>I need to set the K3 LINE OUT level well above 50 before I can see a trace on MixW's waterfall, even with the soundcard's line in level set to maximum.
Bob, some of us have measured distortion on the line out connection on our K3s and find that it is significant on high line-out drive levels. I think the manual suggests nothing higher than 10. Mine has noticeable artifacts on a waterfall with a single tone RF input from an XG2 signal generator with any line-out gain setting above 3. Luckily that is just enough to drive my internal soundcard, YMMV.
