[Elecraft] Line out audio

[Jay Sissom]

This has happened to me also.  Some PC software can't handle multiple sound
cards very well.  When I'm not getting the correct sound from the radio into
the computer, I tap on the laptop a few times.  If I see the extra noise on
the waterfall when I tap, I know it is using the microphone input.
