4.1About Navtex Messages

4.1.1Message categories

Navtex stations throughout the world provide mariners with weather and navigational navtex messages. These messages carry a four character header code which identifies transmitting station, category of message, and message number, numbered from 00 to 99. Message number 00 is reserved for important emergency messages. The categories of messages available in the navtex system are as below.

A: Coastal navigational warning	H: Loran message
B: Meteorlogical warning	I: Omega message
C: Ice report	J: Differential Omega message
D: Search and Rescue Alert	K: Other electronic navigator system message
E: Meteorological forecast	L: Navarea warnings
F: Pilot message	V to Y: No category allocated
G: Decca message	Z: QRU (no message on hand)

The user may select which message categories to receive and the stations from which to receive them.

Note: It is recommended to minimally receive categories A, B, D and L because they are important for navigation.

4.1.2Receiving navtex messages

To receive navtex messages, set the receive mode for “navtex only” or “fax(timer) & navtex”, referring to paragraph 1.1.3 for the procedure.
