Gummit buys this one. If the damned Coast Guard had one when those kids
died on S/V "Morning Dew", there would have been no question WHERE the kid
was screaming for help and the stupid CG watchstander MIGHT not have
thought it was a hoax...saving lives.

Here, build your own! $169, complete. Use an array of Metz half-wave
marine antennas instead of the 1/4 wave verticals stuck to the car because
your boat doesn't have a ground plane....Hams use them for "fox hunts"
where someone hides with a walkie and the hams run ragged across the county
trying to find him. When I'm the fox, I park under the big powerlines
which throws them off great!...(c;
