It has no statutory standing and you don't have to join. You need a Licence from Comreg. You need to know the Comreg Regulations Note that dBW is a log comparative scale to 1 Watt. Thus 0dBW is 1W and 26dBW is 400W. Recent changes in the last few years: [table !Band in MHz| Notes
0.1357...0.1378 | No SSB, 1W ERP = 0dBW ERP (needs about 2kW PA on a 20m wire aerial)
0.5 | Test Licence via IRTS
7.1...7.2 | Added to 40m 7.0...7.1 MHz band.
5.00...5.50 | Special Permit needed. Channelised Operation, no transmission to UK Cadet stations
1,300...1,304 | added for repeaters to 1.2GHz band
2,300...2,450 | recent changes Overlaps WiFi and Video Senders
5,650...5,850 | May overlap some WAN and WiFi
10,000...10,500| Gap at 10.270...10.300GHz. Overlaps Broadband downlinks (up to 10.270) and Traffic sensors at 10.4GHz. Many Beacons at 10.252GHz ]
Major Changes applied in May 2009 when "Wireless Experimenter" was replaced by "Radio Amateur". However anyone can apply for a "Test" Licence to do experiments on any band, power and modulation. Only reasonable requests are approved. I've used a Test Licence commercially in UHF TV band to test Broadband gear.
