Hi,
My company -Brookhouse- makes NMEA multiplexers with a special feature
'editing on the fly', which allows the user to modify or convert NMEA
sentences real time, as they flow through the multiplexer.
We could take the radio call DSC sentence, lift out the lat/lon and MMSI
number and create a WPL (waypoint) NMEA sentence, whereby the MMSI number
could be used as the waypoint name.
By sending the WPL sentence to any chartplotter or navigation program, the
postion with MMSI number can be displayed in the electronic chart as a
waypoint, where one could subsequently navigate to.
Does that sound suitable for what you would like to achieve?
The 'programming' of the multiplexer is done using easy to use directives

If you can provide a few sample DSC sentences for testing, I'll be happy to
make the script file and post it here. Brookhouse multiplexer owners may be
interested to copy and paste the script and load it in their multiplexers
with a terminal program such as Hyperterminal.

I'm a member of the Coast Guard Auxiliary and had an interesting
question posed today. Is there a piece of commercially available
software that will translate the lat/long data transmitted from a DSC
radio call into a data stream that can be used to plot that lat/long
on a PC running something like MapSource?

Anyone got any ideas or information that I can track down? One of the
Auxiliary's missions is to provide Search and Rescue support to the
Active Coast Guard and something like this (that is also affordable)
would be a boon to our mission.

Thanks!

Ken
