Radiosport
The IARU organises and promotes radiosport activities throughout the world. The rules used for High Speed Telegraphy are maintained by a Working Group of the IARU, and regional and world championships in the sport are sponsored by the IARU. Amateur Radio Direction Finding is similarly supported by the organisation, with a standing Working Group responsible for maintaining the rules used by most international events, including IARU-sponsored regional and world championships. The IARU is less directly involved in the sport of contesting, but does sponsor an annual competition known as the IARU HF World Championship. The IARU does not directly administer any of these sporting events, but authorises and sponsors them through host organisations.
