[Elecraft] K3S No TX Audio via USB

[Don Wilhelm]

John,

Have you looked a Windows Mixer to see what the output level of the USB 
Codec in the K3 might be set at?

Set it to about 75% of full volume.

I don't know what is different about WJST than other data modes, I just 
know that there have been many more posts on the reflector about it.  It 
should be "just another data mode", but many users seem to have similar 
problems.

Have you tried it in DATA A mode rather than USB?  DATA A normal 
sideband is the same as USB but with compression automatically set to 
zero and TX EQ set to flat.  You will have to widen the default 
bandwidth for DATA A, but that is a simple matter of moving the WIDTH 
knob (or HiCut/LoCut).
Much of the internet advice does not consider that the K3 (K2, KX3, KX2) 
are different in the way power is controlled than other transceivers. 
With Elecraft transceivers, set the audio drive correctly and control 
the power with the power knob.

Set the audio to produce 4 bars solid on the ALC meter with the 5th bar 
flashing for the K3, K3S, KX3 and KX2.  For the K2, increase the audio 
until you see an ALC bar and then back off the gain until it disappears.

73,
