Etienne,
A frequent problem is that the Bias is not turned on when using the MH2
microphone. It is an electret microphone and needs bias to produce audio.
As for your DATA mode operation, are you using DATA A mode? You should be.
Do you have the mic select set to Line IN? If not, that can be the
problem. Do you have anything plugged into the K3S Line IN jack? That
overrides the Line IN for the internal soundcard.
Do you get any indication on the ALC meter - you should set the audio so
you have 4 bars solid with the 5th bar flickering. You may need to
adjust both the computer soundcard speaker or line Out sliders and the
K3S mic gain (actually Line IN).
73,

Good day,
I am adressing this issue to this forum as I am puzzled and don't know what
to do.
Basically, I assembled my K3S kit about a month ago, no issues with the
build and initial testing. I have done all of the required calibration and
even the RF Gain calibration using the XG3 signal generator.
Everything worked out fine, I was able to receive signals and hooking up my
paddle I was able to transmit in CW. Since I have the TX Monitor option, I
was able to see the signal and power output on the P3 display. I did put
back the radio in his box and put it aside for about a month as I was busy
with other family issues (i.e. a new baby).
I pulled back the radio last week as I wanted to play with the digital
modes, after fiddling with the settings I was able to hook up the computer
and the radio using the USB cable to use the internal sound card and
control. I am able to receive signals on my computer, I can see the received
signal on the computer display so I have no doubt that the sound card
drivers are working. I configured the software to control the radio and when
I start to transmit using the software, the radio turn into transmit mode
and the TX red LED lights up.
