WWII wireless station at Stock

Last November Peter Turrall spoke on Marconi history to the Stock Heritage Society. During the ensuing question and answer session a member of the audience asked about a small wireless station which was set up during the 1939-1945 war on the outskirts of Stock village, at a farm which is now a private house named East View.

During tidying up work at the farm several bakelite pieces and ceramic insulators were found. The current owner of the property would like to know what sort of wireless station was there and also any details of the equipment. He remembers as a young boy seeing aerials erected in the farmyard, and although he has made enquiries in the village nobody has come up with any information.

Does any Veteran have any knowledge of this site? Please contact the editor who will pass on any information to the owner.

Following publication of this article we have received the following information from Professor Roy Simons

During the war I was in the same laboratory (Room 124) at Baddow where the Stock equipment was designed and monitored.

It was designed by Bill Agar a member of  T.L. Eckersley’s section

The equipment was used to measure the height of the ionosphere.

The following is an extract from a report on the work at Baddow by David Speake

“The team devised techniques of ionospheric sounding and developed measuring equipment the results from which were used to predict the performance of h.f radio channels.  Typical of the equipment built and put into service was a pulse transmitter feeding a wide-band rhombic aerial for vertical incidence ionospheric sounding. The equipment was installed at Stock (About six miles from the laboratories) on a site with the inappropriate name of Smallgains Lane!  It was controlled by telephone line from the laboratories and the delayed echoes received from the ionosphere were monitored round the clock by the RAF operators.  Data assembled from measurement of this sort was circulated to all three Services to guide system operators in selection of optimal frequencies for h.f. communication.’
