I lost all reception on my 996XT all of a sudden. I manually go to the channels I see "searching for control channel" appear briefly and then it races through the programed systems. I was scanning analog trunked systems and one P25 system. I don't have close call activated or priority on. It's not my antenna because my GRE 800 works fine on it. I did a reset and loaded my systems back in from a previous upload. What am I missing?
