Hot 100 FM is a commercial radio station located in Burley, Idaho, broadcasting to the Twin Falls, Idaho, area. KZDX airs a hot adult contemporary music format. On September 12, 2011, after years of playing a pop/Modern Rock hybrid as 99.9 the Buzz, KZDX tweaked to a more conventional Hot AC format. The station is now known as the new Hot 100. The station still airs Rick Dees and Absolutely 80's on the weekends. At night the station leans more CHR by adding some Rhythmic product to compete against rival KTPZ.
