KOOR (1010 AM "Urbana 1010") is a commercial radio station licensed to Milwaukie, Oregon, and serving the Portland metropolitan area.
But because 1010 AM is a Canadian clear channel frequency, at night it must go off the air to avoid interference.
On August 13, 1999, it changed again to "KGUY" (sports and pop-culture talk), and on March 15, 2004, to KZNY.
The FCC approved the transfer on August 16, 2011, and the deal was formally consummated on September 30, 2011.
However, as of February 2021, the station has reverted to a Spanish hits format, calling itself "Diez-Diez AM" ("Ten-Ten AM"), and imaging with the English phrase, "To The Max!".
On April 5, 2021, KOOR flipped to Spanish rhythmic contemporary hits, including Reggaeton music.
