The Radio Society of Great Britain and Ofcom have reached agreement on the optional use of special callsigns for two significant events during 2012.
For the Queen’s Diamond Jubilee, all UK amateur stations will have the option of applying for a variation to their licence if they wish, to use a special prefix for a five week period. This will add or substitute the letter “Q” in the place of the Regional identifier in the callsign. For the period of the Olympic Games and Paralympic Games, a similar facility will exist for a seven week period, using the letter “O”. Both the above facilities will also be available to Amateur Club licences, so expect to hear GQ4WAC and GO4WAC during this year!
