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:

   (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.
