Understanding 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 or Installer takes time to set up the NAV-7 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 NAV-7’s software comparing the Station
and Message Category information encoded into the message identifier (eg KA in
the diagram above) with the filter settings entered by the user during setup.
