Mutual Aid Freqs...

Can anybody help me figure out the freqs for the statewide 'Mutual Aid' 'Inter-agency' frequencies? Once upon a time I had 2 freqs for this... one had traffic, the other had none.



I live in Benton County so I'm most interested in Benton, Iowa, Powesheik, and Tama counties (but I don't think that matters). I would think it would have to be analog as not all agencies have digital capability).



Any info would be much appreciated... Thanx!
