We tried all of those suggestions. He turns a few things down, for a while, then when one or two people (with worse hearing or equipment than he) complains, he just turns it back up again, figuring since nobody complained any more, he must have turned it down too far.
The main repeater is a brand new (well, now 1 year old) Kenwood that's feeding a 200w amp. If he had left it as it came from the factory and not tweaked and twiddled every setting, we wouldn't be having this discussion since there wouldn't be any over-deviation, just excessive limiting going on, but at least it would be filtered and would peacefully coexist with its neighbors 25 kHz away. I'm lucky; my repeater is only a mile or two away but it's 50 kHz away and with the same in/out relationship, so I don't have any problems. The problem with showing up, equipment in hand, ready and willing to help, is that when I did that one time long ago, I became his resident fix-it man, and he called me for everything, and it became too much of a bother because he just wouldn't leave well-enough alone. Even after adjusting everything to spec, he still tweaked things himself. So no one volunteers like that any more. They get sucked in and then there's no way out.
