The station signed on the air on March 1, 1963. The original
call sign was KUMU. In 1967, it added an FM sister station.
KUMU-FM 94.7 MHz. For much of the 1960s, 70s and 80s, the two stations aired a
beautiful music format. Airing quarter-hour sweeps of mostly instrumental
cover versions of popular adult hits, as well as
Broadway and
Hollywood show tunes. In the 1990s, to appeal to a younger audience, the stations added more soft vocals and reduced the instrumental music. In the early 2000s, KUMU had an
adult standards format. A few years later, it flipped to
sports talk as a
network affiliate of
Sporting News Radio. In 2010, KUMU once again became a
simulcast of KUMU-FM, airing its
Rhythmic Adult Contemporary format. On August 2, 2010, Ohana Broadcast Company, LLC, sold KUMU 1500 to Blow Up, LLC, for $250,000. On September 30, 2010, the call sign was changed to KHKA and it returned to a sports talk format. In April 2013, KHKA rebranded as
NBC Sports Radio 1500 AM. On January 1, 2019, KHKA became an affiliate of
CBS Sports Radio as a result of NBC Sports Radio discontinuing its full-time network programming. By May 2020, KHKA rebranded as "CBS 1500" as it added programming from
CBS News Radio and
Hawaii News Now to the lineup while retaining CBS Sports Radio programs. ==References==
