KWNG was one of several 105.5 stations I could receive by turning the rotor and swinging the antenna around. They were only 3,000 watts at this time, long before the 1989 upgrade to 25,000 watts on 105.9. Their sister station KCUE was live, but KWNG was fully automated with the old “cart Carousel and reels” system. Sometimes, the automation would fail to fire the next source, resulting in dead air. You can hear an example on this aircheck.
Equipment used to receive this from Apple Valley, Minnesota was a Pioneer SX-3900 receiver, Winegard 10 element FM antenna, Alliance U-100 Tenna Rotor, and Belden RG59 ultra low loss coaxial cable. The recording was made to a Technics stereo cassette deck with Scotch Dynarange 90 tape.
