I just got a used radio shack pro97 scanner and everytime someone stops talking on a frequncey it will beep 5 times.Very annoying! Do all trunking scanners do that? I have the conventional scanner that does not do that. I only have a few programs in it. If I had alot of them it would drive me nuts and I have been listening to scanners for over 30 years. I am new to the trunking type maybe it is normal or maybe its a cheap model !
