I have a list, but more than likely it is out dated.
1200 Young America
1400 Chaska PD
300 Fire
2700 Victoria Fire
2800 Chanhassen Fire
200 Fire
8800 Waconia Police
1000 Fire
This comes from a list , dated 1999. Collected them when I lived in Rochester, MN.
Unit Id's for Carter County, may have changed.
Hope this helps. Keep us posted here on RR if these are good Id's.
