Badge of the International Amateur Radio Union

Amateur radio is a service available in nearly all countries, allowing individuals to operate two-way radios and engage in communications as a hobby. A license is required and is obtained by passing a test demonstrating adequate knowledge of Rules and Regulations, Operation of Equipment, Propagation, and more. There are typically multiple license classes, with each one up granting more privileges and having a more difficult test. Many different modes and bands are used. It is internationally represented and coordinated by the International Amateur Radio Union and each country has its own organization (such as the American Radio Relay League in the USA). Amateur radio has secondary allocation in some bands.
