FYI,

     The 3.5mm Data Jack is an "HF" data jack.   I will work for receive on
any band but it will not work for transmit on 2m & 70cm.  Use the DIN VHF
DATA connector to transmit above 6 Meters.  Watch which pin you use as the
1200 and 9600 bps pins operate very differently.

I discoverd this the hard way while trying to get PSK-31working.  After
messing with it for a couple of hours on 70cm when I switched to 20m the
interface worked great.
I can not run all Digital modes on HF and 1200 & 9600 mps Packet on 2m &
70cm.
