Here’s a very short aircheck clip of the “Stereo Country K100” jingle which was used by KVOX-FM in the early 1980s. I caught this by accident during a routine dial scan. The antenna just happened to be correctly positioned to null co-channel KAUS-FM in Austin, Minnesota.
This was received from Apple Valley, Minnesota, using a Pioneer SX-3900 receiver, Winegard 10 element FM yagi antenna, Alliance U-100 Tenna Rotor, and Belden RG59 ultra low loss coaxial cable. The recording was made on a Technics stereo cassette deck with Scotch Dynarange 90 tape.
