On July 21st, His Royal Highness Prince Philippe will become the new king of Belgium and His Royal Highness King Albert II has reigned for 20 years. For both occasions, all radio amateurs with a Belgian license will be allowed to use the prefix "OO" instead of "ON" from July 21st until and including September 20th, 2013. Belgian vanity callsigns (with only one letter in the suffix) may not change their prefix. Some vanity callsigns already have an "OO" prefix.
The Belgian IARU Society UBA is issuing a commemorative award for working a specific number of these OO stations. Details are as following:
| Stations located in | Number of different OO stations needed | Minimum different OO prefixes |
|---|---|---|
| Belgium | 25 | 5 |
| Europe, except Belgium | 15 | 3 |
| Outside Europe | 7 | 2 |
Please note that only OO stations with at 2 or 3 letters in their suffix count towards this award. Each OO stations can only be counted once regardless of the band/mode used.
The award will be issued in electronic (PDF) version. No fee required. Log extracts should be mailed before the end of 2013 to the UBA.
UBA Award Manager Egbert Hertsen ON4CAS. SWL stations may apply while indicating the callsign the OO stations had QSO with.
