Radio amateurs, also known as ham radio operators, are individuals who engage in two-way radio communications for personal interest, recreation, or non-commercial purposes. They use a wide range of frequencies, from low-frequency (LF) to extremely high-frequency (EHF), and employ various modes such as voice, Morse code, and digital data transmission. Radio amateurs are licensed by national regulatory authorities, which allocate specific frequency bands for their use. These bands are designated for experimental and non-commercial communications, and operators must adhere to strict rules and regulations to prevent interference with other services.

The primary goal of radio amateurs is to enhance their technical skills and knowledge of radio communications. They participate in various activities, including local and international contests, emergency communications, and technical experiments. Radio amateurs also play a crucial role in disaster relief and public service communications, providing reliable communication links during emergencies when other systems may fail. Additionally, they contribute to the development of new technologies and standards in the field of radio communications.

Radio amateurs are organized into clubs and associations, which provide training, support, and opportunities for social interaction. They often collaborate with other hobbyists and professionals to advance the field of radio communications and promote its benefits to the public. The International Amateur Radio Union (IARU) represents radio amateurs worldwide and works to coordinate international regulations and standards. Radio amateurs are a diverse and passionate community, united by their shared interest in radio communications and their commitment to continuous learning and improvement.
