Kenwood, Hytera and Motorola are some of the largest companies to provide us with two-way radios and each of them have their own popular DMR radio. Kenwood’s most popular DMR radio is the TK-D240/340. Hytera has the PD405 and Motorola has the famous DP1400.
First lets start with the Kenwood TK-D240/340. They are both exactly the same in every way except the 240 is VHF and the 340 is UHF. All the features and physical attributes are identical. Both radios stand at 122mm tall, 54mm wide and 34mm in depth meaning it is designed to fit in the user’s hand comfortably. It is thinner than most radios which makes reaching around the radio to other buttons much easier. The TK-D’s only weigh 285g which is pretty light for a taller radio. Looking at features the user has many to choose from. 32 channels comes as standard with both radios through two zones and channel scanning can be used to scan through all the channels in use to hear the next incoming transmission. Rating IP55, the TK-D’s can withstand dust and has limited protection against water. Lone worker is also available to be programmed which allows the user to work safely when working alone. Should the user’s radio be inactive for a pre-set period of time an alarm will sound. If the user does not respond to the alarm in a set time then an alert will go out to their fleet, notifying them that they are potentially injured or unsafe while working alone. This can work great for many different work environments like a warehouse or as security. Transmit interrupt is available which allows the user to interrupt any on going transmissions in an emergency to notify the fleet. This works well when the channels are busy and there is an emergency. This feature is usually programmed into the supervisors radio as only one or two users may need this feature. CTCSS and DCS prevents unwanted transmissions and digital transmissions from reaching your TK-D340, this can be useful on a construction site where you may have to listen closely to instructions for safety. As well as this, busy channel lock out will also block some transmissions out when the frequency appears or is in use. The user’s receiver could could be receiving another signal but it is muted due to squelch settings. The TK-D240/340 has the time out feature which will electronically prevent the PTT button from being used if it is held down for a long period of time. This stops any damages to the user’s radio and it means that all commands and transmissions should be short and simple.` If the user wishes to talk to someone personally then direct mode is available. This will allow someone to talk directly to a member of their fleet personally to discuss anything private or sensitive. There are many other features available and a great digital feature is the fact that the TK-D’s enables the user to have to separate conversations on the same channel frequency. As we can see the TK-D340 and TK-D240 have many great features available and it is incredibly clever. It is cost effective and can be used in many different ways.
The next radio we will be looking at is one of Hytera’s most favoured radios, the PD405. This radio is much more cost effective than most entry level DMR radios but does it match and keep up with it’s competitors in productivity? The Hytera PD405 stands at 112mm tall, 54mm wide and 28mm so it is a similar in size to the Kenwood TK-D240/340. Weighing 240g the PD405 is lighter than the famous Kenwood radio making it even more comfortable in hand. UHF and VHF is available with this radio meaning it can be used in any work place in any environment. There are many features available with the PD405 that can be used to create more efficient work, better communication and greater safety in the workplace. This radio comes with 16 channels that can be used as analogue, digital or a mix of the two (hybrid). DMR signalling is present which betters the quality of the audio and the connectivity between radios. VOX is available which allows the user to activate transmissions without the need to press the PTT button. Once the user begins to talk the radio will automatically begin to send a transmission. This works amazingly well with compatible earpieces and remote speaker microphones. Lone worker is available meaning this radio can be used for user’s working alone. An emergency button can be programmed into one of the programmable buttons. Once this is pressed an alarm will be sent to the whole fleet which will notify them all of an emergency. This feature can be used as an alarm to evacuate the premises or to keep employees away from a certain area or situation. Roaming is available which allows the user to switch between sites on multi-site conventional systems giving flexible communication between the fleet. There are not many other features available for this radio. The important features are included but it is not quite as accessible as the TK-D240/340 but the PD405 is much more affordable.
The final radio that I’m going to talk about is one of the most famous radios released and has been at the top of the market since it was released. Motorola’s DP1400. Coming with UHF or VHF this radio can be used in any environment from farming in open fields to security in a city. This radio is affordable and it comes with so many features to make work life even more easier and safe. It stands at 127mm tall, 61mm wide and 42mm in depth making it he largest out of three radios I’ve spoken about. But imagine it is just holding in so much potential! A lot goes into this radio and although it is that little bit larger, it does fit comfortably in hand. The DP1400 can also come in different colours when buying from Radiotronics for an additional cost. Rating IP54 the DP1400 can withstand dust and it has limited protection against water. 16 channels comes as standard and channel scanning can be implemented to allow the user to hear the next incoming transmission from any channel. CTCSS and DCS is present which will block out any unwanted analogue or digital transmissions from reaching the user’s radio. Lone worker can be programmed for those who work alone. VOX is available for anyone wishing to communicate easily and quickly without the need to use their hands. Transmit interrupt is available for emergency announcements to the whole fleet. So the DP1400 has the main features that the TK-D240/340 and the PD405 have but there are many other features like busy channel lock out, digital private line, talkaround, audio gain control available. This radio is more advanced than the others which is why it is so popular in many different countries around the world. It is in the middle for price with these three radios but as it has so many features it could easily have been the most expensive. The voice quality and connectivity is very clear and it does not sound robotic like at all. The connectivity is also great because of the DMR signalling. The DP1400 is easy to use in many different ways in many different work environments and can make a huge difference in any work place. Motorola know how to get the public’s appreciation with a great radio that is also affordable. Many accessories are available with this radio including remote speaker microphones, headsets, earpieces and carry cases whereas with the PD405 there are limited accessories available. The best thing about Motorola radios is that they are built to last. The DP1400 is incredibly robust and will last an incredibly long time.
To summarise we have the very technically advanced TK-D240/340 which is a very strong and reliable radio. There is the more affordable Hytera PD405 that has the important features and we have the Motorola DP1400 which is greatly reliable because of how robust it is.
