I have a 1980 Regency Touch ACT-K100 scanner that my dad used to use when he lived in PA.He has since passed and now I have it. I want to sell it but I want to be sure it works first. I don't know anything about police scanners and it's only an interest when I hear a siren driving by. It has an antennae and the red lights come on -- it appears to be scanning. Everything seems to work but I don't pick up anything. I move the squelch and volume back and forth and still nothing. I've manually entered local frequencies that I found on this site and still don't pick up anything. Can someone offer any useful advice as to what the problem might be. I'd really appreciate it.
