Despite being a R&B station going back to the late 1950s, there’s really not much written history for this 5,000 watt AM station. We do know that the station was known in the 1960s and 70s as “Soul 16”, as evidenced by the header on a scanned top 20 playlist sheet posted below. Contributor Bob Buchhauser did send along his liner notes:
KATZ – an urban mainstay in St. Louis flirts with disco on this air check. As you can tell, AM1600 is heavily day parted. Bennie & the Jets? Great jingles. TM Shotguns if I remember correctly.
This aircheck is from sometime in 1979.
