[Elecraft] Poor CW note more testing and a question (rather long-ish...)

[Dick Dievendorff]

External ALC is enabled on the K3 and K3S with a menu entry that defaults to
OFF.  See page 29 of the K3S owner's manual.

"In general, ALC between an amp and a rig is a recipe for clicks and
splatter. Most authorities advise against using it. This is not new -- it's
in the manual for Ten Tec legal limit amps from the late '70s and for every
amp I've owned since."

The OP has a KPA500 and K3S interconnect by an Elecraft AUX cable.  This
means that ALC is connected (Aux cable pin 15) and opens the possibility
that it is not configured correctly.  What I don't know is whether
incorrectly configured ALC could cause the reported problem.  I suspect that
would depend on the time constant(s) of the ALC loop.
