WDWD
WDWD (590 AM) is a Christian talk station serving the metro Atlanta market. Its radio transmitter site, originally along North Druid Hills Road, is now located just north of Austell, Georgia, in west-northwest metro Atlanta. The station's signal is aimed by a four- tower directional antenna array from the Austell transmitter location towards Atlanta (and avoiding interference with WWLX). In 2009, the station upgraded daytime transmitter power from 5,000 to 12,000 watts, while the nighttime power remains at 4,500 watts. Also in 2009, the station started broadcasting in the AM HD Radio (hybrid digital) mode (which has been unavailable since 2013).
