KFUM was the call sign of Colorado Springs’ first commercial radio station.
The station was licensed in September 1922, making it one of the earliest broadcasters in Colorado. It later became KVOR, an identity that would remain central to Colorado Springs radio for decades.
The physical frequency used by KVOR changed over time, but the historical lineage of the KVOR identity begins with KFUM.
Call-sign lineage: KFUM → KVOR.
