Yes, improperly or incorrectly using ALC with any amp or any
transceiver, for that matter, can and usually does produce distortion
and splatter. Just look at some of the signals on the bands and
observe the ALC overshoot which exists with many radios. And it is
made worse by the addition of an amplifier in line. It isn't pretty!.
Yet it has little impact on the on frequency signal as heard and thus
the "great signal" complements follow. But look at the other factors
where you will find "NOT so great signal". These points should be
addressed as well.

I have not used ALC with any amplifier since transceivers switched to
transistor finals. From what I have read on this list, using ALC
improperly can cause distortion. Just be very careful with your drive
level. I believe that the KPA500 can handle 100 watts in bypass, 200
watts may be pushing it. The KPA500 is a very nice amp and it is easy
to use with any transceiver.

-------------------------
I have never owned an amp before and recently put together a KPA500. All
seems to be working well, but I have a few questions. I am using with a
IC-7300.
How important is the ALC cable? I notice it is not included in the Basic
Cabling Diagram in the manual but is discussed later in the manual.
If I were accidently to run 100 watts into the KPA500 will the PWRIN HI
Hard Fault/STBY protect itself before any damage is done. Would ALC
protect
me from that?
Is it standard procedure to keep the KPA500 in line when turned off
and not
in use? I see you may run up to 200 through the KPA500 in STBY.
Is there any concerns or settings on radio when running full break in
on CW?
Thanks
