I'll be glad to make and supply screen shots of my WSJT-X and K3S set-up
if anyone wishes. I find all works correct with the values and
settings I use. I do use DATA A mode thus only one USB cable from the
radio to the computer.

Bret,
I am not certain why that document says to choose the Microphone and
Speaker.
Normal DATA A modes will use LINE IN instead of microphone and LINE
OUT instead of speaker.
In other words, you may be overdriving the input to the soundcard
which will give you a 'funny' waterfall display as well as being
varied by the AF Gain control. The LINE IN gain on the K3/K3S is
controlled by the LINE IN menu setting, and once set will remain
fixed. You can also use the computer soundcard slider to adjust the
volume.
Similarly, the microphone level when microphone is selected for the
K3/K3S input may prove to be difficult to adjust for the required 4
bars on the ALC meter with the 5th bar flashing. It should be better
to use the LINE IN setting. The MIC GAIN is used to control the LINE
IN level when LINE IN is selected.
Remember with Elecraft gear to set the audio as described - 4 bars on
the ALC meter with the 5th bar flashing is the NO ALC point for the
K3/K3S/KX3/KX2. Do not attempt to control the power with the audio
level, set the audio as indicated and control the power with the POWER
knob. Yes, Elecraft controls power differently than other amateur
transceivers.

On my K3S/100 using WSJT-X set up as per http://tiny.cc/K3S-WSJT-X with
v1.80rc1 on FT8 I adjust my RF knob to a 30dB noise level. I often
see ~10dB
difference between even/odd 15sec cycles with no visible difference in
background noise on the waterfall. That is, at 28-32dB on even I
might see
~40db on odd. Is this just faint signals on one 15sec cycle not
apparent on
the waterfall on the other 15sec cycle? But if I hunt around for open
waterfall areas I seem to always see that ~10dB difference. Hmmm...
