A friend has an invisible fence for her dog. The wire was apparently severed by someone turning over soil in a rather large area adjacent to her property. She claims to have used a portable radio to find the break in this system before, but she can't remember whether she was using the AM or the FM band. In any event, this time she has tried a different radio (the other one is broken) with no success. My question is: Can one use a radio to find a break like this? And if so, how is it done? If not, is there an inexpensive device that could be used to do it? (She doesn't want to spring for a metal detector.) I really don't need more info, but would like to know a little more about how invisible fences work. I would assume the wire simply acts like a transmitting antenna. Your help is, as always, much appreciated. Thank you. Frank
