[Elecraft] K3s can only transmit wsjt if the K3s codec is windows default.

[Gary Smith]

Peter,

Absolutely brilliant! I never have seen 
this windows page or read about it, but it 
absolutely did the trick. I now have an 
alternate soundcard selected in windows 
sound control panel and have WSJT-X 
configured in App volume and device 
preferences.

I have to experiment to be sure nothing 
gets out sound-wise from the computer but 
at first exposure, this looks to be dead 
on.

How many others have not yet discovered 
this!

73!
