i am still a little confused on how priority scanning works on the BCD996XT. I have 2 separate trunked systems and a conventional Vhf system that I scan regularly. I have a channel on the conventional system set as priority but the scanner never jumps to this channel. Putting the scanner in priority mode chops the radio traffic up every 2 seconds and putting it in priority plus mode only scans the priority channel. How is this feature supposed to work?
