[wxsig] data string format

[Dave Barton]

Following the advice below, I upgraded the firmware and the station is now
transmitting packets (AI4GF-4).  I appreciate all the help!  Comsidering the
depths of my ignorance of electronics, it is very satisfying to have the
station working!

73, Dave

Sorry the links didn't come through correctly the first time.
The operations manual is here:

The latest firmware with instructions on how to load it are here:
