Wow, neat info!

Looks like CALL,LAT,LONG,SYMBOL,CSE,SPEED, then STATUS TEXT?
My guess is that CSE is stored as 1-to-8 for the cardinatl
points of the compass. The above examples have no speed? Not
sure about that.
But if this is true, then SOMONE should write a PIC processor to
parse out of theese packets, any FREQUNCY info an either display
it or something. I wonder if you SELECT one of these stations
on the LIST and hit OK, will it output the above data for that
If so, then a PIC couild then parse out the frequency info and
put it back into side B and there you have one-button TUNE
capability to someone that is transmitting his frequency.! The
format for FREQUENCY has been established as the first 10 bytes
of the STATUS text field if available.
