Since 2006 the UBA is activating it's headquarter call sign OP0HQ during the IARU Contest 2009 on second full weekend of July, in a well concerted HQ-effort. Also this year we have put together a competitive team to man 12 band-mode slots aiming to give you the ‘UBA’ multiplier on all 6 bands and both modes. We will be using the call OP0HQ, which is still a very rare prefix. So, prefix hunters, watch out for us!

All QSO's will be confirmed with a QSL via the bureau. If you really need a direct QSL, you can send it to ON7LX (UBA HF Manager). The address is OK on QRZ.com.

We will try to work you on all bands, both modes, and hope you will be there to call us! The list of participating stations and operators will be published later.
