Just as the name implies, Close Call is just that - close. As N1GAW already stated, either down the street or next door, etc. I used it a lot on the road in my hotel/motels to hear maintenance and security where I was staying. Sometimes I would be pleasantly surprised if and when I caught something unusual, but it was mostly mundane stuff. One night I intercepted repo guys sneaking around my cabin rental searching for a car, they were using FRS blister-pak radios. Very unnerving at first until we figured out who and what they were.
