The recent Optus Network outage in Australia, which left over 10 million people without phone service and internet access for a prolonged nine hours, is yet another reminder of the importance of preparedness. As more Australians questioned the wisdom of relying on a single network for both home internet and mobile phone service, it’s a wake-up call for everyone to consider alternative methods of staying in touch with the outside world, like shortwave radio. In this blog, we’ll explore how this outage affected millions and how radio can be a reliable lifeline during such emergencies.
The Impact of the Optus Network Outage
The Optus Network outage had a profound impact on daily life for millions of Australians. Businesses, especially those heavily reliant on EFTPOS machines, were among the hardest hit. One hospitality business in Sydney’s inner suburbs, operating in a predominantly cashless society, saw an 80% drop in customers during the outage. For many, particularly the younger generation, who have never experienced life without a phone, it was a bewildering experience. Many of the older generation enjoyed a day off.
Preparedness is Key
Events like the Optus outage serve as a stark reminder to be prepared for any emergency event or network outage. The outage disrupted not only daily life but also critical emergency services. Some mobile phones couldn’t reach triple-0 (Australia’s emergency number), and hospitals across the country, including virtual emergency departments in remote areas, were severely impacted. Lives were at risk due to the inability to communicate with emergency services during this crisis.
Why Shortwave Radio Matters
AM, FM and Shortwave radio, a technology over a century old, demonstrated its enduring value once again during the outage.
When everything else, including the electrical grid, internet, and cell service, fails, radio stood strong. It can relay information immediately if it’s equipped with backup power, making it a reliable source of communication during emergencies.
Tips for Shortwave Radio Preparedness
- Ensure that you and your family have AM/FM/shortwave radios readily available. You never know when you might need them.
- Learn how to operate your radio. Practice tuning in and show your family and friends how to tune in to local and international stations to stay informed during an outage.
- Store your radio in an easily accessible location. In an emergency, every second counts.
- Keep your radio charged or stock up on fresh batteries to ensure it’s always ready to use.
It’s easy to take for granted in our interconnected world, but when it’s suddenly unavailable, the consequences can be dire. Shortwave radio, a time-tested technology, can be a lifeline in times of crisis, offering a reliable means of communication when all else fails. Don’t wait until you need it; be prepared, keep your shortwave radio ready, and ensure that everyone in your family knows how to use it. In a world of uncertainty, this simple yet powerful tool can make all the difference.

Shortwave radio listening, or SWLing, is a unique hobby that holds a special allure for enthusiasts. It’s a bit like finding hidden treasures in a vast, mysterious landscape, akin to discovering Easter eggs in video games. The enjoyment of SWLing stems from uncovering something that has always been there, waiting to be found, yet often overlooked or dismissed.
If you’re a dedicated shortwave radio enthusiast, you know that a significant part of the enjoyment comes from DXing. DXing, or long-distance listening, is the practice of tuning into distant radio stations, often from other countries or continents. It’s the equivalent of embarking on a grand adventure, where the reward is the joy of discovering elusive signals amidst the cacophony of static and interference. However, DXing is just the tip of the iceberg when it comes to maximizing your SWLing experience. Here, we explore additional tips to help you get the best out of your shortwave radio journey.
- Understand the Basics: The 25-30-20-25 Rule
To fully appreciate the magic of shortwave radio, it’s essential to grasp the fundamentals. SWLing is not just about the radio itself; it’s a synergy of factors that contribute to the overall experience. Imagine it like this: 25% of the magic lies in the radio you use, 30% is in your outdoor antenna setup, 20% depends on your knowledge of the right time and frequencies for listening, and the remaining 25% revolves around your location. For optimal results, invest in a good radio, set up an efficient antenna, master the art of timing, and seek out quiet places for listening.
- Dive into the Metaphorical World of SWLing
There’s a beautiful metaphorical world that can be associated with SWLing, allowing you to look beyond the surface and appreciate the deeper meaning of this hobby. Consider some of these associations:
Tuning into Enjoyable Frequencies: Just as in SWLing, in life, you can choose to tune into the enjoyable frequencies. Identify the things that bring you joy, fulfillment, satisfaction, and make a conscious effort to incorporate them into your daily routine.
Reducing Noise and Adjusting the Tuning: Life often presents noise in the form of irritations, annoyances, and distractions. Like adjusting the tuning on your radio, you can reduce this noise by addressing these irritations and finding ways to enhance your comfort and enjoyment.
The Tuning Is Off: Sometimes, the outcomes in life may not align with your desired goals. Just as in SWLing, where the tuning can be slightly off, in life, you may need to recalibrate your efforts and strategies to get closer to your desired outcomes.
Incorporating these metaphorical perspectives into your SWLing experience can add depth and meaning to your hobby, helping you draw parallels between the art of listening to shortwave radio and the art of living a fulfilling life.
SWLing is a journey of exploration, both in terms of uncovering hidden radio signals and discovering the subtle, metaphorical messages it holds for our lives. By understanding the 25-30-20-25 rule, investing in quality equipment, and embracing the metaphorical aspects, you can truly unlock the magic of shortwave radio and enjoy the profound rewards it offers. So, keep tuning in, and let the hidden secrets of the shortwave world continue to captivate your imagination and enrich your life.
The night sky often looks incredible, but on the night of August 12, 2023, one Finnish DX (long-distance radio) enthusiast, Koe Kone, experienced an unexpected twist during the annual Perseids meteor shower. While gazing at the streaking meteors, Kone discovered a boost in German DAB (Digital Audio Broadcasting) signals, marking the first-ever documented instance of meteor-induced interference on VHF band III DAB signals.
Koe Kone, a dedicated DX hobbyist based in Turku, Finland, enjoys the challenge of seeking out distant broadcast signals. His YouTube channel showcases a treasure trove of recordings capturing broadcasts from across the Baltic Sea and beyond. However, it was during the meteor shower’s peak activity that Kone stumbled upon a radio phenomenon that had eluded detection until now.
The notion that atmospheric and celestial conditions can influence radio broadcasting is not a novel one. For decades, radio enthusiasts have observed the impact of meteor showers on radio signal propagation. Differences in the ionosphere between day and night have been known to affect the reach of AM signals, while temperature inversions in the troposphere can cause FM signals to ‘skip’ to distant markets.
As early as the 1930s, researchers recognised that meteor showers played a role in radio signal propagation. Enthusiasts and amateur radio operators have even used FM receivers to eavesdrop on meteor showers.
Kone’s groundbreaking discovery was made possible through his use of an Airspy Mini scanner and QIRX SDR software for signal reception. He paired these tools with a formidable 13-element VHF band III yagi antenna positioned at a lofty 48 meters above sea level. This setup allowed Kone to successfully receive and decode a signal emanating from a German multiplex operating in block 5C.
Intriguingly, Kone’s decoded stations led him to identify five potential transmission sources in Germany: Casekow, Pritzwalk, or Templin in Brandenburg; Röbel, Rostock, or Züssow in Mecklenburg–Vorpommern; and Garz on the picturesque island of Rügen, also situated in Mecklenburg–Vorpommern. Astonishingly, the closest of these sites is approximately 800 kilometers (nearly 500 miles) away from Kone’s reception site in southwestern Finland.
During the peak of his listening experience on August 12, Kone’s receiver displayed three adjacent DAB multiplexes on blocks 5B, 5C, and 5D. Although he couldn’t decode all the signals, he did capture brief bursts from blocks 5C and 5D in the early hours of August 11.
Sharing his discovery with the “DAB/DAB+ Digital & Online Radio” Facebook group, Kone reflected on his past successes in capturing Swedish DAB stations. However, the meteor shower recording was different. He noted, “This in the video was quite different, being a meteor scatter and lasted only a few seconds.”
Koe Kone’s discovery serves as a testament to the wonders that can be unveiled when technology, passion, and the mysteries of the cosmos converge. The meteor-induced boost to DAB signals not only adds a new layer of intrigue to the world of DX enthusiasts but also reminds us of the possibilities to discover. As we continue to explore the radio spectrum, who knows what other cosmic secrets may await discovery in the silent spaces between the stars?
