 KABG launched in Summer 1997 as "Big Oldies 98.5".It then went on to overcome two other long running oldies stations in the Albuquerque and Santa Fe markets, KBOM 106.7 (moved to 94.7 in 2000, both frequencies which AGM had later purchased) in Santa Fe and KZKL (later changed to KQEO) 101.7 in Albuquerque which dropped the format in 2002 making KABG the only FM oldies station in both markets until its format change in 2007.Local radio veteran Bobby Box would host the morning shift for several years helping to make the station popular with its target audience.
