KDND (107.9 MHz) was an FM radio station licensed to Sacramento, California, United States. The station first signed on in 1947 as KXOA-FM, an FM simulcast of AM station KXOA, before separating itself with distinct programming, including most prominently soft rock, adult contemporary, and classic hits formats. In July 1998, two years after the sale of the station to Entercom (now Audacy, Inc.), the station switched to its final KDND call letters and Top 40/CHR format branded as 107.9 The End. At the time of the station's closing, KDND's studios were located in North Highlands (though with a Sacramento address), while its transmitter was located just north of the Sacramento city limits near Elverta. In January 2007, KDND's morning show controversially held an on-air contest in which contestants were challenged to drink as much water as they could without urinating, in order to win a Nintendo Wii video game console. A 28-year-old participant in the contest died of water intoxication, resulting in Entercom being sued for wrongful death by the participant's family. The Federal Communications Commission (FCC) also investigated the incident; in 2016, it designated the renewal of KDND's license for hearing, questioning whether the station had operated in the public interest. Citing that its continued operation could affect Entercom's proposed acquisition of CBS Radio, KDND was shut down on February 8, 2017, and its format and branding were moved to KUDL two days earlier on February 6. The FCC auctioned the frequency in 2021; iHeartMedia won the bidding, and KSTE-FM (now KZIS) began broadcasting on May 4, 2022. As KXOA-FM Early years On September 25, 1945, Lincoln Dellar, who had signed on KXOA (1470 AM) on May 20 of that year, applied to the FCC to build a new FM radio station in Sacramento, originally specifying 95.9 MHz as the frequency. The construction permit was granted on December 19, 1945, but changes in program planning and technical adjustments in the early days of the present 88–108 MHz band meant that the station debuted at 102.9 MHz in June 1947 before being moved to 107.9 MHz within months. For most of this time, KXOA simulcast the AM station, which since its launch had been an affiliate of the Mutual Broadcasting System. In July 1957, KXOA dropped Mutual to become a Top 40-format music station; later that year, the KXOA stations were sold to Cal-Val Radio. In 1961, Cal-Val experimented with
