Every Navtex message is preceded by a four character header B(1) B(2)B(3)B(4). B(1) is an alpha character identifying the station, and B(2) is an alpha character used to identify the subject of the message. Receivers use these characters to reject messages from stations or concerning subjects of no interest to the user.
Each Navtex message has an area code (see map), denoting which transmitter it came from. You can generally tell the receiver which stations you want to receive and which to filter out, as a means of reducing useless and irrelevant information which would otherwise clutter up the receiver.
National Navtex services usually use 490kHz. This may be received automatically on some dual-channel receivers but might have to be selected on others. Older sets usually only have the 518kHz channel.
In particular, it’s important to understand the shorthand used when Navtex information is transmitted. Line 1 - ZCZC indicates the start of a message. F indicates the geographic area and A60 indicates the ‘subject’ of the message.
This is the Navtex message reference followed by the message itself. Last Line - NNNN indicates the end of message. In addition, various countries also have specific uses for subjects listed above.
