Vertex Standard VX-241 (PMR446 Version) Replacement Batteries & Chargers

Vertex Standard VX-231

Vertex Standard VX-241 (446)  was Vertex Standard’s most entry-level license-exempt two way radio. And due to it’s price point, it sold in the millions. However, every two way radio has it’s shelf life and the VX-241 (446) has now come to an end.

But all is not lost… Read on for more information about the Vertex Standard VX-241 (446)

Need A New Radio?

Whilst both these radios have licensed siblings, VX-241(446) are low-power licence-exempt radios. So you will need to buy another license exempt radio to work with them.

Top tip: Take this golden oppurtunity to retire these radios and move to licensed radios. A licence is only £75 per 5 years for unlimited radios! In this instance, we’d recommend the Vertex / Motorola VX-261 with a Simple UK Licence.

But if you do need a radio to replace these, then the logical alternative is the Motorola XT420. However, whilst XT420 is a logical alternative and will work with the VX-241-446, it will need configuring to do so. But you can find out how to do that in the XT420 user guide (a little technical ability required).

Need A New Battery?

All of the batteries that were originally available with your radios have now also been cancelled; as have the original chargers.

Motorola has released a new charging system consisting of a single charger, a 6-position multi-charger, and a selection of batteries. This system is actually designed for the new series radios. But Motorola has also released some batteries for their historic range of radios, including the radio you have.

Therefore, you can still buy a new battery for the radio you have, but you will also need to buy a new charger. This new charger will charge the new batteries, but not the old battery.

Need A New Charger?

As explained above, all of the batteries and chargers that were originally available with your radios have been cancelled. If you need a new charger, you will also have to buy new batteries.

Vertex Standard VX-231 & VX-234 Replacement Batteries & Charger or Alternative Replacement Radio

Vertex Standard VX-231

Vertex Standard VX-231 was Vertex Standard’s most entry-level two way radio. And due to it’s price point, it sold in the millions. However, every two way radio has it’s shelf life and the VX-231 has now come to an end.

But all is not lost… Read on for more information about the Vertex Standard VX-231

Need A New Radio?

If it’s a new radio you need then the logical replacement is the Motorola VX-261. It’s practically the same radio with the same accessory connector, but the batteries and charger are different so you won’t be able to share your batteries.

Case Study: No Matter The Environment, It’s Possible!

Radiotronics have helped to fit and supply radio systems across all of the UK. We have one of the highest stock holdings in our industry, with a large catalog online we can supply most items next day that are available to find on our website. From simple small business requirements of a few radios through to multi-site trunking system, Radiotronics have the knowledge and know-how to implement any system that you require.

In order for you to better grasp some of the services we offer we have put together a collection of case studies, these showing a wide variety of the jobs that we have been asked to complete, ranging from single site systems in a theatre to an entire city wide transport communication system.

Crescent Theatre

Radiotronics were tasked with supplying two way radios for the Crescent Theatre in Birmingham, a building originally constructed in 1932, the theatre houses one of the oldest theatre companies in the city; The Crescent Theatre Company.

When the Crescent Theatre contacted us they had a number of ageing Motorola GP300 radios, these radios had been discontinued for nearly 20 years! They wanted to know a suitable like for like replacement for their trusted Motorola radios and had contacted Radiotronics for our help, alongside the radios they also wanted us to supply accessories such as earpieces and microphones for with their new radios.

The radios that we suggested were the Motorola VX-261, a new and improved version of the Vertex Standard VX-261 that was released after Motorola bought the Vertex Standard brand. The reason for recommendation by us was because of the radios robustness, this alongside its ultra-clear audio and the vast range of accessories that would be available to the users should they choose to purchase this radio. The accessories that the Crescent chose to go alongside their radios were a 6 position charging unit and covert in-ear earpieces, the earpieces allowing for quiet conversations so no disruption is made should an instruction need to be made whilst a performance is taking place.

Sheffield Hallam

A larger institution that contacted Radiotronics for radios was Sheffield Hallam University for use in their hubs building. The Hubs facility is made from a mixture of steel and concrete, one of the more challenging structures the Radiotronics had taken on fitting a two-way radio system. The building in question already had a signal extender fitted otherwise known as a repeater, this was to ensure that no matter where in the building the operator was their was full coverage.

As mentioned previously there was already an existing repeater and radio system in place but the radios where ageing and some beginning to fail. The University suggested that they wanted robust yet lightweight water-resistant two way radios, of which Radiotronics suggested that the solution for them was to take a look at the Icom IC-F2000. The reason that this radio was selected was because it is an extremely robust radio that can withstand most bumps and drops, it is also IP67 Ingres rated meaning that it can be submersed in water for a short period of time without it being at risk of damage.

An extra requirement that SHU requested was the ability to track each radio and their user, Radiotronics was able to implement this with a clock in and out system and the University has stated that it has helped to decrease the number of radios that have gone missing or become broken.

Liverpool YMCA

Liverpool YMCA is a community focused non-profit that was established in 1844, the already had two way radios that they were using within their building but they weren’t working properly, reporting both signal and audio quality issues. The building that the YMCA currently occupy is a large structure that is dense with moth steel and concrete, both of which are known to have a profound effect on the range and usability of licensed two-way radios, not to mention the low power walkie talkies that the YMCA was using.

The solution that Radiotronics chose to put forward was to supply a brand new fleet of radios to replace their existing licence free models. We choose to suggest that they should be using the high powered and hugely popular Kenwood TK-D340, this enough to effectively cover the building that the users operate in whilst still managing to provide ultra-clear audio. The 4W output power was able to give the YMCA 10x better performance than their existing radios with no issues of signal black spots.

Manchester Metrolink

Manchester Metrolink got in touch with Radiotronics to provide a solution for their transport systems during the 2018 Parklife festival that sees 80,000 people rushing to see their favourite artists. Unlike most jobs that come our way the requirement for this system was to cover the entire city of Manchester, all 44.6 square miles due to workers being stationed all across the city.

The solution for Metrolink, although it may seem a tough one, was to use a relatively new method of instant communications called Push To Talk Over Cellular. This is as straight forward as it sounds, a two-way radio with a SIM card that allows the user to broadcast over cellular networks rather than UHF or VHF frequencies. Therefore, anywhere you would have phone signal you are able to get in contact instantly to other users, even if they’re on the other side of the world! The PoC radio that we chose to offer Metrolink was the Telo TE580, the most popular cellular radio that Radiotronics have to offer.

Another benefit that was a great success for Metrolink was the ability to monitor the whereabouts of each radio from a central location, this accomplished by the use of GPS tracking. The main use for this job was to ensure that everyone was where they needed to be at the right time, but should an issue have arisen where worker safety was breached then this would have allowed for fast action due to knowing the location instantly.

Radiotronics have a sales team available to talk to should you be unsure on what system you may require. One of the best trained teams in the Industry, they can talk through with you any issues that you may be having and be able to offer you a solution. Call us today on 01425 533 533 with any questions!

The Hytera HYT TC610 And TC620

Hytera TC-610 & TC-620 Overview

Physical Attributes

The Hytera HYT TC610 and the TC620 are two of the most affordable radios on the market yet they still come with the features most users need. During the manufacturing stage many tests where performed for the both the TC610 and TC620, including a temperature test. It was put into conditions like -30oC and 60oC to find out how they cope in them extreme conditions. Both the TC610 and the TC620 are analogue radios which have 16 programmable channels which is great to say how low the price is for both of these radios. They both come with a standard Lithium battery with up to 8 hours charge in one go which is enough for the average 8 hour working day or you can purchase a larger battery which lasts up to 14 hours. As you can see here the TC610 and TC620 have an elegant design standing at 117mm tall, 54mm wide and 31mm in depth so they have a reasonably compact design. The design itself makes it perfect for any working environment. On the left side of both radios are where the programmable buttons and the PTT buttons are located. Switching over to the right side of the TC610 and the TC620 you can see the accessory connector which is also the connector to programme the radio itself but you will need a programming cable. The TC610 and TC620 also comes with a well designed belt clip… on most radios the clips just slot on to the radio and if they break by the roller you will not be able to connect a new one and you would have to buy a brand new battery. Whereas with the TC610 and TC620 the belt clip actually screws on making it stronger and better held on with the screws. This means that it is very easy to replace a belt clip even if it does break.

Hytera TC-610 TC-620 Comparison


Now onto the features, there are many features that can be programmed into the HYT TC610 and TC620. These include the time out feature, Channel scanning and VOX. The VOX feature enables you to activate the audio using your voice which creates a hands free mode and is great when you are needing to use your hands in the workplace. This can be used a lot in the security industry along with earpieces and integrated microphones, this creates a more discrete way to use your radio. The channel scanning feature allows you to receive or block more than one channel and the time out feature which comes with most radios is very important, the time out feature basically means that if you hold your PTT button for too long it will electrically time out and prevent you from communicating with your fleet for a period of time. Both the TC610 and the TC620 also comes with CTCSS and DCS which stops transmissions and digital transmissions to reach your radio. This can be useful on construction sites especially, as you wont be wanting interrupting signals blocking your channels when you’re talking about important information when on a hazardous site.


There are many accessories available with the TC610 and the TC620 and they all have their uses, furthermore all of the accessories that will be featured in this blog are compatible with both radios. Remote speakers can be very useful in a workplace environment, they prevent you from having to constantly reach down to your radio to talk which may be clipped on to your waist. The SM26M1 is a great remote speaker that is very reliable, its twisted cord is designed to prevent any wire damages that could occur with a normal straight cord. It connects straight into your accessory connector on the right side of the radio and it would then be screwed in which means it wont be easy to detach. The SM26M1 has an audio out 3.5mm jack which means you can connect a separate, compatible earpiece to it resulting in the audio transmissions you receive wont be projected through the speaker but straight into you ear. This is the only extra feature that the SM26M1 has along with the PTT button.


The second remote speaker that is pictured below, the SM13M1 (IP55) has a few more added features compared to most remote speakers. Along with the PTT button this remote speaker holds an extra button which can be programmed to hold an additional feature as well as the two that are already on the radio itself. The SM13M1 also has an audio volume control switch which can be used to either turn the volume up or turned down depending on your needs but this again means you wont have to reach down to your radio on your waist just to turn the audio volume up or down. As well as these few features it does come with a 3.5mm jack socket just like the previously spoke about SM26M1 which can connect a compatible earpiece to it. One compatible earpiece is the ES-02 (pictured below) which is a high quality and comfortable earpiece. It is a very discrete piece of equipment and it is very useful for any form of security, nightclub door supervisors and private security. This specific earpiece has a 3.5mm jack and although it can connect to the 3.5mm socket on the radio itself, it is mainly used to connect to a remote speaker.


Hytera SM13M1 IP55

Earpieces can also come with a connector which can be plugged straight into the radio with a 3.5mm and 2.5mm jack plug. The D-shape earpiece connects straight to the radio as it has an integrated microphone already part of the design. The earpiece itself is designed to attach all the way around the back of your ear meaning the chances of it falling off is slim to none. Further down the cord you will see on the photo that there is the PTT button but as well as that is a switch what controls the way your audio transmissions are sent out. It can switch from either VOX or the PTT button, this can be easily accessible just below your chin where the cord will clip onto your collar.

Hytera D-Shape Earpiece

With the TC610 and the TC620 comes many different ways to actually charge your radio, the Six Unit Hytera charger, Hytera Spider charger and the Radiotronics rack charger. The Rack harger allows you to attach and detach your own singular chargers which means you know that all of your pod chargers go in the same place with only one plug. This is essential if you struggle to find places to charge your radios or if you have them scattered around the office at different electrical plug sockets. It can also be cost effective… if you bought 4 radios and 4 singular chargers and two years later you wish to buy two more radios and chargers you don’t want to buy the 6 Unit Charger as you would be wasting the money you originally spent on buying your 4 singular chargers, but if you buy a Radiotronics rack charger you can attach all of them pods into one place without spending the money on a new Hytera 6 Unit Charger. If you are buying a new fleet of up to 6 TC610 or TC620’s and you know you’re not going to be purchasing any more in the future then the Hytera 6 Unit Charger is great to keep all of your radios in one place without having to buy any singular pod chargers. The 6 Unit Charger can be mounted on a wall which results in your desk, shelf or wherever you would keep your radios to become more spacious.

Radiotronics Rack Charger

Hytera 6 Unit Charger

If you wish to keep all of your singular chargers in one place in a more affordable way then the Spider charger is a great alternative although it isn’t as robust and reliable as the Rack charger. The spider charger does the same job as a rack charger although the pods are attached to wires rather than a metal rack.

Hytera Spider Charger


Repeaters that can come with the Hytera HYT TC610 or TC620 can come in many shapes and sizes and they all hold different qualities which you will need to know to pick the right one for you. Repeaters can be used in many workplaces like construction sites, oil rigs, on boats and in farming, its really any workplace that has a huge span and if you need to get in touch with someone who may be further than your own radios range. A repeater transmits signals further or over an obstruction that may affect your signal although the repeater would have to be on top of that obstruction for e.g. a mountain. Analogue repeaters can only amplify a signal whereas a digital repeater can reconstruct your signal to sound as clear as its original quality. Repeaters like the Hytera RD625 are available for UHF and VHF and digital and analogue radios which makes it available for everyone and it has an added mixed mode and this allows the repeater to automatically scan for analogue and digital signals. The RD625 has the ability to be mounted to a wall which can be used to protect it from damages when laid down on a desk or a shelf or if you wish to make to make your desk or table a little more spacious. It can also programme 16 channels which is perfect if you are using the HYT TC610 or TC620 as they too have 16 programmable channels.

The Best Motorola Radios For Different Work Environments

In this blog I will be comparing different radios which provide the best benefits in different working environments. Teaching, construction sites and hospitality will be some of the environments that are mentioned in this blog. If you are wanting to know which radio to use that would fit best in your work place, then this should help you in your decision making.

Schools And Colleges

In schools and colleges, the teachers are responsible to keep all the students safe as well as teaching them, meaning a reliable radio is essential to keep in touch with your colleagues for all health and safety reasons. There are many variations when it comes to two way radios so buying or renting the right one for your needs is important. Different situations can require a radio when in a school atmosphere. School trips, fire drills and lunch are all very important times to have a two-way radio to keep constant communication with your colleagues.

The first two-way radio that is useful in all these situations is the Motorola XT420. This two-way radio is licence free which means it would be more useful for small schools or colleges because they have smaller distance requirements. The XT420 is a very simple and easy to use radio with only the essential features that employees require. Channel spacing and VOX (voice activation) comes programmed with the radio which means you can include or exclude channels from the scan and you can activate the audio just by using your voice making the radio itself very easy to operate. The XT420 is affordable and licence free, so it is very cost effective if you require a large amount of the radios. Licence free radios can only reach around 800 yards which could be most useful when the students are having their lunch or break. The limited range on the licence free XT420 is one of the reasons why the price is so low compared to a licence radio where the frequency can range around a mile long.

For larger schools and colleges, a two-way radio with a longer range may be needed therefore requiring a licence. So we recommend the Motorola SL1600 compact digital radio which is more expensive but for good reason, this because it comes with Lone Worker potential whilst also having the same channel scanning and VOX that comes with the XT420. The SL1600 can reach much further in range which is around a mile long, this could be very useful when on school trips. On a school trip, teachers and the students may split up into different groups when walking around meaning constant communication is essential to keep everyone safe, the SL1600 allows that but on a much larger scale. And because the SL1600 is a compact and small radio means that practically, it is a great radio because a teacher is not going to want a huge ‘construction site’ type radio on their waist when that sort of size is not needed.


Moving on to security, more requirements and features need to be met when it comes to the radio you wish to use and many of these features are available on the Motorola DP1400 which is an analogue/digital two-way radio. 16 channels are available on the DP1400 which is a reasonable amount for a security team. Being in security, a lot of situations can arise which can be dealt with quick when using some of the features on the DP1400, like the emergency button. The way in which an emergency button works is that once pressed, a signal will go to all of your colleague’s radios, this indicating that you are in need of assistance. This is not found on other radios like the ones previously spoken about on the schools and colleges section. The DP1400 has features that improve the audio quality and the connectivity like channel scanning, VOX and an accessory connector. This allows you to connect an ear piece with an integrated microphone meaning you can hear the audio directly to your ear and speak through the attached microphone minimising movement. The accessory allows your surveillance to be as discrete as possible which ultimately protects you as the security. There is not much more that goes into the DP1400 as it is a very simple two-way radio.

Although the Motorola DP2400e is more expensive it has many more features compared to the DP1400 which are available to be programmed into the radio. In analogue mode the DP2400e has 5 tone signalling which allows you to talk to the whole fleet or to one personal members, this can be essential if confidential information needs to be passed to another colleague. The DP2400e has an accessory connector that can be used the same way as the DP1400 which is great for discretion, but the DP2400e has a compact design which means it is smaller and even more discrete compared to the DP1400. Depending on the environment you may be working in, means you need to choose the type of band your radio operates on. If working in an open environment a VHF (very high frequency) radio is suffice, whereas if you may be working in a city or a built up area then a UHF (ultra high frequency) radio is what you need to breach the structures for a good audio connection. Both the DP1400 and the DP2400e is available with both of these frequency types.

Building And Construction

On a construction site a robust and reliable two-way radio is needed in case of any accidents when working at heights or dangerous environments and the Motorola DP4400e is the radio we recommend. The DP4400e comes with 32 channels which is accessible through two zones but along with that, comes many features that are useful when working on construction sites. This includes, Bluetooth, VHF or UHF, lone worker, 5 tone signalling, emergency button, transmit interrupt and much more that are listed on our Motorola DP4400e page. Some of these features are very helpful for your personal safety when working alone or at heights or if you have an accident like the previously mentioned emergency button which becomes useful to notify your fleet quickly. The radio itself is very strong and durable and has a great grip which prevents yourself dropping the radio.

If you are wanting a smaller compact two-way radio then we recommend the Motorola VX-261. Because of its size the VX-261 can be easier to hold and practically easier to use but it comes with a lot less features compared to the DP4400e. The connection and audio quality is very similar as both radios have channel scanning and VOX but if you’re not needing all the features available on the DP4400e then choose the more affordable and simple VX-261. Probably one of the most important features available on two way radios is the lone worker and this is available on the VX-261. The lone worker feature is able to send a pre-determined signal, for example a distress call or alarm, to other radios in range, and it requires some type of interaction from the radio user after a period of radio inactivity. This is useful when working and you need to know your colleagues are with their radio. Finally, both the DP4400e and the VX-261 are only acceptable to use with a licence.


When it comes to working in a hotel, restaurant or private events you may need less features like the emergency button and more features that require quick and simple connectivity. The Motorola SL4000e brings a great amount to the table when we talk about easy communication. As you can see on the picture that it has a keyboard and a large screen which allows you to send text messages from radio to radio. This can be very useful when you are part taking in any covert, sensitive environments because it means you won’t have to talk during a convention or a workshop when a guest is appearing and presenting to a large crowd. This ultimately allows your customers or guests to have the best service without any interruptions. As well as this the SL4000e has a lot of other features that come in handy when working. Integrated Bluetooth 4.0 LE for wireless and data, up to 1000 channels, UHF, covert mode, man down and enhanced privacy are just a few of the features that are available for the sleek and slim designed SL4000e.

Although the Motorola SL1600 has already been spoken about in the ‘Teaching and Colleges’ section, it does need to be mentioned now as it is a great cost effective alternative to the SL4000e. As it is so compact and small it can come in very handy when working in a hotel or restaurant because it wont get in the way when you are working. It has a few similar qualities to the SL4000e but it doesn’t have a screen. It has channel scanning and VOX which is available on most two way radios and it does have very clear audio. As we already know it is available with the Lone worker feature that could be useful when checking everyone in your fleet is with their radio and available to talk which is good for organisation. The SL1600 is much more affordable compared to the SL4000e but again, you will be loosing the screen and keypad feature.


If you are wanting any more information about the two way radios that have been mentioned, then see the links below to each of the radios specific page. To see pages specifically on each of these environments then go to our information page and click sectors.

Motorola Solutions is the world leader in radio communications – by a very long way. There is an emerging competitor – Hytera. But as of February 2019, Motorola still holds the worldwide top spot for two way radio systems. Motorola Solutions, hereon in referred to as just Motorola, has an extensive lineup of two way radios and this guide is designed to be the ultimate guide to which is which and what does what, so to speak.

Motorola Digital Two Way Radios

Motorola Only Makes Digital Two Way Radios

Motorola has two different types of two way radios – analogue and digital. However, it’s important to note at this stage that all Motorola analogue two way radios are discontinued, with the exception of licence-free XT and TLKR series two way radios. As of 2019, there are no longer any professional grade analogue Motorola two way radios available (except new-old stock*).

* New-old stock is stock which is brand new and typically offered with warranty that’s no longer made by the manufacturer.

But What About Analogue Two Way Radios

For 6-7 decades, Motorola has made analogue radios. And Motorola sells two way radios in every country on earth. No it’s not surprising that there are millions of two way radios. And since digital two way radios have only been around for about 10 years, there are a lot more analogue two way radios out there. Motorola is aware of this. And Motorola supports old radio fleets better than any other manufacturer.

To that end, almost all of Motorola’s digital two way radios have analogue-only mode to enable the backward compatibility, to be used with older analogue-only two way radios. Most Motorola digital two way radios cannot be used in digital and analogue mode on the same channel. But you could have channel 1 as analogue and channel 2 as digital, for example. They would not be able to speak across the channels, but this facilitates a path to migration to digital.

Note: Whilst digital two way radios almost always work in analogue mode for backwards compatibility. There are a few exceptions, notably the Motorola SL4000/e and SL4010/e which only work in DMR mode.

Analogue Motorola Two Way Radios

For fairness, let’s talk about the old analogue radios before we start to talk about the digital models. There are four major analogue models that have been sold over the last 25 years and, if you take a look on eBay, these are the models you’re most likely to see for sale.

Motorola Radius GP300 “The Brick”

Discontinued: 1998

Motorola Radius GP300

The Motorola Radius GP300 was, by a long way, the best selling Motorola radio of the 90s. It had a big brother, the GP900 which was used for larger systems – and is relatively unknown when compared to the GP300. The Radius GP300 is considered a predecessor to the GP340 and they’re often confused as the same radio – they are not the same radio. The Radius GP300 was, and still is, fondly referred to as “The Brick” due to it’s 1/2 Kg weight and 140 height, 59mm width and massive 42mm depth, which is unheard of since the turn of the millennium when surface mount technology (SMT) became normal in Motorola’s two way radio manufacturing process.

The Motorola Radius GP300 came in a number of versions. The most popular was the 8-channel no-display no-keypad version. There was also a 16-channel version. And even versions of the 8 and 16 channel models with a display and keypad for private calling and other more advanced radio use. On the whole, a very good radio for it’s day.

Want One? Probably a Bad Idea. Why? Unfortunately, the Motorola Radius GP300 was discontinued in the late 90s with the last new ones being sold in the early 2000s. Whilst you can still pick them up on eBay almost all genuine accessories have been cancelled by Motorola worldwide. This radio is not a good investment, even 2nd hand. However, if you do have one and need some accessories, you can buy accessories for the Motorola Radius GP300 on our main website.

What came next? Enter the GP-Professional Series: GP340 & It’s Siblings…

Motorola GP340 (Part of the GP-Professional Series)

Discontinued: 2014 – Read More

Motorola GP340

The Motorola GP340 was the leader of the GP-Professional series. A little known fact, outside the two way radio industry, is that the Motorola GP340 was one of 5 models in the range. The entire range consisted of GP320 1 channel version, GP330 4-channel non-display version, GP340 16-channel non-display, GP360 255 channel, full display, limited-keypad version and the flagship GP380 with display, a full DTMF keypad and 255 channels. The whole lineup is called the GP-Professional Series.

So why did the GP340 become the leader of the GP-Professional Series? No one actually knows why. In theory, the GP320 with 1 channel or the GP330 with 4 channels should have been the most popular as they were in theory cheaper models with the same audio quality and build standards. The most likely reason is that dealers opted to stock the GP340 as it had every feature needed from a two way radio at the time. The GP340 covered all bases. Literally, anything a customer could need from a two way radio – the GP340 could deliver. Except of course a contact list – but this is what the GP360 and GP380 delivered.

What about the GP640? At this stage it would probably be sensible to mention the cousin of the Motorola GP340, the Motorola GP640. The Motorola GP640 looked identical to the GP340 and is often very much confused as being mistakenly dubbed the GP340’s big brother. That’s absolutely not the case. The GP640 is a radio specifically designed for trunked radio systems – specifically to the MPT1327 standard. GP640 was never designed to be used back to back (radio to radio) and, whilst it’s possible, it’s a nightmare to program in “conventional mode”. They’re not the same radio and the GP640 should be avoided unless used for a trunked system.

The direct replacement for the Motorola Gp340 is the Motorola DP4400/e – see below. However if you’re only using your radio back to back (radio to radio) and not using any of the lone worker or sell-call features, you could just use a Motorola DP1400. Read on…

Motorola CP040

Also know as: CP200 (CP140 is also a similar radio in many ways)
Discontinued: 2014 – Read More

Motorola CP040

Motorola CP040 is a slimed down radio with very basic functions. However, CP040 still maintains 4W (5W in VHF models) output power, extremely clear audio and an 8-hour “working day” battery life from the basic battery supplied with the radio.

The most observant of you would ask why Motorola would introduce this radio when they already had GP320, GP330 and GP340? Well, whether Motorola would admit this or not, historical evidence shows that the Motorola CP040 was first introduced as a counter measure to the emergence of cheaper two way radio models coming from Chinese manufacturers. The cheapest model GP Professional radio, the GP320, had a price tag of well over £200 GBP (exclusive of VAT). And there were some cheaper radios on the market for around £100 GBP each. This would, no doubt, have been affecting Motorola’s entry-level radio sales.

The Motorola CP040, also known as Motorola CP200 in the USA, was a very smart move by Motorola. The Motorola CP040 recaptured the entry level market space and Motorola CP040 became almost as good a seller as the GP340! In fact, whist there are by far more GP340s out there than any other radio  in history, the Motorola CP040 is a very close 2nd.

I have CP040’s – what should I buy? The CP040 was replaced by the Motorola DP1400, which we mention later in this article. In fact, the Motorola DP1400 is almost identical. So much so that all the accessories are interchangeable – you can buy a DP1400 and keep your existing earpieces, batteries, chargers etc. If you have a CP040 and want new radios – you should undoubtably be buying the DP1400.

Digital Motorola Two Way Radios

Enter… Motorola MOTOTRBO…

Motorola MOTOTRBO Logo

Here’s where the two way radio industry ceased to be mundane and has finally become interesting! Motorola, just before the turn of this decade introduced their DMR (digital mobile radio) based digital radio system called MOTOTRBO. MOTOTRBO is not a single product as such. MOTOTRBO is a range of products (mostly digital radios) and solutions (such as Capacity Plus, IP Site Connect and Capacity MAX). In fact, Motorola Solutions’ website has an entire section on their website dedicated to MOTOTRBO and it’s features – boasting MOTOTRBO as the world’s most feature rich, complete end-to-end, digital radio communications solution – which it is. Whilst there are some competitors who offer feature-rich systems such as Hytera’s XPT, Kenwood’s NEXEDGE and Icom’s IDAS system (and others), Motorola’s MOTOTRBO system when compared side by side offers more features and options than any other system.

The most notable features are multi-site (IP Site Connect), transmit interrupt, selective calling, advanced emergency features and GPS/Man down (only on “1” radio models). But what really sets MOTOTRBO apart is it’s ability to integrate with PC software such as TrboNET and Smart PTT, SIP-based VoIP telephone systems and multi-site quasi-trunking, also known as Capacity Plus.

GPS Note: The GPS feature is only any use when a system is connected to PC based dispatch software (such as TrboNET).

This might sound complex, but it’s really quite straightforward. The product lineup starts with the DP1400 which is the entry-tier radio. The DP4000 range are the professional tier radios with the DP2000 range are lightweight versions of the DP4000 and the DP3000 being stubby compact versions. Finally, there are the super compact and lightweight range being the SL1600, SL2600 and SL4000 radios.

Motorola DP1400 – Entry Tier Radio

View @ Motorola DP1400

Level: Entry Tier Basic Radio Systems
Introduced: 2012-2017
Price Range: £120 – £185 GBP, Per Radio (As of Feb 2019)

Motorola DP1400

The entry-level MOTOTRBO radio is the Motorola DP1400. The Motorola DP1400 is a natural step forward from the CP040 as it’s cost effective without the compromise on quality. And, as mentioned above, it shares all the CP040 accessories.

However, the Motorola DP1400 is a complex little beast as it’s the only “digital ready” Motorola MOTOTRBO radio. What does that mean? As described in our article, What’e the difference between the analogue and analogue-digital versions of the DP1400?, the DP1400 can be purchased as a “digital-ready” analogue only radio, or a digital-activated analogue and digital radio – and there’s about £50 GBP difference in price, each. Our advice has always been. If you’re intention is to simply add to your CP040 fleet, then save yourself the approx. £50 per radio and get the analogue only radios. After all, you can always upgrade to digital later. But if your intention is to slowly migrate to digital, then but the digital-activated versions straight away.

Incompatibilities: There’s also some other considerations about the DP1400, even if you buy the digital-activated model. The Motorola DP1400 is not compatible with Motorola Capacity Plus, Linked Capacity Plus (Quasi-Trunking) or Capacity MAX (Trunking). So if you’re intention is to slowly build a Capacity Plus system, this is not the radio for you. On the up side, DP1400 is compatible with IP Site Connect (via Chargeable Licence Upgrade), so can be used with basic multi-site MOTOTRBO based systems.

Ideal for most basic use: Most people will be using their existing CP040 radios back to back (radio to radio) or via a simple conventional repeater based system. The Motorola DP1400 is absolutely the ideal radio for basic level requirements. Our advice to our clients is always – only ever spend what you need to spend.

Motorola DP4000 Series

View @ DP4400e, DP4600e, DP4800e

Level: High Tier Systems
Introduced: 2012-2017 non-E Range, 2017+ E-enhanced Range
Price Range: £200 – £500 GBP Depending On Licence Features, Per Radio (As of Feb 2019)
Why buy these: Full Size Robust Two Way Radio, 5-10 Year Lifespan
Accessory Connector: DP4000 Connector

Motorola DP4000 Series

The Motorola DP4400e (previously Motorola DP4400) is Motorola’s leading radio from the MOTOTRBO range. The Motorola DP4400/e directly replaces the legendary Motorola GP340 bringing it’s GP340’s features to their new digital MOTOTRBO system. Just like the GP Professional Series, the DP4000 series is made up of multiple models – DP4400, DP4600 and DP4800.

Which are the GPS/Bluetooth/Man Down Version Models? There are also GPS/Bluetooth/Man Down models of this radio. They’re denominated by a 1 in the model. For example, DP4401 is a GPS/Bluetooth/Man Down enabled version of the DP4400. It’s important to note thatGPS/Bluetooth/Man Down features cannot be retro-fitted. If you will need GPS, Bluetooth or Man Down you must purchase an “1” version radio in the first place.

GPS Note: The GPS feature is only any use when a system is connected to PC based dispatch software (such as TrboNET).

What’s the difference between DP4400 and DP4400e, I hear you ask? DP4400e is the replacement for the DP4400, which is now cancelled by Motorola. Similarly, any DP4000, DP3000 or DP2000 series radio is now cancelled and replaced by DP4000e, DP3000e and DP2000e radios. When you’re looking to buy new radios – you should be supplied “E” models. The “E” models have some significant improvements over battery life, signal range and RFiD features. More information on the improvements on the E-range check out the “what’s new” section in this PDF document.

Motorola DP3400 & DP3600

View @ Motorola DP3400, Motorola DP3600

Status: Permanently Cancelled By Motorola
Important Note: Not DP3000 Series

Motorola DP3600

At this point it’s worth talking about the cancelled DP3400 and DP3600 radios. For many dealers, the DP3400 and it’s full keypad sibling DP3600 are seen as Motorola’s stop-gap radio. When Motorola first introduced the MOTOTRBO system, these were the first digital MOTOTRBO digital radios available. Whilst they feature many of the same features of as the DP4000 series; the DP4000 series is the official replacement for the DP3400 and DP3600, and the DP4000 series has all the features from the DP3400/DP3600 and many many more. We would always suggest a DP4000-series radio over a DP3400/DP3600 radio where possible.

DP3000 Series Note: The DP3400 and DP3600 is no longer referred to as the DP3000 series. This is because the DP3441/e and DP3661e not have inherited that title. Read more about the DP3000 series below.

Price Range: £195 – £350 GBP Depending On Licence Features, Per Radio (As of Feb 2019)
Why buy these: Smaller, Lightweight Robust Two Way Radio, 5-10 Year Lifespan
Accessory Connector: DP2000 & New DP3000 Connector

Motorola DP2000

So what are these? In a nutshell they’re almost identical to the DP4000e series above, just 1cm smaller in height. They’re the same width (ish) and exactly the same depth as they take the same batteries as the DP4000/e series. However, there is no GPS/Bluetooth/Man Down versions. They are MOTOTRBO compatible however, in order to use Capacity Plus an additional licence key (which has a price) is required. Nevertheless, use as a lightweight back to back radio, or use on a conventional repeater based system – these are ideal – and slightly cheaper than their DP4000 series big brothers.

Price Range: £275 – £395 GBP Depending On Radio & Licence Features, Per Radio (As of Feb 2019)
Why buy these: Stubby, Lightweight, Robust Two Way Radio, 5-10 Year Lifespan
Accessory Connector: DP2000 & New DP3000 Connector

Motorola DP3000e

The new Motorola DP3000 series is called “new” because there was once before a DP3000 series – the DP3400 & DP3600 we mentioned above. However, they’re now completely cancelled and these are now what’s referred to as the DP3000 series. DP3000/e series is made up of two radios. DP3441e (previously DP3441, not related to the DP3400 in any way) and the DP3661e – which is the most recent addition.

The new DP3000 series is a very special set of radios in that has almost everything built-in. There are some things that need a licence key to switch on such as Man Down, OTP (over the air programming) etc. But it’s a “1” radio – so GPS & Bluetooth are enabled by default.

The DP3441e is the non-display version of the DP3661e. Other than that they’re identical. They take the same accessory connector as theDP2400/e and DP2600/e – which means if you have DP3X01/e models and DP2X00/e models – you can share accessories between them.

New DP3000E Series Charger Notice: The new Motorola DP3000/e series does not share the DP2000 and DP4000 charger. It actually uses a charger from an older radio – the Motorola GP340 (or more specifically GP344). But the good news is that if you have a DP2000/DP4000 series charger, you can get an adapter for the new DP3000e series – which you can find on our website here or you can see the entire range of DP3XX1E chargers here.

Motorola SL1600 & SL2600 Lightweight Radios

View @ SL1600 & SL2600

Level: Mid Tier Systems
Introduced: 2014-2017 non-E Range, 2017+ E-enhanced Range
Price Range: £195 – £345 GBP Depending On Radio & Licence Features, Per Radio (As of Feb 2019)
Why buy these: Stubby, Lightweight, Robust Two Way Radio, 5-10 Year Lifespan
Accessory Connector: DP2000 & New DP3000 Connector

Motorola SL1600

These two are technically display radios. The SL1600 has an “active view display” which is a basic LED pixel based screen on the front of the radio. The SL2600 takes this a step further with a complete display and a limited set of function buttons. These are the lightest radios in the entire MOTOTRBO line up.

The SL1600 and SL2600 do have some differences, however. The SL1600 cannot be used with a Capacity Plus system, but can be used with an IP Site Connect system with a paid software upgrade. Whereas the SL2600 has IP Site Connect function built in and can connect to a Capacity Plus system with a paid software  upgrade.

Nevertheless, when used back to back (radio to radio) or on a basic repeater based system they work identically. Due to their lightweight build design, they only transmit at 3W. But their lightweight design mean they’re ideal for hospitality where a discreet communications solution is required.

Motorola SL4000/e Ultra Portable Fully Featured Radio

Price Range: £250 – £425 GBP Depending On Licence Features, Per Radio (As of Feb 2019)
Why buy these: Lightweight Fully Featured Two Way Radio, 5-10 Year Lifespan
Accessory Connector: SL4000e

Motorola SL4000e

The Motorola SL4000e (previously SL4000) is Motorola’s flagship fully featured lightweight two way radio. It supports all MOTOTRBO system features including IP Site Connect, Capacity Plus and Capacity MAX.

NOTE – UHF Digital Only: The SL4000e (and SL4000) is only available in UHF frequency and only works in DMR digital mode – the SL4000e does not work in analogue mode at all. That, to some, may be considered a drawback. However, if you’re using a UHF digital system anyway, this is not a problem. But it’s something to keep in mind when designing a system.

SL4000e is one of the lightest radios in the range and looks just like a small mobile phone. Ideal for hospitality and catering where a discreet communications radio system is essential.

Programming Motorola DP Series MOTOTRBO Digital Radios

A question we get asked all the time, literally every day, is How can I program/reprogram MOTOTRBO radios?

Motorola MOTOTRBO Software

You don’t need to if you buy new radios from Radiotronics. Here at Radiotronics, we program your new radios FREE of charge. When you buy radios from Radiotronics, we ensure they’re delivered ready to use right out the box.

However, we’re a big believer in customer choice. So if you don want to program them yourself, you’re very welcome to do that. You’ll need a specific programming cable for your radio and a piece of software, aptly called MOTOTRBO Customer Programming Software (CPS). MOTOTRBO CPS is currently at version 16.x. Everything you need to program your radios is available from Radiotronics. And whilst we can’t help you program your radios, we can pre-program them for you so that there’s only minimal things to change.

On our website you can purchase and instantly download MOTOTRBO software and a DP4000 programming cable (for DP4000/e radios) or a DP2000 series programming cable (for DP2400/e and DP3000e radios). You might also need the USB driver for your MOTOTRBO radio.

Note: MOTOTRBO v16 requires Microsoft Windows 7 or above operating system. It’s also worth noting that MOTOTRBO programming software does not work on networked computers operating in the 10.x.x.x IP range.

Base Station Two Way Radios, Power Supplies, Base Microphones & Antenna Solutions

A question that gets asked very frequently is “Do you sell base station two way radios?”. The fact is that, other than talk through radio repeaters and some HAM radios, there are no actual business type base station two way radios – certainly not on the market right now.

Question: But how come I’ve seen base station two way radios in control rooms and taxi offices? Like this one?

Base Station Two Way Radio

If you look closely, you’ll see that this is actually a mobile radio (like one you see in a taxi or lorry) sat on top of a base stand that has a built-in power supply. So when we say there are no base station two way radios, that’s not strictly true – but it does mean that you can build your own (or we can build it for you). Then you simply select a base station microphone instead of a handheld microphone.

We sometimes call this setup a “fixed mobile”, “base station mobile”, a “dispatch radio” amongst many more names. But they all mean a mobile radio with a mains power supply and microphone. Do you have some more names for base station two way radios – let us know in the comments.

So what’s needed to make a base station two way radio?

Here’s a handy list of what you need for a two way radio base station. The principles of this guide can also be applied to CB radios and Amateur (HAM) radios.

1) Mobile Vehicular Type Radio

Motorola Vehicle Type Mobile Radio

Almost all manufacturers of two way radios make a vehicle type mobile radio, as well as portables. All mobile vehicle type two way radios operate on a 12-13.8v D.C. power supply. In order to use this with a mains supply you’ll need a power supply unit (or PSU).

2) Mains to 13.8v Regulated Power Supplies

There are three different types of power supply see below.

2.1) Power Supply Unit (PSU)

Alfatronix makes a very innovative power supply called the Alfatronix AD power supply. The AD is a two way radio stand, power supply and backup battery charger. The model in the picture below is the Alfatronix AD “universal” version. But they make a specific version for the most popular Motorola, Hytera, Kenwood and Icom radios.

Alfatronix AD Universal Power Supply

The main benefit of the Alfatronix AD series power supplies is that they also have a backup battery connection where you can hook up a lead-acid battery. The battery will stay charged whilst the mains is connected. If the mains fails, the backup battery will kick in and power the radio.

2.2) Alternative – Encased Type PSU

There are many encased type power supplies. But the most notable are made by Samlex – see here on our website.

Samlex Two Way Radio PSU

The Samlex Encased style power supplies are fantastic as they position the radio around 1cm (approx. 1/2 inch) above the PSU which reduces the chance of noise from the PSU affecting the radio. You can also position a hand held microphone clip to mount a handheld microphone on the side; or you can choose a base station microphone (as shown below).

3) Selection of Microphone

You can choose one of two different types of microphone. Handheld microphones and Base station microphones. Almost all of the most popular vehicle based two way radios can be purchased without a microphone. That means you can choose the microphone you’d prefer rather than settle for the microphone you’re given.

Base Station Two Way Radio Base Microphone

Here at Radiotronics, we strongly recommend a Base Station type microphone. This is because base station microphones can help reduce fatigue, but also typically develop less faults over time and work out cheaper in the long run.

4) Antenna

The last, and most arguably most important, piece of the puzzle is the Antenna. When using a base station radio, you have two options for antenna.

Short range: If you want only short range; for example, you’re operating via a repeater or you’re operating without a repeater but your other radios are within a few hundred yards, you could consider a short rubber type antenna (shown on the base station unit above). We offer some great “right-angle” type rubber duck stubby and whip antennas from as little as £10+VAT. It’s worth noting that you’re unlikely to get much of a signal and these type of antennas only really work up to a few hundred yards at the most. But they’re ideal for repeater-based radio systems.

Medium to Long Range: If you need long range, then the only real option is a large high-gain outdoor antenna. The cost purely depends on the height and quality of antenna. We can advise further if you provide us a few details when contacting us.
