Sec.  74.1283   Station identification.

   (a) The call sign of an FM broadcast translator station will consist of the
   initial letter K or W followed by the channel number assigned to the
   translator and two letters. The use of the initial letter will generally
   conform to the pattern used in the broadcast service. The two letter
   combinations following the channel number will be assigned in order and
   requests for the assignment of particular combinations of letters will not
   be considered.

   (b) The call sign of an FM booster station will consist of the call sign of
   the primary station followed by the letters “FM” and the number of the
   booster station being authorized, e.g., WFCCFM–1.

   (c) A translator station authorized under this subpart shall be identified
   by one of the following methods.

   (1) By arranging for the primary station whose station is being rebroadcast
   to identify the translator station by call sign and location. Three such
   identifications shall be made during each day: once between 7 a.m. and 9
   a.m., once between 12:55 p.m. and 1:05 p.m. and once between 4 p.m. and 6
   p.m. Stations which do not begin their broadcast before 9 a.m. shall make
   their first identification at the beginning of their broadcast days. The
   licensee of an FM translator whose station identification is made by the
   primary station must arrange for the primary station licensee to keep in its
   file, and to make available to FCC personnel, the translator's call letters
   and location, giving the name, address and telephone number of the licensee
   or his service representative to be contacted in the event of malfunction of
   the translator. It shall be the responsibility of the translator licensee to
   furnish current information to the primary station licensee for this
   purpose.

   (2) By transmitting the call sign in International Morse Code at least once
   each hour. Transmitters of FM broadcast translator stations of more than 1
   watt transmitter output power must be equipped with an automatic keying
   device that will transmit the call sign at least once each hour, unless
   there is in effect a firm agreement with the translator's primary station as
   provided in  Sec. 74.1283(c)(1) of this section. Transmission of the call sign
   can be accomplished by:

   (i) Frequency shifting key; the carrier shift shall not be less than 5 kHz
   nor greater than 25 kHz.

   (ii) Amplitude modulation of the FM carrier of at least 30 percent
   modulation. The audio frequency tone use shall not be within 200 hertz of
   the Emergency Broadcast System Attention signal alerting frequencies.

   (d) FM broadcast booster stations shall be identified by their primary
   stations, by the broadcasting of the primary station's call signs and
   location, in accordance with the provisions of  Sec. 73.1201 of this chapter.

   (e) The Commission may, in its discretion, specify other methods of
   identification.
