NAVTEX message headers
At the beginning of each NAVTEX message there is a message header which
identifies the source and nature of message, time and date of reception, received
frequency and error rate.
For example:
KA59 14:16
19-Jul 518 0%
In the Message Index display only the message identifier is visible.
It is recommended that the user takes time to set up the SMARTFIND GMDSS
NAVTEX to filter out those stations and message categories that are not required. In
this way the display is kept uncluttered; only those messages that are required will be
visible.
Messages are selected for display by the SMARTFIND GMDSS NAVTEX’s software
comparing the Station and Message Category information encoded into the message
identifier (e.g. KA in the diagram above) with the filter settings entered by the user
during setup.
