WCNN (680 kHz) is an AM radio station licensed to North Atlanta and serving the Atlanta-area radio market. It is owned by Dickey Broadcasting and airs a sports radio format. The station is commonly known by the on-air branding as "The Fan". Local sports shows are heard weekdays with the ESPN Radio Network airing nights and weekends. WCNN is the flagship of the Atlanta Braves Radio Network. WCNN broadcasts with a power of 50,000 watts during the daytime, and 10,000 watts at night, using a directional antenna at all times to protect other stations on AM 680 including KNBR from San Francisco. WCNN's transmitter and towers are located near Norcross, Georgia, northeast of Atlanta. WCNN is also heard on a 250-watt FM translator, W229AG at 93.7 MHz. The station formerly broadcast the audio portion of the CNN Headline News channel (hence its current call sign), an all-news radio format that the station pioneered in the 1980s and re-appeared on the station later in the station's history. History On September 1, 1965, the station signed on as WRNG, Atlanta's first talk radio station. The last three letters of the call sign represented the station's branding as "Ring Radio," as in the ringing of a telephone. The station was originally a daytimer operating at 5,000 watts but having to sign-off at night. It was the first broadcast home of talk radio personality Neal Boortz, who went onto a long career at WSB and syndicated nationally. Other, now well known talk radio personalities were also heard on the station, including Ronn Owens, later at KGO in San Francisco, Southern Humorist Ludlow Porch, and Barry Young, later at KFYI in Phoenix. In 1982, the station began an experiment by broadcasting the audio feed of CNN Headline News. The call letters were changed to WCNN, a nod to CNN's headquarters being in Atlanta. In February 1987, the station switched to an adult standards radio format and changed its call letters to WGTW. Its call sign was a reference to the Atlanta-based classic movie Gone with the Wind, which, coincidentally, is the favorite movie of CNN founder Ted Turner. The station went by the branding "Stardust 680" during that time. The radio format failed to gain ratings in the market. In late 1988, chief engineer Bob Mayben and his staff built elaborate studios in the CNN Center (formerly known as The Omni) and became WCNN "All
