The 146.67 repeater is still down due to it possibly bleeding over into the Groton Fire Alarm Dispatch channel. The problem appears to be that the entenna is co loacted on the same tower as the 151.925 antenna. They also use the same PL of 156.7 on there channel and it appears that when our repeater is being used the signal bleeds over into there reciever. We are actively working with them to correct the problem. This may require us to change our PL to reduce the possibilty of opening their receiver. We also have acquired a Isoloator to put inline with the antenna to hopefully reduce the chance of interefering.
The cause of the interference on the 146.97 repeater appears to be coming from the 5GHz flat panel antenna co-located at the site about two feet away from our repeater antenna. I have posted pictures in the photo album of the antennas. We are working with the contractor to find a resolution to the problem. I think the only solution is better sepearation. The problem drastically reduces the reciever sensitivity for weak signals. Hopefully we can solve this soon.
