And I was SO looking forward to your version of Knight of the Round Table,

I think this is a "Holy Grail" kind of quest (no, not the ones with African
or European Swallows).  The quest to get working GMSK 9600 APRS on a RFM-22B
is one worthy of the attention of some of the really smart folks around
here.  RFM-22-equipped trackers with $30 GPS modules, powered by 4 AA
batteries with a $5 Atmega chip driving the whole thing, would be a huge win
for race tracking, parade management, scout management, etc.  I'm using the
RFM22 for another (semi-commercial) project, but I'll be happy to contribute
anything I learn.  If someone is really willing to take on figuring out a
two-way 9600bps APRS Tracker for 430MHz, I'd be willing to front a couple of
modules and an arduino.
