For ships operating in coastal areas, Marine Safety Information (MSI)
is disseminated using the international NAVTEX system transmitting on
518 kHz (SITOR-B)
NAVTEX is an internationally standard method of receiving notices.
The service uses a single frequency with transmissions from nominated
stations within each NAVAREA being arranged on a time-sharing basis to
eliminate mutual interference. All necessary information is contained
in each transmission. The power of each transmitter is regulated so as
to avoid the possibility of interference between transmissions.
Each NAVTEX message broadcast contains a four-character header (B1 to B4)
describing:
First character (B1) = station ID
The transmitter indentification character (B1) is a single unique letter
wich is allocated to each transmitter. It is used to indentify the
broadcasts wich are to be accepted by the receiver and those wich are to
be rejected. In order to avoid erroneous reception from two stations having
the same (B1) character, it is necessary to ensure that such stations have
a large geographical separation. NAVTEX transmissions have a designed range
of about 400 nautical miles.
Second character (B2) = message content (subject indicator characters)
The subject indicator character is used by the receiver to indentify
different classes of messages (see below) The indicator is also used to
reject messages concerning certain optional subjects wich are not required
by the ship (e.g. OMEGA msg if the ship is not fitted with an OMEGA receiver)
Third and forth character = message serial number
SAMPLE NAVTEX MESSAGE:
______________ Beginn of new message
| __________ Geographic indentifier (station ID)
| | _________ Subject indentifier (message content)

always receive the most vital information.
B F and G are normally not used in the U.S. Since the NWS service
normally includes meteorological warnings in forecast messages,
meteorological warnings are broadcast using the subject indicator
character E. USCG District Broadcast Notices to Mariners affecting
ships outside the line of demarcation, and inside the line of
demarcation in areas where deep draft vessels operate, use the
subject indicator character A.
