The DMR system is still operational but Jackson County is rapidly moving toward MARCS. The holdout, as you might imagine, is the underfunded volunteer fire departments that have struggled to buy trunked P25 radios, replace pagers, and find the money in very tight budgets for user fees. But it's happening.
Law enforcement, with the exception of Wellston PD, is fully operational on MARCS. Wellston is waiting on additional MARCS radios and mobile repeaters before making the switch. For now, find them on 453.675 MHz with MotoTrbo emissions.
EMS is 100% on MARCS including paging.
The county engineer is moving to MARCS. No timeline that I know about but they were very active on their talkgroup last week during flash flooding with lots of closed roads and debris that needed cleared.
Fire still dispatches on 453.625 MHz analog countywide with the exception of Madison-Jefferson FD in Oak Hill which uses 453.125 MHz. All fire departments hope to be on MARCS by September 1st but the 453.625 simulcast of alerts is expected to continue indefinitely. This is to allow the departments to transition to 700/800 paging after the UHF radios are replaced.
Jackson city public works is still using 154.115 MHz. I have no idea if they'll eventually join MARCS.
The DMR system will probably bite the dust within a year or so. Jackson County isn't paying to maintain it so when something breaks, it stays broken. The sheriff (who oversees the county 911 Center) has been telling everyone that the UHF radios will be pulled from the dispatch consoles soon and everything will be on MARCS.
Personal opinion: MARCS works reasonably well in Jackson County. There are a few dead spots that, if addressed, would make MARCS a great system for public safety.
