[Elecraft] [K3] Re: K3 DVR question

I would also add to consideration that most playbacks are to let the
other end know exactly what they sound like. So adding any equalizing
or processing messes it up.  This would be an issue for me because
hard TX EQ and fair amount of CMP are what transforms my soft voice to
something with over-the-air clarity and punch to it, and I leave it on
all the time.  Turning all that off to effect a retransmit to let
someone hear themself pretty much keeps me from ever using retransmit.

Could it be done in such a way that levels are auto-managed, but TX EQ
and CMP are off for retransmit if it was loaded from the air?
