Bud,
Depending on your soundcard you should be able to turn
off the monitoring so you don't need to change the
Line In level. For example, with the SoundBlaster
Audigy 2ZS, open the Recording Control (input mixer),
click the Advanced button on the Analog Mix input and
select Record without Monitoring. Some Realtek chips
include the inputs on the output (speaker) mixer but
they are generally hidden (select Options | Properties
and show all of the unchecked controls). You can unhide
them and make sure the Line In (it may be shown as a
color) is muted.

Hi Joe,
Thanks for the reply.
I discovered late last night that it was caused by the
soundcard Line-In slider position.
At first I tried muting Line-In. However, I soon discovered
that N1MM would remove the Line-In mute checkbox each time
it played a function key Wave file. The only solution is to
slide the Line-In slider to the bottom (zero) and forget
about the mute checkbox.
Now I need to remember that when going from SSB to RTTY to
raise the Line-In slider position.

If you have a soundcard connected to the K3, it is probable
that Monitor is enabled on soundcard Line In which echoes
the K3 Line Out back to the K3 Line In. If you have monitor
turned on in the K3 it creates a nice echo chamber.

Thanks to both Eric K3NA and Rich VE3KI, I now have Line-In working.
That leads to a new related issue:
When MIC + LIN is turned ON I get feedback from somewhere
when I key
with the foot switch in SSB without saying anything.
If I turn MIC + LIN to OFF the feedback is gone.
I closed N1MM just to be sure it wasn't causing a problem. It
wasn't, the feedback was still there.
Any suggestions?
