With the 'London 2012 Olympics' official opening taking place the 'Amateur Radio Flagship Event Stations' will be operating beginning Wednesday 25 July 2012 until the Games close on 9th September 2012.
The London station 2O12L (two-oscar-one-two-London) and the station in Wales (two-oscar-one-two-Wales) will be operating on amateur HF and VHF/UHF bands during the event.
The Barry Amateur Radio Society in Wales, subject to operator availability and suitable passes, will endeavor to make contacts via the amateur radio satellites as well, of course, as the HF bands.
London has a restriction imposed on VHF/UHF activation which will limit personal operations on the satellites. Outside the restricted zone however there maybe other amateur radio operators who may be active, not as "flagship stations" but using a personal or club call sign under a notice of variation.
