Yeah, at lower data rates I've seen ranges of at least 100 miles at 1/2 
watt on 2 meters.  The test units are currently running at 4800 baud, 
which will sacrifice some margin, but they've also got some error 
correction capability which ought to help make up for it.

I was going to get an Az/El rotor system, but it turns out to be cheaper 
to make my assistant stand on the roof and hold the antenna.  =]
