I bought a Pro-97. I know nothing about scanners. I figured it would require some frequency programing to be useful, but I also thought I would be able to hear something before I got around to programing. I should at least hear noise, shouldn't I? When I turn it on, there is no sound. With the volume at max there is a very faint hiss. Squelch has no effect at all. When scanning pre programed frequencies it never stops. When using Signal Stalker II, it never isolates a signal, but it occasionally slows down for a fine scan of a frequency range. When scanning the weather band, it never stops. It seems obvious this thing is broken, but since I am so ignorant, I just thought I would ask if there was something I was missing.
