What is Radio Amateur?
Amateur radio is a popular technical hobby and volunteer public service that uses designated radio frequencies for non-commercial exchange of messages, wireless experimentation, self-training, and emergency communications.
Many amateurs begin with a fascination for radio communication and then combine other personal interests to make the pursuit of the hobby rewarding. Some of the focal areas amateurs pursue include radio contesting, radio propagation study, public service communication, technical experimentation, and computer networking. More than two million people throughout the world are regularly involved with amateur radio.
All amateur radio operators are required to display knowledge and understanding of key concepts of electronics, radio equipment, antennas, radio propagation, RF safety, and the radio regulations of the government granting the license. This usually takes the form of an examination.
Amateur radio operators use various modes of transmission to communicate. The most common modes for voice transmissions are frequency modulation (FM) and single sideband (SSB). Morse code, or CW from "continuous wave" was developed by Samuel Morse and dates to the earliest days of radio. Many amateur radio operators still enjoy using the CW mode.
An amateur radio operator uses a call sign on the air to legally identify the operator or station. Here in South Africa this usually starts with the prefix ZS, ZR or ZU.
Many people start their involvement in amateur radio by finding a local club. Clubs often provide information about licensing, local operating practices, and technical advice. KARTS offers such classes. Please contact any committee member for information.
