Steve, thanks much for the the good info that you have just given to me. In
the past I have always used the radio drive power but I have wondered about
the ALC and how to adjust it. I have an old Alpha 78 that I run in the no
tune position so all I have to do is make sure my standing wave is OK and
set my radio drive power. I usually run barefooted anymore but sometimes I
use the amplifier. Seventythree,
