Iain, I think you win the prize because that would explain everything I'm seeing. When I run out to the station this weekend, I'll give it a try. I appreciate you setting off my Ah-ha alarm and clearing my fog. ;-)

Control Panel -> Sounds and Audio Devices -> Audio Under "Sound playback", click on "Volume..." Options -> Properties Check that the appropriate "Mixer device" is selected, and that the "Line In" or "Line Volume" control is enabled. Click "OK". Find the "Line In" or "Line Volume" control and check the "Mute" box below it. That should prevent the monitor audio from looping back out to the rig. ~Iain / N6ML On Mon, Oct 18, 2010 at 4:20 PM, K5WA <k...@comcast.net> wrote: > I thought I knew my K3s pretty well but I've got a simple issue that I can't > seem to figure out so I thought I would toss it out to the crowd to see if > you can clear my fog.
