The first thing to check is that you are actually feeding audio into the
K3 MIC socket.
Assuming that's OK, you also need to make sure whatever tone the WSJT
software is generating is *below* the cut-off frequency of the K3's
baseband audio filter.
I've found on my KX2 that under certain settings, it's possible for WSJT
to generate tones that are above this cut-off frequency (about 3KHz from
memory), the symptoms are exactly as you describe (rig goes into
transmit, but no R.F. transmitted).

Hello to the group.
I am receiving no problem at all. I am however having difficulty in getting
WSJT-X to transmit. I am using a K3s.
I have the K3s set up for Data A (USB) mode operation and have the MAIN:MIC Sel
set to LINE IN.
On the WSJT software Settings under the <Radio> tab I have selected the K3
under Rig, set the serial port that I normally use for CAT control (COM 5 in my
case), I have set PTT method to CAT, the set Mode to None, and set Split
Operation to None. Not quite sure how to change the Transmit Audio source
setting as it is greyed out. It is presently set for Front / Mic.
If I hit the TUNE button on the WSJT software my transceiver goes into transmit
mode but there is no output at all.
Any help/guidance would be greatly appreciate. Thank you in advance.
