Australian Emergency Preparedness: Have We Become Too Reliant on Being Connected?

, , , , ,

If you’ve been paying attention to the news lately, you’ve probably noticed a growing trend.

Governments, emergency agencies and infrastructure experts around the world are increasingly encouraging people to think about preparedness. Not panic. Not fear. Just preparedness.

For many older Australians, this isn’t a new concept.

Most of us remember a time when homes kept extra food in the pantry, spare batteries in the cupboard and a reliable radio on the shelf. We didn’t call it “prepping”. It was simply common sense.

Today, however, our lives are more connected than ever before.

We rely on mobile phones, internet banking, GPS navigation, online shopping and digital communication for many everyday tasks. While these technologies make life easier, they also create a new challenge. What happens if those systems become unavailable, even temporarily?

Recent years have shown how quickly disruptions can occur. Floods, bushfires, severe storms and power outages have affected communities across Australia. Increasingly, experts are also raising concerns about cyber attacks and vulnerabilities affecting essential services and communications.

No one is suggesting we should expect the worst. In fact, most emergencies are localised and short-lived. However, having a basic emergency kit and a simple plan can make a significant difference during unexpected events.

The Modern Emergency Kit

Many Australians already keep some emergency essentials at home. A well-prepared emergency kit might include:

  • Drinking water
  • Non-perishable food
  • Prescription medications
  • First aid supplies
  • Battery-powered torches
  • Spare batteries
  • Important documents
  • Power banks for charging devices
  • Emergency radio

While smartphones are wonderful tools, they depend on functioning networks and charged batteries. In a prolonged outage, alternative sources of information become incredibly valuable.

Why Radio Still Matters

Even in our highly connected world, radio remains one of the most resilient forms of communication ever developed.

When severe weather, natural disasters, prolonged power failures or cyber incidents disrupt normal communications, radio can continue delivering vital information long after internet services and mobile networks become unavailable.

Most Australians are familiar with AM and FM broadcasting, but fewer people realise the important role that Shortwave radio can also play during major emergencies.

AM Radio: The Local Lifeline

AM radio has long been considered one of Australia’s most important emergency communication platforms. Because AM signals can travel hundreds of kilometres, particularly at night, they can continue reaching communities even when local infrastructure has been damaged.

Many listeners rely on stations such as:

  • ABC Local Radio
  • ABC Emergency broadcasts
  • State emergency service updates
  • Rural and regional AM broadcasters

During bushfires, floods, cyclones and severe storms, these stations are often among the first sources of official information and evacuation advice.

Why Shortwave Still Matters

While Shortwave broadcasting is no longer as common as it once was, it remains one of the few communication systems capable of reaching across states, countries and even continents without relying on internet infrastructure.

Unlike mobile phone services, satellites, fibre optic networks and internet platforms, Shortwave signals travel through the atmosphere and can often be received thousands of kilometres from their source.

In a widespread communications outage, a Shortwave radio may allow you to receive news and information from broadcasters far beyond your local region.

Depending on conditions, Australian listeners can often receive international broadcasters such as:

  • BBC World Service
  • Radio New Zealand Pacific
  • China Radio International
  • Voice of Vietnam
  • Voice of Korea
  • Radio Romania International
  • NHK World Japan
  • Various amateur radio emergency networks

Historically, Shortwave has been used during major disasters, military conflicts, humanitarian emergencies and large-scale power outages because it can operate independently of local communications networks.

Cyber Attacks Are A Modern Concern

For many years Australians primarily thought about bushfires, floods and storms when preparing emergency kits.

Today there is another consideration.

Governments and security experts increasingly discuss the risk of significant cyber attacks targeting critical infrastructure including telecommunications, energy networks and essential services.

While nobody can predict what future events may occur, maintaining access to independent information sources remains a sensible precaution.

That’s one reason many preparedness experts continue to recommend keeping a battery-powered or hand-crank radio as part of every emergency kit.

When mobile coverage drops out, the internet becomes inaccessible, or power remains unavailable for extended periods, radio may become one of the simplest and most reliable ways to stay informed.

Introducing the New “Guardian” Emergency Radio

If you’re reviewing your emergency kit this year, Tecsun Radios Australia is pleased to announce the upcoming release of the new Guardian Q3003 Emergency Radio.

Available from 9 November 2026, the Guardian has been designed with practical preparedness in mind.

Unlike many emergency radios currently available, the Guardian includes AM, FM and Shortwave reception, giving users access to local, national and international broadcasts when they matter most.

Priced at $115, key features include:

  • AM / FM / SW radio coverage
  • Shortwave bands for long-distance reception
  • Large, easy-to-read LCD display
  • Dual speaker design
  • Automatic frequency scan function
  • Rechargeable internal lithium-ion battery
  • AAA battery backup operation
  • Solar charging panel
  • Hand-crank charging capability
  • Emergency siren
  • Personal locator function
  • LED torch
  • Floodlight
  • USB phone charging capability

One feature we particularly like is the flexibility. Whether you’re camping, travelling, experiencing a power outage or simply preparing for emergencies, the Guardian offers multiple charging options and multiple ways to stay informed.

Preparation Is About Peace of Mind

None of us can predict the future.

Most likely, your emergency kit will sit quietly in the cupboard and never be needed. That’s actually the best outcome.

But if a severe storm cuts power to your neighbourhood, if communications are disrupted, or if an emergency affects your region, you’ll be glad you took a few simple steps beforehand.

Preparedness isn’t about panic.

It’s about peace of mind.

And sometimes, something as simple as a reliable radio can make all the difference.

The Guardian Q3003 Emergency Radio will be available from Tecsun Radios Australia from 9 November 2026 for $115.

Stay informed. Stay connected. Stay prepared.

Using the Tecsun SDR to Evaluate HF Propagation Around the World

, , ,

For many shortwave listeners and amateur radio operators, the Tecsun Radios Australia SDR is a valuable tool for tuning into signals that may be impossible to hear from their own location. Whether you’re listening to international broadcasts or monitoring amateur radio activity, the online receiver opens up a world of listening opportunities.

What many users may not realise, however, is that the Tecsun SDR can also be used as a highly effective HF propagation monitoring tool thanks to its integrated International Beacon Project (IBP) extension.

What is the International Beacon Project?

The International Beacon Project (IBP) is a worldwide network of 18 continuously operating CW beacons managed by the Northern California DX Foundation (NCDXF). These stations are strategically located across the globe and transmit continuously on a rotating schedule across five amateur radio bands.

By monitoring which beacons can be

 heard and at what signal strengths, radio operators can gain valuable insight into current propagation conditions between different parts of the world.

Accessing the IBP Scan on the Tecsun SDR

Using the feature is straightforward.

Simply select “IBP Scan” from the “Extensions” menu within the Tecsun SDR interface. The receiver will then display a series of thumbnail spectrum windows while automatically scanning all 18 beacon locations.

By observing the spectrum displays and listening to the CW transmissions, users can assess how well radio signals are travelling fro

m various regions of the world to the SDR receiving site.

Beacon Locations Around the World

The IBP network includes stations in:

  • New York City, USA (4U1UN)
  • Canada (VE8AT)
  • California, USA (W6WX)
  • Hawaii (KH6RS)
  • New Zealand (ZL6B)
  • Perth, Australia (VK6RBP)
  • Japan (JA2IGY)
  • Siberia (RR9O)
  • Hong Kong (VR2B)
  • Sri Lanka (4S7B)
  • South Africa (ZS6DN)
  • Kenya (5Z4B)
  • Israel (4X6TU)
  • Finland (OH2B)
  • Madeira (CS3B)
  • Argentina (LU4AA)
  • Peru (OA4B)
  • Venezuela (YV5B)

Because these beacons are spread across every inhabited continent, they provide an excellent snapshot of global HF conditions at any given time.

Beacon Frequencies

Each beacon transmits on five amateur bands:

At any given moment, five different beacons are transmitting simultaneously, one on each band.

Understanding the Transmission Sequence

Each beacon transmits for a 10-second cycle before the next beacon takes its turn.

During this sequence, transmission power is progressively reduced to help listeners judge path quality:

  • 0 to 5.5 seconds: Callsign transmitted in CW at 22 WPM using 100 watts
  • 5.5 to 6.5 seconds: Long dash at 10 watts
  • 6.5 to 7.5 seconds: Long dash at 1 watt
  • 7.5 to 8.5 seconds: Long dash at 100 milliwatts
  • 8.5 to 9.5 seconds: Long dash at 10 milliwatts
  • 9.5 to 10 seconds: Silent period before the sequence repeats

The lower-power dashes are particularly useful. If you can still hear the beacon at 100 milliwatts or even 10 milliwatts, it indicates an exceptionally strong propagation path between the beacon location and the receiving station.

What Can You Learn?

The beauty of the IBP system is that it transforms the SDR into a real-time propagation monitoring station.

For example:

  • Strong signals from North America may indicate favourable trans-Pacific conditions.
  • Improved reception from Europe can signal an opening on higher-frequency bands.
  • Weak or absent signals from traditionally reliable stations may suggest deteriorating propagation due to geomagnetic activity or changing solar conditions.
  • Comparisons between bands can reveal which frequencies are currently performing best for long-distance communication.

For amateur radio operators planning DX contacts, this information can be invaluable in choosing the optimal band and time to operate.

A Powerful Tool Hidden in Plain Sight

Many listeners use the Tecsun SDR solely as a remote receiver, but the built-in IBP Scan extension offers a fascinating way to study HF propagation in real time. By monitoring beacon activity from 18 locations around the world and observing how signal strengths vary across five amateur bands, users can develop a deeper understanding of the constantly changing nature of the ionosphere.

Whether you’re a seasoned DXer, a contest operator, or simply curious about how radio waves travel around the globe, the IBP Scan feature is well worth exploring.

When Dad Taught Us to Listen to the World

, ,

Before smartphones, streaming and YouTube, there was the radio. For generations, fathers and children discovered the wider world together by turning a dial.

There are some sounds that seem to belong to another time.

The gentle click of a tuning knob.

A little static between stations.

The crackle of a distant voice suddenly emerging from the noise.

And perhaps, somewhere in the background, the familiar voice of Dad saying, “Wait… I think I can get it.”

For generations, radio was more than a way of listening to music or the news. For many families, it was a doorway to curiosity — and for countless children, it was a hobby introduced by a father, grandfather or another patient adult who was willing to show them how it all worked.

This Father’s Day, we thought we’d look back at that connection between fathers, children and radio, and at the remarkable way a little box with a dial could open up an entire world.

When radio was something you learned, not just something you listened to

In 1935, American radio enthusiast and writer John T. Frye wrote an article called “Why Your Son Should Learn Radio” in Short Wave Craft.

The premise is wonderfully old-fashioned, but the reasons he gives for learning radio still feel surprisingly familiar today.

Frye was trying to persuade a father that his son’s fascination with amateur radio wasn’t simply a passing distraction. He argued that radio encouraged young people to use their hands and minds, develop practical skills and learn through experimentation.

He even described how a young boy could become so absorbed in radio that it kept him happily occupied at home.

Perhaps the most charming part of the story is that Frye wasn’t simply talking about radio in the abstract. He was mentoring a young boy named Jack and trying to convince Jack’s father that this strange new hobby was actually something worth encouraging.

It is a lovely reminder that some of the best gifts a parent can give aren’t things at all — they’re interests, skills and a sense of curiosity. (Tecsun Radios Australia)

Dad’s radio could take you somewhere

Shortwave added another layer of magic.

Unlike the local AM stations most families knew, shortwave could bring voices and broadcasts from remarkably distant places. With the right conditions, a listener could sit at home and hear another country on the other side of the world.

And Australia has its own fascinating place in this story.

In September 1927, Australia’s first major international shortwave broadcast was transmitted from Sydney towards England. The broadcast, known as the Empire Broadcast, used a powerful AWA transmitter at Pennant Hills and included speeches and music from Australian performers. For listeners in Britain, a signal travelling from Australia across the world must have seemed almost magical. (Radio Heritage Foundation)

Imagine being a child sitting beside your father in the 1920s or 1930s, listening to a voice arriving through the speaker from thousands of kilometres away.

The world suddenly wasn’t quite so big.

The memories that stay with us

Search through radio communities today and you’ll find that the connection between fathers and shortwave hasn’t disappeared.

One listener remembers sitting with his father and brother as they listened to the BBC World Service while living overseas. The distant voices from home became a treasured childhood memory and eventually inspired his own journey into amateur radio. (G0RIF)

Another recalls his father regularly tuning a shortwave set, listening for time signals and enjoying the remarkable precision of receiving broadcasts from far away. (I Remember JFK)

And there are countless similar stories shared by radio enthusiasts: fathers passing down old receivers, children becoming fascinated by the sounds hidden between stations, and families discovering together that there was much more to radio than the stations they could hear locally.

One particularly touching modern shortwave community story came from someone who inherited his father’s radio after his father passed away. He described continuing to listen to the shortwave bands as a way of remembering him — saying that hearing the radio made him feel as though he was back with his Dad. (Reddit)

Perhaps that’s one of the special things about radio.

It can become part of a memory.

The technology has changed. The feeling hasn’t.

Today, we can instantly video call someone on the other side of the world.

We can stream almost any song ever recorded.

We can ask our phones what is happening in another country.

But there is something wonderfully different about discovering a distant signal yourself.

Turning the dial.

Listening through the static.

Wondering where the voice is coming from.

Finding a station you weren’t expecting.

For shortwave listeners, that sense of discovery is still very much alive.

And modern portable radios make it easier than ever to take that experience outside — into the backyard, onto the balcony, camping, travelling or simply sitting beside Dad with a cup of coffee.

Maybe that’s why radio continues to appeal across generations.

It’s not just about receiving a signal. It’s about discovering something.

And discovering something together is one of the things we remember.

This Father’s Day, turn the dial

Perhaps your Dad introduced you to radio.

Perhaps you remember sitting beside him while he listened to the news, sport or music.

Perhaps there was an old radio in the workshop that you were never quite allowed to touch.

Or perhaps you’re the Dad now — and there’s a curious young person in your life who wants to know what all those buttons and dials actually do.

If so, this Father’s Day might be the perfect time to sit down together, turn the dial and see what you can find.

Because the best part of radio isn’t necessarily knowing what you’ll hear.

It’s not knowing.

And sometimes, that’s where the adventure begins.

From all of us at Tecsun Radios Australia, Happy Father’s Day.

Here’s to the Dads who taught us how to listen — and to the next generation discovering the world for themselves.

 

Further reading

A few years ago, we explored this subject from a slightly different angle in our Father’s Day article, “In the Spirit of Father’s Day – Why Your Son Should Learn Radio”, looking back at John T. Frye’s fascinating 1935 article and his arguments for encouraging young people to take up radio.

Shortwave in 2025 — The Airwaves Are Alive Again

, , , ,

Shortwave is far from silent.

From new transmitters humming to life in the Pacific, to hobbyists catching signals from the other side of the world, there’s been plenty happening lately on the bands. Here’s a look at some of the most interesting updates.

New Voices on the Airwaves: Shortwave Australia

Over the past few weeks, a station identifying itself as Shortwave Australia has been heard broadcasting on 2310 kHz and 4835 kHz. Reports from listeners across the country describe strong signals and a program of nostalgic, old-time music drifting across the dial — a refreshing discovery for anyone who enjoys exploring the lower shortwave bands.

While official details are limited, a growing number of hobbyists have confirmed regular activity on these two frequencies. The station’s broadcasts have been logged during afternoons and evenings (local time), with 4835 kHz often producing the strongest results in daylight hours before fading around dusk. At night, 2310 kHz seems to take over, offering surprisingly consistent reception when conditions are right.

Programming so far appears to focus on music and general entertainment, with minimal announcements or station IDs — a style that gives the broadcasts a distinctly nostalgic feel. Listeners have described the experience as “like tuning into a forgotten corner of the radio world.”

Online, discussions about the station have started to appear on hobby forums and monitoring blogs, where enthusiasts are sharing signal reports, audio clips, and reception logs. Some have uploaded recordings to YouTube and SDR platforms, while others are tracking the station on sites like Shortwave.Live, which lists it as active on both frequencies around the clock (though actual transmission times vary).

Want to Try Your Luck Tuning In?

🎧 When to listen: Afternoon or early evening — that’s when most recent reports have been logged.
📻 Frequencies to check: Start with 4835 kHz, then try 2310 kHz later in the night.
🔌 Reception tip: Use a loop or long-wire antenna placed well away from household noise sources.
🌐 Online option: Explore KiwiSDR receivers around Australia to see how the signal propagates in different regions.

We’d Love to Hear From You

Have you caught Shortwave Australia on the dial? What times, signal strengths, or music have you logged?

If you’ve captured a short audio clip or screenshot, share it with us — we may include listener reports in a future blog post to help map out the station’s reach and schedule.

Shortwave lives on through discoveries like this, and with help from the listening community, we can keep these new voices heard far and wide.

China Goes Digital

China has formally adopted DRM (Digital Radio Mondiale) as its national standard for shortwave and mediumwave broadcasting. The move could transform the listening experience, offering FM-quality sound and data broadcasting across vast distances.

Pacific Coverage Expanding

RNZ Pacific has completed a major transmitter upgrade near Taupō, New Zealand, installing a new 100 kW Ampegon TSW-2100 unit supporting both analog and DRM signals.

At the same time, Papua New Guinea has announced plans to reintroduce shortwave broadcasts to improve coverage for its remote communities — an encouraging reminder that shortwave still matters, especially where the internet can’t reach.

Vanuatu: Back on the Bands

VBTC has announced new shortwave frequencies of 2485, 3945, 5040, 7260, and 9960 kHz.
The 9960 kHz signal has been heard regularly along the east coast of Australia, with a transmitter power of 10 kW.

Technology Meets Tradition

Researchers have even turned to AI, developing systems that can automatically classify hundreds of shortwave signal types using deep learning.

Meanwhile, mysterious stations like UVB-76 (“The Buzzer”) continue to intrigue listeners and keep the global shortwave conversation alive.

Explore, Learn, and Listen

On the Airwaves: Honouring History in the 2025 Remembrance Day Radio Contest

, ,

Each year, thousands of Australian amateur radio operators power up their rigs in mid-August—not just for the thrill of making contacts, but to honour a legacy.

This year’s Remembrance Day Contest will be held over the weekend of August 16–17, bringing together radio amateurs across VK, ZL and P29 call areas for one of the most meaningful events in the amateur radio calendar.

A contest with purpose

The Remembrance Day (RD) Contest is more than just a weekend of callsigns and contacts. It was first introduced in 1948 by the Wireless Institute of Australia (WIA) as a way to commemorate amateur radio operators who lost their lives during World War II.

The timing is symbolic—it takes place on the weekend closest to August 15, the date on which hostilities ceased in the Southwest Pacific in 1945. Each year, the contest brings the amateur radio community together to remember, reflect, and enjoy a spirit of friendly on-air competition.

How the contest works

The aim is simple: make contact with as many stations in VK, ZL and P29 as possible, on all amateur bands excluding the WARC bands (10, 18 & 24 MHz), and using traditional modes such as:

  • PHONE

  • CW (Morse Code)

  • RTTY (Radio Teletype)

Operators can use MF (160 metres), HF, and VHF & above. Whether you’re chasing contacts or logging them as a Shortwave Listener, it’s a great weekend to hone your operating or listening skills.

Tips for shortwave listeners

SWLs can join in the fun by tuning into these frequencies during the contest:

160m: 1843–1875 kHz
80m: 3535–3570 kHz and 3600–3700 kHz
40m: 7080–7300 kHz
20m: 14112–14300 kHz
15m: 21150–21450 kHz
10m: 28300–29100 kHz

It’s the perfect opportunity to test your antennas, refine your logging, and experience the buzz of a live contest weekend.

Shortwave in the Sunburnt Land

, , ,

How Australians Continue to Make This Hobby Their Own

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.

Shortwave in Australia isn’t going anywhere—and with every new voice on the dial, it continues to grow.

Shortwave Radio and Cryptography: The Secret Side of the Airwaves

Shortwave Radio and Cryptography: The Secret Side of the Airwaves

Shortwave Radio and Cryptography: The Secret Side of the Airwaves

Shortwave radio is a fascinating medium that has connected people across the globe for decades. It’s not just a platform for international broadcasters, amateur operators, and hobbyists—it also has a history steeped in mystery and secrecy. Welcome to the hidden world where shortwave radio and cryptography intersect, revealing a legacy of coded wartime messages, enigmatic numbers stations, and the enduring allure of decoding the unknown.

Cryptography Over the Airwaves: A Brief History

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.
