KFXX (AM)

This station was first licensed as KFWV, which signed on the air on October 12, 1925. In 1927 the call sign was changed to KWJJ, incorporating the initials of the station's founder, Wilbur J. Jerman. In the 1930s, KWJJ was powered at 500 watts, heard on 1060 kilocycles in the daytime, 1040 kilocycles at night.[4]

After the enactment of the North American Regional Broadcasting Agreement (NARBA) in 1941, KWJJ moved to its current position on the dial, at 1080 kHz.[5] The power was boosted to 1,000 watts. By the late 1940s, the power increased to 10,000 watts.

In 1946, KWJJ added an FM station, KWJJ-FM at 95.5 MHz.[6] It was only powered at 3,400 watts and it mostly simulcast the AM station. But in the 1940s and 50s, few radios could receive FM signals and management saw little opportunity to make it profitable. In the mid 50s, KWJJ silenced the FM station, giving up the license. Another station signed on at 95.5 in 1959, which is today KBFF.

KWJJ was acquired by Rodney F. Johnson in 1952. Johnson served as president and general manager as well. KWJJ became Portland's ABC Radio Network affiliate in 1959 and adopted a country music format on March 1, 1965.[7] In the 1970s, the station's daytime power was increased to 50,000 watts, while it continues to operate at 10,000 watts at night.

In 1973, KWJJ was acquired by Park Communications.[8] A year later, Park acquired 99.5 KJIB, an FM station airing a beautiful music format. For the first years of Park ownership, KJIB remained easy listening and KWJJ remained country. In the late 1970s, Park moved KJIB from mainstream easy listening to a new format known as "Beautiful Country."[9] The sound was soft, but used instrumental cover versions of Country songs, rather than Pop songs. With KWJJ as Portland's top country music station, management thought a beautiful country format on the FM station would be attractive to the AM station's advertisers.

KJIB switched to a conventional country format in the early 1980s. The FM station played mostly contemporary country hits with only a small amount of DJ chatter, while the AM station continued as a personality country outlet, going back several decades for its playlist of country tunes. On August 19, 1985, KJIB changed its call sign to the current KWJJ-FM. The two stations simulcast the morning show and some other segments during the day.

AM 1080 KWJJ dropped its simulcast of KWJJ-FM in 1995, becoming a network affiliate for ABC's "Real Country," a classic country service.[10]

In 1996, Fisher Communications bought KWJJ-AM-FM for $35 million.[11] Fisher owned radio and TV stations in Seattle and other Pacific Northwest cities. Fisher continued the country format on KWJJ-FM, while making plans to change the AM station.

On October 27, 1997, AM 1080's call sign was switched to KOTK, and flipped to a "hot talk" format as "Hot Talk 1080 KOTK."[12] Fisher added several sports franchises to the station, including Washington Huskies football and basketball, Portland Pilots basketball and Portland Forest Dragons football.

The KFXX call letters were first used in the Portland market on "The X", an active rock station on 1520 AM. KFXX flipped to its current sports format on September 1, 1990.[13] KFXX and its sports format moved to AM 910 on March 29, 1998, swapping frequencies with adult standards-formatted KKSN. The station again swapped frequencies, this time with hot talk-formatted KOTK on March 19, 2004.[14]

In its early days as a sports station, one of KFXX's hosts was Neil Lomax, a former quarterback at Portland State University and the St. Louis/Phoenix Cardinals.

In 2003, Fisher Communications sold KOTK and KWJJ-FM to Entercom for $44 million.[15]
