Thanks for the replies, guys. I understand a bit more about ALC
protection today than I did yesterday. Still not sure I want to do
without it, though.

Jerry,
The ALC on an amplifier is a feedback path from the amp to the exciter
that holds the amp output to a certain level by reducing the exciter
output and thus the drive to the amp. ALC will not protect the amp
from a high SWR condition. Most amps these days have over drive
protection an

I agree, and for what it's worth, I seldom talk to anyone these days
that do run an ALC line to their amp. My Henry will shut down if I
ever overdrive it, and I don't think the SDR can even do that except
one time when I ran a sine wave on AM with asymmetrical modulation to
the dummy load. I stil

I am considering using an SDR1000 as driver for my Quadra amp.
In looking over the SDR1000 docs, I can't find a way to hook up my
Quadra's ALC control line to the SDR1000.
My present setup uses a 756PRO, which provides an ALC input jack so
that an external amp can make the 756PRO cut the drive
