When KNZA Inc. closes on its acquisition of KTNC-AM in Falls City NE, it will have created three separate AM-FM combos. The group, which lists Gregory F. Buser, Robert B. Hilton and William Douglas Weinberg III as principals, owns three FMs in the area which do not overlap one another, but all of which share a piece of KTNC's coverage area. The group includes KNZA-FM Hiawatha KS, KMZA-FM Seneca KS and KLZA-FM, which shares KTNC's Falls City hometown. The seller is Charles Radatz's C.R. Communications, which will get 330K for the station.
