I have a G4 Unication scanner and live in Michigan. I have (not encrypted) one FD and one PD talk group each from a couple neighboring towns and a few other towns all in the same county. However, I am only able to hear a handful of the talk groups I have on this channel bank. They are all on the MPSCS system too. There does not seem to be any rhyme or reason to why some are working and others aren't. For example, I can get one town's FD/PD that are a few towns away but cannot get one that is right next to our border. I can another one that is several miles away but not another one a similar mileage away. I think it has to do with the RFSS/Site. Can anyone make sense of this?
