I still think it may be something in the vicinity of the antenna. What kind of building is the antenna mounted on/above?
You've stated that the repeater is in a metal pole building that's 100ft. away from the antenna. It's been mentioned before in this thread, but that could be a noise nightmare. You'll need to get your antenna much farther away or higher to get away from that noise if that's it. If you have a small beam that you can hand-hold, that might be interesting to point around and see of there's changes in desense. Laryn K8TVZ
