Owned by iHeartMedia, Inc. (formerly Clear Channel Communications), its studios are located in Northeast Albuquerque and the transmitter tower is atop Sandia Crest east of the city.

[2] The Peak features Jackie, Tony & Donnie in the morning; local personality Ryan in middays; Randi West, who originates at WMTX in Tampa, Florida, in afternoons; and Haze from KMYI in San Diego, California, at night.

Initially, KPEK aired a modern adult contemporary format built on the popularity of artists such as Hootie & the Blowfish, Counting Crows and Alanis Morissette.

By 2003, KPEK would bring on Tony & Jackie, who had been heard on local top 40 stations KKSS, KCHQ, and KKOB-FM in past years, for mornings.

The Peak had often featured a large selection of 80's music that it termed "Tainted 80's" for much of the first 15 years of the station's run.
