Where do you have your soundcard level set? Set it at the 75% point or 
a bit higher. 

One "eccentricity" of the KX3 is that *if* the audio input is too high 
the KX3 will protect the audio input by shutting it down. Start with the 
MIC GAIN at a low level and bring it up slowly until you find the point 
where you have 4 bars solid on the ALC meter. If the mic gain setting 
is at a rediculously low level, you can add some attenuation in the 
audio cable - 100k in series and 10k across the line at the K3 end will 
give you about a 10x reduction in input to the KX3. 

Instead of using USB mode, use DATA A - it is almost the same thing, but 
compression is automatically turned off and the equalization is 
automatically set to flat. That leaves your SSB settings intact when 
you go back to voice.

For WSJT-X make sure you turn on VOX (hold DLY button) also go into Menu and turn off mic button up and down function and mic bias. 

For HRD, use the K3 radio. It works for me.

I get this message whenever I have another program using the 
USB<-->Serial port to the KX3. It is most often my logging 
program. I just quit the logging program, click "Retry" in 
WSJT-X and everything is OK.
