The transmitter site is on NE Marine Drive in the northeast side of Portland along the Columbia River.[5] KFXX is a Class B radio station. By day, it runs the maximum power for commercial AM stations in the U.S., 50,000 watts, audible around much of northwest Oregon and southwest Washington. At night, because AM 1080 is a clear channel frequency, KFXX must reduce power to 9,000 watts, so it does not interfere with co-owned KRLD in Dallas and WTIC in Hartford, the two dominant Class A stations on the frequency. KFXX uses a directional antenna at all times.
Programming
KFXX is a network affiliate of ESPN Radio but mostly runs its own local shows on weekdays. Its sister station, 910 KMTT, carries the ESPN Radio lineup around the clock. As of March 1, 2021, KFXX starts the day at 6 a.m. with "Dirt and Sprague" in morning drive time. At 9, it carries Colin Cowherd from the Fox Sports Radio Network. At noon, KFXX airs "Danny and Dusty". Followed by "Primetime with Isaac Ropp and Jason 'Big Suke' Scukanec" is heard on weekday afternoons from 3 to 7 pm.Primetime from 3-6 is mostly sports related. The last hour of the show is funny stories from mostly current events or news happening around the world.[6] The first three hours of "Primetime" were simulcast on the Comcast SportsNet Northwest cable TV network. Nights and weekends, KFXX runs programming from ESPN Radio when it isn't airing a live sports event.
History
Early years
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.[7]
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.[8] 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.[9] It was only powered at 3,400 watts and it mostly simulcasted the AM station. However, in the 1940s and 1950s, few radios could receive FM signals and management saw little opportunity to make it profitable. In the mid 1950s, KWJJ silenced the FM station, giving up the license. Another station signed on at 95.5 in 1959, which is today KBFF.
Switch to Country
KWJJ was acquired by Rodney F. Johnson in 1952. Johnson served as president and general manager as well. KWJJ became Portland's ABC RadioNetwork affiliate in 1959 and adopted a country music format on March 1, 1965.[10] 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.[11] A year later, Park acquired 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."[12] 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 simulcasted the morning show and some other segments during the day.
In 1996, Seattle-based Fisher Communications bought KWJJ-AM-FM for $35 million.[14] Fisher continued the country format on KWJJ-FM, while making plans to change the AM station.
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.[16] 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.[17]
