Tamworth Manufacturer case study

Tamworth manufacturing business approached Yesway, seeking to improve their factory communications system.

The Tamworth factory already had an aging analogue license free PMR446 radio system, but there were coverage issues.

Yesway travelled to the clients Tamworth site, and carried out a full equipment inspection, and comprehensive site radio range coverage survey.

The clients manufacturing premises are spread across two separate sites, with a road between them.

This combined with the fact that the buildings were largely metal structures (which radio waves don’t like), presented am exciting challenge for our Yesway communication experts.

Of course being Yesway, we were up for the challenge, and tested a couple solutions, until we succeeded in providing full radio coverage across the sites.

Our solution involved using the latest  DMR digital radios from Entel. 

Unlike many handheld two way radio manufacturers antennas, the Entel antennas need to be cut to the resonant frequency.

This ensures that the maximum signal power is leaving the antenna.

Using radios with antennas cut to the resonant frequency, allowed us to achieve full site coverage, without the need of an expensive additional repeater.

We improved safety and production efficiency for the client, and the client is delighted.

History of Two Way Radio

Radio communications systems started to appear in the late 19th Century, with pioneers like Marconi sending signals across the Atlantic by morse code.

Soon such systems were being rapidly adopted by both government and industry, as an alternative to the existing ‘Wired’ telegraph systems.

Radio offered advantages over the Telegraph system, due to cheaper infrastructure costs. This is because the telegraph system required purchase and installation of telegraph wires & poles.

Radio communications on the other hand, did not require expensive long distance wires, and the installation of many telegraph poles.

Radio proved to be particularly cost effective compared to the telegraph, for international communications, which required undersea cable installation.

There were some  disadvantages of early radio communications systems however.

One such disadvantage was call privacy, as early radio systems did not use the modern encryption methods available on radio systems today.

This meant that confidential messages, could be easily eavesdropped, by ‘Third Parties’.

This was an issue for both government and business users, but modern systems have overcome this.

A famous early example of radio communications use, was the ‘Titanic’ ship disaster of April 1912. The Titanic being a state of the art ship, had been equipped with a two-way radio system, which used Morse Code for communicating messages.

As the ship was sinking, radio messages were able to be sent out for help, and it was the first time that the new emergency code ‘SOS’ was used.

Although there was a massive loss of life, many lives were undoubtedly saved due to being able to get the message out to rescue ships in the area that they were sinking.

Without radio communications, the first indication of the disaster would have been, when the ship failed to arrive in New York as scheduled.


In 1922 the BBC was formed in the UK, and for the first time the ordinary (non geek) public were able to experience radio. Although public broadcasting is only one way communication, it is worth mentioning as a milestone in the history of radio communications.

World War Two necessitated innovative approaches to communications, and the american company Motorola was the first to develop a handheld portable ‘Walkie Talkie’.

As the Transistor and solid state electronics were not invented till the 1950s, the wartime Walkie Talkie used ‘Thermionic Valves’ (Tubes in the USA). This meant that they were not particularly efficient, and quite large in size.

The Motorola designed Walkie Talkie was however an important step forward in radio communications development.

Private commercial use of Two Way Radio by businesses in the UK started just after the war in the late 1940s. This allowed businesses to instantly communicate with there drivers out on the road, and was very useful for Taxi firms.

Early equipment was not particularly efficient compared with the latest Digital & Analogue radios available now. Reasons for this include, inefficient use of frequency bands (wide bandwidth), and less efficient electronics available to the designers of the equipment.

In equipment prior roughly to the 1980s, the frequency that the radio was required to operate on (set by what is now OFCOM), was controlled by a ‘Crystal Oscillator’.

These had to be custom made for a particular frequency, and then installed into the Two-Way Radio. Once installed, they needed to be set up using a Radio Communications Test Set.

Modern equipment does not require crystals to be purchased and installed, but does instead require the radio to be connected to a computer system and programmed to the required frequency and options.

Modern Two Way radio systems are sometimes also integrated into the internet, and it is possible to communicate using a handheld Walkie Talkie, from a field in the UK to a factory in Australia.

To do this the signal is recieved from the handheld radio by a Digital Repeater Base station located near and within range of the handheld radio. The voice signal is then fed onto the internet by the Repeater.

At the Australian end is another internet connected Repeater, which then transmits the voice signal out to the nearby Australian factory workers handheld Walkie Talkie.

When the Australian worker talks back, the process works in reverse.

Should I buy secondhand radio equipment

secondhand radio equipment


We often are contacted by people who have, or are considering buying secondhand radio equipment from auction, and other websites. They often want us to reprogram the equipment, which we can do for £20 + VAT per unit.

According to the UK distributor of two-way radio equipment, they recommend that the reliable lifespan of handheld radio equipment, is between three and five years.

Whilst secondhand equipment might fine for non safety critical applications, in other words if no ones life could potentially be impacted by equipment failure, we recommend new equipment for peace of mind.

For example if you run a security firm, then you are potentially putting your employees well being at risk, if the radios fail at a critical time.

Are you as an employer prepared to take that risk?

If not then we can supply brand good new equipment from £130 per handheld radio. Your choice of course!

Why mobile phones can be an expensive business communication solution

A number of years ago when I worked for a Worcestershire based two way radio company, mobile phones were starting to seem a viable alternative to two way radio for large organisations such as councils.

Indeed some council departments and private companies replaced their free to call, two way radios with mobile phones, believing that the call packages offered by the mobile phone companies would work out cheaper than the cost of maintaining a fleet of two way radios.

What happened was that they had no control over call cost expenses, and it was expensive, slow and almost impossible to send a ‘group message’ from the base controller to all personnel quickly.

An example was in  an emergency situation when you did not want you vehicles and employees to be in a certain location. With mobile phones it was slow and inconvenient to have to call up each employee, whereas with two way radio, all users could be contacted simultaneously which aids safety in an emergency, and has no call costs involved.
