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, and one instance each of SlowJT9 and
JS8Call. I'm told that a number of ops do this with other brands of rigs
to allow the decoders to rx simultaneously, and to tx with any of them
without any reconfig necessary (though obviously only one app can be
used to transmit at any given time). At this point, I have all the
decoders running simultaneously and successfully decoding incoming
signals. Now I'm just working on getting VOX mode working to transmit.
As things stand now, when I click Tune or enable transmit in WSJT-X, the
Windows audio system indicates that audio is going out to the USB Codec.
To answer your questions, nothing is plugged into the Line In on the K3S
rear panel. When I started working on this, the K3S was in split mode
with Data B selected. In order to get into Data A, I first needed to
disable split mode. I then enabled VOX. The levels you mentioned all
appear to be set appropriately.
Now, if I click Tune or enable transmit in WSJT-X, the K3S reenables
split mode and switches to Data B. The red transmit light never comes on.
Undoubtedly there's another setting I need to do something with?
Thanks and 73,
Frank K6FOD

Line Gain on the radio is typically is set for 30 to 40 using the MIC
control on the front panel. And with the others, set the ALC
bargraph to show 4 to 5 bars and then set the PWR value on the radio
to that which you desire to operate. The PWR slider on WSJT-X is set
in the upper 3/4 of the scale, depending on SPKR level set on the
computer. I use 30 to 35 for SPKR level on the computer.

Frank,
My read of your comments is that it is all OK. If you are getting
power out, you're on the air. Nothing to do but operate. Pick some
strong station calling CQ and give him a call. And, see what happens.
There should be nothing else on the rig to fiddle with at this time.

Thanks. After I set mine up the same, when I press Tune or transmit
in WSJT-X I can see audio going out to the USB Codec output in the
Windows audio system. However, no sign of any action on the K3S.
Besides toggling VOX on with the button at the upper left of the
K3(s)'s front panel, is there anything else you need to set on the
rig to make this work?

Frank,
Do use the K3 description on the radio page. This will allow
the software to change the radio frequency as you change bands and
modes. Once, you are on the band, frequency is a matter of the tone
that is generated. And, VOX does the rest. Pretty straight forward.
It all becomes really clear after your 3rd or so contact. :-) Have
fun.

Barry,
Thanks. I was specifically wondering about entries on WSJT-X's
Settings > Radio page:
-- At the top of the page, is anything filled in for "Rig"?
-- The lefthand side of the page has the heading "CAT Control," so
is anything entered here (serial port, baud rate, data/stop bits,
DTR/RTS, etc)?
-- On the righthand side of the page, I assume "VOX" is selected
as PTT method. What choices are selected for Mode and for Split
Operation?
Thanks again,
Frank

Frank,
I use VOX for all of my digital operation to include AFSK,
FT8, and FT4. I really haven't done anything to the default
setting that came with the radio. I just set the line in to 20
and adjust the power slider in WSJT-X to get the 4 bars with 5th
flickering on the K3s's ALC readout. Nothing fancy! One caution:
watch your PA temperature. It will definitely rise.

I've successfully used WSJT-X with my K3S for a fairly long
time, using a single USB cable for both audio transfer and CAT
control.
Currently I'm interested in trying VOX in order to enable
running multiple instances of WSJT-X simultaneously on the same
band (JT9 and WSPR on 474.2 kHz, if it's of any interest). Could
anyone who is using VOX for WSJT-X with a K3/K3S tell me how
they have the Settings > Radio pane in WSJT-X configured? I can
probably stumble my way through, but some pointers would
undoubtedly make faster progress.
Thanks and 73,
Frank K6FOD
