International Marconi Day - 2014 at Sandford Mill

14th July 2014 Created this page.


Marconi's Birthday was on the 25th April 1874 & the Cornish Radio Amateur Club, (CRAC) GB4IMD normally arrange International Marconi Day as the nearest Saturday to his birthday so this year it was the 21st April.

CARS as a Society operate as a "team" - the Aerial Erection Team tested the 80 Metre Aerial over the water for the SSB Aerial while Tony, G4YTG built, erected and tested a 14MHz Dipole over Dr Bowles's Office for use by the CW team.

"Friends of the Museum" organised Car Parking, Teas and provided Members to Staff many of the exhibits in the building. At 9.30am BST when the first members of the Public turned up, everthing was just getting going for formal opening at 10.00.

CARS Special Call-Sign GB100MWT allocated by Ofcom for the year was used to remind the World that all equipment used in the rescue of the 705 persons was designed and manufactured in Chelmsford.
One must not also forget the large number of Marconi trained Wireless Operators involved directly and indirectly on English, French and German ships as well as the shore stations at Cape Ray, Cape Race and New York.

Colin, G0TRM had his famous Morse tape transmission equipment in use which some of it is 100 years old.     Youngsters love typing their message and seeing it printed out - they are often given a Certificate.

Sandford Mill was open to the public FREE OF CHARGE from 10am to 5pm with lots to see and for children to play with.

The new book written by Tim Wander, G6GUX "Marconi's New Street Works, 1912 - 2012" was on sale.   A number of CARS Members and Marconi Veterans feature in it.

Tim lectured in the Barn all day to the delight of the many persons who jammed the room to listen to him.

A very good day - Thank you Dr Bowles for allowing CARS to operate from the site.
