Rick,
While I know you know what you're doing, it seems excessively complex to
this reader.
The DAD box "needs" PTT off of the LOT port to operate properly. It tells
the DAD when to switch things automatically from one rig to the other (like
headphones etc.) in addition to causing the target radio to actually
transmit.
I think you would have much more success if you looked at this from a "only
use PTT" perspective instead which would be a controlled PTT of your
transmitters, instead of VEX.
In addition, if you are doing SO2R, you only need one sound card. By rule,
you can only transmit one signal at a time anyway. The DXD switches it from
one radio to the other following the radio a/b toggle on the LPT port.
The audio chain should be: Mic--> Soundcard --> DXD --> Radio mic input (A
or B depending on the LPT radio select pin).
73,
Bob W5OV

Subject: [WriteLog] Fwd: WL Soundcard Mixer FRUSTRATION
Many TNX to all for the replies and suggestions.
Yes, I had been using a Stereo to Mono adaptor at the external VOX operated
audio card input. I am not going to do a full automation thing this time,
as am QRX for (hopefully) Wayne to add my ALT + K "Unlimited SSB Messages"
enhancement.
3 trips to into town (Radio Shack) later, and falling off the wagon buying a
pack of cigarettes, I ended up with a 1/8" stereo to mono "Y" connector
which I thought my solve the problem...and to route only one side of the
audio to the radio with the audio interface.
Unfortunately, l still can't get to the bottom of why WL is still sending
some kind of PTT signal via the DXD to either radio when I push an SSB
message key where the audio is NOT connected to the other radio via a 2nd
outboard sound card (they didn't get the parts to fix my 2nd card in time).
I know it doesn't seem to make any sense, but the key I use to hot-switch
between radios also sends my callsign. if I'm on the Radio with no audio
card interface but want to snag someone on the other radio which does have
the audio card, then it makes perfect sense.
Any ideas of what on earth is triggering the PTT when I clearly selected
"NO" for PTT on COMM Port? I even unchecked the CW only/RTS box on the
Ports dialog box. My outboard sound cards are VOX operated...I don't want
ANY "PTT" type operation from WL. I even turned off the PTT switch on the
DXD, but in any case still need to resolve this PTT issue before I get the
2nd audio card back and installed. I simply do not want PTT under any
circumstances, but can't figure out how to axe it in WL.
Tnx again to all for the suggestions.
73...
Rick, K6VVA
