I tried listening to Cecil County, MD on a recent trip to Delaware on my 436HP. I didnt hear anything. I had all the frequencies programmed in LCN order, the system set to Narrow EDACS. I have the latest firmware on the scanner so it can hear ProVoice. I was receiving the control channel well. The only thing I didnt do was program any talkgroups in but I did have the system set to ID SEARCH. Is that the issue? Or is there something else I have to do?
