Hi Don -

I'm going from the soundcard (it's USB) out to the K3 line-in. And last time I used 
it it worked fine, PSK doesn't xmit either.

No interface, just the soundcard.

I can't get any alc reading, the rig doesn't go into xmit. By "audio drive" I take it 
you mean then "Mic" knob. My line-in level is 23. I get an alc reading in SSB, but 
not data. If I plug fones into the sound card, it is making the tones.

I don't see a Line-in menu setting. There is a MIC SEL that's set to Line-In.

73, Mike NF4L
