I have this channel (477.0625 PL 179.9 repeater) programmed in my scanners and a number of times throughout the course of a day I get heavy static on it. It usually lasts for 30 seconds to a minute. I've never actually heard anything on it except for the static. Does anyone else monitor this channel and if so have you experienced this? I would imagine there's no explanation for this except for the possibility of interference from another outside agency. However, I was thinking Kevin Obrien may be able to shed some light on this.
