GPO Radio Laboratory – Backwell – Then and Now April 2017

Some of the pictures of the early site were taken by me.

Pretty dure you worked with my dad, cliff scrase

 

[Iainiain]

I was there from 72 to 75. We may have known some of the same people.

Cliff scrase, john davis, wally,

 

[Iainiain]

you will have to tell me his name.. or maybe where he worked there? In a lab, the workshop? or maybe he did special investigations to telephone faults?

His names cliff scrase, also john davis, wally etc. I remember most of them too. Camping etc

 

[Roger Wood]

Wally? Was he the cook?

 

[Iainiain]

Wally? Was he the cook?

No worked in the labs too

Hi Roger, did you work at Backwell? these recent posts have been brought to my attention as we are trying to get the information accepted by BT Archives and it would be nice to know where they came from and are there more, exciting times.

Yes his names cliff scrase. Worked in the labs. With wally, john knight and others

Would that include the Hiroshima bench incident?

In 1939, with the outbreak of war, some staff were moved from the Post Office research laboratories at Dollis Hill, London to a small laboratory at Backwell Hill, Somerset and another at Rugby.

At Backwell they attempted to foil the German air raids over Bristol. Their roles included beam bending. This involved projecting beams around Bristol to provide intersections to the German beams in the surrounding countryside. Fuel dumps were placed where these beams intersected and when the incendiary bombs were dropped the theory was that these dumps would catch fire, and the heavy bombs would be dropped on the ensuing fire away from the city.

On one occasion a member of the staff was sent to research German radio transmissions. They posed as a crew member on a cement barge travelling between England and the Netherlands. They got caught in a storm, the hatch to the hold was destroyed and water entered the cement hold. The barge was wrecked on the Scottish Coast, but everyone managed to survive.

After the War the staff at the Backwell Hill Radio Research Station were employed on communications research.

This included measuring the noise from clouds using a dish located on Bodmin Moor. They then worked on ways of filtering out this noise

This research helped pave the way for satellite communications.

The staff at Backwell Hill were then heavily involved in the first transatlantic TV broadcast from Goonhilly Down to America in the 1960s (Telstar). Their role was to design and build the equipment and dish to test Arthur, the first dish at Goonhilly. When the first TV transmission happened on the 23 July 1962 staff from Backwell Hill were operating Arthur. They had to manually align the dish with the point that the Telstar came over the horizon and then using gears (no computers) follow it for 20 minutes until it disappeared over the other horizon.

The Radio Research Station at Backwell Hill was closed in the early 1970s and the staff transferred to Martlesham Heath, Suffolk where they were involved in projects that included research into suitable wavelengths for mobile phone communications.

hi I worked at Backwell research labs since 1955 up to its close when staff went to Martlesham. The late Ted Jervis was my boss for some time, as was Sid Pitham who became OC at Goonhilly.
Most of the pictures of Backwell site are mine.
A small group who have got together the history of the Research Labs Backwell are trying to get them recorded but BT so far do not respond.
Most of the technical history written I believe to be incorrect.
I knew Roger Wood who joined from university and Mr Wilson , Peter Mountain, Mac, RV Hinchliffe .
John Knight Lab 1, and 2, and 3, and 4 when it became a repair centre under Bristol Region.

We must have worked together then. I think I have some memorabilia somewhere. Probably just notes about the stuff we used to work on. I'll see if I can dig it out.

 

[Roger Wood]

I found this list of the folks at Backwell in 1975, when the research group was moved to Martlesham. Seeing the names brings back some of the faces and memories - good times!

It's great to see some flesh put on the bones and I love seeing the social history of these sites. The Backwell site is probably still there decaying now, five years ago the mains power was on to some parts. Ouch!
Is your research group in contact with or part of the THG? They might be able to help. I'm a member.
I might have more photos if it helps your project, and hope it goes well.

No, I didn’t keep up with any of those folks. It would be fascinating to find out what happened and where they all ended up. I’m in California now - been here since 1979.

Hello Cliff, I see there are lots of pictures of PO RADIO LABS BACKWELL on the site, many of which I took. Most of the information about the work done there is wrong as I am sure you now know.
Keep smiling
Theres not many of us left.

First Bit:
This is not a proper report, but it feels like too much for the ‘Before-and-After’ section. These are archive photos dug up during the researching that have never been on Google images before, so It seems only fair that the world should now ogle them and my pathetic attempt at aligning some then-and-now photos.

Exploring this ‘lovely hillside’:
I’ll admit that I am a nutter for anything technical, particularly stuff that is well built.
Following the DP Bristol 2017 meet DeadFormat and I headed over to study what remains of Backwell.
Why? You might ask – after all there is almost nothing left to look at. (If you can answer that question for me then please let me know what the answer is.) Backwell is currently awaiting planning permission for four luxury homes to be stuck on a lovely hillside, so it might be a case of now-or-never. Plus! Her Majesty’s Government paid for it, so I will be enjoying it.
DeadFormat has written about this stroll in a charming humorous tone. I suggest you try his report if you want to read a delightfully British and more interesting writeup. I however enjoy researching and writing about such outposts of technology.

GPO Radio Laboratory – Backwell – Then and April 2017
Backwell PO Radio Laboratory first came about around 1937. Some of its earliest work was to develop air conditioning for telephone exchanges.

Nowadays:

The earliest photos show VHF Television signals being transmitted to Castleton (another laboratory in Monmouthshire) by 1945. The station was actually further down the hillside.
View attachment 219011
By 1958 the new site further up the hill was working in conjunction with a station in Slough for Tropospheric tests (effectively transmitting Satellite TV, but avoiding clouds), note the dishes:
View attachment 219012
The final experiment was for 120MBPS Data links with Castleton again, note the new mast:

This unassuming shed [red arrow] is the only surviving building from the earliest radio station:

It is still in its original location, seen here as the closest building to the camera on the RHS:

This hut was used for the 1950s experiments in the first “compound”:

It was always intended to be a lesser published (but not really top secret) operation. Despite this, 24 hour Security was provided from the 'White House' - the curved front building, and an on-site fire station (upper LHS) was added.
New buildings were under construction but reportedly never finished at the time of closure, they can be seen at the top RHS of the driveway
View attachment 219020
Not much is recorded about the technologies developed onsite, but some archives and equipment have been taken into the National Collection BT Archives at Holborn Telephone Exchange.

The site became redundant after 1975 but was still in use for some sort of British Telecom work in the early 1980s.

Along with the site sewage and water treatment works, it was sold in 1993 to a BT Manager. This is what it looked like then. His executors of will are currently applying to build four houses on the site.

Well now. That is a photographic potted history of the place that made your TV, Skybox and even mobile internet possible.

Cheers everyone. Regards, Electric.
