The Medcomm channels are actually licensed to TCEMCA, and I suspect until such a time that the hospitals only have one radio to use, they'll stay non-edacs UHF.
The EDACS rigs can easily be programmed for the existing medcomm channels, and hospitals arent fond of adding more radios to the mess.
Ingham is the only county of the 3 tri-county agencies using EDACS. The hospitals didnt convert to 800 when Clinton Co did.
