Owned by iHeartMedia, the station serves as an analog simulcast of KUCD-HD2, KUCD's HD Radio subchannel, carrying an alternative rock format.

The license to this station was granted on July 30, 2007, as a retranslator for KDNN, airing traditional Hawaiian music as "Hawai’i No Ka Oi" (translated as "Indeed the Best").

Local radio personalities Lanai and Augie (previously of main KDNN station) hosted their own morning talk show Weekdays from 6 to 9AM.

The station's new format predominantly features K-pop (including collaborations with U.S. artists), as well as other Chinese, Filipino, and Japanese acts.
