Default Can't figure out what system this is running

So while scanning around, ended up finding 4 DMR sounding frequencies. All of them seems to be being used by the same operators. Dont get much voice seems like mostly data. Also seems to be idling mostly. Any help trying to figure this system out would be appreciated

https://hastebin.com/nimoweroqo.cs this is the radio list
https://hastebin.com/laguwidoxe.sql And this is the log file.

Dont have any raw recordings

You are not helping us alot
RAW audio is the best way to start. Frequencies might also help someone to identify the network.

The frequencies start from 427.125 to 427.250. I'll post raw audio as soon as I can. Seem to have broken the antenna connector on the SDR.

Looks a lot like a single channel conventional DMR repeater.

This seems to be running 3 frequencies. Same RIDs. Trunked maybe?

There are 3 frequencies. All seem to be used by the same operator. Might be trunked. There's one frequency where I never received any voice. Seems to be data and the the channel idling. I'll give recordings to the three frequencies. That might help narrow things down?

Probably some sort of linked wide coverage setup similar to IP Site Connect.

Thanks for the help! Also is it normal for linked setups to have voice in different frequencies at different times?

Not sure what you're asking. The radio traffic probably only shows up on repeaters that radios are currently using.
