As we step into 2025, it’s a good time to reflect on the state of band monitoring in the greater Launceston area and how it has evolved over the past year. For hobbyists like me, the shift in activity and technology has reshaped what we hear on the airwaves, often leaving us with fewer active signals to tune into. Here’s my breakdown of how things stand.


TASGRN: A Quiet Network

The Tasmanian Government Radio Network (TASGRN) has been a significant disappointment for monitoring enthusiasts. For weeks now, I haven’t logged any unencrypted traffic despite scanning multiple sites regularly. While its utility for government and emergency services is undeniable, it’s a dead end for scanners due to its robust encryption protocols and the lack of use by those agencies who are not encrypted, such as TasNetworks and Hydro Tasmania.


Airband: Reliable as Ever

Thankfully, the airband remains active, providing a consistent stream of communications from pilots, air traffic controllers, and ground services. Whether monitoring commercial flights or local operations, this segment continues to be a haven for those seeking activity.


TasRail and Metro Buses: Steady Traffic

TasRail and Metro Buses are the standout active users this year. My UBCD436PT's recorder feature has been invaluable in capturing their communications. On some days, they dominate my logs entirely, offering a glimpse into the logistics and operations that keep Tasmania moving. While not always the most riveting content, they’re a reliable source of activity.


Amateur Bands: Active but “Dry”

The amateur bands, particularly 2 metres and 70 cm, still see their share of activity. However, I find the conversations often lean toward technical or niche interests that don’t hold my attention for long. For those deeply involved in amateur radio, these bands likely remain a rich resource, but they’ve become a less exciting part of my listening routine.


UHF CB: Changing Demographics

UHF CB remains active but has seen a shift. The personal users who once provided interesting chatter have largely disappeared, leaving a mix of business users and sporadic personal communications. While some users and channels still offer engaging content, they’re harder to come by than in years past.


Business Bands: A Fading Frontier

The business user side of UHF has seen a marked decline. Shared repeaters often sit silent, and some prominent users appear to have left the airwaves entirely. New users occasionally pop up, but they tend to have limited coverage or are minimally active. The migration of wide-area users to other technologies, including DMR, has further thinned the field. While DMR offers potential for monitoring, the added cost and complexity are barriers to entry for many.


The State of Scanning in 2025

So, where does this leave scanning in early 2025? Unfortunately, with fewer active users and diminished activity overall, the hobby isn’t what it once was. My UBCD436PT often sits idle for long stretches, and aside from airband, TasRail, and Metro Buses, there’s not much to hear.

This is a stark contrast to the early 2000s when I first got into scanning. Back then, the airwaves were alive with a diversity of signals and users. Today, it’s harder to justify the time and expense of scanning, especially as many traditional users transition to encrypted or alternative technologies.


Looking Ahead

While the landscape has undoubtedly changed, there’s still joy to be found in the pursuit of active signals. For those willing to adapt—whether by exploring new bands, investing in DMR capabilities, or focusing on niche areas like airband—the hobby can still offer rewards. However, for those yearning for the vibrant scanning culture of decades past, the current state of play may feel like a shadow of its former self.

Here’s to hoping 2025 brings some unexpected surprises on the airwaves. Until then, happy scanning!

Hi Paul - I live in Sydney and have been scanning since the mid-90's. It's likely area dependent, and also dependent on what you want to listen to, however I disagree there are less active signals. It's more the case that it is no longer a simple case of putting in a frequency to listen, but needing a specific knowledge of networks to get access to the signals - as you point out, a barrier to entry for many who are new to the game.

- The statewide P25 TRN in NSW (the NSW PSN) is still largely in the clear up here for emergency services, except the police, although this is slowly changing for other users. There are a large number of non-Govt/utility type users on this network now too. This can be monitored with any P25 P2 scanner.
- Large numbers of transport/business/courier/delivery/etc users who previously used a single frequency conventional repeater have moved to multi-site DMR trunked networks. Smaller single-site businesses/shopping centres/pool lifegaurds/etc have moved to simplex DMR. Both these types of systems are monitorable by most DMR capable scanners.
- There are a surprising number of various business users still using analog conversation repeaters, which is surprising considering the need for spectrum.

The best part for me, is there is no need to buy an expensive scanner anymore. While I still have a bunch of scanners, most of my monitoring is now done using SDRs. I can monitor voice and data on P25, DMR, NXDN, Tetra, etc all from the desktop using a couple of ~$50 SDR dongles.

I agree 100%, a lot of it depends on where you are located. For me and where I am, scanning as it once was is no longer enjoyable. I am jumped back to amateur radio, this has opened up some new areas for me.

I'm based in Melbourne and have numerous networks to listen to and a variety of business sites to monitor.

Furthermore I would be interested in your SDR setup for Tetra. We have the F1GP.in the next few weeks and I'd be interested to learn more.

I believe you'll find the F1GP is encrypted, so unfortunately unlikely to have success if you plan to listen in. However, OpenEar is the SDR software I use for unencrypted Tetra. You'll need an older version (v1.7.0) and an older version of SDRSharp for it to function, as the Tetra capabilities were removed from later versions due to reported licencing issues.

"I believe you'll find the F1GP is encrypted"

Is this confirmed. I only ask as we so often hear transmission over the live telecast when watching various F1 events around the world.

On a further search it seems it isn't (so apologies for that) and it appears to also be openly available via the F1TV app - how good is that!

Might be worth getting that Tetra going afterall!

I was definitely getting undecrypted Tetra last year for broadcast. I recall freqs up somewhere between 425.0Mhz and 430.0MHz
