[Elecraft] K3 Echo in TX Audio

[iain macdonnell - N6ML]

Do you have the line out of the K3 connected to the line in of the
sound card? If so, disconnect it, and see of the echo goes away. The
sound card may be passing the line in out through to line out, which
you're feeding the K3's line in - that would capture the monitor audio
and feed it back to the K3. You may need to mute line in in the
playback mixer (in Windows).
