An update that is from some compiled information I have been able to find. The Towers are all constructed and wired up except the Central Fire Tower. Radio Training was starting and the 800 Pagers have been programmed and will be rolled out soon. Looks like they are still doing some radio testing every Thursday with yesterday having some tests from different road locations in Muskegon and Ottawa Counties. I have also found the following talkgroups with the audio of "test" for each:
23199, 23326, 23306, 23305, 23301, 23294, 23293, 23292
I was in the area this past week and had a "search" run for the frequencies listed above in the FCC licenses, without connecting to any tower.
