Weekend Away Playing Radios in the North East of Tasmania - 07/02/2026 - 08/02/2026

Sometimes the best radio adventures happen when you mix a change of scenery, a quiet RF environment, and a bit of flexibility. This weekend in Tasmania’s north-east ticked all those boxes, a short getaway where my wife and I both got to enjoy our own hobbies, while I managed some truly memorable radio listening.


Saturday – Ringarooma River

Saturday was spent at the Ringarooma River, with my wife happily fossicking along the riverbed. While she searched for gems, I set myself up on the river bank with a portable radio setup.

This location turned out to be gold from an RF perspective. The lack of man-made noise, combined with open terrain and distance from major infrastructure, created ideal listening conditions. What followed was one of those rare sessions where the dial just keeps delivering.

The absolute highlight was my first ever logged DX on the 27 MHz CB band from the USA. Hearing American stations roll in on CB, from a quiet Tasmanian riverbank, was something I’d hoped for but never really expected.

For a casual setup while sitting by the river, this was an exceptional haul, and the USA CB reception alone made the day a personal milestone.






Sunday – Mount Poimena (Blue Tier)

Sunday morning my wife headed off on a gem hunting tour, which gave me a perfect window to head up to Mount Poimena, the highest point on the Blue Tier at 816m ASL.

The drive and walk up are part of the experience, weaving between massive boulders and bushland before a short (about 20 minute) walk to the summit. Along the way I encountered a baby Eastern Brown Snake (often referred to politely as a “danger noodle”). It was given plenty of space and right of way, no radio contact is worth arguing with a Eastern brown snake.

At the top, the reward was full panoramic views across the Blue Tier and out toward the east coast. From a radio perspective, it was outstanding. Elevated, open, and quiet, just about perfect.

Once again, 27 MHz CB DX from the USA was flowing in strongly, and this time across a wide spread of channels. (There’s a video below showing just how strong the signals were.)

This was one of those sessions where you lose track of time — just scanning, logging, and soaking in the view.
















Overall Thoughts

It was a great weekend away. We both got to do things we genuinely enjoy, without pressure or compromise. From a radio perspective, the standout moment was logging my first USA DX on the 27 MHz CB band, something I’ve chased for a long time.

The combination of quiet RF locations, elevation, and good conditions made the north-east of Tasmania shine yet again. I’m already looking forward to a return trip, with hopes of even more DX, more memories, and maybe a little less snake-dodging next time.

Software - RomeoSierraDB

An Offline Radio Scanning Database, Built by a Radio Tragic, for Radio Tragics


As a long-time radio enthusiast, I’ve tried just about every logging solution out there, spreadsheets, online loggers, phone apps, notebooks, and half-finished projects that didn’t quite fit how I actually monitor radio.

Most of them had the same problems:
- Required an internet connection
- Were overcomplicated
- Didn’t suit VHF/UHF/SHF monitoring
- Stored data “somewhere in the cloud”

Or simply got in the way of enjoying radio, so I built RomeoSierraDB (RadioScanningDB)

What is RomeoSierraDB?
RomeoSierraDB is a local-only, offline radio monitoring logger designed for real-world monitoring across HF, VHF, UHF, and SHF. It runs entirely on your device, stores data locally, and saves everything to a single portable database file that you control. It is written in Python.

No accounts.
No cloud.
No tracking.
No nonsense.

Just logging radio.

Why Offline Matters
Radio monitoring often happens:
In remote areas
During outages
Late at night
Away from reliable internet

RomeoSierraDB works completely offline. You open your database file, log your monitoring, and RomeoSierraDB automatically saves changes back to that same file. Simple and reliable.

Who Is It For?
RadioFreakDB is ideal for:
- Scanner listeners
- VHF/UHF hobbyists
- Amateur radio operators
- Shortwave listeners
- Aircraft and marine monitors

Anyone who prefers simple, predictable tools

It’s especially suited to people who value:
- Low footprint software
- Offline reliability
- Full control over their data

Still Evolving
RomeoSierraDB is a living project. Planned and possible enhancements are being developed, but the core philosophy won’t change:

Radio first. Software second.

Final Thoughts
Radio monitoring should be enjoyable, not a chore. Logging should support the hobby, not dominate it.

RomeoSierraDB exists because I wanted a tool that respected that idea, and now I’m using it every day. If you’re a fellow radio tragic who likes things simple, offline, and under your control, RomeoSierraDB might be exactly what you’ve been looking for.

RadioShack Pro 107 iScan Review

The Radioshack Pro-107 iScan is an analog handheld trunking scanner manufactured by GRE America Inc. for RadioShack. It represents a technically capable multi-trunking receiver that uses an SD card and proprietary software to deliver flexible scanning and advanced trunk system monitoring.

Architecture & Operating Concept

  • Database-Driven Operation: The scanner stores the entire USA RadioReference frequency and trunking database on an included 2 GB SD card, which can be updated or customised via PC. Traditional manual channel programming is replaced by object-oriented memory management — objects such as talkgroups, systems, agencies and playlists make organisation highly flexible.

  • User Interface: Navigation uses media-player-style buttons and a backlit alphanumeric display capable of showing 16-character alpha tags for talkgroups, systems and user objects. There is no traditional keypad for direct frequency entry; programming and detailed list management are done on a computer.

Frequency & Receiver Performance

  • Wide Frequency Coverage: Spans key VHF and UHF segments, covering from 25 MHz up to 1300 MHz across multiple tunable ranges including air, marine, public safety and utility bands. Step sizes vary by band segment to match standard channel spacings. It does miss the 70-80MHz VHF band, which might be an issue for some people, if you scan users in that band.

  • Receiver Design: Utilises triple-conversion superheterodyne architecture for improved selectivity and stability across bands. Integrated CTCSS and DCS tone search capabilities are supported directly from the interface.

  • Scan & Search Rates: Capable of scanning up to around 75 channels per second in conventional mode and about 85 channels per second in search mode, providing fast acquisition of active signals.

Trunking & Data Capabilities

  • Multi-Trunking Support: The Pro-107 tracks analogue trunk systems including Motorola Type I/II (SmartNet/SmartZone), EDACS (wide/narrow/networked) and LTR systems directly via the SD database. Digital signalling is not decoded; only conventional analogue talkgroups and control channels are supported.

  • Talkgroup Handling: Objects represent talkgroups and systems, meaning the number of talkgroups and sites is effectively limited only by SD card capacity and database size rather than fixed memory counts.

Interfaces & Power

  • USB Connectivity: A single USB/PC interface cable provides firmware update access, data transfer and optional external power at 5 V. However, the USB interface doesn’t directly mount the SD card; an external SD reader is needed for full filesystem access.

  • Power Options: Runs on two AA cells (alkaline or Ni-MH) or external USB power; internal charging via USB is supported when rechargeable cells are fitted.

Additional Technical Features

  • Signal Stalker II: Near-field activity detection sweeps frequency ranges and locks on active signals.

  • Search & Priority: Includes multiple predefined search ranges, one user-defined search range, priority object settings and weather priority/alert support.

  • Alarms & Indicators: Programmable audible and visual alerts can be associated with objects, with support for unsquelch delays and adjustable signal threshold behaviours.

  • Memory Limits: Conventional channels and trunk talkgroups scale with SD card space; specific trunking limits (e.g., up to ~32 control channels per trunk site) are imposed by the scanner’s firmware and database structure, not by rigid scanner memory counts.


Technical Summary

The Pro-107 iScan is best categorised as a software-centric analog trunking scanner: its strength lies in database integration, broad frequency coverage and flexible object-oriented memory rather than hardware channel limits or direct manual programming. While not a digital mode scanner, it remains technically interesting for users focused on analogue trunk system monitoring and rapid database-based configuration.

Guide to Radio Scanning in Launceston Tasmania - January 2026

The radio scanning scene in Launceston Tasmania is changing, with a number of users leaving the bands for other communication methods, such as mobile phones, data terminals or using UHF CB. A new shared radio network for all government radio users (TASGRN) has been deployed and is now fully in use by a large number of government radio user, some of these used to be very active on VHF Mid Band frequencies, this has also changed the nature of what can be scanned.

Tas Fire Service / Ambulance Tasmania / Tasmanian Police / SES: All on the new TASGRN, 100% Encrypted. You can’t scan them.

VHF Airband: Very active across the state. Best frequencies:
