KJJK was one of two Fergus Falls FMs. Their format was Adult Contemporary. This aircheck clip is short, but it’s all I have. I grabbed it during an overnight dial scan while my antenna was aligned with the Fargo/Moorhead stations.
Equipment used was a Pioneer SX-3900 receiver, Winegard 10 element FM yagi antenna, Alliance U-100 Tenna Rotor, Belden ultra low loss RG59 coaxial cable, Sears stereo cassette deck, and a BASF 60 minute normal bias cassette.
