I see from your club website that you are running braid/foil coax and RG-213 as jumpers to the duplexer. You might want to consider a change to heliax for the antenna run and superflex heliax to the cans.
That said, you may still have other issues at play. But it's always best to clean house first.

Good morning on this soggy, Friday Morning. We've been experiencing a recurring problem every once and a while. It's not our repeater, but its driving me nuts trying to figure it out. It sounds like badly tuned can's, somehow feeding the output back into the input.
