Pick Of The Bunch: Hytera

In the first part of this series of blog posts we spoke about various radios from Motorola Solutions including the GP340, DP1400, DP4401e, SL1600 and the XT420. You can read the full post by clicking here.

This week we take a look into Motorola’s closest competitor in Hytera. Founded in China in 1993, the company has quickly risen within the industry and has already released many iconic radios. A now global company Hytera have their fingers in many different pies, having released radios operating on UHF/VHF frequencies, Push to Talk over Cellular and PMR and DMR446 radios, this whilst also offering ATEX radios fit for use in dangerous working environments.

Hytera PD365

The first radio that we will be looking at is the Hytera PD365. One of the most popular devices from the Chinese manufacturers, the PD365 is compact yet packed full of features whilst remaining at a great price point. Ideal for use within environments where discretion is needed, the PD365 can be easily hidden out of the sight of customers especially when used with one of the many compatible accessories and microphones.

As mentioned the PD365 is small in stature which is helped in part by its antenna that is already attached to the body of the radio, something usually seen on licence free models. On the face of the PD365 there are many features that makes it stand out and help with usability.  A 3-Line monochrome display shows the user their current transmitting channel, whilst also displaying information such as signal strength and battery life. Beneath the display on the PD365 is a partial keypad, this with many buttons that all offer different purposes. Directional keys allow for navigation through menus on screen, allowing for selection of quick text messages to send to other radio users, the most common messages programmed by Radiotronics include “Job Complete” and Arrived at Location”. There is also an accept and reject call button, whilst also having three programmable buttons that allow for quick access of selected features.

One feature that you won’t find on any other two way radio is the PD365 has wireless charging capabilities. When used with the POA113 and compatible battery, simply place the PD365 within the cradle and your radio will begin charging without needing to “Slot In” as how two way radios are usually charged. These chargers can also be mounted to a rack meaning that all of your radios can be charged from a central location, you can see how one of these rack chargers are built by clicking this link to view our video.

Due to the PD365 being both analogue and digital compatible this means that it is capable of mixed mode operation. You may be wondering how this is a benefit because if you have the option for digital then why would you need analogue too? Well this is ideal should you already have existing radios within your workplace that don’t yet need replacing. Programming your new PD365 radios to have 8 analogue and 8 digital channels will allow for your new radios to communicate with both themselves and the older analogue radios, then once you have replaced your old radios with new models your 8 analogue channels can be converted to digital.

The PD365 is also available as a licence free model, the PD365LF is ideal for use in smaller working environments or for leisure activities. You can check out our product page on the main Radiotronics website by clicking here. Jacob our YouTube Guru also created a video comparing the PD365 and PD365LF, you can view the video by clicking here or checking it out below.

Hytera PD405

Following on from the PD365 we have the Hytera PD405. A radio suited to more rugged environments, the PD405 draws direct comparisons from radios such as the Motorola DP1400 and the Kenwood TK-D340. Built to IP55 protection rating the PD405 has a limited protection against dust intrusion whilst also being safeguarded against splashes of water from all angles. Environmental protection also means that the radio can be used outdoors and in a variety of weather conditions, continuing to operate seamlessly from temperatures as low as -30°C through to 50°C.

Standing at 112mm in height, 54mm in width and 28mm in heights the PD405 is compact enough to fit comfortably in the palm of the operators hand. Weighing at 270g (When BL1504 Battery Attached) the PD405 is also relatively lightweight, this allowing for the radio to be easily carried whether that be through the use of a belt clip, carry case or hand strap. As previously mentioned the PD405 has the BL1504 1500mAh Li-Ion battery as standard, this will comfortably last a standard 8 hour working shift.

The PD405 has a standard black box design where minimal error can be made when operating the radio. On the top of the radio is the antenna next to both a power/volume knob and also a channel selector knob. On the right hand side of the PD405 is a textured push to talk button above two individual programmable buttons, these can be used to allow quick access to functions such as an emergency call out to let your colleagues know there may be a safety or security breach.

Similar features are present with the Hytera PD405 that have been mentioned previously with the PD365. Mixed mode operation and quick text messaging are both a possibility with the PD405. Other features that can be made use of is Radio Check, this allows for you to check whether another radio within your fleet is available to contact. Roaming can also be used if set up, this allows for the radio to switch between sites on that are using multi-site systems, meaning that no matter how large a company you work for the radios will work with other radios on site no matter where you are. The final feature I am going to talk about is Priority Interrupt, this will allow for a radio to make an urgent transmission cutting out any ongoing conversations, this used in situations where an urgent message needs to be relayed to everyone on site in the instance for example of an evacuation or security breach.

Radiotronics are currently working on a video review of this radio, you can be alerted when this comes live by subscribing to our YouTube channel or checking back here where a link will be placed.

Hytera PD705

The PD705 is one of the more popular two way radios from Hytera, it is also available as a light version, of which we will touch on at model at the end of this section of the blog. A GPS version of this radio is also available but as we will be covering a different GPS model from Hytera we won’t be touching on this radio now, but should you wish to learn more you can check out its product page on our main website here.

Billed as a versatile professional digital two way radio by Hytera, the PD705 offers a vast variety of functionality whilst also having incredible build quality making it ideal for use in a variety of working environments. Yet another simple black box design the PD705 is similar in styling to the PD405, with both volume and channel knob on top of the radio and textured push to talk button and programmable buttons on the right hand side of the body. Although looking similar to the PD405 the PD705 has a lot more internal features that sets it apart from its Hytera counterpart.

As mentioned there are additional features that the PD705 has over other models from Hytera, the most notable being the availability of Lone Worker for use. How this works is should a radio be inactive for a pre-set period of time then an alert will be sent to the radio, think of this as an “Are you okay”. If the alert is responded to then nothing will happen but should it be missed then an alarm will be sent to other radios within the network, this allowing for fast action from colleagues should the radio operator be potentially injured. Other features that can be used but have already been mentioned previously in this blog post include the option to add an emergency button, Roaming and priority interrupt.

There are many accessories that can be used with this radio but a feature that ties in with this is the radios VOX capabilities. VOX stands for voice activation and when using a compatible accessory allows for transmissions to be made by voice alone, this ideal for industries or jobs where it may not always be possible to reach down and activate your push to talk button.

The PD705 is built to IP67 protection standards which is one of the highest ratings available to two way radios. This rating ensures that not only does the radio have a full Ingres protection against dust intrusion, but also has the ability to be fully submerged in 1 meter of water for up to 30 minutes.

Hytera PD785

The most advanced traditional two way radio that we will be mentioning from Hytera is the PD785. This radio wouldn’t look out of place next to an early 2000’s mobile phone with its styling, the PD785 has both a full colour 1.8” display and full numerical keypad. The radio itself stands at 125mm in height, 55mm in width and 37mm in depth meaning that it will also fit comfortably in the palm of the operator’s hand. Weighing in at 360g whilst the standard 2000mAh BL2008 Li-Ion battery is attached, this meaning that it wouldn’t be uncomfortable to carry this via the use of a belt clip or hand strap.

Starting off with something we’ve previously talked about in this blog the PD785 has an Ingres protection rating of IP67. This rating ensures that the radio has a full protection against dust intrusion whilst also being capable of submersion in 1 meter of water for up to 30 minutes. The PD785 is also built to MIL-STD-810 C/D/E/F/G ensuring its reliability in a variety of weather and environmental conditions including blizzards, fog, sandstorms and varying levels of shock and vibration. There is an ATEX intrinsically safe version of this radio available in the PD795Ex that we won’t be talking about today buy you can find out more about it on its product page here.

The PD785 can be upgraded to the PD785G in order to use GPS tracking. When used in collaboration with a dispatch system this will allow for each radio to be individually tracked whether it be across a large area of land or in your companies own facilities. Helping to improve both workplace efficiency and safety, there are multiple features that can benefit by the use of GPS with one being the previously mentioned Lone Worker. Similarly, to LW there is also Man Down that operates in a similar manner, but rather than monitoring the radios activity levels it monitors the orientation of the radio. Should the radio be laid on its side for a pre-set period of time then an alert will be sent to the radio, if unresponsive then GPS will allow for the base station operator to know exactly where the radio and user is to minimise risk of serious injury to the worker.

Due to both the screen and keypad the PD785 is capable of sending out full text messages between devices just as a mobile phone would, short text messages are also possible for less urgent messaging. Vibrate alert is also possible allowing for the user to be notified of incoming calls or messages, this ideal for situations or environments where discretion is key. Without rambling on too much about the PD785’s similarities to a mobile phone, the radio is capable of both group and individual calling, this allowing for private conversations to be had over the radios should they be required.

There is an endless list of possibilities when using the PD785 that would leave me writing for days, but should you wish to learn more about what this radio can do then check out our product page on the Radiotronics website by clicking here.

Hytera PNC370

The final radio that we are going to talk about in this blog post is the latest push to talk over cellular radio from Hytera the PNC370. A technology that has taken the communications market by storm in 2019, PoC allows for instant communications no matter the distance via the use of cellular signalling. By using 3G, 4G and even WiFi this means that there really are no limitations to how far your communications can go, this ideal for use in working sectors such as transportation and public services where workers aren’t confined to one area of land in order to perform their duties.

Standing at 121mm in height, 55.5mm in width and 24mm in depth the PNC370 is a relatively compact radio, this whilst also weighing in at 185g with the standard 3100mAh Li-Ion battery being attached. There are two carrying solutions available in both the BC08 belt clip and RO01 wrist strap meaning that due to its weight no matter how it is being carried it is comfortable and will cause no strain to the operator.

Due to operating using cellular networks GPS tracking comes as standard with the PNC370. When used in collaboration with a dispatch system back at base the location of each radio can be tracked, this allowing for both improved safety and efficiency when working. Another positive of using GPS tracking especially in the transportation industry is that it allows for accurate arrival times, allowing for the end consumer to be prepared for whatever shipment may be arriving.

The hardware inside the PNC370 allows for the radio to run smoothly even after extended periods of use. Some of the specifications that the radio has included a 1.1GHz Quad Core processor, 512MB of RAM, 4GB of Internal memory all whilst running on an Android 5.1 operating system. On to the aesthetic look of the PNC370 the face of the radio is made up of multiple features. A 2” full colour display notifies the user of information such as time, battery life, cellular coverage and allows for the user to easily navigate through menus to access functions and make both individual and group calls. Beneath the monitor is both an options, back, home screen and navigational buttons. Whilst even further down are an accept and reject call and two programmable buttons, allowing for important functions to be accessed at the click of a button.

The PNC370 is the most simple of the Hytera PoC radios. If you would like to learn about the more advanced Hytera PNC550 or PDC760 then you can access them on our website by clicking either of the product names in this paragraph.

Hytera PD365 and PD365LF Full Review

Hytera continue to progress in their technology to make their customers life easier when using two way radios. In 2015 the Hytera PD365 and the PD365LF (licence free) were released and since then they have still been incredibly popular on the market. It is mostly popular for their size and accessibility and how easy they are to use with many different keys and options.

Hytera PD365/LF

Both the PD365 and the PD365LF come as analogue and digital. The LF is the licence exempt version meaning when working in small environments like schools, nurseries or small warehouses the PD365LF would be more suitable. The LF transmits PMR446 and DMR446 frequencies which is for licence free radios only. The PD365 comes with UHF and VHF frequencies. UHF best suits areas with obstructions but still works the same in open spaces and VHF is better suited to open spaces with minimal obstructions. This radio is incredibly versatile and can be used in all work environments except when working around gas, oil or nuclear materials. An ATEX/ intrinsically safe radio will be needed when working on oil rigs, in power stations or in mines.

Physical Attributes

As you can see by the picture the Hytera PD365/LF is not the usual looking two way radio with a large body and long antenna. Designed to be compact and comfortable in the user’s hand it only stands at 107mm tall, 55mm wide, 23mm in depth and only weighing 160g. The small antenna on top is designed this way so it does not get in the way of the user and allows it to be kept safe in the user’s pocket. The antenna guarantees that transmissions will still be sent long distances reaching up to 1 mile for the PD365 and around 500 yards for the licence free version. Moving to the left side of the radio the PTT button and one of four programmable buttons are located. On the left side is where the accessory connector and the charging port is. And on the front there are many keys which can look complicated but it is quite the opposite. First lets look at the 3 remaining programmable buttons which are the P1, P2 and P3 keys. These can hold a single feature each which can be used in many different ways. Above these are the answer and end call keys and the end call key is also used to turn the radio on and off when held down for around 3 seconds. In the middle are the navigation keys which allow the user to go through the menu, different channels and different features on the radio which will be listed on the LED screen. Finally, the two keys at the top left and right are the enter and return keys. When the user is navigating through their menu the left key can be used to click through different options and the right key can be used to return back to the previous option on the menu. At the top there is also the speaker which will allow the user to hear any transmissions being received. And the microphone is located just underneath which will pick up the user’s voice once the PTT button is held down or if the user makes a call. These physical attributes are the same for both the PD365 and the licence free version.


There is only one major difference between the PD365 and the LF which is is the range of communication. As mentioned before the LF will reach around 500 yards making it much more suitable for small workplaces and the original is better for large spaced environments. The PD365 will have greater audio quality as it is licenced but the audio quality for the LF is one of the best in its class. Many features can be programmed into both the PD365 and the LF and these include private call, text messages 256 channels for the PD365 and 16 for the PD365LF. At Radiotronics we only programme the amount of channels suited to the licence purchased from Ofcom. Obviously the licence free PD365 will not need a licence which is why this only allows for 16 channels to be used. VOX is available for both radios which allows the user to activate their transmissions using their voice without pressing the PTT button. This means that the user can simply talk and the radio in use will automatically pick it up and transmit the information to the channel they’re on. Pre-programmed messages can be used and the PD365/LF have 10 available slots to send each containing messages with up to 64 characters each. This can be incredibly useful for communication in covert environments or for organisation in the workplace. An emergency alarm is also available to be programmed which allows the user to press the programmed button which will send an alarm to everyone in the fleet to notify them of an emergency. This can be used to evacuate the premisis or to avoid a certain area or incident. These are all available for the PD365 and the LF but there are a few more that are available on just the PD365 as it is licenced. These are remote monitor decode, enable and disable decode and transmit interrupt. Transmit interrupt allows the user to interrupt any on going transmissions on their channel to notify the whole fleet of an emergency.


The Hytera PD365 and PD365LF comes with a few possible ways to charge the radio and they are either directly into the radio with a micro USB cable or with the optional paid extra wireless charger. The micro USB cable will charge the battery and gives the radio power to last around 12 hours but it has nothing to stand in like a pod charger.

Hytera Micro USB Charger

The wireless charger is what it says on the tin. It charges the user’s radio with no wires included and is a great way to keep the fleet organised while charging and all kept together safely. It is also another way Hytera have shown off their new technology and made themselves look much more advanced and creative then ever before.

Hytera Wireless Charger

The final way of charging the radios is suited best for larger fleets and this is a 6 way charger. This has 6 cables all routed and converted into one cable which plugs into one power supply. This allows the user to charge up to 6 radios at a time with them all being together and organised. The 6 way is also more efficient as it only plugs into one power source whereas 6 single cable would need 6 separate plugs which can create separation when charging and storing the fleet.

Hytera 6 Way Charger


There are limited accessories for the PD365 and PD365LF there is only one earpiece available specifically for these radios and that is the EHS16 earpiece which is a receive and reply earpiece. It fits comfortably onto the ear and allows the user to hear any transmissions directly to their ear. The EHS16 also comes with an integrated mic and PTT which means transmissions can be sent without the use of the radio itself. This accessory can be used in most work environments and is great to use when working in loud or quiet places. In covert conditions, the earpiece will allow the user to hear transmissions while no one else in the room can hear them. In loud environments the EHS16 will allow the user to hear transmissions over the noises in the background as the user may not be able to hear them through the radio’s speaker. Clearly the EHS16 can be used in any condition.

Pick Of The Bunch: Motorola Solutions

Not quite sure what you’re looking for in a two way radio system? In this series of blog posts we’ve decided to break down your best choices from a variety of brands, even including a few case studies too to ensure you know exactly what you’re getting with each radio.

The two way radio industry has been dominated by Motorola for quite a few decades, this the reason why they are the focus of today’s blog, but as time progresses more and more competitors are entering the market. Hytera have been hot on the heels of the American corporation but companies such as Kenwood, Entel and Icom are commonly known names in many industries across the United Kingdom. A technology that has snowballed into consideration over the past few years is Push to Talk Over Cellular, although big companies are now throwing their hat into the ring, a company that Radiotronics highly recommend for PoC is Telo who we will be talking about at a later date.

Motorola was initially founded in 1928 as Galvin Manufacturing Company, at this time the company was producing battery eliminators, but in 1930 the company sold its first car radio under the product name of Motorola. Moving on to more recent times, Motorola has been hugely dominant in the two way radio industry taking up a large portion of the marketplace sales for multiple decades.

Motorola GP340

The GP340 is the first two way radio that we will be talking about, although many radios were released before this model, the GP340 is an Icon within the industry as it is still the best selling two way radio ever. Ideal for a variety of different environments, the GP340 was affordable yet feature rich meaning that you got more than your money’s worth when purchasing.

Although now a discontinued radio, Radiotronics has existing stock of this product so should you be looking to purchase the old faithful then we are the only company in the country that still supplies them. Available for both UHF and VHF frequencies, the GP340 is analogue meaning that it can only be used in an analogue system, but it is capable of operating with digital models should they have analogue channels programmed into them. For it’s time the GP340 has exceptional sound quality, X-Pand™ Voice Compression ensured that any communications are crisp and clear even in the noisiest of working environments, low level expansion also allows further improvements by reducing noises that can often be heard in pauses of conversation.

Emergency features were aplenty on the GP340 with emergency signalling a possibility, this allows for a pre-defined alert to be sent to a specific person or group of people should the user be in trouble, this done by simply pressing the programmable emergency button on the radios body. Lone Worker is a feature that is present on almost all new radios but was something that really made the GP340 stand out, this feature monitors the radios activity levels, should the radio not be used for a pre-programmed amount of time then an alert will sound on the users radio, if the operator is unresponsive an alarm will be sent to other radios within the network making them aware that a member of staff is potentially unsafe.

Some of the basic need-to-know facts about the Motorola GP340 is that it is an average sized “black box” two way radio. The GP340 stands at 137mm in height, 57.5mm in width and 37.5mm in depth with the standard battery attached, the battery that comes as standard with the radio is 1400mAh Li-Ion and when connected brings the radios total weight to 420g. The supplied battery allows for up to 11 hours usage based on a 05 05 90 duty cycle.

The Motorola GP340 has 16 channels ensuring that it is more than sufficient for small to medium sized businesses, the radio is available on both UHF and VHF frequencies meaning that it is ideal for use in both built up areas and wide open spaces. Channel scanning allows for the user to quickly skip through channels in search of an ongoing broadcast, whilst standard encryption ensures that any communications sent and received are safe from eavesdropping.

Motorola DP1400

Although not the direct replacement for the Motorola GP340, the DP1400 almost certainly took the prize of most popular current two way radio that is available on the market. Yet another “black box” design from the market leaders, but what it lacks in aesthetics the two-way radio makes up for in features. The DP1400 is simple and affordable, a common theme with Motorola radios, but its ability to perform on both analogue and digital frequencies makes it perfect should you be looking at a system migration.

Starting with the basics of the radio, the DP1400 stands at 127.7 in height and 61.5 in width, depending on the battery that is attached to the radio the depth and weight will change. Should the 1400NiMH battery be attached then the radio has a depth of 42mm and a weight of 406g, the 1600mAh Li-Ion slim battery is slightly smaller in depth being 39mm and much lighter weighing in at 341g, finally the high capacity 2200mAh Li-Ion battery is 44mm in depth but only 346g in weight.

As previously mentioned the DP1400 can operate using both analogue and digital, although digital is a paid upgrade, having a radio with both analogue and digital frequencies will allow for the DP1400 to be used as a transitional radio should you be moving from an analogue only system to a digital one. The Motorola DP1400 can be programmed with 8 analogue channels to match the old radios and 8 digital channels, this meaning should you not have the funds to buy a full set of radios for your business you can continue to use the old ones alongside your new radios until you have a full set, at this point you will be able to program your transition radios to be all digital channels. Alongside being both analogue and digital capable the DP1400 can operate using both UHF and VHF frequencies, this meaning that it would be ideal for use in both built-up and open areas of land.

There are many features that the Motorola DP1400 holds. One of the most basic and seen on almost all two way radios is the emergency button, when pressed this will send out a distress signal to all other radios within the network alerting them that you may be in trouble, this can be pre-programmed when purchasing a new set of radios. Channel scanning allows for the radio to quickly run through channels to check for any ongoing transmissions, whilst a channel monitor function allows for a single channel to be listened to even when sending messages on a second channel, this is often used as a channel to alert workers of any issues or safety concerns quickly. The last safety feature that I will mention is Lone Worker, this exactly the same as the one found on the Motorola GP340, whereby should a radio be inactive for a pre-set period of time an alert will be sent to other radios within the system.

The Motorola DP1400 also has accessibility features that help improve the user experience with the radio. An Integrated voice allows for channel number announcements when the channel is changed by using the knob on top of the radio, this ideal should you be working in lowly lit environments where you may not be able to see the markings around the knob. Busy channel lockout ensures that only one person can transmit at a time, this helps as it allows for you to broadcast without being interrupted, the radios would be effectively useless should every time you go to transmit your message is merged in with another operator’s transmission.

A final note on the DP1400 is its ruggedness. Built to IP54 rating this ensures that the radio has Ingres protection from dust intrusion whilst also being safeguarded against splashes of water, this ideal should you be wanting to use it in an outdoor environment where there is a risk of rain or a construction environment where dust presence is common.

Motorola DP4401e

The Motorola DP4401e is one of the DP1400’s big brothers. Although not identical to the latter, take away the Motorola logo and you would still be able to tell that the DP4401e is a Motorola radio. A durable look and feel, the DP4401e was designed for use in harsher work environments where the radio equipment used may be subject to accidental drops or coming into contact with excess dust or splashes of water.

Built to IP57 Ingres Protection this means that the DP4401e has the same dust intrusion protection as the DP1400, but the main difference being that the DP4401e is capable of being submerged in 1 meter of water for up to 30 minutes. Military specification (MIL-STD-810 C/D/E/F/G) ensures that the radio can be used in a variety of environmental conditions whether this be storms or high humidity, the DP4401e can continue to operate in temperatures as low as -30°C through to 50°C.

Due to the DP4401e being designed towards environments where worker safety is crucial, the radio has a variety of different features that can both assist in safety and efficiency of the workplace. Alongside the previously mentioned “Lone Worker” there is also a man down function, acting in a similar manner, should the radio be laid on its side for a pre-set period of time then an alert will be sent to the said radio, if unresponsive then an alarm will be sent to a base station or other radios within the network to alert them of a potential issue. Man down and lone worker can both be used in collaboration with GPS location tracking, this would allow for the user in need of help to be found quickly to minimise the risk of serious injury or damage. GPS is an optional extra purchase and would also require the use of a dispatch solution for tracking of radio and user location.

Motorola claim that the DP4401e has best-in-class audio and having used one I can confirm that the sound quality is crystal clear. A loud front-facing speaker and intelligent audio automatically adjusts the volume of the radio to ensure that no transmissions are missed, should you be working in a loud environment then the DP4401e would be perfect. Should you also not be in a situation where you are able to talk to a co-worker, pre-programmed text messages can be sent to notify others of your status, some examples that have previously been used by customers of Radiotronics include “Arrived at Location” or “Job Complete”.

Unlike the 2 previously mentioned radios in the blog the DP4401e also has Bluetooth capabilities. When activated this will allow for the user to make use of the many Bluetooth accessories that Motorola make for this radio, although not something that everyone will want or require, this feature is handy as it allows for the user’s movement to not be limited by wires that may get in the way.

A final mention on the DP4401e is its ability to perform over multiple sites and with thousands of devices without the need to add extra frequencies. Using IP Site Connect and Capacity Plus the internet is used to extend voice and data capabilities via MOTOTRBO. Linking up to 15 different working sites this can spread across multiple geographical locations it is almost definitely too complicated for me to explain in a simple paragraph, if you would like to learn more about this then you can check out our dedicated page on our main website by clicking here.

Motorola SL1600

The SL1600 is a relatively new device from Motorola having only been released in the past couple of years*. This radio has a sleek design, quite different from the previously mentioned models in this blog and is ideal for use within hospitality environments. Small in stature the SL1600 is easily concealed weighing 169g and standing at just 126mm in height, 55mm in width and 22mm in depth, this meaning it easily fits in the palm of the average hand.

Available for both UHF and VHF frequencies means that whether being used inside a building or covering estate grounds the SL1600 can be modified to suit your surroundings. With the radio being digital this provides exceptional voice and audio quality, ensuring that transmissions sent and received are heard clearly first time round so that no miscommunications are made.

The SL1600 has an active view display using hidden LED lighting to show current channel, radio and volume information. This screen is easily visible in both light and dark conditions, ensuring that user knows exactly what channel they are transmitting over. Should looking at the screen whilst working not be an option, a voice announcement can be programmed into the radio to notify the user by ear when channel has been changed.

Unlike most two way radios the SL1600 doesn’t require a pod in order to charge, MicroUSB connectivity allows for the radio to be both charged and programmed simply by plugging a cable directly into the radio. Finally the Motorola SL1600 is famous for its simple operation with a standalone power button, channel toggle switch on top of the radio, volume control buttons and push to talk button on the left hand side, these adding together to make the operation fairly easy and allowing for one handed radio operation.

*Accurate as of 2019

Motorola XT420

The final radio that we will be talking about in this blog is the licence free XT420. Ideal should you be looking for an affordable radio to operate over short distances, the XT420 uses PMR446 frequencies and 219 selectable privacy codes to help ensure a clear signal. A powerful 1500mE speaker also helps to ensure high quality audio, this minimalizing distracting feedback when operating in noisier environments.

With two programmable buttons this allows for commonly used features to be easily accessed. The XT420 is also VOX capable, this is a feature that is required to be programmed into the radio, once activated VOX voice activation allows you to communicate without having to press the push to talk button located on the side of the radio. The Motorola XT420 also has a Tri-Coloured LED which updates the user on radio features and current status, allowing the user to check at a glance for any incoming messages or alerts.

The Motorola XT420 isn’t recommended should you be working over large distances or with heavy building coverage. The radio has an Ingres Protection rating of IP54 meaning that although it has a limited Ingres against dust and protection against splashes of water, using the XT420 in environments where it may be subject to adverse weather conditions isn’t recommended.

One Of The Most Popular Radios On The Market

Motorola GP340

One of the most popular radios of all time was the Motorola GP340 but after such a successful radio what could Motorola do next? Well they released a new radio, which has changed the market since, and that is the Motorola DP1400.

Physical Attributes

Motorola CP040

The Motorola DP1400 was made to replace the CP040 but also replaced the famous GP340 in popularity. It is an analogue/digital hybrid two-way radio, although as standard comes simply as analogue with digital being a paid upgrade, the DP1400 available for both VHF or UHF frequencies. Standing at 127mm tall, 61mm wide and 42mm in depth and weighing 240g the DP1400 is robust and reliable and is built to be long lasting in any type of environment. One of the main reasons people love this radio so much is because of its affordability while still having all the features needed in a standard radio. Motorola are great at doing this with a lot of their radios being at a great price point and the DP1400 is an example of this.

Moving on to features the DP1400 has quite a few important features that can be used in any work environment. 16 channels are available to be programmed into the user’s radio and channel scanning will allow them to scan through all the channels in use to hear any incoming transmissions. VOX is also available which allows the user to send transmissions without the need to press the PTT button, and instead just simply talk, this is a pre-programmable feature and accessories can be bought to support this function. Compatible accessories, earpieces and headsets, allows the user to use VOX while using these accessories. It can create a hands free mode which means any work can be done without having to hold the radio in their hand. Lone worker can also be programmed into the DP1400 which works perfectly to keep anyone working alone safe. If the radio is inactive for a pre-set amount of time, then an alarm will be sent to the worker’s radio. If the alarm is answered then the supervisor and/or fleet will know that the lone worker is safe and not injured, if the alarm isn’t answered then a separate alarm will be sent to the fleet which will notify them that the worker could be injured or unconscious and action can be made to help that person. Transmit interrupt is available for the DP1400 which allows a supervisor to interrupt any ongoing transmissions to deliver important and critical information when needed. This means that if any incident occurs that could put others in risk, they can be notified straight away rather than the supervisor waiting for a conversation to end to notify the fleet. Another way to notify the fleet of an emergency or incident is by using the programmable emergency button, once pressed this will instantly notify the fleet with an alarm that signals of an emergency taking place. This can be used to evacuate the workplace or to take caution of an area and situation.


When you purchase a Motorola DP1400 a charger is not included but the user can choose from a few different chargers. The charger will depend solely on the size of the user’s fleet. A single pod charger is available for those who only wish to purchase maybe only two DP1400’s which will charge just one radio at a time. Buying two pod chargers will allow the user to charge both of their radios.

For larger fleets a larger charger will be needed. If a user wishes to buy 6 radios, then a 6-unit charger will be the better alternative to power their radios. This keeps the fleet together while charging the radios from one power supply. This is much better for organisation when storing the radios in a safe place.

Motorola 6 Unit Charger

There are many ways to charge and power a DP1400 but the final option I’m going to talk about is our very own Universal Rack Charger. This combines 6 existing pod chargers to one power supply and rack which is great to keep all of them together. Each pod charger has its own wire and charging plug but the rack charger converts them all to one. It can be easily installed in the workplace and it is robust and designed to last an incredibly long time.

Many accessories are available for the Motorola DP1400 and they can all be used in different work environments. First I’m going to talk about the PMMN4013A remote speaker microphone which plugs directly into a DP1400. It allows the user to send transmissions to their fleet using the microphone rather than the one on their radio. This means the radio in use can stay clipped to the user’s belt and the microphone can be clipped to their shirt or jacket creating easy access for communication. The PMMN4013A also has an additional 3.5mm jack connector which can connect compatible earpieces like the PMLN7560 to it.

Earpieces like this one is great for discretion when working in covert environments. It allows the user to hear any transmissions directly to their ear which prevents anyone around hearing the information being received. As mentioned this is great for covert, sensitive environments but it also works amazingly well for loud and noisy environments. A door supervisor at a nightclub or bar will be in the middle of all the noise but with the covert earpiece that person will be able to hear any transmissions for instructions or direction. Using the RSM and the earpiece together with VOX ultimately creates a hands free way of communication.

Motorola Covert Earpiece

Although I have already mentioned a work environment I want to quickly list and talk about the variety of work places the DP1400 can be used. This may give perspective of how popular this radio actually is. It can be used in all sectors of work except when working around gas and oil. When working in them environments an ATEX radio is needed for health and safety reasons and we would recommend the DP4401 Ex. But back to the DP1400 it can be used on farms, in schools, in warehouses, on construction sites, nightclubs/bars, in catering of all types and security. From hotels to wind farms the DP1400 can be used anywhere. If you need an affordable, easy and organised way of communication in your workplace then the DP1400 is for you. It is incredibly robust and will ensure the user great organisation, safety and work efficiency if the features and the radio is used correctly.
