  §  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.
