Sec.  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.
