KNIX-FM

Country music radio station in Phoenix

KNIX FM (102.5 MHz) is a commercial radio station in Phoenix, Arizona, owned and operated by iHeartMedia, Inc. The station airs a country music radio format. The studios and offices are located on East Van Buren Street in Phoenix near Sky Harbor Airport. The transmitter is in South Mountain Park, off Road B, amid other towers for Phoenix area FM and TV stations.

The station originally signed on the air on December 25, 1961. Because there was no associated AM station, the call sign was simply KNIX. It has kept the call letters KNIX or KNIX FM throughout its history. KNIX previously transmitted with 3,100 watts, a fraction of its current output, only heard in Phoenix and its adjacent suburbs. KNIX aired a beautiful music format. The license was held by Aztec Radio, Inc., with owners John and Donna Karshner also serving as on air staff and programmers. Their son, John P. Karshner II, became one of the youngest DJs in America at age 16.

In May 1968, country singer Buck Owens bought KNIX. The purchase documents used his formal name, Alvis Edgar Owens, Jr. In addition to KNIX, Owens acquired KYND AM 1580 in Tempe from a different owner. The year before, Owens had purchased an AM and FM station in Bakersfield, California, KUZZ AM FM, which had been a profitable move. Under Owens' ownership, the AM station in Phoenix became country music KTUF 1580, while 102.5 KNIX changed to progressive rock in August 1968. In early March 1969, KNIX FM switched to country and the power was dramatically boosted to 100,000 watts. KTUF and KNIX FM began simulcasting the country format, allowing listeners with FM radios to hear it in stereo, while the AM signal could be received on all other radios. Station bumper stickers proclaimed "K TUF/KNIX, We Stamped Out 3 Letter Radio." The bumper sticker referred to KOY AM 550, the leading radio station in Phoenix at the time, and the only one with a three letter call sign. In 1976, the AM call letters switched to KNIX, while the FM station added the FM suffix, creating KNIX AM FM. The AM station began programming classic country music, becoming the flagship station for a network called "Real Country." Meanwhile, KNIX FM concentrated on contemporary and recent country hits. AM 1580 KNIX ended its association with the Real Country Network in 1985 and the AM FM simulcast was restored. KNIX FM not only led the Phoenix radio market, but was considered one of the premier country radio stations in the United States. Under the leadership of Buck Owens' son, General Manager Michael Owens, and Programming/Operations Manager Larry Daniels, KNIX FM was consistently number one in Phoenix. It topped the market in all but one ratings period between 1980 and 1990.

In 1998 Clear Channel Communications acquired the FM station from Owens, while the AM station was sold to The Walt Disney Company. KNIX FM was sold for $84 million. The Disney Company used the AM station for its Radio Disney children's radio format, while KNIX FM kept its successful country format. On September 16, 2014, Clear Channel renamed itself iHeartMedia, Inc., to bring its corporate name in line with its iHeartRadio internet platform.

KNIX FM has won many prestigious awards in the country music and radio industry. They include honors from the Country Music Association, the Academy of Country Music, Billboard magazine, and the Marconi Award for excellence in broadcasting. The CMA honored KNIX FM as its "Major Market Station of the Year" in 2019, its sixth time receiving the award.

KNIX FM broadcasts in the HD Radio format. The main signal is a simulcast of KNIX's country programming. On April 25, 2006, Clear Channel announced that KNIX's HD2 subchannel would carry a format focusing on music from new and up and coming Country artists. Several years later, the HD2 subchannel began carrying the audio of co owned talk radio station KFYI 550 AM. The third channel carries iHeartMedia's Total Traffic Network (TTN), a data only service broadcasting real time traffic streaming to GPS devices with HD Radio receivers, providing accident, traffic flow, and road construction information. Devices capable of receiving traffic data are available from manufactures such as Garmin and Cydle.
