Amateur radio operators who transmit over their frequencies are called ham radio operators. The origin of the term is unknown. Ham radio is noncommercial, two-way transmission in which messages are sent by Morse code or by voice or data. Interest in amateur transmitting arose as soon as the radio was invented by Guglielmo Marconi. Because amateur transmissions interfered with low-wave transmission of commercial and military communication, the United States government instituted controls in 1911. Ham radio enthusiasts were limited to the use of short-wave frequencies, which at the time was deemed to have limited potential. After World War I, however, amateurs became active in experimenting, and by 1923 some operators achieved successful transatlantic transmission over short waves. Over the years amateur radio operators have provided emergency communication during natural and other disasters.  Amateurs are now able to use communications satellites to assist in making contacts.
