KWYZ

On April 1, 1962, the station was acquired by the Snohomish County Broadcasting Corporation, with Cliff Hansen as president and George Aller as vice president. The new owners had the FCC change the station's call sign to KWYZ. In June 1974, the new owners dropped the station's middle of the road music format in favor of country music.

Facing a petition to deny its license renewal and a financial crisis, the broadcast license for KWYZ was involuntarily transferred in November 1991 from Prime Time Broadcasting, Inc., to Richard D. Carlson acting as receiver. The transfer was approved by the FCC on November 14, 1991. In June 1992, receiver Richard D. Carlson reached an agreement to sell this station to Quality Broadcasting Corporation. The deal was approved by the FCC on March 29, 1993, and the transaction was consummated on June 28, 1994.

In March 1999, Quality Broadcasting Corporation agreed to sell KWYZ to Jean J. Suh, doing business as Radio Hankook, for a reported price of $480,000. The deal was approved by the FCC on April 27, 1999, and the transaction was consummated on August 3, 1999. Until this deal was consummated, KWYZ maintained its traditional country music format. Suh applied to the FCC in October 2002 to transfer the broadcast license for this station to her company, Radio Hancook, Inc. The transfer was approved by the FCC on November 15, 2002, and the transaction was consummated on December 1, 2003. Jean J. Suh worked for five years as an actress as South Korea's Korean Broadcasting System before emigrating to the United States in 1964. While studying at Columbia College Hollywood in 1965, Suh began hosting a 30 minute weekly program of music and news in Korean on a Los Angeles radio station. In 1966 the program was extended to one hour per week and in 1967 to two hours each weekday. In 1970, Suh and two financial partners launched an independent Korean language radio station in Los Angeles, the first in the United States. The NAACP claimed each of the stations had "poor minority hiring records" and were in violation of equal employment opportunity laws.

Faced with mounting debts and financial difficulties, Radio Hankook owner Jean J. Suh moved KWYZ and sister station KSUH out of their rented studios in a commercial area of Federal Way, Washington, to her private residence in May 2000. This move brought on complaints from neighbors, visits from city code enforcement officers, and a public campaign by Radio Hankook to force the city to allow the studios to remain in Suh's home.

During a series of inspections conducted by FCC agents from March 2001 to November 2001, they found that KWYZ had failed to "have operational Emergency Alert System (EAS) equipment" and "to conduct required monthly and weekly EAS tests" and had failed to "post the ASR number on or near the base of" its broadcast tower in violation of FCC rules as well as finding similar violations by sister station KSUH. The FCC issued a "notice of apparent liability" against Suh for violations by KWYZ and KSUH on August 28, 2002, for a combined total of $22,000. After determining that Suh did not in fact own the KSUH tower, they reduced the penalty to $10,000 in late August 2003.
