Amateur radio, often called "ham radio," has its roots in the late 19th and early 20th centuries, closely tied to the development of wireless communication. Following the pioneering work of inventors like Guglielmo Marconi and Nikola Tesla, hobbyists and experimenters began using early radio equipment to explore the new technology. The first organized amateur radio activities emerged in the early 1900s. By 1912, the Radio Act in the United States formally regulated the spectrum, reserving frequencies for amateur use. Similar regulations soon followed in other countries. Early hams used crude spark-gap transmitters and Morse code to communicate over long distances, often proving the practical utility of radio waves. The 1920s and 1930s saw rapid advancements in technology and organization. The founding of groups like the American Radio Relay League (ARRL) in the U.S. and the Radio Society of Great Britain (RSGB) helped unify amateurs globally. By sharing knowledge and fostering a sense of community, these organizations promoted technical innovation and international goodwill. World War II temporarily halted amateur radio operations in many countries, as governments reserved frequencies for military use. However, many amateur radio operators contributed to the war effort by serving as radio operators or engineers. After the war, the hobby flourished again, with improved equipment and the allocation of additional frequency bands. The advent of satellites in the 1960s, starting with OSCAR-1 (Orbiting Satellite Carrying Amateur Radio), expanded amateur radio's reach into space. Digital modes, introduced in the late 20th century, revolutionized communication, allowing amateurs to use computers for efficient data transmission. Today, amateur radio is a global activity with millions of licensed operators in nearly every country. It serves as a platform for emergency communication, technical experimentation, and international friendship, preserving its legacy as a vital and dynamic hobby.
