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)


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

D    Search and rescue information

E    Meteorological forecasts

F    Pilot service

G    DECCA messages

H    LORAN C messages

Z    No message on hand (QRU)

Note: A B and D are non-rejectable to ensure that ships using NAVTEX

      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.
