According to Wikipedia, 92.9 FM in San Antonio offered a Rhythmic-leaning CHR format for over a decade, starting in 1979. Three days after this recording was made, the station flipped to an Adult Contemporary format branded as “Star 93” with the call letters KSRR. The aircheck includes mysterious sweepers hinting at an upcoming change. They were voiced by Jerry Clifton in a style nearly identical to what was heard six years later on KBZR in the Phoenix area, during that station’s “S.T.E.V.E.” stunt. The on-air personality was also referring to the station as simply as “93 KITY” or “KITY”.
