In December 1949, the station first signed on as KLMO, originally at 1050 kHz.[2] It was a 250-watt daytimer, required to be off the air at night, and owned by the Longmont Broadcasting Company. In 1965, it shifted to 1060 kHz, and in the 1970s increased its power to 10,000 watts, but still daytime only. In the 1980s, KLMO received Federal Communications Commission approval to broadcast around the clock, but with only a small amount of power at night.
The station aired a full servicecountry music format for Longmont and the northern suburbs of Denver. On March 22, 2000, the Radio Colorado Network was launched. The station's format switched to Business and Personal Finance programming, targeting the Denverradio market.
