I have Philly Mot 800/900 and Bucks County Mot 800/900 programmed in my scanner and some conventional frequencies like PA Turnpike Dist 4 and Philly Airport and NE Airport. All downloaded and programmed from RR via the Radio Shack software with the cable hooked up from computer to scanner. Up until about a week ago the scanner worked just fine. Now there is no audio from the 2 trunked systems, Philly MOT 800/900 and Bucks County MOT 800/900. However there is audio from the conventional frequencies like PA Turnpike. The scanner will stop on the Philly and Bucks channels but no audio. When it stops on PA Turnpike and Airport channels I hear the audio. So my question is has anyone had this problem with the Pro-106? If so could someone please post a solution to this problem. Thank You, Bob
