Spot on, Jim! I have NEVER used ALC with any PA. BTW, most ACOM amps for instance do not have an ALC output - they must know why! Misuse of ALC is the cause of many bad (not to say horrible) signals we hear on the bands... It's so easy to reduce input power... And my K3/KPA500 combo does it automatically.
