Ok guys I think I resolved the squeeling problem. I Got to the site
this morning while guys were using the rptr and the problem was
existing. When tuning the PA awhile back I noticed if you went to far
one way it would oscillate (feedback, whatever) or go spurrious. Where
I thought was the prop

Ed covered it... it's the type of combiner it is. :-)
145.145, 145.385, 146.67, and 146.94 were the original frequencies in use.

Paul,
No, hybrid ring is totally different. The cavity / isolator example I
referenced is similar to a normal duplexer with th
