§  80.453   Scope of communications.

   Public coast stations provide ship/shore radiotelephone and
   radiotelegraph services.

   (a) Public coast stations are authorized to communicate:

   (1) With any ship or aircraft station operating in the maritime mobile
   service, for the transmission or reception of safety communication;

   (2) With any land station to exchange safety communications to or from
   a ship or aircraft station;

   (3) With Government and non-Government ship and aircraft stations to
   exchange public correspondence;

   (4) With units on land in accordance with § 80.123.

   designated station at a remote fixed location where other communication
   facilities are not available.

   (c) Public coast stations are authorized to transmit meteorological and
   navigational information of benefit to mariners.

   (d) Each public coast telegraphy station is authorized to communicate
   with other public coast telegraphy stations to exchange message traffic
   destined to or originated at mobile stations:

   (1) To exchange operating signals, brief service messages or safety
   communication;

   (2) To exchange message traffic destined for a mobile station when the
   coast station initially concerned is unable to communicate directly
   with the mobile station;

   (3) In the Great Lakes region, to exchange message traffic originated
   at a mobile station when the use of available point-to-point
   communication facilities would delay the delivery of such message
   traffic;

   (4) Utilization of radiotelegraphy must not incur additional charges or
   replace available point-to-point communication facilities;

   (5) Only authorized working frequencies within the band 415 kHz to 5000
   kHz must be employed for communications between coast stations;

   (6) Harmful interference must not be caused to communication between
   mobile stations and coast stations or between mobile stations.
