Looking at your file, and also the page for your
county in the database, I see several things.
It appears that you imported the Ann Arbor/Washtenaw County
trunked system, but not the statewide
MPSCS TRS. Reading comments on the database page, as well as in the Ann Arbor system, it appears that, as far as public safety is concerned (law enforcement, fire, EMS, etc), the Ann Arbor system is basically being used as a backup for MPSCS. If you look at your original file, and more specifically at he Ann Arbor/Washtenaw trunked system, you'll see several groups that are empty, no talkgroups at all. Look at the first two for Ypsilanti Township. Nothing in there. If you look at the
system in the database, you'll see that all the talkgroups listed for that city are tagged as "Depreciated", no longer in use. You have others the same way, plus some, like Washtenaw County Fire Operations, are listed (in their description) as "fallback". That indicates that these might still be used if there was a failure that made MPSCS unavailable. I suspect that the same may apply to some of the conventional frequencies as well
What I've done, in the attached file, is that I imported your county's talkgroups from MPSCS. I did a blanket import, to get everyhing. I'm sure that there will be stuff, like Public Works (roads, for instance) that are not of interest to you. You can lock out whatever you don't want, or delete it from the file before you load to your scanner. Try the attached file and see if you notice a difference. The attached file is zipped. Unzip it with whatever program you used on the file you originally attached. No need to change the file extension; just unzip it.
I did not make any changes to the Ann Arbor trunked system, nor to your conventional files. I have no way of knowing which are correct and which are no longer used. I've never been to your area, and, of course, am far out of range. If you need help with the conventional frequencies, you might ask that your thread be moved to the Michigan Forum. To do that, do
not create a new thread. Instead, click on the Report in the lower left corner of one of your posts, and request that a moderator move your thread to the state forum. Someone in the area would be more likely to see it there.
