In reply to GM0AXY:
The whole subject comes complete with several cans of worms!
We all like to use the correct call especially as we can then point out someone else has got it wrong. But in this case there do appear to be many contradictory or vague documents flying about.
In the UK case, OFCOM do seem to have problems with their own paperwork. The call printed has varied between M0FMF and MM0FMF on my licence despite not moving QTH! Currently it says MM0FMF and the last CEPT guidance I read said you sign /. Which means DL/MM0FMF rather than DL/M0FMF. The latter seems better to me because my call is M0FMF and is modified when I’m in some other bits of the UK. If I’m not in Scotland but Germany why am I expected to insert the Scottish modifier? Exactly!
From a SOTA point of view, the MT take the view that it is the intent which matters. So someone signing IK7/xxxxxxx instead of I/xxxxx is not a big problem. They had a CEPT licence and were trying to play by the rules. Just which rules is the problem! As long as the band/mode they operated on was common to both IK7 land and their home licence then the fact the prefix may or may not have been the right one is not an issue. You can argue they were operating illegally as they used the wrong prefix but that would really be splitting hairs.
There are some odd rules for CEPT which not everyone will be aware of. One is that in France to operate CW on HF you must have a CW test pass. People who gained an M0 call after WRC2003 and have no test pass cannot use CW on HF in France. Getting suitable paperwork is now a problem. As to whether this is enforced or not is unknown. It would be a wholly Kafka-esque experience to find someone like Tom signing as F/M1EYP/P on 20m CW operating (well) at 20+wpm and then be reprimanded and prosecuted for operating without a licence when he can’t get the test pass needed but would pass if the test was still taking place!
Likewise, operation in Malta 9H is OK for CEPT but you need to get a local call allocated. So 9H/MM0FMF/p is not on. But applying for the local call (I think FOC) and operating as 9H3xxxx is OK. Mike MM0ROV fell foul of this bizarre rule and being a complete gentleman deleted his log entries meaning he passed up points / uniques and association credits.
So it is intent that really matters. I doubt we will ask anyone to delete an activation entry because they erred on prefix in use. What we are concerned about are people who are deliberately cheating. Not being in the AZ, operation from a car etc.
