BBC News reports that hams in Great Britain can apply for special call signs to commemorate the royal wedding scheduled for this coming weekend:
The telecoms regulator Ofcom has agreed to issue temporary licences, meaning the UK’s 60,000 amateur radio enthusiasts can change their call signs to mark the royal wedding. The use of the letter “R” in a UK call sign will signify that the operator is celebrating the event.
The FCC should do something like this to commemorate special events here in the U.S. It doesn’t seem to me that it would be all that difficult or expensive to add something to the FCC website that would allow currently-licensed hams to apply for the commemorative callsigns.
