What is Amateur Radio (Ham Radio)? Amateur radio is an amazing hobby that links licenced operators locally and around the world via radio waves and other modes.
Licenced operators (in Australia at least) have access to the most frequency assignments, second only to the defence force.
The hobby has a wide variety of interests both in its use and construction (if one desires), such as, radio, antennas, electronics, beacons, repeaters, satellites, testing equipment, integration of computers, software, making ones own gear like
electronic boxes to perform certain tasks, constructing antennas and many other items required to get on air. Once on air, some like to call
anyone for a chat (QSO), or contact others using digital modes via computer, or compete in radio contests to see how many persons and countries
one can contact during a defined time period. Some like setting up portable on a hill top using batteries, radio and a wire antenna thrown over a tree.
Disaster emergency communications provided by hams assist authorities in times of need. There is something within the hobby that would take your interest for sure.
Hopefully this 'ham talk' will help understand some of the jargon and information contained in this website.
