Picking a Random Radio Frequency Isn't Harmless – The Anko Walkie Talkie Recall Is a Wake-Up Call

My thoughts on this: https://trenddigest.com/au/trends/technology/kmart-and-target-recall-anko-walkie-talkies-over-radio-frequency-breach-2026-05-18

Radio Scanning, Amateur Radio and Responsible Frequency Use

Every now and then, a story comes along that reminds us why radio frequencies aren't simply a collection of numbers that you can pick at random and start transmitting on.

A recent nationwide recall of the Anko Long Range Walkie Talkies, sold through Kmart and Target in Australia, is a particularly good example of what can go wrong when radio equipment operates outside its authorised frequency allocations.

According to the recall notice published on 18 May 2026, the devices were found to operate on unauthorised radio frequencies, creating the potential to interfere with licensed radio communications. Customers were instructed to stop using the devices immediately and return them for a full refund.

For the average consumer, this might seem like a relatively minor product recall. For anyone involved in radio communications, scanning or amateur radio, however, it highlights a much bigger issue.

You cannot simply pick a frequency because it is available on your radio.

One of the biggest misconceptions surrounding two-way radios is that if a frequency can be entered into a radio, it must be suitable to use. That is simply not true.

A radio might allow you to program virtually any frequency within its technical operating range. That doesn't mean you are authorised to transmit on it.

Radio spectrum in Australia is managed by the Australian Communications and Media Authority (ACMA). Different frequency bands are allocated for different purposes, including:

• Emergency services.

• Aviation communications.

• Marine communications.

• Amateur radio.

• Commercial and industrial communications.

• Public safety networks.

• Personal and recreational radio services.

• Government and other licensed services.

These allocations exist for a reason. They allow different services to operate without unnecessarily interfering with each other.

When someone purchases an inexpensive walkie talkie, programs a random frequency and starts transmitting, they could potentially interfere with an existing service.

And that service might be considerably more important than a couple of kids chatting between the backyard and the bedroom.

The consequences can be more serious than you think

Imagine a cheap walkie talkie transmitting on a frequency allocated to another service.

Depending on the frequency, location, equipment and circumstances, the interference could affect:

• An aircraft communication.

• A marine radio transmission.

• A commercial radio network.

• An industrial control or operational communication system.

• An emergency services communication channel.

It is important not to assume that interference will necessarily happen simply because a device is operating incorrectly. However, the potential consequences are precisely why radio equipment and frequency use are regulated.

Emergency services and other critical communications rely on radio networks being available and reliable. Nobody wants an unauthorised transmission interfering with an important communication at the wrong moment.

Even if the person transmitting has absolutely no idea what they are doing, the potential impact doesn't disappear.

Cheap radios and online marketplaces

The Anko recall also raises questions about the number of inexpensive radio devices being sold to consumers.

Walkie talkies are popular for:

• Children playing around the house.

• Camping and outdoor activities.

• Family road trips.

• Sporting activities.

• General recreational use.

There is nothing wrong with wanting an inexpensive way to communicate. Imported radios, particularly inexpensive devices purchased through online marketplaces, deserve some additional scrutiny. Before purchasing a radio, consumers should consider whether it is compliant with Australian requirements and whether it is actually authorised for the intended use.

A product being advertised as a long-range walkie talkie doesn't automatically mean it is legal to operate in Australia.

A little knowledge goes a long way

For anyone purchasing or using two-way radios, there are a few simple things worth remembering.

1. Don't randomly select frequencies.

A frequency being available in your radio's programming menu doesn't mean it is available for your use.

2. Understand the service you're using.

Know which frequency band your radio operates on and what the relevant Australian regulations permit.

3. Buy compliant equipment.

Check that the radio meets Australian regulatory requirements and is suitable for the intended service.

4. Don't assume that low power means no harm.

Even a relatively low-powered transmitter can cause interference, particularly when transmitting close to another receiver or communications site.

5. If you're unsure, don't transmit.

Take the time to research the frequency allocation and applicable licensing conditions before pressing the PTT button.

Resources worth bookmarking

For Australian radio users, there are some useful official resources:

• Australian Communications and Media Authority (ACMA): https://www.acma.gov.au/

• Australian Product Recalls: https://www.productsafety.gov.au/recalls

These are good starting points for understanding frequency allocations, radio licensing and product compliance.

Final thoughts

The Anko walkie talkie recall is a good reminder that radio spectrum is a shared and regulated resource.

I have been interested in radio communications since the 1990s, and one of the things I enjoy most about the hobby is discovering what is happening across the radio spectrum.

From amateur radio and aviation through to marine, rail, commercial and emergency services communications, there is an enormous amount to discover.

But there is also a responsibility that comes with understanding and using radio equipment.

A frequency isn't just a number you can randomly select because it sounds interesting or happens to be quiet.

There could be an entire communications service operating there, with people relying on it every day.

Listen, learn, research and understand the frequencies you're working with, And if you don't know whether you're authorised to transmit, leave the PTT button alone.

Daily Carry Radio Case – November 2026

One of the things I have been working on recently is improving how I carry and protect my radio scanning equipment. While my previous case served its purpose for a while, it was becoming increasingly obvious that it wasn't really standing up to everyday use.

After a few incidents and some searching around, I've now put together a new Daily Carry Radio Case.

Why the change?

My previous case had started showing its weaknesses. On a few occasions, the clips had come open while the case was being transported, which isn't exactly ideal when you're carrying radio equipment around.

It had also developed a crack near the hinge, and I was finding that it wasn't holding everything as securely as I would have liked.

For equipment that gets carried around regularly, I wanted something a little more robust. I also wanted to keep everything together in one compact package rather than having various bits of equipment floating around in my backpack.

Finding a replacement

While browsing around recently, I came across the ToolPRO-X Metal Modular Storage System Small Plastic Organiser. It was on special for just $24, and after a quick check of the dimensions, it looked like it might be a good fit for what I needed. I decided to give this one a go.

It's a relatively compact organiser, but the layout and construction looked promising. It also offered a few features that addressed the problems I had been having with my previous case.

Reusing my custom foam insert

One of the biggest advantages of the new case is that I could reuse the custom foam insert I had previously made for my Uniden UBCD436PT. The foam was originally cut to suit the scanner and its accessories, so I was hoping it would transfer across without too much work. Fortunately, it fitted extremely well. Only a small amount of foam needed to be removed from the side to get everything sitting comfortably. This saved me having to start again and make another custom insert.

It also means the scanner remains securely positioned inside the case rather than moving around during transport.

Removable storage tubs

Another feature I particularly like is the removable plastic storage tubs.

These provide some additional flexibility and allow me to separate smaller accessories and equipment.

The tubs can also be removed individually when I only need to take a particular selection of gear with me. This is a nice bonus and makes the case a little more versatile than my previous setup.

It's always useful having somewhere to keep the smaller bits and pieces that tend to accumulate when you're involved in radio scanning!

A more robust design

The new case also has a couple of construction improvements that I was specifically looking for.

The heavy-duty latches provide a much more secure closure, while the protected hinges should help avoid the sort of damage that developed on my previous case.

Considering this case will be regularly carried around in a backpack, having something that can better handle everyday knocks and movement is important. I'm not expecting it to be indestructible, but it certainly feels like a step in the right direction.

Getting back to portable scanning

One of my goals over the coming months is to get back into doing more portable radio scanning sessions.

While I enjoy having my scanning equipment set up at home, there's something different about getting out and about, finding somewhere interesting to sit, and seeing what activity you can discover. Having a compact, organised case makes that a lot easier.

This new setup is small and neat enough to carry around in my everyday backpack without taking up too much room. It gives me a convenient way to transport my UBCD436PT and associated equipment while keeping everything protected and organised.

Final thoughts

For $24, I'm pretty happy with this little upgrade.

The ToolPRO-X organiser has given me a more practical carrying solution, allowed me to reuse my existing custom foam insert, and provided some additional flexibility with the removable storage tubs.

Most importantly, it addresses the shortcomings of my previous case.

Sometimes the best equipment upgrades aren't necessarily expensive or complicated. A little bit of repurposing and some careful planning can produce a very practical result.

I'm looking forward to putting this one through its paces over the coming months, particularly as I get back into more portable scanning.

Another small improvement to my radio scanning setup.

The Truth About Amateur Radio

Yes, it can be expensive...

Weekend Scanning - TASGRN Sites Frome Road

Over the weekend, we did a day trip to the Weld River, where it crosses Frome Road. 

While here, I did some scanning and was able to log three TASGRN sites. What I have found interesting is that compared to the previous EDACS system, the TASGRN has signal in a lot more places and from most locations, multiple sites can be received, this helps both with the coverage and also with redundancy. 

Below shows where I was (red circle) and the locations of the three sites received and site ID's decoded from the control channels.

Practical Uses for Radio Scanning: More Than Just Listening to Conversations

When people think about radio scanning, they often picture someone sitting beside a scanner, listening to police, fire or ambulance communications. While that is certainly part of the hobby, there is a lot more to radio scanning than simply listening to individual transmissions.

For me, one of the most interesting aspects of the hobby is discovering how radio communications fit into everyday life. From keeping an ear on road conditions and local incidents to understanding how organisations respond to unexpected events, scanning provides a fascinating insight into the activity happening around us.

Living in Launceston, Tasmania, I find there is always something new to discover. Even when a particular frequency seems quiet, there is often another system, service or communication method worth investigating.

Here are some practical examples of how radio scanning can be used.

1. Keeping an Ear on Family and Everyday Activities

Radio scanning can be useful for monitoring communications associated with family activities, community events and local services, provided the communications are lawfully accessible and monitoring is appropriate.

For example, public event operations may use radios to coordinate staff, manage parking, organise deliveries and respond to minor issues. Listening to event communications can reveal just how much coordination goes on behind the scenes.

You might hear staff arranging assistance for someone who needs help, directing vehicles to another entrance or coordinating the movement of equipment. These small exchanges demonstrate how radio remains a practical tool for keeping people organised.

Radio scanning should be approached responsibly, with respect for privacy and applicable laws.

2. Monitoring Road Conditions and Traffic Disruptions

Road conditions are another area where radio scanning can be particularly interesting.

Depending on what is available locally, communications associated with road maintenance, transport operations, roadside assistance and other services can provide insight into what is happening on the road network. UHF CB is espically useful to monitor in these cases.

Imagine heading out on a trip and discovering that traffic has suddenly slowed. Public traffic reports might tell you there has been a disruption, but operational communications can sometimes provide a different perspective on how workers are responding.

You may hear coordination involving:

• Road crews attending hazards or clearing debris.

• Traffic management teams arranging lane closures.

• Recovery operators coordinating vehicle removal.

• Transport staff responding to disruptions.

• Personnel arranging access for emergency or maintenance vehicles.

Not every service uses radio, and many organisations now rely on mobile data terminals, cellular networks or digital systems that cannot be monitored with a conventional scanner. Nevertheless, discovering which services still use accessible radio communications is part of the research involved in the hobby.

3. Following Accidents and Emergency Incidents

Emergency incidents are often where the operational side of radio communications becomes most apparent.

An accident may look relatively straightforward to someone passing by, but responding to it can involve several teams performing different tasks at the same time.

Where emergency communications are lawfully accessible, listening can help demonstrate how an incident develops from the initial call through to the arrival of resources and the eventual conclusion of the response.

For example, a hypothetical road accident might involve:

1. An initial report of a collision.

2. Dispatch identifying the location and sending appropriate resources.

3. Responding crews confirming their attendance.

4. Additional resources being requested if circumstances change.

5. Traffic management or recovery arrangements being coordinated.

6. Units becoming available again when their involvement ends.

The interesting part is not necessarily the incident itself. It is the coordination required to manage it.

A short radio transmission can represent a decision, an update or a request that affects several other people. Listening over time helps build an understanding of how these operations work.

The aim is to understand communications systems and operational processes, not interfere with emergency work or exploit information about people in distress.

4. Discovering the Background Activity the Public Rarely Sees

This is one of my favourite aspects of radio scanning.

The public generally sees the visible part of an operation: a truck on the road, a maintenance crew beside a worksite, an ambulance travelling through town or a security vehicle making its rounds.

What we do not always see is the coordination behind those activities.

Radio communications can reveal the routine work that takes place before, during and after something becomes visible to the public.

Consider a large public event. Attendees might see traffic controllers directing cars and security personnel walking around the venue. Behind the scenes, staff could be coordinating shift changes, reporting equipment problems, arranging supplies and responding to requests for assistance.

Likewise, a transport operation may involve routine checks, changing schedules, vehicle movements and communication between different workgroups.

None of this necessarily involves a major incident. In fact, much of the most interesting radio traffic is ordinary operational work.

It provides a glimpse into how organisations function, how decisions are communicated and how people coordinate tasks across a wider area.

5. Learning How Different Radio Systems Work

Radio scanning is not just about what you hear. It is also about understanding how the communications are delivered.

Modern radio systems can be surprisingly complex. Depending on the service, you might encounter conventional analogue channels, digital DMR networks, P25 trunked radio systems or other digital technologies.

Each system presents its own challenges and opportunities for exploration.

For example, monitoring a trunked radio system can involve identifying sites, following talkgroups and understanding how a conversation moves between radio channels. DMR monitoring can introduce concepts such as colour codes, time slots and talkgroup IDs.

Even when the actual conversation is brief, the technical information surrounding it can be valuable.

Which site is carrying the traffic? Is the signal stronger at one location than another? Does a particular talkgroup appear at certain times of day? Is the system busy during working hours but quiet overnight?

These questions turn scanning into a technical investigation rather than simply listening to a frequency.

For anyone who enjoys radio technology, there is a great deal to learn without needing to transmit a single signal.

6. Using Recording and Discovery Modes to Build a Bigger Picture

One of the most useful developments in my own scanning setup has been the ability to record radio activity and use discovery features.

A scanner does not need to be monitored constantly to be useful. Recording can help capture activity that occurs while you are working, sleeping or doing something else.

Discovery modes can also help identify previously unknown or changed system activity, depending on the scanner and system being monitored.

Over several days or weeks, recordings and logs can help answer questions such as:

• Which frequencies or talkgroups are actually active?

• What times of day are busiest?

• Are there communications that only occur occasionally?

• Has a previously quiet channel become active?

• Are there new digital signals worth investigating?

• Does activity differ between monitoring locations?

This is particularly useful when investigating systems that do not produce constant traffic.

A channel might appear completely silent during a brief listening session but reveal regular activity when monitored over a longer period.

For me, that process of collecting information, reviewing it and working out what I have discovered is a large part of the enjoyment.

7. Understanding What Scanning Cannot Tell You

It is also important to recognise the limitations of radio scanning.

Hearing a transmission does not necessarily mean you have the full story. You may only hear one side of a conversation, miss transmissions while the scanner is busy elsewhere, or lack the background information needed to understand what is happening.

There is also a difference between hearing an operational update and knowing the complete circumstances of an incident. A brief transmission may be incomplete, provisional or superseded by later information.

Radio traffic should therefore be treated as one source of technical and operational information, not as a guaranteed source of accurate breaking news.

Privacy and legality matter, too. Australian laws governing interception, monitoring, recording and disclosure of communications can be complex and depend on the circumstances. Before monitoring or sharing communications, it is worth checking the applicable rules rather than assuming that a signal being receivable makes it lawful to use or publish.

8. The Real Enjoyment Is in the Discovery

For me, radio scanning is not about listening to one particular service or waiting for something dramatic to happen.

It is about exploration.

There are systems to identify, frequencies to investigate, digital modes to understand and patterns of activity to uncover. Sometimes the most rewarding discovery is a new talkgroup. Other times it is finally understanding why a signal appears at a particular location or identifying a service that had previously gone unnoticed.

The practical side of scanning adds another dimension to the hobby. It connects radio technology with the everyday activity of the community, revealing some of the coordination and routine work that usually happens out of sight.

And the best part is that there is always something else to investigate.

Even after years in the hobby, I still have plenty to scan, search for and work out. That ongoing process of discovery is what keeps radio scanning interesting for me.

Examples of DMR Frequencies Programmed as DMR Trunk

Below are two examples of the "extra informaton" that can be received on DMR frequencies, when they are programmed as DMR trunk, not just as conventional.

If you program a DMR frequency as below, with just the mode set to digital and digital code search, you will set the Slot and Colour Code. 

If you instead program this ias a DMR trunk system, you will get the Slot and Colour Codes, plus Network ID, Site ID, Talk Group (TG) ID and even the User ID, which is the ID of that specific radio. This is all very interesting information and useful for maping out radio systems.

Uniden UBCD436PT, Trunk Discovery Mode and DMR Systems

Exploring the airwaves, identifying unknown traffic and making the most of one of my favourite scanner features.

One of the things I enjoy most about radio scanning is that there is always something new to discover. Even after years in the hobby, there are still frequencies to investigate, systems to identify and signals that make you stop and wonder who is using them.

For me, scanning has never been just about listening to a list of known frequencies. Half the fun is working out what is happening on the bands, identifying unfamiliar activity and gradually building a better picture of the radio environment around me.

This is where the Uniden UBCD436PT and its Discovery Mode come into their own, particularly when exploring digital systems such as DMR.

What is Discovery Mode?

The UBCD436PT is more than a conventional frequency scanner. Among its features is Discovery Mode, which provides a practical way to investigate radio activity without having to sit beside the scanner and manually record every interesting transmission.

There are two main options:

• Trunking Discovery: Monitors a selected trunked radio system, logging activity and recording audio associated with the channels and talkgroups it encounters.

• Conventional Discovery: Searches a specified frequency range, logging activity and recording transmissions that can be reviewed later.

Both modes can compare received activity against the scanner's programmed database. Depending on the settings, you can concentrate on new activity or log everything encountered.

For someone who enjoys exploring rather than simply monitoring a fixed selection of channels, this is a particularly useful feature. Instead of relying entirely on what is already known about a particular area, Discovery Mode gives you an opportunity to investigate what is actually being received.

Why Trunking Discovery is useful

Trunked radio systems can be challenging to investigate manually.

Rather than assigning each conversation to a permanently dedicated frequency, a trunked system dynamically allocates radio resources as users communicate. Depending on the system, conversations can move between different traffic channels, with the control channel coordinating activity.

This means that simply finding one active frequency does not necessarily tell you much about the overall system.

Trunking Discovery helps by monitoring a selected system and recording information about the activity encountered. You can then review the results, examine talkgroup IDs and listen to recorded audio where available.

This is particularly useful when you already know a trunked system exists but want to learn more about how it is being used.

It can help answer questions such as:

• Which talkgroups are active?

• How frequently are different groups communicating?

• Are there IDs that are not yet identified in my programming?

• Is there activity that I have not previously noticed?

• Are there patterns that become clearer after monitoring for several hours or days?

One short monitoring session might reveal very little. Leave the scanner running for an extended period, however, and a much more useful picture can begin to emerge.

DMR: Another layer of discovery

Digital Mobile Radio, commonly known as DMR, is widely used in commercial, industrial and other two-way radio applications.

Unlike traditional analogue FM, DMR uses digital voice and a time-division approach that provides two timeslots on a 12.5 kHz radio channel. These timeslots can support separate communications, subject to the system's configuration.

When investigating DMR, there is more to learn than simply finding a frequency.

Useful information can include:

• Frequency: Where the transmission is being received.

• Colour code: A system identifier used to help distinguish DMR systems sharing a frequency.

• Timeslot: Whether the transmission is using slot one or slot two.

• Talkgroup ID: The logical group associated with a communication.

• Radio ID: An identifier associated with an individual radio, when available.

Together, these details can help distinguish different users and understand how a system is organised.

Of course, identifying a frequency or talkgroup does not automatically tell you which business or organisation is using it. That usually takes further investigation, repeated observations and a little detective work.

Note: DMR reception on the UBCD436PT requires the appropriate DMR upgrade to be enabled. Check your particular scanner's configuration before attempting to monitor DMR traffic.

Putting the scanner to work

One of the most appealing aspects of the UBCD436PT is its ability to keep working while I get on with other things.

I can configure a Discovery session, let the scanner monitor activity and come back later to review the results. The recording and logging functions turn what might otherwise be a passing transmission into something I can investigate properly.

Rather than having to catch every transmission in real time, I can work through the results at my own pace. This is especially useful for systems where activity is intermittent. A frequency might remain quiet for an hour and then suddenly become busy. A short manual search could easily miss the interesting part.

An extended Discovery session gives me a better chance of catching those less frequent transmissions.

My usual approach is to treat discovery as an ongoing process rather than something that has to produce an immediate result. I would rather collect useful information over several days than rush to conclusions after hearing one or two transmissions.

Let the scanner collect the evidence

The real value of Discovery Mode becomes apparent when you start reviewing the results.

The scanner's saved runs allow you to revisit activity after a session has finished. Depending on your settings, you can inspect logged hits, review recorded audio and identify transmissions that deserve further investigation.

This creates a useful workflow:

1. Choose a system and site, or a conventional frequency range.

2. Configure the session, including database comparison, logging and recording options.

3. Let the scanner monitor for a suitable period.

4. Review the results and listen to recordings where necessary.

5. Identify known activity and investigate anything that remains unexplained.

6. Update your programming or notes and repeat the process.

The important part is not necessarily how many transmissions you collect. It is how much you learn from them.

A handful of useful recordings can be more valuable than hundreds of unidentified hits.

It is also worth remembering that Discovery Mode is a monitoring and investigation aid, not a guarantee that every transmission will be captured or correctly identified. Reception conditions, system configuration, signal strength and the scanner's decoding capabilities all affect the results.

Discovery Mode and long-term scanning

One of the things I have come to appreciate about running a scanner for extended periods is how much the radio environment changes throughout the day and week.

Some systems are busy during business hours and almost silent after closing time. Others become more active overnight or during particular operational periods.

A scanner that runs for long periods can reveal these patterns in a way that occasional listening sessions cannot.

This fits neatly into my own scanning routine. I enjoy monitoring different parts of the spectrum on different days, keeping an eye on VHF and UHF activity and gradually improving my understanding of what is happening locally.

Discovery Mode adds another dimension to that process. Instead of only monitoring known channels, I can use the scanner to investigate activity within systems that I am already receiving.

DMR is particularly interesting because identifying the individual frequencies, timeslots and talkgroups can provide a much better understanding of the system than simply hearing a conversation and moving on.

Over time, the information collected becomes a useful record of what I have found.

There is always something else to find

The Uniden UBCD436PT is not a new scanner, but features such as Discovery Mode continue to make it useful for the way I enjoy the hobby.

I do not need every transmission to be exciting, and I do not expect every unknown frequency to turn into something interesting. Sometimes the result is simply learning that a frequency is quiet, that a talkgroup is rarely active or that a system is not quite what I initially thought.

That is all part of the process.

For me, the appeal of radio scanning is the combination of listening, technical investigation and the satisfaction of gradually working things out. Discovery Mode supports that approach by allowing the scanner to do much of the initial collection while I concentrate on understanding the results.

Whether I am looking at a trunked system, investigating DMR activity or simply exploring the bands around Launceston, there is always another signal to investigate and another small mystery to solve.

And that is half the fun of the hobby.
