The station was assigned the call sign "KRKX" on August 22, 1983. On February 28, 1988, the station changed its call sign to "KZRC". While having this callsign, it was affiliated with the radio network Z Rock, which played hard rock and heavy metal. It would remain affiliated with Z Rock until 1994.

In June 2010, owner Bustos Media (through its license-holding subsidiary Bustos Media of Oregon License, LLC) reached an agreement to transfer KOOR and several sister stations to Adelante Media subsidiary Adelante Media of Oregon License, LLC. The FCC approved the deal on September 3, 2010, and the transaction was consummated on September 24, 2010.[3]

In August 2010, KOOR began airing Russian language programming under the brand "Russian Radio 7".[4][5] The station previously broadcast a Spanish-language talk radio format branded as "W Radio 1010 AM".[6]

In June 2011, Adelante Media sold KOOR and three Portland, Oregon, area sister stations back to Bustos Media (through its license-holding subsidiary Bustos Media Holdings, LLC) for a combined sale price of $1,260,000. The FCC approved the transfer on August 16, 2011, and the deal was formally consummated on September 30, 2011.[7]

In November 2016, KOOR rebranded as "Наше Радио USA". However, as of February 2021, the station has reverted to a Spanish hits format, calling itself "Diez-diez AM", and imaging with the English phrase, "To The Max!".

On April 5, 2021 KOOR flipped to Spanish rhythmic top 40, branded as "Urbana", simulcasting on KXXP (104.5 FM).[8]
