I have 2 banks with conventional systems and 2 banks with trunked systems. I scan all at the same time using my quick keys. I have priority channels set in all 4 banks. Why is it when I isolate the 2 conventional banks and only listen to the trunked systems it says "Priority Scan No Channel"? Even if I have priority channels set in those banks? I have priority channels set and I have priority mode on but, it still kicks it off.
