[Packet] FWD: PDA set up?

[john]

I have a program (not by me!)  running that  copies  PSK31 and CW on a 
PocketPC PDA..... it  works just by pointing the PDA mic to the speaker of 
the receiver. It works remarkably well, but I realize this is neither the 
mode nor the duplex functionality you're looking for.

Good luck!
