David, the "Fix" for a Maggiore
repeater working in to a duplexer becoming a "comb generator"
is to put a small antenna tuner between the TX and
the duplexer.
We fixed a problem here by doing that.
The "Z" matcher that was discussed on here while
back would work as well.

Someone in our area has three Z Matchers for sale
but the price is a bit high.
Does anyone out there have a suggestion as to a
fair price for these units ?
As I recall they were in the area of 80 - 90
dollars several years ago.
