I have a 5W
APRS (VHF) tracking unit with a ducky in my aircraft and it reaches
about 60 miles direct to my iGate. Not bad.

60 miles coverage on the ground? to what elevation of a receiving
antenna? Details.. details..

As for APRS.. while I applaud it, the "catch" is that you have to have a
HAM radio licence and ham radio equipment to utilize the existing VHF
packet network.
