No guys, I do not have ALC hooked up.
In the manual I believe it says this is not necessary because with the 990
there is no possibility of driving it with more than 130 watts. I am
driving with about 70w to get 1500 out of the amp.
I have some deoxit and will try to clean the contacts and see if that helps.
I can press the mox button on the radio and the amp relays close at
exactly the same instant as the radio goes into tx.
