Abstract :
On Sunday 17 October, members of the Chelmsford Amateur Radio Society transmitted from the Marconi Hut at Sandford Mill Museum using a special event call-sign to celebrate the hundredth anniversary of the first advertised airborne wireless and the first air-sea rescue involving wireless. Other amateur stations around the word were expected to take part, including the Marconi Radio Club of America, W1AA. They were commemorating a series of events that began in 1906 when 52 year old American writer and explorer Walter Wellman purchased a non-rigid dirigible airship from Mutin Godard in France with the intention of becoming the first person to reach the North Pole by air.
