I'm almost certain that's the reason.
Look for Athens County EMS and fire departments to do the same thing soon. We were notified that Athens County Emergency Communications (9-1-1) will no longer support any of its analog radio systems, and that - if you want to be dispatched by them - you'll move everything to MARCS. All voice traffic is already there except for some of the volunteer fire departments. The paging operations for EMS and fire are the holdouts for now, but B&C is pushing hard ($$$) for the transition to occur.
Hopefully they’ve paid attention to the NFPA, which recommends an alerting system separate from the voice system. That way if one craps out, the other is probably still there.
One of my issues with MARCS in the past is that they suggest that their new customers can dump all their old radio systems, MARCS of course being the be-all, end-all (the customers fall for it in the name of ”savings,“ even though the cost of maintaining an analog repeater is very low). There’s no support given for backup system planning, and when MARCS takes a dump (as it has occasionally done), the customers are left with a disconnected bunch of towers. Pickaway County got around this by programming a zone in the radios where the talkgroups are locked to the Pickaway County tower, so in the event of a system crash, they can at least talk to each other.
