[Dx4win] PSK31 - how to transmit?

[David M. Monfried]

Searched the archives but could not find the answer to this simple(?)
problem - I'm unable to key the IC7800 using the PSK31 function in DX4WIN
7.05.04. I am able to decode signals, but can't figure out what I'm doing
wrong on transmit. Here's the set-up:

 

IC7800 + Navigator (in file/Preferences/Control, tried both Default Sound
Card and Cards 0 and 1 in PSK Sound Card).

 

Presently control radio via com port 7; tried Stop Radio and using com port
7 ( PSK31 window/ Alt+S /TX/com 7, then tried PTT and VOX).  Nothing.

 

Control SteppIr antenna via Remote jack on IC7800.  

 

Successfully use HRD with DM780 - but give up DX4WIN control of rig to HRD
when I want to operate RTTY or PSK31.that's why I'd like to get the PSK31
function going on DX4WIN.

 

I assume I'm missing something elementary - a cable connection or software
setting. If I have to add a PTT connection, I don't see where it would
terminate on the radio.

 

Any help would be much appreciated. Thank you.
