Let me clarify a point. Use the PWR slider on WSJT-X to adjust the
number of bars on the ALC indication on the radio. Do this in
combination with the {MIC} Line Gain value on the radio. You should
have 4 on solid, 5th flickering. Actual transmit power is controlled by
the PWR value as set on the radio.

Bob,
I have already tried that and several other setting levels. The issue, I
believe, is that the PWR slider on WSJT-X is very sensitive. A very small
movement results in a big swing in actual power.

You might try running the K3S LINE Gain at a lower value, in my case 15 to 20, and running the PWR
slider in WSJT-X a bit higher. This is also affected by the SPEAKER level in the Windows Sound
controller panel. Also under "Enhancements" make sure "Disable All
Enhancement" box is checked.

Ian,
I have the same issue with my K3 and WSJT-X. Great care must be taken when
making the Tx power adjustment, and it is far too easy to significantly change
the ALC level with the slightest movement.

Thanks all for the helpful suggestions - turns out the audio drive levels
are pretty sensitive. The WSJT Power slider on the right is very touchy in
combination with the K3S Mic Gain knob. ALC can disappear in an instance!

Ian,
Are you actually getting RF output? Check with an in-line wattmeter.
WSJT-X is no different than other soundcard data modes.
Do you have the DATA mode input set to LINE IN? If you have a K3S or K3
with the KIO3B *and* are using the internal soundcard, anything plugged into
the LINE IN jack on the K3/K3S will override the audio input from the
internal soundcard.
Do you have the data submode set to DATA A?
The audio drive should be set to produce 4 bars solid on the ALC meter with
the 5th bar flashing - that is the "No ALC" point, the 1st 4 bars are there
to help you adjust the audio drive level. Set the MIC SEL to LINE and set
MIC + LINE to off. Set the soundcard output slider up to at least 3/4 and
then adjust the Line-In (Mic) Gain to obtain the proper deflection on the
ALC meter (you can do that in TX TEST mode without producing RF).
If you have no indication on the ALC meter, that is good reason for no RF
output.
