Mike,

Where is the "PWR" slider set in WSJT-X?  The PWR slider is really the
audio output level and should be set to 100% *and left there* with the
K3/K3S.  The audio input should be adjusted with the Line IN control
(Mic Gain encoder) for four to five bars of ALC and the power output
adjusted with the PWR encoder.

In general. my K3 is set to Line 20, the Windows Sound Mixer for
"Headset Earphone (microHAM CODEC)" is set to 70% and the TX pot
on MK II or DK II are set between 12:00 and 3:00 as needed to get
four bars of ALC on the K3/K3S with the fifth bar just flickering.

Your Default Device (and Default Communications Device) in the Windows
Sound Control Panel -> Recording tab should be an input of the sound
card in your computer.  "microHAM CODEC" should *NEVER* be used as a
default device for either Playback (transmit) or Recording (receive).

Please refer to the "Configuring microHAM CODEC" and "Setting Audio
Levels" section of the DK II Users Manual.  Follow the "Setting Audio
Levels" procedure *exactly*.  Do not proceed from one step to the next
until you obtain the results called for in the procedure.

Note: the K3/K3S overloads the mic gain control (uses it for both
mic and line levels).  Line In can only be set when DATA_A or AFSK_A
is selected and MENU:MIC SEL=Line IN.


73,
