That was why my original approach to the rino was to
decode the transmission directly.  I captured the
waveforms, and we had it mostly decoded, but then
the effort shifted to the simple xastir approach and
we lost the momentum.  But the fact that the RINO 
uses a receiver that is typically 7 dB worse than
a typical HAM receiver would double the useful
range in an APRS system.

I wish someone would take that on....  boy would
it help APRS at SAR etc...
