In the course of the Second World Struggle, there have been an estimated 250 alerts intelligence (Sigint) websites throughout the UK from as far south as Cornwall to as far north because the Orkneys.
Many vital websites at the moment are in peril of disappearing, both being demolished for housing or just being left to decay, and their significance is being misplaced to historical past.
Dave Abrutat, the official historian at GCHQ, is on a mission to protect this historical past earlier than it’s misplaced and the folks recollections are forgotten.
Bletchley Park, the house of wartime codebreaking, is likely one of the greatest preserved and most well-known websites, nevertheless it represents solely seven years of GCHQ’s historical past.
Abrutat estimates that because the First World Struggle, tens of 1000’s of individuals have labored in alerts intelligence and communications safety in organisations as numerous because the Publish Workplace, the Admiralty, the Royal Indicators and the International Workplace, and US Airforce websites similar to Chicksands in Bedfordshire, identified for its “elephant cage” radio receiver (pictured above).
“You understand, it’s an enormous story, and it’s the richest story on the earth, and we’ve got bought to take care of it,” Abrutat tells Laptop Weekly.
Preserving alerts intelligence and safety
Abrutat is the driving pressure behind a charity that goals to protect the UK’s alerts intelligence and communications safety historical past.
The Nationwide Indicators Intelligence and Safety Belief (NSIST) will fill a spot by serving to to report and protect archives, folks recollections and historic websites that fall outdoors the remit of present our bodies.
Chicksands Priory was used as ‘Y’ station throughout the Second World Struggle and later grew to become the location of the US Airforce interception station focused on the Soviet Union, referred to as the ‘elephant cage’, throughout the chilly conflict. Supply: GCHQ
Though GCHQ has a division of 4 folks working in its historic archives, it doesn’t have the funding or assets to protect or handle the nation’s alerts intelligence and communications safety historical past.
Abrutat has pulled collectively what he calls a “coalition” of volunteers to run the charity, and hopes to draw sponsorship from companies and grant-awarding our bodies.
People who find themselves can signal as much as the NSIST web site for £10 a yr to obtain newsletters and entry articles and uncommon pictures in regards to the historical past of the UK’s communications and alerts intelligence operations.
The charity’s remit covers greater than the preservation of historic radio interception websites. The historical past of communications safety, cyber safety, and even the millennium bug that threatened to carry the world’s computer systems to a halt in 2000, function in its newsletters.
“I’m primarily doing all that in my spare time, so I’m working seven days per week,” he says. “How sustainable that’s, I don’t know, however I’m pushed by the eagerness and enthusiasm I’ve for heritage.”
I’m doing all [the NSIST charity work] in my spare time, so I’m working seven days per week. How sustainable that’s, I don’t know, however I’m pushed by the eagerness and enthusiasm I’ve for heritage Dave AbrutatGCHQ historian
Abrutat is the writer of two books on the historical past of alerts intelligence. His first, Vanguard, revealed the little-known alerts intelligence and reconnaissance operations that made the D-Day landings attainable.
His second guide, Radio Struggle, tells the story of the key military of volunteer radio operators – the Radio Safety Service – that monitored German intelligence alerts visitors throughout the Second World Struggle.
Piecing collectively this secret historical past includes painstaking detective work, gathering data from private and non-private archives and newspaper libraries, and speaking to individuals who have labored within the providers.
Abrutat has discovered that vital alerts intelligence materials that ought to be within the Nationwide Archives, usually, inexplicably, has not been preserved.
“Typically there may be nothing. It’s most likely simply been destroyed, and that historical past is gone,” he says. “It’s mind-boggling that we might do this.”
Sandybed Lane
Abrutat grew up within the north-east coastal city of Scarborough. The city, now the house of a GCHQ outpost, lays declare to being the longest frequently serving alerts intelligence web site on the earth.
Scarborough’s unique wi-fi telegraphy station was arrange on Sandybed Lane by the Admiralty in 1912. In the course of the First World Struggle, radio operators intercepted German naval messages, which have been then despatched to the Admiralty for decoding.

The station’s route finders have been in a position to find German ships by triangulating their place from radio transmissions. In the course of the Second World Struggle, Sandybed Lane tracked German battleship Bismark, enabling it to be destroyed by an RAF aircraft.
Abrutat had no thought in regards to the historical past of Sandybed Lane when he was rising up within the space.
“The truth that some of the vital [signals intelligence] websites was simply actually across the nook from the place I used to stay sparked my curiosity,” he says. “It’s disappeared from the consciousness of the neighborhood, and it’s a web site that the city ought to be very happy with.”
When he started researching Sandybed Lane, Abrutat discovered there was little or no data in GCHQ, the Admiralty and different authorities archives.
An opportunity encounter with a volunteer at a library led him to seek out descriptions of the location and images of its employees in native newspaper archives.
Bob, the station mascot at Sandybed Lane, was awarded an ‘iron cross’ by station employees after operating away underneath hearth from a German ship
The station’s mascot was a canine known as Bob, who was mentioned to be expert at climbing ladders and sending Morse code, Abrutat found. Bob ran away when the city was attacked by a gunboat in 1914, and as a joke acquired an ‘iron cross’ for bravery from station employees.
“One of many causes we need to create this charity is to instil inside native communities the sense of neighborhood satisfaction in what occurs at these websites, a few of which have lengthy since gone, a few of which there are archaeological stays, a few of which nonetheless exist,” he says.
Disappearing historical past
A lot of the particular gear developed for alerts intelligence and safe communications now not survives. The Colossus machines – the primary semi-programmable digital computer systems that have been constructed at Bletchley Park to interrupt the German Lorenz code – have been destroyed after the conflict to protect their secrecy.
Different gear has merely change into out of date over time, thrown away or recycled for spare elements. It’s uncommon to seek out gear tucked away in a cabinet that might be given to a museum, says Abrutat.
“I frequently discover media in our archives – for instance, reel-to-reel tapes – however we haven’t bought the package to take heed to them after issues have been thrown away a long time in the past,” he says.
Beaumanor Corridor
NSIST additionally has plans for one of many best-preserved websites outdoors Bletchley Park. Beaumanor Corridor in Leicestershire, a wi-fi interception or Y station, performed a significant function in gathering radio intelligence throughout the Second World Struggle.

Greater than 1,500 folks labored there. Intercept personnel stationed in buildings disguised as cottages, barns and stables transcribed encrypted German and Italian messages. The intercepts have been recorded by hand and despatched by bike courier to the Bletchley Park codebreaking centre.
The charity plans to work with Leicestershire County Council to protect the buildings on the web site and to take away asbestos from the roof of the principle operations constructing in order that it may be opened to guests.
There are additionally plans to fund an archaeological dig. On the finish of the conflict, in line with native lore, the conflict workplace dumped alerts gear in underground icehouses on the property and buried it. Lately, a World Struggle Two bike was discovered on the location.
“There’s by no means been any archaeology performed,” says Abrutat. “There might be [radio] receivers, direction-finding gear … we don’t know.”
Whaddon Village
For Abrutat, some of the vital historic Sigint websites, and maybe one of many least identified, is in a small village in Cambridgeshire.
Though Whaddon is a tiny settlement, it grew to become some of the vital hubs for alerts visitors for Britain and its allies throughout the Second World Struggle.
From there, a transmitter at Windy Ridge acquired “extremely” intelligence despatched over a teleprinter wire from close by Bletchley Park and disseminated it over the airwaves to commanders within the area.
The Secret Intelligence Service, MI6, operated from the grounds of Whaddon Corridor, offering radio communications providers to British embassies and brokers of the Particular Operations Government working in occupied Europe.
Codebreakers at Bletchley Park
Uncommon wartime footage of MI6 officers working at Whaddon Corridor and the solely identified footage linked to the codebreaking operations at Bletchley Park have been found in 2020 and supply a novel historic report of the individuals who labored there.
“This was some of the vital websites, not simply on a nationwide degree however at a world degree. It’s a small village, nevertheless it grew to become one of many hubs for Bletchley Park and British and allied Sigint throughout the Second World Struggle,” says Abrutat.
By working with the Parish council, native landowners, army and archaeological societies, NSIST has plans for an archaeological survey of 4 websites across the village.
There are additionally plans to run cyber safety outreach programmes that would mix coaching in cyber safety with excursions of historic websites.
“You then educate the subsequent technology, so you retain the flame burning in the local people about what went on of their city,” he says.
Nationwide assortment
Certainly one of Abrutat’s goals is to construct a nationwide heritage assortment that may preserve and protect historic data of alerts intelligence and communications safety, each labeled and unclassified.
GCHQ’s small workforce of historians fulfils that function as greatest it could, however the organisation doesn’t have the assets or the cash to make conservation a predominant precedence.
“We nearly have to divorce GCHQ out of it and doubtlessly use the charity to get in correct conservation specialists to handle the gathering,” he says.
The GCHQ historian says one of many issues he has discovered by means of his analysis is that there are deposits of archival materials “all over”.
Abrutat’s guide on the Radio Safety Service took years of labor as he pieced materials collectively from a number of sources.
“If you wish to attempt to pull a story collectively about simply that one single story, you need to go in all places, all throughout the nation. Some are in non-public archives, some within the Nationwide Archives, some in GCHQ,” he says.
Though a curated nationwide assortment is a few years away, Abrutat is optimistic he can safe the grants and sponsorship to make it occur.
Spy museum
Patricia Moon
Patricia Moon, a world know-how gross sales strategist who has volunteered as a trustee of NSIST, developed an curiosity in know-how at a younger age.
Introduced up on Langley Airforce Base in Virginia, lots of her associates, kin and neighbours labored for the army or have been members of the intelligence neighborhood.
She says NSIST is about greater than preserving historic websites, it’s about preserving the tales of people that labored in intelligence and safety, and preserving their experience for future generations.
She want to see NSIST play a job in growing a spy museum within the UK, maybe modelled on the Worldwide Spy Museum in Washington DC.
“It might be a scientific house for youthful generations enthusiastic about know-how, for the neighborhood at giant and for future generations to know simply how onerous a few of these unsung heroes labored for therefore many a long time,” she says.
Looking for volunteers
NSIST had a low-key launch in February 2025, when some 75 folks, together with many present or former members of GCHQ, the armed forces, native corporations and high-tech companies, gathered for drinks and canapes in Cheltenham.
Jack Marley is founding father of PM3, a Cheltenham-based cyber safety firm that helped to sponsor NSIST’s low-key launch. He has a eager curiosity in historical past.
“We don’t actually do something to formally defend our heritage on this house in the intervening time, so NSIST is the primary huge effort to take a look at alerts and take a look at how intelligence works and the way we defend that, together with the remainder of our related heritage,” he tells Laptop Weekly.
Along with preserving historic websites, he says it is very important preserve a report of how folks labored and the processes they adopted previously, as that may inform options to right now’s issues.
NSIST is an opportunity to protect, preserve and rejoice an vital a part of the UK’s nationwide safety legacy, and report and share the non-public tales of those that labored in alerts intelligence and safety Gaven SmithChair of the trustees, NSIST
“It might be a type of tragedy if all these websites, processes, instruments and gear have been simply forgotten,” he provides.
Gaven Smith, a former director normal for know-how at GCHQ and now a professor of cyber safety and a non-executive director at Past Blue and different know-how centered corporations, is chair of the trustees at NSIST.
“NSIST is an opportunity to do one thing superb,” he tells Laptop Weekly. “An opportunity to protect, preserve and rejoice an vital a part of the UK’s nationwide safety legacy, and report and share the non-public tales of the 1000’s of people that labored in alerts intelligence and safety.
“It’s a probability to take care of our historical past, perceive that nationwide safety has all the time been a workforce sport, and always remember how the experiences of the twentieth century have paved the best way for the successes of right now.”
Abrutat is on the look-out for different fanatics who’re enthusiastic about historical past, communications safety and alerts intelligence to affix NSIST, attend occasions and contribute to the organisation
“Any specialists who’re deep into the communications safety world or have an curiosity in alerts intelligence would definitely be welcome,” he says.
