KHXM is powered at 250 watts from a non-directional transmitter near Mililani Cemetery Road in Pearl City.
It later switched its call sign to KIPA and KIFO, a news/talk outlet operated by Hawaii Public Radio from 1990 to 2002.
It used programming from Fox Sports Radio around the clock but with plans to include local content eventually.
This type of competition is unusual, especially in a market with no major professional sport teams, in part due to geographical and financial reasons.
While rock music is not usually heard on the AM band, the station feeds and images itself around its two translators, 103.9 in Waipahu and 104.7 in Haleiwa.
