Hi Bob, I do not use ALC with my ALS600 and my K3. Works great without it. Usually use about 45 Watts in and get about 450 Watts out for MARS on 2.2 to 4.1 MHz. Just connect "key out" on back of K3 to "relay" on back of ALS600. There is also a recommendation that is worth reading in the K3 manual to not use ALC for certain purposes.
I am real careful tuning for low swr at 5 watts in first.
