They are turning on their radios pretty regularily from what i have seen, and i heard them using one of their radios during a pursuit that move up theri direction from Anoka County.
So far i have logged radio ID's 146009, 146013, 146037, 146056, 146062, 146063 and 146064 logging onto or using TG 3446 (Isanti Co 911) and 6000 (Isanti Co LE Disp)...
i think there are plenty more radios, i just havent logged them...
