[Elecraft] FT8 using internal USB sound on the K3S

Nope, it's in DATA A.  WSJT-X's CAT control works fine with the K3S, 
setting frequency and DATA mode to DATA A (I forgot to mention that, 
sorry).  The problem has NO relation to the filter controls or any of 
the other stuff.

Thanks Rich, but I already have WSJT-X set up the way you suggest except 
I never touch the equalizations.  I've found in the past that it only 
distorts the signal.

The problem as I have stated twice now is WSJT-X can't open the audio 
device.  Windows 10's device manager reports it is working properly.  
CAT via the same USB connection works properly, reads the K3S frequency, 
sets the mode to DATA A as it should, test CAT and test PTT work as they 
should.  Just no audio input from the K3S.  I have NOT tried TX audio to 
the K3S and won't until I get the audio input working in receive first.

Thanks,

Jim - W0EB
