KWDF serves the Alexandria, LA area. KWDF began broadcasting in 1987 on AM 840, which is considered a clear channel frequency shared by only 17 other stations in the country. The KWDF signal covers two-thirds (thirty parishes) of the state of Louisiana which includes one-third of the population of the whole state. KWDF has been airing Gospel music and Christian teaching programs for almost 25 years. In 2008, Wilkins Radio purchased KWDF and continued the Christian format and expanded to an exclusive Christian talk station.
