Paul,
I understand you're not wanting to use the PC Sound Card for Digi, as
too often Windows sounds get into the transmission. FWIW .. you really
don't need a Signalink with the KX3, but since you already have it I can
understand your using it. In future if you want to take the KX3 for
digi, just get an inexpensive USB soundcard (Under $15 at Amazon) and
use standard audio cables, and the KXUSB cables for CAT control.
I regularly use my KX3 (and K2/100) for WSJT-X, and have found that
using the KXUSB cable for CAT is much more reliable than VOX.
The main thing is the Windows device settings. Right click on the
'sound' or 'speaker' icon at the bottom right, select SOUNDS from the
menu. Go to the Recording tab, and select the Input Mic: USB Codec
device, and click on properties. On that device's LEVELS tab, right
click on the slider, and change the setting from PERCENTAGE to
DECIBELS. Then adjust the slider to show 0 dB. Do the same with the
Speakers: USB Codec device.
Then adjust the KX3 AF/RF-SQL to show about 30 dB on the WSJT-X left
hand meter on an empty band. On a busy band I see it go to 60 dB at
times, that's not a problem if the slider turns RED, back down on the AF.
Then for the output, adjust the PWR slider on WSJT-X about half way
(some say put it to the top, I don't as this gives me a bit of an
adjustment for the ALC later), then adjust the KX3 MIC input to show
approximately 4 bars with the 5th flickering.
This should do it. Again, I use the KXUSB for CAT control which
provides the PTT, and I've never had it fail.

Paul,
Do you have the KX3 set to VOX? If so, it should work.
Have you tried using PTT via CAT in your digital mode application - it
is more reliable than using PTT out of the SignaLink or VOX in the KX3.
Be certain you are driving the audio sufficiently. You must have 4
bars solid on the KX3 ALC meter with the 5th bar flashing. See my
website article at www.w3fpr.com. Scroll the left column to the last
article and click on it to see the document.

I had to send my K3 infor repairs, so I will be using my KX-3 as my
main radio for the next fewweeks. But I haven’t got it working with
Digital modes yet in particular FT-8.
PC is a Win 10 and amusing a Signalink USB. I am able to receive fine
in WSJT-X but not transmit.
Settings in WSJT-X Rig:None PTT-Vox. (Tigertronics suggestionfor
Signalink & WSJT-X)
Audio: Input MicrophoneUSB Audio Codec. Output: Speakers USBCodec
Windows SoundSettings- Both Playback and Recording default set to PC
speakers and mic, notthe audio codec.
Signalink Tx at 2o’clock, Rx at 2 o’clock
Signalink Radio cableto KX3 mic jack
Signalink Audio cableto KX3 phone jack
When WSJT-X goes totransmit, the Signalink Tx light comes on but the
KX3 Tx light does not and Iam getting no power out. I am getting
movement on the Win 10 Playback Vu Meterand sound out of Signalink
monitor jack.
So can someone who isusing KX3 and Signalink give me some hints on
how to get the KX3 to go Tx? I am using Signalink because I do not
want touse the PC sound card for digi modes.
Tnx & 73
