amatöörraadiot

Amatöörraadio, often referred to as ham radio, is a hobby and public service that brings people, electronics, and communication together. Amateur radio operators (hams) use their knowledge and equipment to communicate with other radio amateurs around the world. This communication can be done via voice, Morse code, digital modes, and even through satellites.

The hobby is governed by regulations in most countries, requiring operators to obtain a license. Licensing typically involves passing an exam that tests knowledge of radio theory, operating procedures, and regulations. Licenses are often tiered, with higher-level licenses granting access to more frequencies and operating privileges.

Amateur radio is used for a variety of purposes. Many hams enjoy the technical challenge of building and operating their own equipment. Others are drawn to the social aspect of connecting with people globally. A significant role of amateur radio is in public service. During emergencies or natural disasters, when normal communication infrastructure may be down, licensed amateur radio operators often provide vital communication links for emergency responders and affected communities. This capability is recognized by governments worldwide.

The frequencies used by amateur radio operators are allocated by international agreement and are distinct from those used for commercial or broadcast purposes. These bands vary depending on the license class and geographical region. Amateur radio offers a unique blend of technical skill, global connection, and community service.
