Almost all GPSs have anchor watch alarms and radars have range

or MOB statement??

Yes, it's called a laptop, and you can connect MASSIVE speakers to
it!

Some how keeping a laptop running 24 hours a day for 3 or 4 days just
to monitor for alarm sentences when the job could be done with a
fairly simple circuit drawing only a few milliwatts seems more than a
little bit wastefull. Also the laptop may be subject to the
idiosyncrasies of Windoze.

I'm sure you are right, but picking up a GPS circuit is more than my limited
knowledge of electronics can manage, and as my laptop is connected to the
gps most of the time, it seems an easy shortcut.
