Amateur radio is used in search-and-rescue, contests, disaster aid (hurricanes, earthquakes, tornadoes, floods, accidents, fires), and much more. Amateur radio operators talk with other HAM radio hobbyists using all sorts of communication modes.
From Morse Code and voice to Slow Scan Television and computer networking through the radio waves, these hobbyists reach out with goodwill from their homes, cars, boats and outdoors. Some also like to work on electronic circuits, building their own radios and antennas.
Dedicated hobbyists have pioneered in new technology, contributing to advances in technology that has impacted the world of communications in all areas of our lives. Even ham-astronauts take radios with them on space shuttle missions, and make calls to earth-bound Amateurs.
