[Elecraft] K3 DVR, Speakers, and feedback

[Oscar Staudt]

I always use a headset with my K3 at home.  I have the Mon level at 1 or 2
so I can hear the DVR output.

As I'm preparing for Field day, I remembered last year we tried to use the
DVR while running external powered speakers on the K3.  Unless the Mon
level was turned down to 0, we would get audio feedback (squeal) when
keying the DVR for a CQ.  Of course, with the Mon level set to 0, then we
can't hear what the DVR is transmitting.  I believe we were using the
standard hand mic when this occurred.

It seems like the mic must have been active when pressing a memory button
for the DVR message to play.  Am I missing something?  Should the mic not
be active when playing a DVR CQ?

thanks,
