You need an easy-to-earn license to transmit on an amateur radio frequency. License tests cover electronics theory and amateur radio rules and regulations. Study guides are readily available. There is no age restriction. Each country has its own licensing arrangements. Many countries share many of the same frequency bands with hams in the United States. Each license class allows operation in certain bands, using certain modes. The higher the class of license, the more allowable frequency bands that are available for use.
The American Radio Relay League (ARRL) helps many get into amateur radio. The ARRL was organized in 1914 by H.P. Maxim to help relay radio messages. Most radio messages had a 25-mile range at that time and were transmitted around 1.5 MHz, at the high end of the AM broadcast band. Now, local volunteers around the country administer amateur radio tests. These volunteers are usually members of an amateur radio club.
