Ham radio, also known as amateur radio, is a popular hobby that allows individuals to communicate with others using radio frequencies. Enthusiasts, known as ham operators, use various equipment to send voice, text, and even images over long distances without relying on the internet or phone networks. This form of communication can be used for personal enjoyment, emergency situations, and community service. To participate in ham radio, operators must obtain a license from their country's regulatory body, which ensures they understand the rules and technical aspects of radio operation. The hobby fosters a sense of community, as operators often connect with others worldwide, sharing knowledge and experiences.
