4.1 About Navtex Messages
4.1.1 Message 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.
4.1.2 Receiving 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.
