§ 80.102   Radiotelephone station identification.

   This section applies to all stations using telephony which are subject to
   this part.

   (a) Except as provided in paragraphs (d) and (e) of this section, stations
   must give the call sign in English. Identification must be made:

   (1) At the beginning and end of each communication with any other station.

   (2) At 15 minute intervals when transmission is sustained for more than 15
   minutes.  When public correspondence is being exchanged with a ship or
   aircraft station, the identification may be deferred until the completion of
   the communications.

   (b) Private coast stations located at drawbridges and transmitting on the
   navigation frequency 156.650 MHz may identify by use of the name of the
   bridge in lieu of the call sign.

   (c)  Ship stations transmitting on any authorized VHF bridge-to-bridge
   channel may be identified by the name of the ship in lieu of the call sign.

   (d) Ship stations operating in a vessel traffic service system or on a
   waterway  under  the  control of a U.S. Government agency or a foreign
   authoriy,  when  communicating with such an agency or authority may be
   identified by the name of the ship in lieu of the call sign, or as directed
   by the agency or foreign authority.

   (e) Voice traffic in the INMARSAT system is closed to other parties except
   the two stations involved and the identification is done automatically with
   the establishment of the call. Therefore, it is not necessary for these
   stations to identify themselves periodically during the communication. For
   terrestrial systems using DSC to establish radiotelephone communications,
   the identification is made at the beginning of the call. In these cases,
   both parties must identify themselves by ship name, call sign or MMSI at
   least once every 15 minutes during radiotelephone communications.

   (f) VHF public coast stations licensed to serve a predetermined geographic
   service area are not required to provide station identification under this
   section. A site-based VHF public coast station may identify by means of the
   approximate geographic location of the station or the area it serves when it
   is the only VHF public coast station serving the location or there will be
   no conflict with the identification of any other station.
