I have a BC125AT and listen to police and fire in Rio Rancho. Lately, some of the channels I have programmed, that worked previously, are now making only clicks and static. The signal strength indicator remains strong on all the channels. I do receive the dispatch channels just fine, but the secondary channels are the ones that click and make static. Can anyone tell me if they've changed their equipment and if I need a better scanner? Or if those channels no longer available?
