It has been a few years since I programed my 2096 for the tri county area in Michigan. I'm seeing new control freqs from about 2 years ago and some towers like detroit station gone. 2 Questions what tower site (sites) must I have programed to monitor Detroit city services. I know the reception is alittle shaky. I have re-programed tower sites 202-221. Also has Sterling Hts gone to the MPSCS system?
