    The UBCD436PT supports P25 Phase I and II, DMR, and NXDN digital trunking protocols, which are increasingly used by emergency services. This ensures future-proof compatibility as older analog systems are phased out.
    A paid upgrade is required to unlock both DMR and NXDN modes.

  2. Dynamic Memory Architecture:
    Its memory system allows for easy organization of frequencies into customizable banks, offering flexibility over traditional fixed-channel scanners. The Sentinel software further simplifies programming and updating.

  3. Built-In Database:
    With access to the Australian Radioreference database, users can quickly locate nearby frequencies, making it user-friendly for those less experienced in manual programming. In our cases, this is not a great source of up to date information and manual programmed is required to get the most from the UBCD436PT.

  4. Close Call RF Capture:
    This feature detects and tunes into nearby transmissions instantly, ideal for field monitoring or events with high RF activity.

  5. Customizable Scanning:
    The inclusion of service search categories like public safety, marine, aviation, and railroads makes this scanner versatile for hobbyists and professionals alike.

  6. GPS Compatibility:
    With an external GPS module, the scanner can automatically adjust the scanning list based on your location, a boon for those on the move.

Pros

  • Wide Frequency Coverage: Covers 25-1300 MHz (with gaps) to monitor everything from HF aviation to UHF emergency services.
  • Compact and Portable: Designed for handheld use, it’s suitable for mobile scanning or casual field trips.
  • Upgradeable Firmware: Regular updates ensure the device remains compatible with changing communication protocols.
  • Excellent Audio Quality: Loud and clear audio ensures transmissions are easily heard even in noisy environments.
  • Customizable Alerts: The LED alert and tone options help quickly identify the source of an active frequency.

Cons

  • Steep Learning Curve: Beginners may find the array of features overwhelming without prior experience in scanners.
  • Limited Battery Life: The supplied AA NiMH batteries provide only 6–8 hours of use, which could be insufficient for long scanning sessions.
  • Price: At around $650 AUD, the UBCD436PT is an investment, though justified by its capabilities.
  • Build Quality: While functional, the plastic casing feels less rugged compared to some competing models.
  • Challenging DMR Setup: Some users report difficulty programming DMR systems without significant manual adjustments.

Ideal Use Cases

  • Public Safety Monitoring: Its ability to decode trunked systems ensures you won't miss critical communications.
  • Hobby Scanning: Aviation, rail, marine, and CB enthusiasts will appreciate its broad coverage and ease of use.
  • Event Monitoring: The Close Call feature is great for events with unpredictable RF activity.

Final Thoughts

The Uniden UBCD436PT is one of the best handheld scanners on the Australian market for advanced users and professionals who need comprehensive digital and analogue scanning capabilities. While it may not be the easiest to master for newcomers, its powerful features and future-ready support for digital protocols make it a worthwhile investment for anyone serious about radio monitoring.

TASGRN Information

Background:

TASGRN: Modernizing Emergency and Government Communications in Tasmania

Tasmania, Australia's island state, is no stranger to the challenges of communication in its rugged landscapes. The Tasmania Government Radio Network (TASGRN) is a groundbreaking initiative aimed at creating a unified, reliable communication system for emergency services, government agencies, and other critical stakeholders.

What is TASGRN?

The TASGRN is a state-wide digital radio network designed to bring together disparate communication systems under a single, cohesive platform. The project, backed by significant investment from the Tasmanian Government, uses advanced digital technologies to provide better coverage, interoperability, and resilience.

Currently, many agencies in Tasmania, including police, fire, ambulance, and various government departments, rely on separate communication networks. These systems often have compatibility issues, limited range in remote areas, and insufficient capacity during emergencies. TASGRN addresses these issues by ensuring all parties can seamlessly communicate when it matters most.

Key Features of TASGRN

  1. Digital Trunking Technology
    TASGRN employs Project 25 (P25) Phase 2 technology, a standard used globally for critical communications. This provides:

    • Better spectrum efficiency: More users can operate simultaneously.
    • Clearer audio quality: Reduced background noise and distortion.
    • Improved security: Encryption ensures secure communication.
  2. State-wide Coverage
    The network is designed to cover even Tasmania's most remote areas. By using strategically placed towers and leveraging UHF and VHF bands, TASGRN will ensure reliable communication for on-the-ground teams and headquarters.

  3. Interoperability
    One of TASGRN’s standout features is its ability to integrate multiple agencies into a single system. This interoperability ensures seamless communication between police, ambulance, fire services, and others during emergencies like bushfires, floods, and search-and-rescue operations.

  4. Scalability and Future-Proofing
    TASGRN is built to adapt to future technological advancements. The infrastructure is designed to support upgrades, ensuring it remains effective for decades.

Why is TASGRN Important?

  1. Emergency Response: In crises, quick and reliable communication can save lives. TASGRN ensures that all agencies can coordinate effectively without delays caused by incompatible systems.
  2. Cost Efficiency: By consolidating multiple systems into one, TASGRN reduces the long-term costs associated with maintaining separate networks for different agencies.
  3. Resilience: The system is designed to withstand natural disasters, ensuring communication remains operational when other systems might fail.
  4. Support for Daily Operations: Beyond emergencies, TASGRN provides a robust platform for everyday tasks, improving efficiency across government agencies.

Challenges and Implementation

Deploying TASGRN is no small feat. It involves upgrading existing infrastructure, training staff to use new equipment, and ensuring minimal disruption during the transition. Despite these challenges, the benefits far outweigh the short-term hurdles.

How Will It Impact Communities?

For everyday Tasmanians, the benefits of TASGRN might not always be visible but are deeply impactful.

  • Safer communities: Faster, more coordinated responses to emergencies mean better outcomes.
  • Improved infrastructure: Investments in communication towers and systems also boost mobile and internet connectivity in remote areas.
  • Economic benefits: By modernizing infrastructure, Tasmania becomes more attractive for investments and tourism.

Conclusion

The TASGRN is a transformative project that underscores Tasmania's commitment to modernizing its emergency and government communication systems. By investing in this cutting-edge network, the state is enhancing safety, efficiency, and resilience for years to come.

As Tasmania’s landscape continues to challenge emergency responders, TASGRN is a crucial step toward ensuring that help is always just a call away—no matter where they are.

Short Story - The Midnight Whisper



Elliot sat in his dimly lit room, the soft hum of his old scanner filling the silence. The world outside was dark, the neighbourhood quiet, but for him, the night was alive with possibility. His fingers hovered over the tuning knob, ready to catch the faintest whisper in the air.

Radio scanning had been his passion since he was a boy, when his grandfather gifted him his first handheld scanner. Over the years, Elliot had upgraded to more sophisticated equipment, piecing together a setup that could pluck signals from across the globe. Each night, he embarked on a new journey, tuning into the unseen world of airwaves.

The scanner hissed and popped as he turned the dial. Static ebbed and flowed like the tide, a symphony of chaos that only he could love. Then, a voice broke through the noise, crisp and clear:

“November Delta 324, requesting descent to 10,000 feet.”

Elliot smiled. A commercial flight heading into the local airport. He imagined the passengers, weary from their journey, peering out at the city lights below. But he didn’t linger on the thought. There were more secrets to uncover.

He switched bands, chasing bursts of signal. A weather report from a distant marine station crackled through, warning of rough seas. Then came the rhythmic chatter of a train dispatcher coordinating with an engineer. Elliot jotted down the frequency in his notebook, a habit he’d kept for years.

Suddenly, a faint, rapid burst of static caught his ear. He adjusted the dial with precision, leaning closer to the receiver. A series of beeps and tones followed—a Morse code transmission. Elliot’s heart quickened. These were rare finds.

Deciphering the code, he scribbled on a notepad:
CQ DX. It was a general call for distant stations, sent from an amateur radio operator somewhere far away. Elliot responded silently in his mind, imagining the operator on the other end, sitting in their own quiet room, searching the skies just as he was.

The night stretched on, and Elliot continued his exploration. Each signal was a fragment of a story: a taxi dispatcher coordinating pickups, a ham operator recounting his day, a distant broadcast of a soccer match from halfway across the world.

As dawn broke, the scanner’s hum faded into the background, blending with the first chirps of waking birds. Elliot leaned back in his chair, his notebook filled with new frequencies, his mind alight with the connections he had made.

For most, the airwaves were invisible, intangible. But for Elliot, they were a bridge to a vast, unseen world—a reminder that even in solitude, he was never truly alone.

A Unique Radio Day: Logging New and Rare Frequencies

December 4th, 2024, was a standout day in my radio scanning journey. It’s not every day that you manage to log a brand new frequency, let alone several rare or previously inactive ones. From unexpected transmissions to reactivated channels, the day was full of discoveries that made it one for the books. Here's a rundown of the frequencies I logged, including the stories behind them.

1. 462.125 - UHF Simplex: A New Frequency Logged
The day started off with a breakthrough—a brand-new frequency logged for the first time on my scanner: 462.125 MHz in the UHF Simplex range.

This was an exciting moment, especially since it's not common to stumble across completely new frequencies active these days. The log occurred in Riverside. The voices on the airwaves seemed to belong to school staff (we have have four schools in this area), possibly communicating logistics related to events or coordination. This is a unique find, as it’s likely this frequency hasn't been used much, if at all, before. A moment of serendipity! I now have added this to my dedicated UHF wideband handheld, to keep a closer ear out for it's use.

2. 465.4 - CSE Cross Com: A Re-emerging Frequency
Next, I logged 465.4 MHz on a frequency that hadn’t been heard in my logs since 2017. It’s always intriguing when an old frequency comes back to life, and on 04/12/2024 at around 9:30 PM, it was very active.

The transmissions on this frequency appeared to come from a security company, with the callsigns "Tango Alpha Base" and "Tango Alpha 1,2,3" being repeated frequently. There was also a series of "Copy your Charlie 1,6,7" exchanges, indicating some kind of operational communication, possibly related to security patrols or site monitoring.

This type of activity is rare, and the frequency's re-emergence after years of dormancy is fascinating. It was a reminder of the constant ebb and flow of radio communications, where channels sometimes go quiet for years and suddenly spring back into action.

3. 495.0625 - VizPix: Camera Crews on the Move
Another exciting log for the day came at 10 PM on 495.0625 MHz, a frequency that had only just started being picked up in my scanning sessions. This frequency is used by VizPix, which provides camera services for racing events.

During my scan, I heard discussions about zoom levels and tracking the action on various parts of the racecourse. It was clear that the crew was coordinating the coverage of a race, possibly adjusting cameras and preparing to broadcast the event. This frequency gave me a deeper understanding of how these camera crews communicate to ensure seamless production—another unique and practical use of the radio spectrum. In the past they had been logged active on UHF CB.

4. 509.875 - Office of Racing Integrity: A New License
The last frequency of the day was 509.875 MHz, which I found had been newly licensed by the ACMA in November 2024. This frequency appears to be used by the Office of Racing Integrity at Mowbray Racecourse.

I logged this frequency around 10 PM, and the transmissions were very active, with the team discussing which horses to check and coordinating the opening of gates for track access. This was a great find as the frequency had only just been licensed, and its activity suggested a well-coordinated team working behind the scenes at a major event.

Reflecting on a Unique Day
Overall, December 4th was an extraordinary day on the bands. It’s not every day that I get to log a brand new frequency, especially one that seemed to be used by a school staff. On top of that, I logged three other frequencies that aren't commonly active, making this a day I won't forget. From the CSE Cross Com frequency re-emerging after years of silence to the Office of Racing Integrity and VizPix frequencies, it was a mix of the old and the new, with plenty of surprises along the way.

Radio scanning has a way of rewarding patience and persistence, and days like this remind me why I’m so passionate about this hobby. It's a unique thrill to piece together the puzzle of communications, and I can’t wait to see what else the bands have in store.

Keep scanning, and who knows what you'll discover next!

UHF Horizontal Wire Loop Aerial vs. Standard Whip: A Close Call Experiment

As a radio enthusiast, I’m always curious about how different aerials perform in practical scenarios. Recently, I put my newly constructed UHF Horizontal Wire Loop Aerial (UHFHWLA) to the test against the standard Uniden whip antenna, using Close Call detection on a Uniden BC95XLT receiver. The results were both exciting and illuminating!


The Setup

For this experiment, I used:

  • Transmitting Radio: A Digitech DC-1068 set to transmit continuously on UHF CB Channel 80 (477.4125 MHz) at 0.5W.
  • Receiving Radio: A Uniden BC95XLT, locked in Close Call-only mode.
  • Aerials:
    • Standard Whip Antenna (Uniden stock).
    • UHF Horizontal Wire Loop Aerial (UHFHWLA), mounted on top, in a horizontal orientation for optimal line-of-sight reception.

The procedure was simple: I conducted five runs with each aerial, walking towards the transmitting radio until the Close Call feature captured the signal. Distances were measured for each run, and the results compared.


The Results

The difference in performance between the two aerials was striking:

  1. Standard Whip Antenna

    • Consistently captured the signal at approximately 8 metres.
    • While reliable, the whip’s performance was limited by its compact size and omnidirectional design.
  2. UHF Horizontal Wire Loop Aerial (UHFHWLA)

    • Delivered Close Call hits at distances up to 22.6 metres, with an average detection range nearly three times greater than the whip.
    • This superior performance demonstrates the loop’s higher gain, making it more effective at pulling in weaker or distant signals.

What This Means

The UHFHWLA’s performance highlights the benefits of a purpose-built aerial, especially for dedicated tasks like Close Call scanning. Its ability to capture signals at much greater distances than the whip underscores the importance of gain in aerial design.

While the standard whip is a convenient, portable solution, the UHFHWLA proves that even a simple, DIY aerial can dramatically enhance reception capabilities.


What’s Next?

This test has opened the door to further exploration. My next steps will include:

  • Testing in a Large Park: With more open space, I’ll evaluate the UHFHWLA’s performance at extended distances and see just how far it can go.
  • Exploring Directionality: The horizontal loop may have directional properties worth investigating, particularly when compared to other aerial types.
  • Comparing More Aerials: I plan to pit the UHFHWLA against a broader range of aerials, including some high-gain commercial models, to see where it truly stands.

Conclusion

This experiment demonstrated that a well-designed UHF Horizontal Wire Loop Aerial could significantly outperform a standard whip, especially in scenarios where pulling in distant signals matters. Whether you’re a scanner enthusiast or just experimenting with radio equipment, building and testing your own aerials can be a rewarding and eye-opening experience.

Stay tuned for updates as I take the UHFHWLA into more challenging environments!
