KZON (103.9 FM) is a commercial radio station located in Phoenix, Arizona, broadcasting to the Phoenix Metropolitan Area. KZON airs a Hot AC format branded as "Hot 97.5/103.9" (simulcasting with KMVA 97.5 FM Dewey-Humboldt, Arizona). Its studios are located on 7th Street in Midtown Phoenix, while its transmitter is located in San Tan Valley, Arizona.

The station signed in 1981 and located in Coolidge, Arizona. The station aired a country music format and originally adopted the call letters of KQEZ. This lasted until 1994.

In 1994, the country music format was dropped in favor of a classic rock music format complemented by a change of call letters to KAZR. A signal upgrade followed providing the southern sections of the Phoenix, Arizona, area with a clear signal. However, the format change was short lived.

In March 1994, the format was changed to a modern rock/top 40 hybrid branded as “The Blaze”. A change of call letters to KBZR followed the change of format. In the Spring of 1996, the station began moving its transmitter closer to Phoenix. At the same time, the station began a 6-month stunt of an automated Rhythmic Oldies format, only going by the moniker "S.T.E.V.E." The name was an acronym standing for "Songs That Everyone Vociferously Enjoys."

On October 30, 1996, at 3:30 PM, the station completed its upgrade, and flipped to a hip-hop emphasizing rhythmic top 40 as "103.9, Arizona's Party Station". The call letters were changed in the spring of 1997 to KPTY to reflect their station branding. Despite the station's signal limitations, KPTY did very well in the ratings; in fact, rival KKFR, which was airing a broad-based Mainstream Top 40 format at the time, began to move towards a hip hop/R&B emphasizing rhythmic top 40 format as well, and took away much of KPTY's audience. In 1998, the format evolved to a hybrid hip-hop/modern rock format shortly followed by a change of branding to "Party Radio @ 103.9". During the last week of 1999, KPTY stunted a supposed broadcast hijacking with buzzing sounds and audio glitches in the songs, legal IDs, sweepers, and as the DJs were talking. On December 31, 1999, KPTY began stunting with a 24-hour loop of "We Like To Party" by The Vengaboys. On January 1, 2000, it returned to a rhythmic top 40 format (this time with more of a dance lean) as "103.9 The Party".
