96.7 & 105.5 are "Star"
98.3 & 102.3 are "Free Country"

Following this pattern, I agree that 100.7 & 95.1 are probably next in line to be joined. But I also think 95.9 will be added to that group to make one big "River" or a Classic-Hits tweaked "Will-Rock" trimulcast. There is some distance between 100.7 and 95.9. Back in the 90's they used to carry the same satellite-fed oldies programing (WKKD/WKBM).

I wonder how long before they dump their AM signals.
