A few years ago I lived in the Poconos and, in the winter, did snow-making at night (for the fun of it actually). One of the employees (the lead snow-maker) was a police officer and he had some radio that picked up calls from Philly. I'm not sure if it was one of these or what. He had one that picked up calls from NYC but it wasn't hand-held like the other one was. Sometimes he would play it over the loudspeakers as we were on the mountain.
