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

[Gary Smith]

Perhaps the point of my original post has 
been missed.

The only way I could get RF out of the K3s 
was to assign the K3s codec as my default 
in the sound settings. If I did not do 
this in the windows sound control panel, 
the K3s would go into transmit mode with 
WSJT-x but zero output.

Doing this allowed computer sounds to be 
transmitted with WSJT-X, maybe with AFSK.

Yes, in the WSJT-X software I always had 
the K3s codec checked.

Until I made this change in the windows 
app volume and device properties page 2 
days ago, that was the only way I could 
transmit with WSJT-X.

I cannot be the only person with this 
issue. 

This is not a trivial issue, we all want 
our signals to be clean and for months I 
had no idea I was occasionally  
transmitting garbage with my K3s. I'm sure 
others here are doing the same.
