[aprssig] Re: Rush Limbaugh talking about APRS / GPS

[KC2MMi]

The hams who invented *what* concept aren't getting royalties from it?

The hams who invented GPS?

Or the hams who invented vehicle tracking?

I didn't think hams claimed to have invented either of those. APRS is only
one of many implementations of tracking systems. GPS is only one means of
determining positions.
