Grayling EDACS is still on the air, but roscommon is not. St. Helen MPSCS is now using 859.8125 which was on the EDACS West Branch site. On MPSCS Grayling, a few new channels matching the consumers license were commissioned in June, and are now active.
On Grayling EDACS, i see no traffic, except denials for one user that was always just a data burst of some sort.
On their EDACS system, they seemed to have the ability to request to talk. Fromthe discussion I heard, It sounds like they have a button on their new radios to do the same thing. For example, there is no traffic, and all of the sudden dispatch says "go ahead xyz unit"
