Nothing has changed, and when it does, there is a pretty good community of us that quickly get the database updated. he issue seams to be with your scanner. Are you scanning only the county P25 system with site lock on or are you also scanning other systems/freq. If you are scanning other things, you will miss transmissions.New to the game and just picked up a BCD436HP and looking to listen into police chatter in Chester County. I updated firmware and downloaded the latest database, but I still don't hear much/anything, even when holding just on System: Chester County Emergency Services and Dept:Law Enforcement. It never seems to pick up any traffic. Has anything changed or can I just not pick up PD traffic on the BCD436HP?
