Announcing the activation of the Special Event station VI4SEA.

This commemorative call sign, VI4SEA, is in honour of the Officers and Sailors of the Light Cruisers, H.M.A.S. SYDNEY, and S.M.S EMDEN who gallantly fought in the first ever naval action of the Royal Australian Navy, on November 9th 1914, off the coast of the Cocos Keeling Islands in the Indian Ocean.

VI4SEA will hit the airwaves on November 1st 2016, and continue through to November 9th.  Our operations will see us transmitting between the 630m band through to the 6m band.  Our team of Amateur Radio Operators are a combination of ex naval, military and professional individuals.

We do not seek to glorify War in any form, but rather to commemorate the deeds of brave men at sea in a time of war.  A special webpage has been set up on qrz.com under VI4SEA.

We, the VI4SEA Team look forward to working you one and all, as we pause to remember these brave sailors from Australia, Britain and Germany who fought in a devastating naval action on the high seas that November day back in 1914.
