The History of Motorola Two Way Radios

1937 was a year in which George VI was coronated, but also the year a breakthrough was made in telecommunications technology. Canadian inventor Donald Hings was the man who first made a portable radio signalling system, this for his then employer CM&S who were a mining and smelting company now more commonly known as Teck Resources Limited.

The first radio to be widely known as the more common name “walkie-talkie” was developed by current market leaders Motorola. Then known as the Galvin Manufacturing Company, a contract was received in 1940 to develop a portable, battery powered voice radio receiver/transmitter from the War Department of the US Government. The size of a backpack, the SCR-300 was used by the American Army, with around 50,000 units believed to have been built over the course of World War 2. This radio being a huge success for the American Military was later adopted by the British, using the design of the SCR-300 for the “Wireless Set No. 31” in 1947.

The first truly handheld radio was the AM SCR-536 yet again made by Galvin Manufacturing, only 3 years after the SCR-300 was made in 1937. Mass produced in 1941 this radio would also play a large part in WW2 with 130,000 models being manufactured throughout the war, with this model being carried by many of the first waves to hit Omaha Beach in Normandy alongside operatives of the SCR-300.

“Walkie Talkies” have long been used for military communications since first being introduced before the second World War. Modern day TETRA units are now used in line with Militant Forces across the world, with the ability to communicate on a variety of bands and modulation schemes whilst also including encryption capabilities. The advancement of technologies for the military now allows for use of GPS in order to help locate troops and their radios.

The SCR-300 would have been a rigorous exercise for the radio carrier, even with the lighter version B battery the radio still weighing 15kg, whilst also having an antenna that was 33 inches in length, and having an optional 10-feet 8 inches whip antenna. The SCR-536 on the other hand is a much lighter radio, weighing more similarly to the modern-day communication equipment at 2.2kg although the radio was extremely large in size.

Communication technologies has come a long way since the first system development in 1937, used for a variety of working environments radios such as the SCR-300 and SCR-536 have shaped the way people communicate in a vast array of settings.

Moving forward in 1947 was when Galvin Manufacturing Company changed their name to Motorola, a brand that would become a house hold name in terms of telecommunications devices both cellular and two way radios. From this point Motorola would go on to release the HT200 radio, a portable device that was classed as small and lightweight at the time weighing in at just 0.9Kg but nicknamed the “brick” due to its shape and durability.

Following on from the success of the HT200 the MX300 was released in 1975, these radios would operate on the 900MHz band. Including such features as status, identification and emergency alert features would set Motorola’s latest radio apart from the rest of the competition, this alongside its ability to work alongside computer-aided radio dispatch systems.

Motorola began their TETRA development in 1996, apha testing on the Island of Jersey in the March of the year. Also being awarded a contract to provide a TETRA radio system for the new airport in Oslo Norway, the airport that would go on to become the main International airport for both the capital city and the country as a whole.

In the most recent decades Motorola have continued to lead the way in terms of radio communications equiptment, with the GP340 being branded as the most popular radio ever made. Although discontinued in 2015 the radio is constantly requested by business buyers as it is still renowned for its quality, although not currently in production there are many newer Motorola models that share traits with the GP340. The Motorola DP1400 is currently one of the market leaders more popular radios, this alongside others such a the DP2400e and the DP4400e.

Although Motorola have long been the dominant force within a small space for communications equptment, companies such as Hytera and Icom are hot on their tails moving into the 21st century with more big things to come from all participants in the market.

Features For A Safer Workplace

Aswell as being a great form of communication for teams in the workplace, two way radios also house many safety features that could be the difference in saving a workers life. Here we have highlighted a few of those features, whilst some also have instructional videos showing you how they work.

VOX Voice Activation
VOX Voice Activation is a feature that is present on the majority of two way radios. A simple function that allows for hands free communications whilst using your telecommunications device, VOX is ideal for a variety of differing working environments. Some radios come readily equipped with a VOX function meaning that no additional needs to be taken, but should a radio not have it readily programmed accessories can be purchased that are VOX capable, from remote speaker microphones to headsets.

GPS
Global Positioning System otherwise known as GPS is a mechanism that will use a number of satellites in order to locate the position of a radio. Sending a signal back to a base station or repeater, this feature allows for a person to effectively manage their time via the knowledge of the exact location of each member of the team. Working hand in hand with another feature that we will mention, GPS can be useful when used in cooperation with the Man Down function, allowing for the operative to be found should they be in a dangerous position within the work place.

Man Down
A feature that is vital in dangerous working environments is Man Down. Whilst remote monitoring individual workers this feature can detect the orientation of the radio, detecting whether the radio is upright or not this will assume that the radio is on its side and that there is a problem at hand. Automatically detecting the issue, an alert transmission call for help will be activated and sent out to team members. Working similarly to how a smart phone works, whereby it can detect whether you are holding your phone in landscape or portrait mode, a system capable of GPS will also work in connection with this feature allowing for the operative to be found easily.

Lone Worker
Lone Worker is a feature that works in a similar manor to Man Down. Monitoring activity levels should the radio detect that it has been inactive for a pre-set period of time, 30 minutes for example, a sound will be played on the radio. If this sound is not responded to by the operative then an alert will be sent out to the other radios within the fleet, or initially to a base station for the operator to then dispatch someone to the scene of the incident. Lone Worker is often readily installed into many radios at a middle price point, radios such as the DP1400 from Motorola or the PD405 from Hytera.

Transmit Interrupt
Should an important messaged need to be relayed to a team quickly then Transmit Interrupt should be a feature of high priority to both you and your business. Should an immediate danger become apparent, Transmit Interrupt will allow for a high priority transmission to interrupt any ongoing communications between operatives. Transmit Interrupt can also be used for instances non urgent, whereby if a new set of instructions needs to be relayed then this is a great tool to use, allowing for effective and efficient use of workers tine.

Emergency Button
An emergency button is often present on two way communications devices, this is usually an orange colour and placed on the top of the radio. This can be programmed in order to raise and alarm to a base station or other radios within a group, if the devices being used have a display then the screen will showcase the ID of the radio in danger allowing for swift action to be taken. Seen on almost all radios, this is a safety feature that is of utmost importance in almost all working environments. Schools are able to take advantage of it should a disturbance be caused in class, or on a construction site where a person may be injured or urgent assistance is required.

The Right IP Rating For Your Business

The IP code that comes in connection with your chosen radio may be somewhat of a confusion to the average user. The official meaning behind this code is to classify the degree of protection your radio has against intrusion, covering things such as dust and water immersion for set periods of time.

The two digits following the IP both stand for protection against different substances, for example the first number is in terms of solids that your radio may come into contact with, whilst the second being in relation to water. Solids range from a rating of 1 through 6, whilst water is protected from a rating of 1 through 9K. Should a digit of 0 appear in either the solids or liquids position, then this indicates that the radio is not protected against said material.

Radios without an Ingres protection would be IP00, although this is extremely rare for a two way radio to have no Ingres protection, with the most common protection rating from manufacturers such as Motorola and Hytera being IP54. This covers the radio for a limited Ingres protection against dust, whilst also being safeguarded against splashes of water from all directions.

ATEX radios are designed to be used in some of the most dangerous working conditions in the world, environments such as mining, oil refineries and power plants are common places for these types of two way radios. Due to the high level of danger in place, the IP rating tends to be higher at IP67. This rating not only conceals the radio completely against dust, but also protects the radio from immersion in water up to 1 meter deep for around 30 minutes.

Differentiating working environments will determine the level of Ingres protection you will need for your radios, for example in an education environment purchasing radios that are IP68 rated would be completely unnecessary, where radios that are IP54 would be the more logical choice. Leisure centres can be dependent on the fact of if there is a swimming facility, should this be the case then a radio that is IP67 and protected against immersion in water would be a better fit.

Tips For Effective Communications

When using two way radios there are generally some unwritten rules on how to make best use of your communication devices. In order to make conversation easier between yourself and the recipient, various methods can be used.When first pressing the push to talk (PTT) button take a brief moment before relaying your message, this because there is a short delay with most radios before it begins to transmit. On newer releases of radios brands have began implementing a feature called time to talk, this sounds a bleeping noise until the radio is ready to transmit meaning that none of the communications are missed. Some radios that have this feature are the Motorola DP1400 and the Hytera PD505, although almost all current digital radios have implemented this feature.

Shorter talk time is also seen as the most effective way of communicating with colleagues. Due to only one person being able to transmit at a time, making a statement then waiting for acknowledgment before continuing with your next point allows for the person you are talking to being able to either agree or ask for further information on the subject. General terms are often used in radio communications, these may be things that you have previously heard not only via your own personal radio communications but in films and TV programs alike.

Radio Check – Can You Hear Me?
Read You Loud & Clear – Response to “Radio Check” Meaning Transmission is Good
Go Ahead – Ready To Recieve Transmission
Stand-By – Acknowledging the Message, But Unable To Respond
Roger/Ten Four – Message has been recieved/understood
Negative – No
Affirmative – Yes
Say Again – Repeat Your Message
Over – Message Completed
Break (x3) – Interruption due to Emergency
Come In – Asking second party to acknowledge they can hear you
Copy – You understand what has been said
Wilco – Meaning “I Will Comply”
Repeat – Used before repeating transmission

Identification is key in two way radio conversation, this because as mentioned before only one message can be transmitted at a time. Therefore, if a channel is populated with multiple radios in use, it may be unclear to other users who the message is directed towards. Identifying both who it is sending the message, and who it is targeted towards, unless of course it is aimed at a group of people then this should be made clear.

The NATO Phonetic Alphabet is the most widely used radiotelephone spelling alphabet. Created in order to avoid confusion, the Phonetic Alphabet allows for clear communications so that nothing is missed or misspelt. Recognised in a variety of languages, this alphabet is something that Radiotronics highly endorses to any company purchasing two-way radios, as if the work force is aware of it then it can make communications much more efficient.

Tips For Improving Your Radios Battery Life

A common complaint people have of their two way radios is the battery life not being sufficient. This can often be down to simple mistakes you may be making as a user, in this blog post we will be talking about methods that can be used in order to prolong the life span of your radio communication devices.

Vital to your working process, the batteries used in your two way radios are just as important as the body and features each singular device holds. When in communications with a team or colleague, your radio may be vital if the environment is potentially dangerous.

Starting simple, the volume of your device could be drawing large power from your battery without you even realising it. Something we are all naïve of is that thinking that listening to a device on a higher volume will use the same power as if we were to listen to it on a lower one. Often professionals using radios in a quiet working environment will leave their radios on full volume, a recommendation by Hytera states that should you be working in a place where the noise levels are fairly low, then by lowering your volume this can add hours onto your batteries charge life.

Although not always a possibility for various reasons, our second tip for prolonging battery life involves having a second spare battery on your person whilst working. Should you be away from base and recharging your battery isn’t an option, a second battery will allow for you to continue working without need for interruption. Obviously, this comes with monetary constraints, but this is the method which will allow for the longest use out of your two way radio.

Using accessories with your radios can also help to improve the battery life of your radio, although this is an added cost, a dramatic improvement can be seen when using a headset or microphone. Reducing battery drainage, earpieces are designed in order to improve both operating comfort and also efficiency.

Over charging your battery can lead to it deteriorating in power fairly quickly, as we often see with modern day smartphones whereby people leave them on charge whilst in use or for extended periods of time. Often with people blaming the manufacturers, the same can be said about two way radios. A common complaint that we have about batteries is there reduced power over the first year of use, but this can easily be rectified by numerous actions you can take. Ensuring radios are turned off whilst charging will not only allow them to charge quicker but will also help to prolong the lifespan, this alongside the fairly obvious resolution of just not leaving the radio in charge for longer than it needs to be. In modern times companies like Hytera and Motorola both offer smart batteries to go with their radios, this sufficiently improving the life span due to the technology involved, information on these can be found here.

The final tip is a fairly simple one in regards to the storage of your radios and batteries when not in use. It is advised by almost all manufacturers that your battery is kept in a cool and dry environment, this to ensure optimum energy storage.

Motorola DP1400 Vs. Hytera PD405

Motorola Solutions have long been market leaders in the radio communications market. Producing devices such as the GP340, which has been described as the most trusted radio device for the past 2 decades. Moving into more modern times, Hytera is hot on the trail of the communications giant. With popular models such as the PD705, and a technological first in the radio communications market with the PDC760, a radio which can act as both a two-way communications device and a smart phone.

In this blog post we will be comparing two devices from Motorola and Hytera, the DP1400 and the PD405 respectively. Starting with price, there isn’t much between the two with the PD405 coming in marginally cheaper at £119.99* and the DP1400 being £125*. Not only similar in price, a lot of the features are identical. With both radios working to both analogue and digital modes, broadcasting over UHF and VHF frequencies, and the two having a capacity of 16 channels.

*Price accurate of the date 22/01/2018

The DP1400 and the PD405 signalling types are similar also, with the two devices making use of CTCSS, DCS and DMR. Voice activation capabilities are present on both devices, meaning that should hands free contact need to be made by the user this is a possibility with the two radios. Alongside the radio body, a battery and antenna are included when purchasing each radio, with a charger being the only additional cost incurred when purchasing these devices. Although upgrades can be purchased for each radio, with a larger battery being an additional cost available should you need it.

Further safety features include lone worker. When purchasing the PD405 from Hytera, this is something which is built into the radio, but is classed as an optional extra with Motorolas DP1400. An important feature of every radio to be used for a working purpose is its safety rating, Motorolas device has a protection rating of IP54, this means that it has a limited ingress of dust and is also protected against splashes of water. The PD405 on the other hand is IP55, yet again being protective of dust but can also be protected against low pressure water jets.

Although not produced by Motorola, available from Radiotronics for the DP1400 are a variety of coloured shells for these radios. These can help to identify different divisions within your operation, or even if just a plane black radio isn’t quite what you’re after when purchasing a new fleet for your company.

All in all, both devices are market leaders at this price range, and are great options should you be looking to fit out your company with its first radio communications equipment. With both pricing and the features included on the device being extremely similar, it would be hard to pick a favourite from the two. All depending on what purchase you decide to make, these devices are definitely on option worth looking at for a variety of different working environments

Two Way Radio Range


One of the questions we get asked most frequently is:

What’s the range of your two way radios?

The problem with this question is that there are simply so many factors which can cause issues with radio communications signals. These include atmospheric conditions, obstructions such as buildings, condition of the two way radio battery and many other things.

Radio to Radio (Back to Back) – A Simple Answer

A simple answer is that portable radios are to be used for close range communications only. Some manufacturer’s state 5km, 10km etc. The reality is that would only be possible in ideal conditions with no obstacles and is unrealistic in the real world. So the best answer is when using two way radios in back to back (radio to radio) mode, you should expect no more than a mile or so in open land and no more than a couple of hundred meters in built up areas when outside; and no more than probably 100m when indoors.

Caveat with Licence Free radios: Licence Free two way radios (in the EU) transmit on 0.5w. Therefore regardless of line of sight, they may not produce enough power to give the radio signal enough energy to travel very far. Licensed two way radios, on the other hand, typically transmit between 4w and 5w. This is plenty of power to produce enough energy for the transmitted signal to be able to reach it’s maximum potential distance.

A More Detailed Answer – Line-Of-Sight

The fact is, there is a way to technically answer this question. But this is a technical answer and might be a little baffling for those who are not technically minded. Technical answers such as this rely on constants such as absolutely perfect and ideal circumstances and atmospheric conditions – which just do not exist in the real world.

Nevertheless, we can calculate the maximum theoretical range of a radio signal using a line-of-sight calculation which considers the curvature of the earth and presuming the earth to be a perfect sphere – which of course it is not. And this also assumes your radio signal is transmitted with sufficient power that is maintains enough energy to travel the distance.

The equation is:

  • horizon (km) = 3.57 x √ height (m)
  • horizon (mi) = 1.23 x √ height (feet)

The typically the height of an adult holding a portable radio when in use is 1.5 – 1.7m high. Let’s assume a typical height of 1.5m to be conservative.

  • √1.5m = 1.22474487139 x 3.57 = 4.37 km
  • √ 4.92126ft = 2.21837778568 x 1.23 = 2.72 miles

Using this theory, at 1.5m high, the point of the horizon is 2.72 miles (approx) which is the point where radio signals will unlikely be able to reach.

However, assuming that two users are both 2.71 miles (approx) either side of the horizon, in theory, given they are transmitting the signal with enough energy (watts), the very maximum distance you can achieve from a portable two way radio used back to back is 2.71 miles x 2 which is 5.42 miles. However, this is quite unrealistic. As mentioned above, atmospheric conditions, ionospheric absorption, and potential obstructions, will prevent this from likely ever being achievable.

For those even more technical, I agree that there could be a case to argue about diffraction and skip propagation etc. But for the purposes of this article, those points are not covered here.

TALKABOUT T82: Replacement For The TLKR T80

The release of the TALKABOUT T82 from Motorola Solutions has signalled the discontinuation of the ever popular T80 models, license free radios that have been market leading devices from the manufacturer. The last order date should you want to purchase this radio is the 27th April 2018, with delivery available to be scheduled up until the 31st October later in the year. There is the potential for more T80 models to be available after these dates, but this is only up until depletion of stock.

The T82 was released in July 2017, an upgrade on the still available T80 boasting many more features not previously seen on a license free device. VOX voice activation allows for hands free use of the radio, automatically transmitting should the user begin to speak, ideal when working in a manual environment, or when partaking in leisure activities such as cycling. Further adding to this is the device being IPx2 Rated, this means that the T82 is splash proof. An emergency alert button is also present on this radio, further adding to the safety features not previously seen on the T80 model, alongside its 16-channel capacity, a further 8 more than seen on the previous model.

One of the key features of the TALKABOUT T82 is having a dual power battery function. This allows for the use of both AA standard alkaline batteries or the NiMH batteries which are included in the box when purchasing this device. These devices are 800mAh and offer up to 18 hours battery life when charged fully, should this not be enough though, it is possible to purchase a 1300mAh NiMH which will extend the life of your device to 26 hours of use when fully charged. Charging your device is done by a micro USB, a single power point with a double headed USB connector allows for your radios to be charged from the same point. Should you want a more efficient method of charging, a drop-in charging deck is available to purchase separately.

If you already have a fleet of T80s but don’t need to purchase any more devices before the cut-off date, there’s no need to rush into a purchase as the T82 is compatible with its predecessor. Therefore when/if you need any further devices adding to your fleet, the T82 will work fine with your current models and there is no need to purchase an entirely new batch of radios.

Hytera PD705/705LT: The Everyday Radio

The Hytera PD705 radios are ideal for use in the construction industry, these are built to military standard (MIL-STD-810F) so are durable and able to withstand anything thrown its way. Being IP67 resistant this means that the radio is waterproof, allowing it to continue working should it be used when raining or if it were to be dropped into a body of water up to 1 meter deep. The Ingress protection rating also means that the device is dustproof, therefore working in an environment such as a building site is no issue for the PD705 range.

Both devices have a 48-channel capacity, meaning that there are enough channels to cope with anything from a small business right up to a large-scale operation. Available for both UHF and VHF frequencies, these devices can be programmed to suit the needs of the user, whether you need to enable your radios to work in an outdoor working environment or within a factory or leisure facility. Another option which the user gets is whether they would like their device to be analogue or digital. Pre-programmable text messages back to the base station are an option, whilst a channel announcement is also a feature on both devices due to the radio not having a display.

The PD705LT is just as robust as the standard version but has had unnecessary features removed. Both devices have the lone worker features as standard, but should you be looking for the option to have Man Down then this comes as an additional extra with the PD705. When purchasing the PD705 from the Radiotronics website, there is the option to add both GPS (device tracking) and Man Down to the device(s) that you are purchasing. Man down is a feature which detects whether a radio has been laid on its side for a certain period of time, a warning is then sent from the device and if not responded to then an alert will be sent from the radio to the control centre, an important feature should you be in a dangerous working environment. A priority transmission can be sent to all devices within the fleet, should an important message need to be sent to all teams or a safety warning of sorts, these transmissions will interrupt any other calls which are taking place at the time
