An Amateur Radio Operator, often called a "ham," is a person who uses radio equipment to communicate with others for non-commercial purposes. They are licensed by government authorities and operate on designated radio frequencies. Hams often engage in activities like emergency communication, public service, and experimentation with radio technology. To become an Amateur Radio Operator, individuals must pass an exam that tests their knowledge of radio theory, regulations, and operating practices. This hobby fosters a sense of community, as operators often connect with others worldwide, participate in contests, and share their experiences through local clubs and organizations.
