KLUU has an effective radiated power (ERP) of 100,000 watts (horizontal polarization) and 86,490 watts (vertical polarization).^ It may be operating on an auxiliary power of 85,000 watts ERP. The transmitter is off Palehua Road, amid the towers for other Honolulu-area FM and TV stations. It also operates FM translator stations on 104.7 in Haleiwa and 105.5 in Honolulu.

Under Kona Coast Radio, KLUU applied for a construction permit as KKHI in February 2005 (superseded by a September transaction that same year), and became a variety station owned by Vic Michael of Kona Coast which officially signed on in 2007.

In October 2005, the call sign changed from KKHI to KHAI. In March 2007, Kona Coast sold KHAI to the Educational Media Foundation, which began running its Air1 service, which eventually was switched over to K-love. KHAI obtained the present KLUU callsign from K-love's Jamestown, North Dakota affiliate KJKL in 2015.

KLUU broadcasts using HD Radio technology.

KLUU programming is also carried on a broadcast translator station to extend or improve the coverage area of the station.
