Amateur Radio Users Involved in Intelligence Gathering: conflict using ham radio communications
Hear me out, folks: What's the bass-ass secret ingredient for a smackin' good fishing trip? The hoi polloi might say it's about the tackle, the location, or even a cold one. But let's face it, without those wriggly creatures in your cooler, you're just out for a boat ride. And this ain't no pleasure cruise, people, we're talking war here.
Mind-blowing fact: While you were playing with your Nightcrawlers, the Brits during WWII were grappling with a different kind of catch—enemy radio transmissions. Picture this: they knew the Axis powers were blabbing their guts out on the airwaves, but they couldn't snoop in on every little gabfest without an ear on every radio. That's where Alan Turing and the boys at Bletchley Park are usually mentioned. But there's another crucial crew you might not be familiar with—the unsung heroes at Arkley View.
The not-so-subtle hint of the looming war made the Brits realize they needed backup on the radio-listening front. Colonel Adrian Simpson highlighted the need for a network of civilian volunteers to take on the interception duties. And in 1938, the Radio Security Service (RSS) was born, squatting in some unused prison cells in London. The team initially called on experienced ham radio operators to help spy on home-grown enemy agents. And, when the war kicked off, the government confiscated their transmitters but kept their receivers and Morse code savvy—essential tools for listening in on the enemy.
The RSS soon ballooned to about 1,500 members, vetting their volunteers through MI5 and local cops to ensure they weren’t spies themselves. These volunteers were tasked with logging messages from unidentified stations and sending them to the RSS team to decrypt.
Fast forward to the early days of the war, and the RSS managed to decode messages traded between European agents and their Abwehr handlers in Germany. After some code-breaking successes, they started concentrating on the Abwehr and their rivals, the Sicherheitsdienst. In 1941, MI6 took over the RSS and renamed them SCU3 to manage foreign radio traffic.
But these spies had to work smart and not just hard. They developed their own direction-finding techniques to narrow down enemy transmission locations and monitored log-ins from hundreds of volunteers to sift through the noise and find valuable messages.
Fun fact: One of these RSS members, a bedridden war vet, managed to record an important 4,429-character message using mirrors and control extensions. He even scored a British Empire Medal and a personal thank-you note from Churchill for his services.
In the end, all this snooping paid off: the Brits intercepted messaging between spies and their agents before they ever set foot on English soil, turning many of them into double agents. By the war's end, the RSS had decoded around a quarter of a million intercepts. Smart as a fox, MI5 realized they could use a large number of trained radio operators to blanket the country with receivers and free up military stations for other missions.
And if you thought this was all a UK thing, think again: even the FCC had a similar plan going on stateside.

As the Brits prepared for war, they turned to civilian volunteers, forming the Radio Security Service (RSS), whose task was to decode enemy radio transmissions.
The RSS successfully intercepted and decoded messages between spies and their agents, preventing many from reaching English soil and turning several into double agents, demonstrating the crucial role of technology, like ham radios, in the war effort.
