§  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.
