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.

If you’ve spent any time around radios like I have, you’ll know one simple truth: when things go wrong, reliable information becomes incredibly valuable.

As we head into the 2026 bushfire season, there are already signs that Australians should be paying attention. The Bureau of Meteorology reports that winter was warmer than average across much of Australia, with many areas of eastern Australia experiencing below average rainfall and below average soil moisture. Spring is also expected to bring above average temperatures for much of the country.

Meanwhile, AFAC’s Spring 2026 Bushfire Outlook has identified an increased risk of fire across parts of New South Wales, Queensland, Tasmania, Victoria, South Australia, Western Australia and the Northern Territory, with authorities specifically encouraging communities to prepare early. 

In plain English? This is the time of year to be getting organised, not waiting until smoke is already on the horizon.

Do You Have Your Bushfire Kit Ready?

Most of us know we should have an emergency kit. The question is: when was the last time you checked it?

Batteries go flat. Torches disappear into drawers. First aid supplies expire. Water bottles get borrowed for day trips and never make it back.

Right now is the perfect time to pull the kit out and give it a complete refresh.

A good emergency kit should include:

  • Battery-powered emergency radio
  • Spare batteries
  • Power bank
  • Torch
  • First aid kit
  • Important documents
  • Medication
  • Bottled water
  • Non-perishable food
  • Mobile phone chargers
  • Whistle
  • Emergency contact list
  • Basic tools
  • Dust masks
  • Gloves

And at the very top of my list?

A reliable emergency radio.

Why An Emergency Radio Still Matters

Many people assume they’ll simply use their mobile phone in an emergency.

Sometimes that works.

Sometimes it doesn’t.

Power outages, damaged infrastructure, overloaded mobile networks and remote locations can all affect communications. During a fast-moving emergency, access to official broadcasts can be critical.

That’s where a quality emergency radio comes into its own.

A radio doesn’t rely on the internet. It doesn’t require a mobile tower nearby. It simply does what radios have always done best: deliver information when you need it most.

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.
