[aprssig] APRS and RF data modules

If someone wants to do the RF design, I'll contribute the tracker circuit.
And maybe handle some production and distribution, for that matter, if it
can be made cheap enough.  No sense in selling something more expensive than
a DJ-S11T.

I have thought about building a circuit similar to the Ramsey. but add
support for a PIC so it would be a useful 2m tracking beacon.  Maybe a
DC-DC converter, so the thing would run off a single 1.5V AA lithium?
It would need 3 or 5 volts for the PIC and 9 or 12 for the transmitter.
  I think maxim has a beastie that does both.  Yet another project for
my copious spare time...
