 
broadcasting station or network with which the remote pickup broadcast 
station is being used.
    (c) In cases where an automatic relay station is a part of the 
circuit, the call sign of the relay transmitter may be transmitted 
automatically by the relay transmitter or by the remote pickup broadcast 
base or mobile station that actuates the automatic relay station.
    (d) Automatically activated equipment may be used to transmit 
station identification in International Morse Code, provided that the 
modulation tone is 1200 Hz&177;800 Hz, the level of modulation of 
the identification signal is maintained at 40%&177;10%, and that 
the code transmission rate is maintained between 20 and 25 words per 
minute.
    (e) For stations using the F3Y emission, identification shall be 
transmitted in the unscrambled analog (F3) mode or in International 
Morse Code pursuant to the provisions of (d) of this section at 
intervals not to exceed 15 minutes. For purposes of rule enforcement, 
all licensees using F3Y emissions shall provide, upon request by the 
Commission, a full and complete description of the encoding methodology 
they currently use.

    Note: Stations are encouraged to identify using their associated 
part 73 station call sign.
