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

Sat Jan 19 22:23:15 EST 2019

This type of discussion makes me wonder if folks are feeding audio 
direct from the computer to the Line IN on the rear or to the MIC 
input.  If they are using an external soundcard, i.e. Signalink or such, 
then I can understand Windows sounds being heard.  Not good.

If they are using the USB mode {and not a DATA mode, with the Menu item 
MIC + LINE set to ON, thus anything picked up by the mike is also 
transmitted along with WSJT-X data.

It would do well to carefully listen to your MON with headphones to see 
what exactly is being transmitted.    Correctly configured, only the 
WSJT-X data is transmitted......and as it should be.
