NAVTEX/AMTEX Operation
To enter the NAVTEX/AMTEX mode, simply type NAVTEX from the command
prompt and press return. At this point, you will see nothing on the terminal until
a valid NAVTEX message is received.
To exit the NAVTEX mode and return to the command prompt,
type <Ctrl+C> X. (Do not hold the Control key when you type the X.)
Before entering the NAVTEX mode (while you still have the command prompt),
you may specify which stations you wish to receive using the NAVSTA com
-
mand. For instance, if I wish to copy AMTEX bulletins issued by ARRL, but do
not want those from other stations, I type NAVSTA A at the command prompt. To
monitor all stations, simply type NAVSTA ALL.
You may also specify which message classes you wish to receive by using the
NAVMSG command. If you wanted the Satellite bulletins and DX bulletins, you
would type NAVMSG ES and press return. If you eliminate message classes A,
B, or D from the list of valid message classes, you will receive a WARNING
message from the KAM’98 since the NAVTEX specification requires that these
classes must be printed at least once.
