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.
