Sec. 74.982  Station identification.

    (a) Call signs for instructional television fixed stations will 
consist of three letters and three digits pursuant to the provisions of 
Sec. 2.302 of this chapter relating to fixed stations.
    (b) Except as otherwise provided in paragraphs (c) and (d) of this 
section, each instructional television fixed station shall transmit its 
call sign at the beginning and end of each period of operation and, 
during operation, on the hour. Visual or aural transmissions shall be 
employed.
    (c) The hourly station identification announcement during operation 
may be deferred if it would interrupt a single consecutive 
demonstration, lecture, or other similar discourse or otherwise impair 
the continuity of a program in progress. In such cases the station 
identification announcement shall be made at the first normal break in 
the continuity of the program.
    (d) In cases where an instructional television fixed station is

other station operated by the same licensee, its call sign shall be 
announced by the originating station at the times and in the manner 
prescribed in paragraph (b) of this section.
    (e) Where an instructional television fixed station is operating as 
a relay for signals originating at a station operated by some other 
licensee, its call sign may be transmitted by the originating station, 
if suitable arrangements can be made with the other licensee, or means 
shall be provided for the transmission of the call sign by the relay 
transmitter itself. Low power relay stations, authorized by 
Sec. 74.950(f)(4) will not be assigned individual call signs. Station 
identification will be accomplished by the retransmission of the call 
sign of the primary station.
    (f) Temporary fixed ITFS stations shall identify with the call sign 
of the primary station and a temporary fixed identifier.
