(LAPEER COUNTY) -- After several years of work, Lapeer County Central Dispatch switched from an analog radio system to a digital radio system on December 18. The amount of radio towers used was doubled from three to six. Sites are located in Almont, Metamora, Imlay City, Lapeer, Burnside Township and Deerfield Township. The state's Deerfield site was also absorbed into the county's simulcast as part of the project. The analog system had ten frequencies and two of them were dedicated for data usage while the remaining eight were left for voice channels in the trunking system. The new digital system now has fourteen frequencies allotted for voice. Data is no longer used since changing to a cellular configuration earlier in the year for police in-car computers. Lapeer County users are among the first in the state to be ready and capable of utilizing 700MHz frequencies should they become available in the area.
