KGGO

KGGO has an effective radiated power (ERP) of 100,000 watts, the maximum output for non-grandfathered FM stations.

The station started broadcasting in FM stereo in December 1969 with a concert from the Boston Symphony Orchestra.

Longtime announcer Ron Sorenson hosted a late night program of progressive rock music called the "Roc Show," during the years KFMG was owned by the Plymat Family.

When the Woodland Corporation bought the station in 1969, Sorenson convinced the new owners to go with that format on a full-time basis.

Morning host John Krantz played the first song at 6 a.m. that day, "Colour My World," by Chicago.

The planned demolition of the Brown Hotel caused Woodland to seek a new studio and location for the antenna and transmitter.

A new location atop the Teachout Building did not give KFMG the coverage that it previously had from the Brown Hotel.

Stoner management soon found out that KFMG had a small but loyal listenership when they expressed displeasure over Sorenson's departure.

Stoner ran a full-page ad in the Des Moines Register to appease disgruntled KFMG listeners, but the station did not return to a rock format for several years.
