Sometime yesterday my Pro 97 stopped being able to trunk track and I was having trouble with some conventional frequencies. I was charging my scanner most of yesterday when I had a chance. I was using the standard duckie. I kept trying to adjust it to detect control channel noise on nearby systems but that reception was spotty. I never had this trouble before really. I got a new antenna today and I'm still getting the same troubles. I live in the Philadelphia, PA area. This is occuring on all trunked system types. In fact, I can't even pick up any kind of signal on the Sunshine Philadelphia VHF system with either antenna. Any idea what is happenning here?
