In a country as vast and varied as Australia, shortwave radio has long played a quiet but powerful role. It’s more than a hobby—it’s been a lifeline, a companion, and a source of connection for countless Australians, from remote stations in the outback to coastal towns and suburbs.

To celebrate that spirit, we’re sharing a short poem that reflects on what shortwave means in our wide, open landscape:

Shortwave in the Sunburnt Land

Across the bush and coastal shore,
Shortwave signals start to roar.
From foreign news to Aussie call,
It travels freely, reaching all.

We built our kits, we tuned each dial,
And found a voice from every mile.
With country vast and towns so wide,
Radio stayed right by our side.

No apps required, no cables neat—
Just radios humming to their beat.
And every net and every wave,
Connects the hearts of those who crave.

A Tradition That Endures

While technology continues to race forward, the reliability and simplicity of shortwave radio still hold strong appeal. It’s independent, it’s global, and it works where nothing else does. For many Australians, especially those living outside major cities, that matters.

Shortwave has also stayed relevant by evolving with the times. DSP receivers, digital demodulation, compact antennas and more have made it easier than ever to get started—and to keep improving.

Long Weekends on the Bands

The recent King’s Birthday long weekend was a perfect example. Across the country, enthusiasts set up antennas. Radio nets buzzed with activity. Whether chatting with mates or scanning for distant broadcasts, operators made the most of the extra time and quiet air.

There’s something especially rewarding about going portable, tuning in from under the gum trees, or checking in with your regular net from somewhere off-grid. The experience is both peaceful and powerful.

What Did You Get Up To?

Were you on the air over the long weekend? Did you try out a new antenna or tick off a DX station you’ve been chasing?

We’d love to hear your stories. Share a photo, leave a comment, or tag us online with your setup or logbook highlights.

Since World War I, governments worldwide have used shortwave radio to send encrypted messages to their operatives across the globe. The medium’s ability to cover vast distances with a relatively simple setup made it an ideal choice for clandestine communications. Correctly decoding these messages required possession of a one-time pad or codebook—a key that unlocked the seemingly random streams of letters and numbers.

During World War II, this technique became even more refined. Allied and Axis forces alike used shortwave transmissions to communicate with spies, resistance fighters, and military units. The famous Enigma machine, used by Nazi Germany, is a prime example of cryptographic innovation intersecting with shortwave radio. While the Enigma codes were famously broken by Alan Turing and his team at Bletchley Park, many other ciphers remained undeciphered, adding to the mystique of wartime shortwave cryptography.

Numbers Stations: The Enigma of Modern Cryptography

One of the most intriguing aspects of shortwave radio is the mysterious phenomenon of numbers stations. These stations transmit sequences of numbers, letters, or tones in an almost hypnotic repetition, often read by an automated or synthesized voice. Sometimes, Morse code or digital formats are used instead. Their purpose? To deliver secret instructions to intelligence operatives.

Governments from countries such as Cuba, Russia, North Korea, Israel, the USA, and even former nations like Czechoslovakia have been known to use numbers stations. These transmissions are nearly impossible to trace back to their origin, making them a highly secure and anonymous method of communication. All a recipient needs is a shortwave radio, knowledge of the transmission’s time and frequency, and the corresponding codebook to decipher the message.

Numbers stations are shrouded in mystery and have captivated shortwave enthusiasts for decades. Some of the most famous stations include the “Lincolnshire Poacher,” thought to originate from the UK, and “UVB-76,” a Russian station also known as “The Buzzer.” Their cryptic broadcasts continue to fascinate listeners, sparking countless theories and debates.
