The general manager of Kansas Public Radio and director of the Kansas Audio-Reader Network announced Tuesday that she will retire from those positions on September 2. Janet Campbell began working at Audio-Reader in 1979 as a secretary; she became director of the network in 1988. She was named general manager of KANU-FM in 1998. KANU was renamed Kansas Public Radio in 2002. KPR's director of engineering, Steve Kincaid, will serve as interim director of both entities while a national search is conducted for a replacement.
