§  80.519   Station identification.

   (a) Stations must identify transmissions by announcing in the English
   language the station's assigned call sign. In lieu of the
   identification of the station by voice, the official call sign may be
   transmitted by tone-modulated telegraphy in international Morse Code
   manually or by means of an automatic device approved by the Commission.
   Transmissions on the navigation frequency (156.650 MHz) by stations on
   drawbridges may be identified by use of the name of the bridge in lieu
   of the call sign. Identification must be made:

   (1) At the beginning and end of each exchange of communications and;

   (2) At intervals not exceeding 15 minutes whenever transmissions or
   communications are sustained for more than 15 minutes.

   (b) Marine utility stations, private coast stations, and associated
   hand-held radios, when exchanging communications, may be identified by
   a unit identifier in lieu of the call sign. Identification by
   transmission of the assigned call sign must be at the end of the
   exchange or at least once every 15 minutes.
