99.9 FM KFAV serves the St. Louis Westplex, which includes what has been recognized as some of the fastest growing counties and communities in the United States. We serve St. Charles, Lincoln, and Warren Counties primarily, however we also have a listenership in Franklin, Gasconade, Montgomery, and St. Louis Counties.

Our track record and constant goal has been to serve the cities of St. Charles, St. Peters, O'Fallon, Lake St. Louis, Wentzville, Troy, Winfield, Silex, Moscow Mills, Wright City, Warrenton, and Washington, Mo. With 10 local newscasts each Monday through Friday, local sports information, live broadcasts, and promotion of Westplex events and local fairs, KFAV offers more than other St. Louis metro radio stations when it comes to serving our area.

Since 1991, KFAV has been dedicated to the phrase "Serving The Westplex!"
