Ham Radio
Ham radio, also known as amateur radio, is a hobby and service that involves the use of designated radio frequency bands for non-commercial communication, radio experimentation, and public service activities. Dating back to the late 19th century, ham radio operators, or “hams,” use a variety of radio equipment to communicate with each other locally, regionally, and globally. Ham radio enthusiasts engage in a wide range of activities, including voice communication (using single sideband, FM modulation, or AM modulation), Morse code communication, digital communication modes (such as PSK31 and FT8), satellite communication, and experimentation with antennas and radio equipment. Ham radio operators are amateur licensed by their respective national telecommunications authorities and must adhere to regulations and operating procedures to ensure proper and ethical use of the radio spectrum. Ham radio serves as a valuable resource for emergency communication during disasters, public service events, and community service activities, providing a means of communication when other forms of communication are unavailable or unreliable. Ham radio also fosters international goodwill and cultural exchange, as operators communicate with fellow enthusiasts from around the world. s://en.wikipedia.org/wiki/Amateur_radio
