KRSK (1080kHz "105.1 The Fan") is acommercialAM radio station inPortland, Oregon. It is owned byAudacy, Inc. and runs asports radioformat.[3] The studios and offices are on SW Bancroft Street in Portland.[4]
KRSK is one of four sports stations in the Portlandradio market, the others being co-ownedKMTT,KPOJ (owned byiHeartMedia) andKXTG (owned byConnoisseur Media).
Thetransmitter site is on NE Marine Drive in the northeast side of Portland along theColumbia River.[5] KRSK is aClass 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 northwestOregon and southwestWashington. At night, becauseAM 1080 is aclear channel frequency, KRSK must reduce power to 9,000 watts, so it does not interfere with co-ownedKRLD inDallas andWTIC inHartford, the two dominant Class A stations on the frequency. KRSK uses adirectional antenna at all times.
KRSK is anetwork affiliate ofESPN Radio but mostly runs its own local shows on weekdays. Itssister station, 910KMTT, carries the ESPN Radio lineup around the clock. As of July 22, 2025, the station starts the day at 6 a.m. with "Dirt and Sprague" in morningdrive time. The 9-noon period is currently in transition, as the station's long-time carriage ofThe Herd with Colin Cowherd has recently ended, the program moving toFox Sports Radio affiliateKPOJ.[6] At noon, KRSK airs "Danny and Dusty". "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.[7] The first three hours of "Primetime" weresimulcast on theComcast SportsNet Northwest cable TV network. Nights and weekends, KRSK runs programming from ESPN Radio when it is not airing a live sports event.
This station was first licensed as KFWV, whichsigned on the air on October 12, 1925. In 1927, thecall 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 kHz in the daytime, 1040 kHz at night.[8]
After the enactment of theNorth American Regional Broadcasting Agreement (NARBA) in 1941, KWJJ moved to its current position on the dial, at 1080 kHz.[9] 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 95.5MHz.[10] It was only powered at 3,400 watts and it mostlysimulcasted 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 todayKBFF.
KWJJ was acquired by Rodney F. Johnson in 1952. Johnson served as president and general manager as well. KWJJ became Portland'sABC RadioNetwork affiliate in 1959 and adopted acountry music format on March 1, 1965.[11] 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 byPark Communications.[12] A year later, Park acquired KJIB, an FM station airing abeautiful music format. For the first years of Park ownership, KJIB remainedeasy listening and KWJJ remained country. In the late 1970s, Park moved KJIB from mainstream easy listening to a new format known as "Beautiful Country."[13] 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 itsplaylist of country tunes. On August 19, 1985, KJIB changed itscall sign to the currentKWJJ-FM. The two stationssimulcasted the morning show and some other segments during the day.
KWJJ dropped its simulcast of KWJJ-FM in 1995, becoming anetwork affiliate forABC's "Real Country," aclassic country service.[14]
In 1996,Seattle-basedFisher Communications bought KWJJ-AM-FM for $35 million.[15] Fisher continued the country format on KWJJ-FM, while making plans to change the AM station.
On October 27, 1997, KWJJ's call sign was switched to KOTK, and flipped to a "hot talk" format as "Hot Talk 1080 KOTK."[16] Fisher added several sports play-by-play broadcasts to the station, includingWashington Huskies football andbasketball,Portland Pilots basketball andPortland Forest Dragons football.
The KFXX call letters were first used in the Portland market on "The X", anactive rock station on1520 AM. KFXX flipped to its current sports format on September 1, 1990.[17] KFXX and its sports format moved to AM 910 on March 29, 1998, swapping frequencies with adult standards-formattedKKSN. The station again swapped frequencies, this time with hot talk-formattedKOTK on March 19, 2004.[18]
In its early days as a sports station, one of KFXX's hosts wasNeil Lomax, a formerquarterback atPortland State University and theSt. Louis/Phoenix Cardinals.
In 2003, Fisher Communications sold KOTK and KWJJ-FM toEntercom for $44 million.[19]
On July 24, 2025, Audacy filed to move the call sign KRSK from itssister station at 105.1 (which began simulcasting its sports format) to 1080 AM, with the station at 105.1 adding the -FM suffix to the existing KRSK call sign on FM, effective August 14, 2025.[20]
