What you specifically want to receive is talkgroup 22245 (and possibly the other talkgroups I've highlighted in the attachment). How well you receive them depends on your location and scanners sensivity to the simulcast distortion in your area. I personally cannot receive anything reliably (or at all) on the Detroit simulcast site for MPSCS Wayne County (82) on my BCD536HP, so I don't scan that site, I live North-West of Dearborn. I do, however, get MPSCCS Wayne County (82), and thus talkgroup 22245, very reliably on both the Northville and Waye County simulcast towers. I suspect that you might want to try the Wayne County simullcast site for the strongest signal in Dearborn. Good Luck!
