KABG (98.5 MHz) is an American radio station licensed to Los Alamos, New Mexico serving the Santa Fe and Albuquerque radio markets. It is owned by American General Media and has a classic top 40 classic hits format playing hits mostly from the 1960s to the 1980s. Its studios are located in Northeast Albuquerque and the transmitter tower is located west of Los Alamos, New Mexico.
The format 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.
For many years the station had been known as "Big Oldies" but in 2007 it rebranded to just "Big 98.5" phasing out the word "oldies" as it has followed most other oldies stations across the country in shifting to a more 1970s focused "classic hits" format in order to improve its audience in the 25-54 age range demographic. It has also changed its website. Despite this, the station still played a small amount of 1950s/early 1960s oldies. As of 2015 the format is mostly focused on music from the 1980s with a small amount of music from the 1990s added.
