World Amateur Radio Day Is April 18

World Amateur Radio Day (WARD) is the birthday of the International Amateur Radio Union (IARU); the worldwide federation of national amateur radio organizations.

About IARU

The International Amateur Radio Union (IARU) is the worldwide federation of national amateur radio organizations. The membership of the IARU consists of more than 160 member-societies in as many countries and separate territories.

The IARU was founded at a meeting in Paris in 1925 as the international representative of the Amateur Radio movement. At the time the “short waves” were just beginning to be understood and to be exploited for global communication using power levels and antennas that were within reach of private individuals operating from their own homes. These radio amateurs needed an organization to coordinate their activities and to be their voice at international conferences. 4
