Also known as: RSGB, Radio Society of Great Britain
The Radio Society of Great Britain (RSGB) is the United Kingdom’s national society for amateur radio, founded in 1913 and one of the oldest such organisations in the world.1 It represents the interests of licensed radio amateurs to the UK regulator Ofcom, acts as the UK member of the international federation IARU, and supports the hobby through publications, training, contests, and technical services.2
Overview
The RSGB is a membership society: it is funded by and speaks for the UK’s radio amateurs, and it has no regulatory authority of its own. Its influence is exercised through advocacy and technical expertise. It is the recognised body that Ofcom consults on amateur licensing and band matters, and it coordinates UK band plans — the voluntary agreements that divide each amateur allocation into segments for CW, digital modes, SSB, and beacons — in step with the region-wide plans set through the IARU.
Beyond spectrum work, the RSGB runs much of the practical infrastructure of the hobby in Britain. It administers the examination syllabus and training path that lead to a UK amateur licence, publishes books and the monthly RadCom magazine, operates a national QSL bureau, organises contests and awards, and maintains an emergency-communications volunteer network. It is directly comparable to the American Radio Relay League (ARRL) in the United States — each is its country’s national society and IARU member — differing mainly in the national regulator it works with and the licensing system it supports.
Relevance to SDR
A large share of SDR hobbyists in the UK come to the field through amateur radio, and the RSGB is the organisation that maintains the band plans and licensing framework those users operate under. Its published UK band plans tell a listener which part of an amateur band to expect a given mode in — where CW gives way to digital modes or SSB — which is directly useful when tuning an SDR across the HF, VHF, and UHF amateur segments. The society’s training material is also a common on-ramp for people who then take up wideband receiving.
For a receiving tool like GopherTrunk, the RSGB is contextual rather than a decoded system. GopherTrunk concentrates on land-mobile trunking rather than amateur modes, but the same principle applies across the hobby: knowing the society’s band plan is the quickest way to predict what a signal in a given amateur segment is likely to be.
