RNZ Advances Pacific Broadcasting with Transmitter Upgrade – Futureproofing Initiatives Underway

, ,

In a strategic move towards enhancing broadcasting capabilities in the Pacific region, Radio New Zealand (RNZ) has bid farewell to its long-serving 34-year-old shortwave Thompson transmitter, colloquially known as “Transmitter 1.” This transmitter, one of two facilitating analogue and digital radio broadcasts to the Pacific, has been powered down for the last time in preparation for the installation of a cutting-edge Swiss-made Ampegon shortwave transmitter at RNZ’s Rangitaiki site.

This undertaking represents a significant milestone for RNZ, which has relied on shortwave radio for the past 75 years to disseminate broadcasts across the vast Pacific. The replacement of the aging Transmitter 1 signifies a pivotal step in the futureproofing of RNZ’s service.

Installed just outside of Taupō in 1989, Transmitter 1, a 100-kilowatt Thompson unit, played a crucial role during the Commonwealth Games in Auckland in 1990. However, with the challenges posed by obsolete parts and the transmitter’s exclusive capability for analogue transmission, its replacement became imperative.

The forthcoming Ampegon shortwave transmitter, capable of both digital and analogue transmission, is en route to New Zealand after being meticulously crafted at Ampegon’s factory in Switzerland. Yet, before the new transmitter can be operational, Transmitter 1 must undergo decommissioning, with salvageable parts reserved for future use.

RNZ’s Transmission Engineer Specialist, Steve White, acknowledged the complexities of the switchover, highlighting the need to dismantle Transmitter 1 integrated into the existing building. White explained, “It will take around four weeks to completely dismantle Transmitter 1… We need to isolate the transmitter from the main switchboard, as well as drain the fluids that help cool the transmitter before breaking it into parts.”

The installation of the Ampegon transmitter is anticipated to commence in January, with an estimated six weeks for installation, six weeks for commissioning, and additional time for training. The operational date for the new transmitter is projected to be 1 May 2024.

Once Transmitter 1 is replaced, RNZ will boast two transmitters capable of both analogue and digital transmissions, ensuring a robust backup system in case of technical issues.

In the interim, RNZ Pacific Manager Moera Tuilaepa-Taylor assured that alternative means of accessing RNZ content would be communicated to all Pacific partners. While the analogue service experiences a reduction during the transition period, RNZ content can still be accessed via satellite, downloads, or livestreaming through the official website.

RNZ Chief Executive and Editor in Chief, Paul Thompson, emphasized the indispensable role RNZ plays in the Pacific region, providing critical information during events such as the Tonga eruption when undersea cables were severed. Recognizing its significance, the Government allocated $4.4 million in capital funding for a new transmitter for RNZ Pacific as part of Budget 2022, reaffirming its commitment to the international service provided by RNZ in both English and Pacific languages.

Have You Heard of Slow Morse Code? Here is all you need to know!

, ,

slow morse code nets radio

We often invite our community to write in and let us know about any interesting events. We got a great email from Mark who runs a slow morse code net every week! 

We will share his details in next week’s newsletter. Stay tuned.

Some of the younger folk in the office said, slow morse code? what is that? So we thought it was high time we created a blog on this very topic.

So, what is Morse code? It is a communication system developed in the early 1800s, that involves creating messages, where each letter of a word is sent as a sequence of dots and dashes. This system is transmitted via sound or visual signals, typically with the help of devices like telegraphs, lamps, or radios. Slow Morse code, often referred to as “QRSS” (which stands for “QR” for “to receive slower,” and “SS” for “to send slower”), is a variant of traditional Morse code designed for low-speed communication and radio enthusiasts. Here’s how it works, how to access it, and why people enjoy this hobby:

How Slow Morse Code Works

  1. Encoding: Slow Morse code uses the same fundamental principles as traditional Morse code. Letters, numbers, and symbols are represented by combinations of short signals (dots) and long signals (dashes).
  2. Speed Reduction: The primary difference is in the speed of transmission. While traditional Morse code can be relatively fast, slow Morse code is intentionally slowed down. Each character can be extended to several seconds, making it much more accessible for newcomers and hobbyists.
  3. Transmission: Slow Morse code is transmitted using radio waves or light signals. Radio enthusiasts often use specialized devices and software to encode and decode these signals.
  4. Decoding: The receiver uses a device, like the Tecsun Radios Australia SDR (Software-Defined Radio), to capture the radio signals and convert them into visual or audible Morse code.

Accessing Slow Morse Code

  1. Equipment: To access slow Morse code, you need a suitable radio receiver. Tecsun Radios Australia SDR is an example of a device that can be used for this purpose. It allows you to tune into specific frequency bands.
  2. Tuning In: With your SDR, you can select the frequency range where slow Morse code transmissions are taking place. Radio hobbyists often monitor certain bands allocated for amateur radio Morse code communication.
  3. Waterfall Display: The Tecsun Radios Australia SDR and similar devices often include a “waterfall display.” This display shows a visual representation of the spectrum over time, making it easier to identify and decode slow Morse code signals. Operators can visually follow the patterns of dots and dashes on the display.

Why People Enjoy Slow Morse Code as a Hobby

  1. Technical Challenge: Slow Morse code provides a technical challenge for enthusiasts. It requires understanding of radio equipment, propagation conditions, and signal decoding.
  2. Nostalgia: Many hobbyists are drawn to Morse code due to its historical significance in radio communication.
  3. Community: Slow Morse code has a dedicated community of enthusiasts who share information, tips, and participate in events Just like Mark’s local net we will share with you in next week’s Newsleter.
  4. Relaxation: The slow pace of Morse code can be calming for some people. It allows for a more relaxed and methodical approach to communication.
  5. Unique Skills: Learning Morse code is a unique skill, and many enjoy the sense of accomplishment that comes with mastering it.

Slow Morse code is a variant of Morse code that is enjoyed by radio enthusiasts. The slow pace, technical aspects, and sense of community make it an attractive hobby for those interested in both history and modern radio technology. The ability to watch the whole band segment on a waterfall display aids in decoding the signals, adding an extra layer of enjoyment for enthusiasts.

Meteor Shower Unveils Rare Phenomenon: Boost to DAB Signals

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?
