[Elecraft] K3 Monitor feedback

[Ken K3IU]

Thanks... I apparently did have a sneak path. I opened the Playback 
Control on the sound card (SB Live! 24 bit) and muted the Mic and Line 
In (to the sound card) and that fixed the problem with the MIC+LIN set ON.

Thanks, Mark, for the hint. I really wasn't that concerned 'cuz I rarely 
use phone, but glad I fixed it anyway  ;-) .

73, Ken K3IU
