KZIO (104.3 / 94.1 FM, "94X") is a radio station located in Duluth, Minnesota that airs an active rock format. Established in 1995 as WRSR, the station is owned by Red River Broadcasting, which also owns KQDS-TV channel 21, KQDS 1490 and WWAX-FM 92.1. The studios are located at Grandma's Marketplace in Canal Park in Duluth.


The main station, KZIO-FM which operates at 104.3 MHz, is based in Two Harbors, Minnesota — its moniker is derived from its Duluth translator (low-power rebroadcaster), K231BI which operates at 94.1 FM. 104.3 FM can be heard in Duluth, though its signal is spotty. The former active rock format signed on as "X106" using 106.3 as the translator until upgrading to 94.1 FM.

The call letters KZIO were originally located at what is now KDKE 102.5 MHz in the same market. 102.5 KZIO aired a Top 40 format in the 1980s and 1990s until switching formats in 1996.

104.3 began as WRSR with a smooth jazz format in September 1995[2] before transitioning to several adult-based radio formats until settling upon the active rock format in March 2003.

Over the years, 94X has aired some mainstream rock and classic rock music that is not typically a part of the active rock format in an effort to fend off rock-based formats at various competing stations.

Past and Present 94X DJ's include Zooch, Hans, The Kid, Ray, Ace Rockolla, The Milkman, Diesel, Smiling Mike, Alli Foxx, Todd Spoons and Skid Mark.

On February 27, 2017, Red Rock announced their intentions to sell KZIO and K231BI to Minnesota Public Radio for $300,000. It will convert the station to a non-commercial operation.[3] MPR confirmed late in March that the station would carry their The Current network in the market upon the sale's closing.[4][5]

The application to transfer the licenses was granted on April 24, 2017.
