  § 80.111   Radiotelephone operating procedures for coast stations.

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

   (a) Limitations on calling. (1) Except when transmitting a general call to
   all stations for announcing or preceding the transmission of distress,
   urgency,  or safety messages, a coast station must call the particular
   station(s) with which it intends to communicate.

   (2) Coast stations must call ship stations by voice unless it is known that
   the  particular  ship  station may be contacted by other means such as
   automatic actuation of a selective ringing or calling device.

   (3) Coast stations may be authorized emission for selective calling on each
   working frequency.

   (4) Calling a particular station must not continue for more than one minute
   in each instance. If the called station does not reply, that station must
   not again be called for two minutes. When a called station does not reply to
   a call sent three times at intervals of two minutes, the calling must cease
   for fifteen minutes. However, if harmful interference will not be caused to
   other communications in progress, the call may be repeated after three
   minutes.

   (5) A coast station must not attempt to communicate with a ship station that
   has specifically called another coast station until it becomes evident that
   the called station does not answer, or that communication between the ship
   station  and  the  called  station  cannot  be  carried  on because of
   unsatisfactory operating conditions.

   (6) Calls to establish communication must be initiated on an available
   common working frequency when such a frequency exists and it is known that
   the  called  ship maintains a simultaneous watch on the common working
   frequency and the appropriate calling frequency(ies).

   (b) Time limitation on calling frequency. Transmissions by coast stations on
   2182  kHz  or  156.800  MHz  must be minimized and any one exchange of
   communications must not exceed one minute in duration.

   (c) Change to working frequency. After establishing communications with
   another station by call and reply on 2182 kHz or 156.800 MHz coast stations
   must  change  to an authorized working channel for the transmission of
   messages.

   (d) Use of busy signal. A coast station, when communicating with a ship
   station which transmits to the coast station on a radio channel which is a
   different channel from that used by the coast station for transmission, may
   transmit a “busy” signal whenever transmission from the ship station is
   being received. The characteristics of the “busy” signal are contained in
   § 80.74.
