On July 1, 1983, the station first
signed on as
KNAA. It was owned by Donald S. Beck, who served as its General Manager, Sales Manager and Program Director. The station broadcast at only 300 watts and carried an adult contemporary format. It was later sold to Johnson Broadcasting, which also owned
AM 1270 KPLY (now
KBZZ). The format remained adult contemporary but the
call sign changed to
KKMR. In 1993, the station changed call letters to
KNDE, airing a
soft rock format. In March 1998, the station was acquired by Salt Broadcasting, which already owned 100.1
KTHX-FM, an
adult album alternative station also serving the Reno
media market. Salt Broadcasting switched 100.9's call letters to
KRZQ, and began airing an
alternative rock music format, branded as "Reno's New Rock Alternative." At 12 noon on September 12, 2011, KRZQ changed to a
hot adult contemporary format. KRZQ began calling itself "Reno's Best Music Mix" and "Mix 100.9." The change in format did not result in immediate job losses, as many personalities started simply using different names. The
hot adult contemporary was designed to fill the void from when
KLCA dropped it for
contemporary hit radio by July
2011. On September 28, 2011, KRZQ changed call letters to
KMXW, to go with the "Mix 100.9" branding. On June 20, 2014, following KURK 92.9's sale to the
Educational Media Foundation, it was announced that KMXW would adopt the
classic rock format heard on KURK. It would become "100.9 The Bandit" once the sale was completed. KURK 92.9 then flipped to EMF's
Air 1 Contemporary Christian music network. (It has since become
KLRH airing EMF's
K-Love network.) On August 1, 2014, the
KURK call sign moved to 100.9 FM. In 2016, KURK rebranded as "100.9 K-Rock" and flipped to a broad mainstream rock format, playing fifty years of rock, trying to take on all of Reno's other rock stations at once. The station used a "shut up and rock" approach, limiting DJ chatter to stress its music commitment. On February 15, 2017, KURK changed its call letters to
KRFN. That was followed on March 7, 2017, with a switch from mainstream rock to adult contemporary, branded as "Fun 101". ==KRFN-HD2==
