MSWIN also was designed for mobile coverage, as are pretty much all Statewide systems. But knowing this, MEMA, MDOT, and MHP did indeed add vehicular repeaters to the mix, just like they had when they were on VHF. I would assume at least THP would have done the same if they were wise. As for local users adding them.... That you have to talk to the Communications Directors (Radio Guy) for each agency as its not standard issue. Its looking like they will need to add at least an mini site to fill in if not a full on site.
