BCD996T Control channel problem

[Gregg251]

All of a sudden I stopped hearing communications on my BCD996T on the local (Guilford County, NC) trunked system. I made no changes to the scanner. Also, my Radio Shack Pro-96 and 2096 receive as well as always. When I lock the 996T on a talk group (e.g. County Fire), I get a message that says "Finding Control Channel". When I listen to the frequencies manually, I can hear the control channels. Could I have inadvertantly locked something out or made some type of change to the set-up?
Any help is appreciated.

Thanks, Gregg, N2UUP
