(Note: The Amateur Radio Service has no relationship with the Citizen's Radio Service or CB. Amateur Radio operators must pass one or more written examinations covering regulations, electrical theory and concepts, antenna and radio signal propagation, RF safety and other topics. Licensed Amateurs are legally permitted to transmit at high power (depending on the country, up to 1,000 watts or more), and on a variety of radio frequencies from long wave through microwaves. Amateurs conduct communications using wide variety of technologies to provide, voice, data and even television and satellite communications. Volunteer amateurs have constructed and orbited dozens of satellites over more than a 35 year period. Currently, over 20 Amateur spacecraft are in operation and in use by licensed Amateur Radio operators.)
