[Elecraft] K3 - Can't seem to make LINE-OUT work properly

[Dan]

Joe, 
Thank you for your insight. Audio coupling to the microphone was INDEED the
culprit. Turns out the input line on the notebook was bad and needed
repairs. I also needed to turn off the microphone to make sure it does not
interfere. Actually was the Laptop's own mic picking it up, not something
plugged into it.

I recorded the LINE-OUT from the K3 and it is working as spec'd. No issue
with the K3 at all, just operator error!  Thanks again Joe!  Issue resolved.

Check your soundcard.  This report pops up occasionally and the
user has a microphone/VoIP headset plugged into the mic input of
the soundcard.  Windows will automatically select the mic input
of a soundcard if it detects a mic connected (or the built-in mic
in many laptops).

When this happens, one is getting "acoustic coupling" between the
transceiver speaker and the microphone input of the soundcard.
