As most of you know we have had some issues with noise on the repeater’s input. We have isolated the issue to something on the tower. Over the weekend Corey, KD9HCW, and Bob, KC9IQR spent several hours at the site hunting noise and testing our equipment. No attempts to filter or block the noise have been successful. We are making plans to do some housekeeping on the tower in the spring in hopes we can solve this issue once and for all.
Here is an article from Repeater Builder that explains the issues in greater detail.
