Hi all newbie here just had a question about the squelch settings on my scanner (pro 97) I was curious to know if anyone else on any other model of scanner has to have there squelch more than 3/4 the way open .... I read my users manuel and it says turn the squelch setting clockwise and stop just after you hear the hissing noise stop. When I do this and scan my bank or banks it stops on almost every channel with no broadcasting, I double and tripled checked that I had the right frequencies for the agencies and that wasnt the problem.If I turn the squelch open almost 90 percent it will scan normally. Ive had the scanner now for about a month and it just recently started doing this. Is this what you consider like a sensitive scanner, should I excahnge it, any help would be apreciated thank you.
