I'll be honest, I don't pick DeKalb & Lagrange like I used to so I will defer to someone in Indiana to answer that. I do know that ISP in Ft Wayne & the Indiana Toll Road is on SAFE-T. I'll have to retract what I said in my last post, Branch, Hillsdale, & Williams are VHF for sure. OSHP Post 20 & Ohio Turnpike are on MARCS. Hope this helps some.
