I have a couple DMR radios. One is a UHF HT and the other is a dual band 20 W mobile.
As Tate said, there is one DMR repeater in Natrona County, operated by the Wyoming DMR project. As far as I know, that project provides two talk groups and is not connected to any of the larger DMR networks. One talk group is a local group, repeating only to users connected to the same repeater. The other talk group is statewide. I used the statewide talk group for an exercise in March to talk to LCEMA to coordinate Winlink traffic. All code plug information is on the Facebook group under files.
It's been a while, but I believe CPS was the software for my mobile radio. I found it to be pretty clunky. I ended up using

I have some time next Saturday if you want to do a weekend workshop.
