I frequently listen to the Burlington County Fire and EMS feed that has all the response zones and county dispatch. I notice something very strange though with the feed. When I have headphones on and there is nothing coming over the radio I swear I can hear very faint talking in the background, and I'm not sure yet, but it really doesn't sound like another radio. Is it maybe crosstalk from another feed? What the heck is it? I'm positive its not anybody in the room I am in or an adjacent room.
