Here are some official MPSCS Maps found via google dorking.

I hadn't seen the paging map before. Very interesting! Thanks for posting those.

If Michigan is like Indiana, those maps will be removed from any public access once the state realizes they've filtered out of the need-to-know community. I haven't looked at them yet, because for some reason, when I click on the downloaded file it opens a game app on my phone. 🤷‍♂️ Anyway, like everything else on government websites, if you want it, save it or make a copy, because it could be gone tomorrow.

You are exactly right. These didnt exist on Michigan.gov anymore, but google cached the page. Also, chrome opens PDFs well.

The state of Michigan is completely overhauling the entire site... not just the MPSCS section. Those maps have been available for years publicly on the MPSCS section if the Michigan.gov web site. Once they figure everything out with the links of the new site it will likely come back.

I am trying to figure out the tower site numbers listed in the DB on RR vs. the MPSCS System map.
For example in Antrim County it shows:
Atwood, 042 and on the map it shows 7901 for Atwood I think?
Also, is shows Chestonia, 043 and the map shows 7904.

The 3-digit number is the site ID number that shows up on a user's radio when the user does an RSSI check.
The 4-digit number is associated with the tower.

So a 5-site simulcast cell would have one 3-digit site ID number, but five 4-digit tower numbers, one for each tower in the cell. The system sees that simulcast cell as one site, regardless of how many towers the cell has.
Now you might ask if there is a list somewhere that matches the two numbers. Probably, somewhere. I don't know where. (Other than at the NCC.)

Ok and our Simulcast(Ingham Co) is 27 and it just shows 27 and RSSI with no 0(zero) before the 27 and yes, I was looking for a list that matches the 2 numbers.

The first number of the three (at least this *used* to be the case) is the zone number; So site ID's in the 100's were Zone 1, 300's were Zone 3 (west side from state line to Grand Rapids). The first digit didn't show up on the radio display - I guess you were supposed to know what zone you were in. Most users didn't have a clue, but us geeks had a pretty good idea. 😉
