The station is owned by the Best Broadcast Group and carries a hot adult contemporary format, primarily simulcasting KZBK 96.9 FM.
George P. Williams became the owner in 1965; W-H Enterprises acquired KGHM in 1970; and the station was sold to Brookfield Broadcasting in 1974.
Hampro ownership, while short, was consequential, as the company received the construction permit to build a new FM radio station to accompany KGHM.
