There is a backup battery which is float charged from the 13.8V DC power supply. Presently the supply on duty is a homebrew beast of a linear supply (no switchers). I have tried Astron supplies in place of that, no changes noted. There is one public safety repeater, transmit 158.x on a tower 60 feet away. It was not there when my problem started, nor have I ever found their repeater to be in use when my problem is occurring. Actually I'm hard pressed to find that repeater in use, period. Paul
