WSJT-X works very well with K3 and KX3 set for Digital A. As others have 
noted, we need to set the bandwidth per mode. I don't know how to 
interpret the image you posted -- there's too little time on the 
waterfall, and no amplitude display.

This almost looks like the sort of problem that could be from a miswired 
cable, or from not having equipment bonded together properly. You should 
be using the Line Input of the K3. When the Line Input is selected, the 
Mic Gain knob acts as Line Input Gain.

See http://k9yc.com/GroundingAndAudio.pdf for detailed advice on 
Grounding, Bonding and Audio Interfacing.
