Sec. 74.582  Station identification.

    (a) Each aural broadcast STL or intercity relay station, when 
transmitting program material or information shall transmit station 
identification at the beginning and end of each period of operation, and 
hourly, as close to the hour as feasible, at a natural break in program 
offerings by one of the following means:

[[Page 410]]

    (1) Transmission of its own call sign by aural means or by automatic 
transmission of international Morse telegraphy.
    (2) Aural transmission of the call sign of the radio broadcast 
station with which it is licensed as an STL or intercity relay station.
    (3) Aural transmission of the call sign of the radio broadcast 
station whose signals are being relayed, or, when programs are obtained 
directly from network lines and relayed, the network identification.
    (b) Station identification transmissions during operation need not 
be made when to make such transmission would interrupt a single 
consecutive speech, play, religious service, symphony concert, or other 
such productions. In such cases, the identification transmission shall 
be made at the first interruption of the entertainment continuity and at 
the conclusion thereof.
    (c) Where more than one aural broadcast STL or intercity relay 
station is employed in an integrated relay system, the station at the 
point of origination may originate the transmission of the call signs of 
all of the stations in the relay system.
    (d) Aural broadcast microwave booster stations will be assigned 
individual call signs. However, station identification will be 
accomplished by the retransmission of identification as provided in 
paragraph (a) of this section.
    (e) Voice transmissions shall normally be employed for station 
identification. However, other methods of station identification may be 
permitted or required by the Commission.
