PRESENTER OPINION : When the Internet Goes Dark: What “Agent Sonya” Teaches Amateur Radio About Resilient Communications

/

Recent conflicts in Ukraine and across the Middle East have exposed a recurring and uncomfortable truth: when governments or military actors want to control the narrative, they don’t just shape the message—they switch off the medium. Internet shutdowns, cellular blackouts, and the targeted destruction of communications infrastructure have repeatedly severed citizen journalists from the outside world.

For a generation raised on always-on connectivity, the proposed solution is often more connectivity—satellite internet services such as Starlink. These platforms undeniably provide critical lifelines for journalists and NGOs operating in hostile environments. But from a systems engineering perspective, they introduce a familiar risk: centralisation. No matter how advanced, any network dependent on a relatively small number of ground stations, satellites, or control systems represents a potential single point of failure—whether through technical disruption, regulatory pressure, or direct attack.

So what happens when even the “backup” network goes dark?

Lessons from Agent Sonya

That question feels less theoretical when viewed through the lens of history—specifically, the remarkable story of Ursula Kuczynski, better known by her codename “Sonya,” as chronicled in Agent Sonya by Ben Macintyre.

Operating during World War II, Kuczynski was trained by Soviet intelligence not just in tradecraft, but in the technical fundamentals of radio communication. This wasn’t plug-and-play hardware. She learned Morse code to a high degree of proficiency and, crucially, how to construct and maintain her own transmitters in an era defined by vacuum tubes, unreliable components, and limited manufacturing consistency.

Despite these constraints, she successfully transmitted intelligence from within Europe—sometimes under the nose of the very regimes she was reporting on. Her work contributed to Soviet awareness of Nazi capabilities and, later, to intelligence flows that supported the USSR’s nuclear ambitions.

From a modern engineering standpoint, her setup was astonishingly resilient:

  • Decentralised hardware: self-built, portable, and replaceable

  • Protocol simplicity: Morse code (CW) requiring minimal bandwidth and infrastructure

  • Operator skill as redundancy: the human was part of the system design

There was no reliance on a global backbone. No dependency on a third-party provider. No firmware updates. Just physics, ingenuity, and discipline.

Are We Losing the Skills That Matter?

Fast forward to today, and the contrast is stark. Communications have become faster, richer, and more accessible—but also more abstracted. Layers of software, proprietary protocols, and infrastructure dependencies separate the operator from the underlying signal path.

This raises an uncomfortable question for the amateur radio community: have we traded resilience for convenience?

Amateur radio has long prided itself on being a last-resort communications medium. Yet the barrier to entry has shifted. While modern rigs and digital modes offer extraordinary capability, fewer operators are building from first principles or developing the deep RF intuition that once defined the hobby.

And yet, the tools available today are arguably more powerful than anything Kuczynski could have imagined.

CQ in the 21st Century: From CW to Digital Modes

Imagine a modern equivalent of Sonya’s setup:

  • A compact, battery-powered HF transceiver

  • A field-deployable antenna (end-fed, vertical, or magnetic loop)

  • A laptop or embedded system running digital modes

With software such as WSJT-X or FLDIGI, operators can transmit structured data over weak-signal paths using modes like FT8, JS8Call, or Olivia. These modes offer:

  • High sensitivity: successful decodes at extremely low signal-to-noise ratios

  • Error correction: robust delivery even under poor propagation conditions

  • Automation: pre-programmed messages, scheduled transmissions, and store-and-forward capability

In effect, what once required a highly trained operator manually keying Morse code can now be executed by software—faster, more reliably, and with significantly higher data throughput.

And yet, the core principle remains unchanged: radio waves are difficult to suppress completely.

Unlike centralised internet infrastructure, HF radio propagation is inherently distributed. Signals reflect off the ionosphere, traverse borders without permission, and can be received by anyone with the right equipment and knowledge.

A Thought Experiment for the Amateur Community

If a technically literate younger generation embraced amateur radio—not just as a hobby, but as a resilient communications platform—could it serve as a counterbalance to state-controlled information blackouts?

Consider a decentralised network of operators capable of:

  • Relaying structured reports from conflict zones

  • Aggregating and validating information across multiple receivers

  • Bridging RF transmissions into surviving internet endpoints elsewhere

This begins to resemble a hybrid mesh of human operators and digital systems—part radio network, part distributed intelligence layer.

It’s not without challenges. Regulatory frameworks, licensing, operational security, and ethical considerations all come into play. But from a purely technical standpoint, the capability exists today.

Back to First Principles

The story of Ursula Kuczynski is not just a tale of espionage—it’s a reminder that resilient communication is ultimately about independence. Independence from infrastructure, from centralised control, and from assumptions about availability.

For the amateur radio community, the question isn’t whether we can build faster or more efficient systems—we clearly can. The question is whether we are maintaining the skills and mindset required to operate when those systems fail.

Because history suggests they eventually will.

And when they do, the ability to send a simple CQ—whether in Morse or as a digitally encoded burst—might once again become one of the most powerful tools for telling the world what’s really happening.
