hi all I know suffield police is apco 25 but did they go full time encrypted haven't heard anything in a while on there ch I usually hear white noise on my mobile analog scanner.
I just looked at it in the state base now I know what you mean ,it is mixed mode and one is a Dpl tone and one is a NAC code. That's the first I seen that
155.73000 KCA430 RM 306 DPL Suffield PD Police (Mixed Mode) FMN Law Dispatch
155.73000 KCA430 RM 306 NAC Suffield PD Police (Mixed Mode) P25 Law Dispatch
What scanner do you have? If you have an older BCD996T or that line up, you have to make sure that you have the program setting for audio type to "Digital" and not "Auto". That could be causing some fo your problems. If there is a nearby interference or another entity using the same frequency in analog it could be not switching over to decode the digital if the setting is on "auto".
East Longmeadow was in the clear a few days ago. They normally have very little traffic. I don't monitor Suffield, but EL seems to mostly call in traffic stops, acknowledge a response to a shoplifting call, etc.
