I would think the Talkgroups are correct. I’m to far away to help. Maybe blantonl can chime in since he spends time in Whitefish or somebody else local can confirm Talkgroups for Kalispell.
The data for Flathead County is all correct. Not sure what scanner your using but they have multiple sites in the area that you should have programed in your scanner and yes one is 800mhz site.
