What is Amateur Radio?

Amateur radio, also known as ham radio, is the use of radiofrequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private, recreation, radiosport, contesting, and emergency communication. The term “amateur” is used to specify “a duly authorized person interested in radioelectric practice with a purely personal aim and without pecuniary interest;” (either direct monetary or other similar rewards) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.)
