Hytera Psuedo Trunking

Traditional radio trunking systems use a digital control channel to allocate users a free communications channel when they wish to talk. It lets the other users in the ‘group’ know which channel they (the radios) are using.

This system is more efficient than conventional two-way radio communication, and allows more groups of users to share a limited set of frequencies.

Hytera Psuedo Trunking is a system only available from Hytera. It allows two separate conversations to take place at the same time on the same channel. For example a council could have their refuge department and also their park ranger department talking to members of their respective departments at the same time, and not be aware of the ‘other’ department using the channel.

Yesway Digital Communications can provide the Hytera DMR Psuedo Trunked system for your organisation.

Two-way Radio for Farms

For Agriculture

Farmers are increasingly choosing to use two-way radio for farms, instead of mobile phones for a number of reasons:

1)   Higher reliability than mobile phones in sparse rural areas  due to poor phone coverage.

2) More rugged design of two-way radio handsets. Models from Hytera  & Tait for example can survive being dropped on the hard ground, or even into water.

A handheld radio that we would recommend for farmers is the Entel DX482, which is IP68 rated. This means that it can withstand being dropped in water, so is perfect for outside work activities.

3)   Time saving because you just press transmit & talk, rather than having to dial a number & wait for connection. Great for emergency situations, & a safety feature.

4)   Cheap to run, as you have no call charges to pay, and your employees can’t make private calls, costing you money & lost time. For handheld only use, a 5 year Ofcom licence can be obtained, for only £75.

The licence allows use of a number of  shared frequencies, and is not area dependent. This means that you can use the handheld radios throughout the UK, without being restricted to a particular set geographic area.

5)   ‘Lone Worker’ features from manufacturers such as Vertex-Standard allow safety monitoring of workers, which helps farming safety.

6)   Range can be extended worldwide through the use of repeaters, and other modern IP technology, so distance now no object for modern two-way radio for farms.

Radio Migration from Legacy Systems

Many farmers already have existing radio systems that have been in place for many years.

Unless the system is less than five years old, then it is likely to be what is known as ‘Analogue’.

Even if the system is newer than five years, it could still be analogue, rather than Digital, as the price of analogue until recently was quite a bit less than Digital.

These days, in 2021, the price difference between the older Analogue radios, and the newer Digital radios has narrowed, and we would recommend Digital.

The reasons for us recommending farmers start to migrate their existing Analogue radios to Digital include:-

  • Better coverage at the fringes of transmission range.
  • The voice quality stays great at the fringes of coverage, and does not suffer interference.
  • Battery life of handheld radios is better, compared to analogue handheld radios.
  • Digital radios are harder to eavesdrop on.

You can keep your existing Analogue system, and gradually replace the radios with the more modern digital system, using what are known as ‘Migration Radios’.

These two-way radio for farms, such as the Hytera PD415 handhelds, are capable of operating in both Digital & Analogue modes.

Therefore you can could for example communicate in digital mode between two PD415 radios, whilst also being able to communicate with your older analogue radios as well (in Analogue).

These ‘Migration Radios’ , such as the Hytera PD415 offer farmers the choice to avoid a large initial expense of a new Digital System. Instead, farmers can gradually replace their existing Analogue radio system over time.

Repeaters

Repeaters are devices that boost communication range.

Repeaters receive a weak signal and retransmit it, improving two way radio for farms.

By retransmitting the signal at a higher power, further range is enabled.

Another reason to use repeaters, is obstacles.

Obstacles include both natural and manmade structures.

Examples of natural obstacles include hills and mountains.

Examples of mademade obstacles include buildings and bridges.

Obstacles matter to radio signals.

Basically they block or attenuate radio signals.

Attenuation means reduces the power of the signal.

Reducing the power of the signal, reduces communications range.

A classic use of a radio repeater is to overcome a hill.

Hills will block radio signals above 30 MHz.

Radio signals above 30Mhz are normally known as ‘line of sight’.

The term ‘line of sight’ is slightly misleading, as signals will pass through a building.

Therefore you don’t actually have to be able to see a clear path between transmitting and receiving radio.

However hills block radio waves, so a hilltop repeater overcomes this.

Placing a repeater on a hill allows signals to be received from one side of the hill, and boosted to both sides of the hill.

This is because the repeater antenna is physically above the top of the hill.

Why VHF isnt always best for Farmers

VHF is short for Very High Frequency, and refers to the range of frequencies within the electromagnetic spectrum.

The frequencies classed as VHF range between 30 MegaHertz, up to 300 MegaHertz.

MegaHertz btw is a million Hertz, and is useually written as MHz.

Many farmers with existing systems are operating on VHF.

This is the case for a few reasons:-

The first reason is that traditionally VHF equipment was cheaper than UHF equipment to purchase.

Therefore farmers who have had systems for many years, may have gone VHF for this reason.

A second reason for the popular choice of VHF among farmers is theoretical range considerations.

In open countryside, without signal reducing objects in the way, VHF radio signals should travel further.

I say should because thats the theory based on physics, but not necessarily the real life experience.

Metal Buildings

Buildings are one type of physical object that can block radio signals from reaching their required destination.

Buildings can either totally block the signal, or reduce the signal level, therefore reducing communication range.

Metal buildings can be a particular problem, and from my experience, especially at VHF frequencies.

Wavelength

Wavelength is the inverse of  the radio frequency.

What this means is that a frequency of 160 MHz will have a longer Wavelength than a radio frequency of 460 MHz.

A longer Wavelength (lower frequency) will have a harder time fitting into small spaces (im not making this up btw).

The longer wavelength at VHF compared to UHF (Ultra High Frequency), sometimes prevents communication in small areas of buildings.

Why not use an in-building Repeater

You could use a device called a repeater inside the building, to improve coverage, but why.

What we have found from experience, is that the additional expense of an in-building repeater, can be avoided through careful antenna optimisation and choice of frequency.

UHF in our experience actually performs better for farmers with metal buildings, as the smaller wavelength can get through doors and around internal objects better than VHF.

Conclusion

UHF in theory won’t go as far as VHF, but it very much depends on where on the farm you need to communicate with.

Rather than just buying an off the shelf solution, we tailor our solutions to meet you communication requirements.

In the real world UHF may be better, especially if you mainly wish to use handheld radios.

The two-Way Radio Dealers in Lincolnshire

We are based in Lincoln, Lincolnshire and provide a comprehensive range of two way radio services throughout the county and beyond.

The business started as a part time ‘Sole Trader’ business back in November 2010, and has steadily expanded since.

Today we are limited and VAT registered, and able to supply and advise on two way radio, as well as offer training services.

Our telephone number is (01522) 740818, and we look forward to hearing from you.

If you are involved in organising an event, you may be interested in the guide to using two way radio in events. It can be accessed by clicking here.

If you would like to have us come to your business, and show you how two way radio can improve business efficiency, then we would love to hear from you.

A radio that we would recommend for outdoor environments is the British designed Entel DX Series radio.

We recommend this radio for outdoor activities, because it has an Ingress Protection, or IP rating, of IP68.

IP68 means that the radio can actually survive being dropped in shallow water.

We have demo Entel DX series radios that we can show you in action, and the radio is proving very popular with buyers.

For a reliable radio for internal business use, such as light manufacturing, we would recommend the Hytera PD405.

The Hytera PD405 has proved very reliable in the factories that have purchased the radios. In fact we have never had one go faulty!

If you are a business in the marine or offshore industries, then you may require radios for use in potentially explosive environments.

These types of radios are known as ‘Intrinsically safe’ or ATEX radios.

ATEX radios are designed for use in locations where a spark could potentially cause an explosion.

An example of an area that would require ATEX radios, is a ships battery room, as gases released during charging of the backup batteries, could potentially ignite.

We offer a bespoke service tailored to each clients individual needs.

Therefore we don’t expect you to be an expert in radio, that’s our job.

What does UHF stand for?

UHF in radio communications  stands for ‘Ultra High Frequency’

The UHF frequency band covers the range between 300 – 3000 Mhz (Mega Hertz).

UHF in radio communications is particularly useful in built up area such as cities, as the ‘wavelength’ is shorter the higher up  in frequency you go. This means that the shorter wavelength (compared to VHF) allows the signal to theoretically  go round  and through objects better.

Another advantage is that the aerials are shorter than with vhf equipment (remember higher frequency = shorter wavelength = shorter aerial). This is particularly useful for discreet and covert police operations. Shop security radios are also normally UHF.

A theoretical disadvantage of UHF compared to VHF is a shorter transmission range, though there are lots of factors involved in deciding which system will work best, and UHF systems  can be made to go long distances (worldwide in fact) by using it  in combination with the latest  internet combined technologies.
