On 3rd August 2014 the first day that the licence GB100ZZ was available – the station was et up and tested. David G3PLE making over 80 contacts using both SSB and CW.  On the 4th August television crew from BBC Spotlight arrived, followed by the local reporters and photographers, David gave a short explanation and background to the events of 100 years ago.

On the 6th/7th August the secretary of the ROARS Geoff Valentine G0UVX was on duty during the day light hours on CW.

During the month the station was delighted to welcome guest operators who visited whilst on holiday, these included Paul G1BZM, Neil G0HJC and Dom M1KTA.

When the doublet aerial became available on the WARC bands this proved invaluable with a pile up of Japanese stations wanting the call sign. 70 DXCC countries including Samoa, Taiwan,China,Hong Kong, Sumatra to name a but a few were in the log. In all a total over 3300 QSO’s were achieved in the August time frame.
