Rock 103 was an interesting station. I first became acquainted with them a few years earlier when I worked radio in Fort Dodge. Although they used a “Rock” identifier, they were really a hybrid CHR/AOR. This aircheck is a great example: you’ll hear them go from Chicago’s “Along Comes a Woman” to Transvision Vamp! Seemed to work for them, though.
This is either evenings or overnights. Can’t remember for sure which daypart. I grabbed it from Apple Valley, MN, using a Pioneer SX-3900 receiver, Winegard 10 element FM yagi, Alliance U-100 Tenna Rotor, and Belden RG59 ultra loss coaxial cable. A Sears stereo cassette deck and BASF 60 minute normal bias tape captured the recording.
