Almost all GPSs have anchor watch alarms and radars have range alarms but
they all put out a whimpy little beep. Is there a device that monitors
the
NMEA data streams (from say a multiplexer) and make a noise that will get
your attention when it sees an alarm or MOB statement??

Hi,
Talking about "decent" multiplexers, all our NMEA multiplexers have
"automatic GPS back-up switching" (plus many other NMEA sentence management
features). Read about it he
http://brookhouseonline.com/gps_backup_switching.htm . I have been
playing with the idea to add a buzzer to warn the user when it switches to
the backup GPS. As the "no GPS data" detection is already present, this is
very simple to do. If there is sufficient interest, we'll include it as a
standard feature. If you want it NOW, we'll add a buzzer to the present
model for a small charge if you decide to buy one.
