[aprssig] APRS adoption

[Steve Dimse]

And one bit of quick math - even if you round up Pete's number to 35k heard, ignore all the non-ham calls and assume everything is US (all major over-assumptions) with 720k US ham licenses you get an absolute max of 4.9% of US hams, which shows just how bogus that 28% was!

This assumes that beacons will make it to an I-Gate. But even if they all do not, it should provide a useful and valid data point that people don't have to argue about  :-)
