KDZA simulcasts a classic hits format with sister station KQSC Colorado Springs.
The stations air classic recordings of the Wolfman Jack Oldies Show on Saturday evenings.
The station signed on in February 1948, and from around 1962 until the mid-1980s was Pueblo's leading AM Top 40 outlet.
In 1993, the station became KKPC and was operated by Pueblo Community College, airing Colorado Public Radio's news and talk programming.
[2] On May 18, 2023, a month after returning to its original call sign (which had been used on 107.9 FM and then 1350 AM after being dropped from this station in 1993), KDZA changed its format from adult hits to classic hits, branded as "101.9 KDZA".
