[aprssig] Interesting commercial tracker device

It'll be interesting to see how well it's able to get positions to 
Globalstar at 400 mW with that rather pathetic-looking antenna.  And 
here's an interesting quote:

"SPOT says that the actual transmit power is comparable to the 
Globalstar sat phones, but that SPOT uses twice the spectrum, using 
spread-spectrum technology, for better performance."

Whatever happened to Eb/N0?
