History Of Amateur Radio

Post date: Jul 31, 2013 2:13:46 PM

Throughout the history of amateur radio, amateur radio enthusiasts have made significant contributions to science, engineering, industry, and social services. Research by amateur radio operators has founded new industries,[1] built economies,[2] empowered nations,[3] and saved lives[4] in times of emergency.

Amateur radio is a hobby and, by law, completely non-commercial. Individual amateur "ham" radio operators pursue the avocation for personal pleasure through building their own radio stations and communicating with their fellows globally, and for self-improvement via study and practice of electronics, computers, and radio and TV wave behavior. Radio amateurs are, thus, "amateurs" in the true sense of the word: pursuit of an activity only for the love of it. Radio amateurs can not broadcast or transmit music and other general public entertainment programming. The amateur radio use of the air waves is for personal satisfaction and for forwarding the "state of the art" of electronics and communication techniques. Amateur radio operations can be detected in designated bands throughout the radio spectrum, using a variety of modulation methods including Morse code, voice and digital modes, and image modes such as television and facsimile.
