[FoxHunt] Got a digital recorder, need a bit of a design

[R. Simmons]

This is being done on a routine basis in S. California :

http://www.thunter.org/geothunt/

http://www.silcom.com/~pelican2/PicoDopp/MICROHUNT.htm

http://www.silcom.com/~pelican2/PicoDopp/SQBX_MORE.html

 These transmitters have 60 second recording capacity, 16 selectable repeat
times from 15 seconds to 1/2 hour, 50 mW output on 2 meters and auxiliary
PTT and AUDIO outputs to drive an external TX, if desired. There's a 2 Watt
amplifier available also.

  I tried that with my first hunt last month, using an Alinco 570. It'll
also do
crossband-repeat, and I was feeding it in UHF and conducting the hunt
in VHF. :-)  The only problem with that was that I had to talk a lot! I'd
rather
make up a kit that'll do it automagically. :-)
