Portable Radio Monitoring in Parks - PRMIP
Portable Radio Monitoring in Parks (PRMIP) is a relaxed, exploration-focused twist on outdoor radio activities, inspired by the spirit of programs like SOTA and POTA but designed especially for listeners rather than transmitters. Instead of making contacts, PRMIP is all about getting outside, setting up your gear, and discovering what signals are out there waiting to be heard.
The concept is simple: take your radio to a public outdoor location, a park, reserve, lookout, summit, or any accessible spot, and log what you can receive across any bands you choose, whether HF, VHF, or UHF. It doesn’t matter if you’re using a handheld scanner, portable receiver, SDR, or a full field setup with external aerials. If you can hear it, it counts.
Logs are intentionally straightforward and flexible. All that’s needed is:
Date / Time
Location
Radio Used
Aerial Used
Logged Frequencies
Notes
You can record your logs however you like, handwritten notebook, spreadsheet, logging app, or printable sheet. A dedicated printable PRMIP log sheet will also be developed for those who prefer a structured format.
PRMIP isn’t a contest, award scheme, or competition. It’s about fun, curiosity, and enjoying radio in different environments. Each outing is a chance to compare propagation, equipment, locations, and antenna setups, and most importantly, to get out and about while enjoying the listening side of the hobby.

Clipboard Organiser – Portable Radio Carrying Goes “Low Profile”
But sitting there on the shelf was a Tactix Clipboard Organiser. And instantly I was transported back a few years. I used one of these many years ago for my Ultralight DXing radios, and for that role it worked brilliantly. Slim. Practical. Tough enough. I hadn’t seen them around for a while, and I’d honestly forgotten how good they were.
Then I did what any radio tragic would do. I pulled out the Pro-107 I happened to have with me. Quick test fit. And that was the moment. With the internal clipboard divider removed, I realised something interesting:
- Uniden UBC93XLT fits
- Room for accessories
- Antennas, batteries, charger, leads
- Still closes properly
That was enough justification for me. Into the trolley it went.
The beauty of this case is in what it doesn’t look like.
It’s not a Pelican case.
It’s not a bright orange toolbox.
It’s not “radio guy with gear”.
It’s a clipboard.
Builders, electricians and tradespeople carry these everywhere. That means:
It blends in.
It doesn’t scream “expensive equipment”.
It allows for more relaxed, up-close monitoring in public environments.
That low-profile advantage is underrated.
Features That Make It Ideal
- Solid Writing Surface: When closed, you’ve got a proper clipboard. Logging frequencies, jotting down callsigns, noting signal strength, all easy and stable.
- Backpack Friendly: It slides straight into a standard backpack without bulk. That’s huge for portable scanning.
Once home, it was time to customise.
First step:
Remove the internal clipboard divider.
Then I grabbed some pine lengths I’d picked up at the same time. These became my internal dividers.
Covered them in black duct tape
Installed as internal partitions
Added bubble wrap to protect radio screens
Secured everything with more black duct tape
Added a Velcro strap, to keep it safely closed.
Simple. Cheap. Effective.
No 3D printing.
No laser cutting.
No overthinking.
Just practical DIY.
The end result?
It ticks all the boxes.
Currently inside:
- RadioShack Pro-107
- Uniden UBC93XLT
- Batteries & charger
- Telescopic antenna
- Earphones
- Leads and small accessories

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.
Logged Stations – Ringarooma River (Saturday)
| Frequency (MHz) | Callsign / Description |
|---|---|
| 27.005 | 27 MHz CB |
| 27.025 | 27 MHz CB |
| 27.085 | 27 MHz CB |
| 27.205 | 27 MHz CB |
| 28.265 | 10 m Beacon (VK5WI) |
| 118.7 | TOWER-LTON |

| 165.725 | TASGRN Welbough Pass (Data) |
| 414.075 | TFS UHF Alarm (Data) |
| 476.575 | UHF CB Ch 7 |
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.)
Logged Stations – Mount Poimena (Sunday)
| Frequency (MHz) | Callsign / Description |
|---|---|
| 26.965 | 27 MHz CB |

| 461.575 | TASWater South Sister (Data) |
| 461.625 | TASWater Anson Bay (Data) |
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.

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.
