Been there, done it, got the T-shirt. I’ve had 2x Scottish Homecoming prefixes, ‘A’, an Olympic ‘O’, a Queen’s Jubilee ‘Q’ (or was it ‘R’?) I’m sure I had an ‘E’ once. And I must admit that I now get bored with them fairly quickly. I think I have had at least once QSO with each one. I did use the A prefix for a while in 2009? but realised that MIKE ALPHA ZERO takes longer to say than MIKE MIKE ZERO. Anything that makes a long callsign longer is not a good thing!
You’ll get bored Karl. You’ll forget and use it when you’re out of Cornwall and some wag will helpfully correct you. Or worse because of your current licence type, give you a hard time. I’ll give it a few months and use will drop to just a few die-hards.
The best special prefix, however, was when there was some big in event in Wales. All stations in Wales (irrespective of their home QTH) could change their MW/GW/2W1/2W0 prefix to 2C for a month. In those days, Novice licensees could not use 2m. Myself and Brian G4ZRP had been doing some checks from Cyrn-y-Brain summit for a contest. When we were finished we called CQ on 2m with a handy as 2C4ZRP/P. The number of experts who came and told us “novices are not allowed on 2m” was impressive. Boy did they get upset when they were told 2C4ZRP/P was a full licence.
Only if your elected reps in local government and or Westminster can pull the right strings with their chums in OFCOM, Walt. !
