The ham radio folk, of which I am one, are probably down there with scanners now and could tell you the problem ;-) Before I was a licensed ham I put together a little AM transmitter with a 9v battery connected to a portable cd player. I was shocked that I could pick up the signal several miles away (and yes I know hams, very bad behaviour, I was ignorant). I'll put my money on a new antenna having gone up nearby.
