UK Amateur Radio Call Signs
Amateur radio or ham radio call signs are unique identifiers for the 60,000 licensed operators in the United Kingdom. Call signs are regulated internationally by the ITU as well as nationally in the UK by ‘The Office of Communication’, known as Ofcom. It regulates amateur radio in the country as an independent regulator and competition authority for the UK communications industries, with responsibilities across television, radio, telecommunications and wireless communications services. It assigns call signs, issues amateur radio licences, allots frequency spectrum, and monitors the radio waves. Ofcom is no longer responsible for setting and conducting amateur radio exams, which are now run by the Radio Society of Great Britain on their behalf. The Radio Society of Great Britain (RSGB) is the United Kingdom’s recognised national society for amateur radio operators. The society’s patron is Prince Philip, Duke of Edinburgh, and it represents the interests of the UK’s licensed radio amateurs.
