In this DVD, Dr Bill Penley, CB, CBE, one of our most distinguished engineers and a veteran of Worth Matravers, and Dr Phil Judkins, a radar historian, describe in non-technical language the top secret wartime work done at Worth. The DVD starts with the background of how TRE (the Telecommunications Research Establishment) came to Worth in the first place, and the reasons for its eventual sudden demise with most of the top scientists being ordered out to a safer place "before the next full moon".

This is a fascinating story brought to life by rare original pictures from 70 years ago, together with exciting works of art, and visits to all the radar sites in the Purbeck area of South Dorset including St Aldhelm's Head, Leeson House, Brandy Bay, Tilly Whim and Durlston, Acton, Peveril Point, and many more.

Cameraman, Editor and Director for Echoes of the Past, John Hale, whose idea for making the DVD was conceived after hearing one of Dr Bill Penley's talks, has had a lifetime of working on a wide variety of television programmes, mostly for the BBC in London.  He has had three BAFTA nominations and has, since retirement to Dorset in 2001, made other notable DVDs locally including The Traditional Crafts of Dorset and Lawrence of Arabia - His Final Years in Dorset.  Greenacre AV Productions www.greenacre.info .

This booklet tells the story of early radar development in the UK from the Daventry experiment in 1935 to after the D-Day invasion.  It focuses on the period from May 1940 - May 1942 when radar development was centred at the Telecommunications Research Establishment (TRE) in Purbeck, Dorset.  Both of the authors worked at TRE during that period, and the most significant developments were probably made then.  The booklet was originally compiled to accompany the Purbeck Radar Museum Trust's 1994 D-Day anniversary exhibition at Swanage Town Hall.

This booklet continues the radar story started in "Dorset's Radar Days" to the end of World War II and beyond (including a short resumé of the story before that).  After D-Day mobile radar units were designed by TRE and deployed in Europe and the Middle East.  Following the war, the technological advancements spawned by radar and the Enigma code breaking at Bletchley Park went on to form the basis of the electronics industry we take for granted today: Air Traffic Control, blind landing aids, radio astronomy, terrestrial and satellite communications,... and microwave ovens!!  Crystal diodes used in centimetric radar receivers were a step on the path to the development of the transistor and, Geoffrey Dummer, instigator of the radar Plan Position Indicator, went on to pioneer integrated circuits with multiple transistors on a single semiconductor chip.

This brochure gives a brief but insightful outline of early radar development in the UK.  What started as one scientist's concern about air defence, ended up being key to the success of the UK and its allies in World War II.  There is a fold out map showing the radar development sites in Purbeck, Dorset from May 1940 - May 1942 with a narrative which summarises key activities at that time.  The brochure also includes photographs giving a snapshot of the radar sites and masts.  While only one building still stands today, the story and technological advances live on...
