The Radio Amateur Civil Emergency Service is an organization of licensed amateur radio operators who volunteer their time and equipment to provide supplemental communication to local, county and state governments in times of emergency or natural disaster. RACES Nets are authorized by the Federal Communications Commission per Part 97, Subpart E and the local Emergency Management offices. A major function performed by RACES in the Dallas/Fort Worth area is providing information to the National Weather Service during periods of threatening or severe weather.

County wide RACES nets are authorized by the Dallas County Office of Homeland Security and Emergency Management, and the Federal Communications Commission per Part 97, Subpart E. Dallas County, the City of Dallas and the many cities in the county have their own RACES organizations. Each organization is independent of the others. However, all belong to the Dallas County RACES Council, cooperate in their basic requirements and provide mutual aide and support.
