He was actually operating from EU-097 and give that reference frequently but as the callsign area number wasn't included in the prefix the option to log it under the IOTA window didn't occur.
...and correct me if I'm wrong, but it isn't compulsory for a visiting Amateur operating under CEPT to include an area number in the prefix and some regulatory bodies advise against doing so.
Edit; Here's the correct format of a callsign if operating in Iceland.
(C): Licensees from these countries should only use the TF prefix in front of their call signs, but not the TF prefix with an Icelandic call area number. For example: TF/W1XXX would thus be correct; but TF6/W1XXX incorrect.
Would a solution not be to log all OH/ prefixes as the primary and the lesser activated one OH0/ as the exception....is that possible?TF is not a problem because it only resolves to one country, Iceland.
Take VK for example. Without a number AND at least the first letter of the suffix, it could be one of many countries, Lord Howe, Christmas, Is., etc.
While it well may be that the number is not required under CEPT, how does the logging program know which too choose from? It's impossible unless it is contained in an external source that the program uses or the user selects the correct country.
We have a logging program, not a mind reader
Edit;...and I've just checked and that appears to be the recommended way of operating there.
"The call sign shall be OH/ in front of the amateur's national call sign. E.g. OH/DL1XXX/P. When operating in the Province of Aland, the call sign shall be OH0/national call sign."
