§  74.682   Station identification.

   (a) Each television broadcast auxiliary station operating with a
   transmitter output power of 1 watt or more must, when actually
   transmitting programs, 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 visual or aural means or by
   automatic transmission in international Morse telegraphy.

   (2) Visual or aural transmission of the call sign of the TV broadcast
   station with which it is licensed as an auxiliary.

   (3) Visual or aural transmission of the call sign of the TV broadcast
   station whose signals are being relayed or, where programs are obtained
   directly from network lines and relayed, the network identification.

   (b) 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 any type of production.
   In such cases, the identification transmission shall be made at the
   first interruption of the entertainment continuity and at the
   conclusion thereof.

   (c) During occasions when a television pickup station is being used to
   deliver program material for network distribution it may transmit the
   network identification in lieu of its own or associated TV station call
   sign during the actual program pickup. However, if it is providing the
   network feed through its own associated TV broadcast station it shall
   perform the station identification required by paragraph (a) of this
   section at the beginning and end of each period of operation.

   (d) A period of operation is defined as a single uninterrupted
   transmission or a series of intermittent transmissions from a single
   location or continuous or intermittent transmission from a television
   pickup station covering a single event from various locations, within a
   single broadcast day.

   (e) Regardless of the method used for station identification it shall
   be performed in a manner conducive to prompt association of the signal
   source with the responsible licensee. In exercising the discretion
   provided by this rule, licensees are expected to act in a responsible
   manner to assure that result.

   (f) TV microwave boosters 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.
