Signed on the air as KRRB in 1983 with an AC format, KZRX signed on in 1998, after Roberts Radio bought the station from Roughrider Broadcasting. KZRX went under a short lived moniker, aliasing themselves as "92.1 The Point"; and later as "Z92", starting back in the spring of 2001. The station ran a Hot AC format, then a mainstream rock format. For the first time since the frequency's original launch, back in 1983 (as KRRB), Z92FM broadcast 24 hours a day.
