History

What is now KKRZ first signed on May 7, 1946 as KGW-FM on 95.3 MHz and moved to 100.3 MHz on September 22, 1947. The call letters changed to KQFM on December 1, 1954 and broadcast a beautiful music format known as "Q-Music", and then in 1978, switched to a pop/AOR format under the name "Q-100". The format was changed to oldies on March 16, 1981 as "Solid Gold FM-100". The station changed to the KKRZ call letters and changed to what is considered a Hot AC format as "The Rose" (hence the KKRZ call letters) on November 2, 1983. KKRZ began its current heritage Top 40 format on March 16, 1984, widely mirroring sister station WHTZ/New York City (down to the name "Z100").
