Don,
Thanks for the comment.
CAT has always been the PTT method I've used with WSJT-X, and it's been
very successful. It would normally be my first choice.
However, I just ran across this interesting configuration that some
number of 630m ops are using, using other brands of rigs. Since all of
the digital modes on 630m are based off the same frequency of 474.2 kHz,
they set their rigs to that frequency and then use VOX control to allow
several decoders on the same PC to rx simultaneously, and tx one at a
time without any reconfiguration. I gather this couldn't be done if the
decoder apps used CAT, as only one app can have CAT control of the rig
at any time.
So I wanted to give this a try. So far I have several decoders receiving
simultaneously from the K3S, and it's nice to have JT9, WSPR, SlowJT9
and JS8 all being decoded at the same time. I'm just having challenges
getting transmitting to work with VOX. I know the PC is sending audio
out the USB Codec when I hit the Tune button in WSJT-X, and I know VOX
works on my K3S because I use it for CW. Just trying to knit the final
details together.

Frank,
Although several others have had success with VOX, I find the most
reliable is to use PTT via CAT command. Set it in the application and
you will have no problem.
If your problem is related to audio levels, refer to my website
www.w3fpr.com. Scroll the left column to the last article and click
to open the page. No matter whether you are operating from the
transverter mode or the normal antenna, you must have 4 bars solid
with the 5th bar flashing on the ALC meter.

Bob,
First, let me back up and say that I'm operating with the K3S in
transverter mode on 630m with an external power amp. I've
successfully used CAT control with WSJT-X on a MacBook Pro to tx/rx
JT9 and WSPR. My objective now is to use the K3S in VOX mode with a
Windows 10 desktop running two instances of WSJT-X,
