ARRL is the national -USA membership association for Amateur Radio operators. Amateur Radio (ham radio) is a popular hobby and service that brings people, electronics and communication together. People use ham radio to talk across town, around the world, or even into space..
The seed for Amateur Radio was planted in the 1890s, when Guglielmo Marconi began his experiments in wireless telegraphy.
Soon he was joined by dozens, then hundreds, of others who were enthusiastic about sending and receiving messages through the air–some with a commercial interest, but others solely out of a love for this new communications medium. The United States government began licensing Amateur Radio operators in 1912.
