[aprssig] FW: Animal tracking using GPS+UHF

[Joe Della Barba]

Well Alinco did make a UHF version of the same credit card radio. They 
still do make 2M.70CM versions of it. The TinyTrack at least can switch 
the transmitter on X seconds before it beacons, so that would save some 
batteries. Too bad the pockettracker died :(
A kangaroo is a pretty big animal. I bet you could get a whole digi 
setup in the pouch!
