I remember back in February last year there was some speculation that ARDOT may have gone to some other radio system, because there was little to no radio traffic on their VHF channels. Well, just today I heard some radio traffic for District 8 on 151.0550, DCS 411 talking about how the roads were beginning to ice up and more sand was needed. So at least in the Russellville area, I'm still hearing them on their VHF frequency.
