KELO signed on as KGSS on 1200 kHz in October, 1937. It moved to 1230 kHz in 1941 as a result of the NARBA agreement. It moved to its current frequency May 2, 1948, and concurrently increased its power from 250 W to 5 KW.
KELO was a Top 40 station from approximately the 1960s through the 1980s, and then became an oldies/classic hits hybrid by the 1990s. The station flipped to its current talk format in July 2000.
