Hytera Psuedo Trunking

advice on which is the best base station

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.

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 Advantages for Uk Farmers in 2017

Hytera digital radio

Two- way radio Advantages for Uk Farmers in 2017

Farmers are increasingly choosing to use two-way radio 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 Hytera PD705, which is IP67 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.

How to Incorporate Modern Digital Radios With Older Analogue Farming Radio Systems in 2017

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 2017, 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 radios, 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.

Long Range Event Communications

Handheld mobile radios are great for cheap reliable communications, however communication range can be an issue for some events that take place over multiple sites in Lincolnshire for instance.

Yesway of Lincolnshire  can provide trunked repeater based solutions for your event which will out perform conventional two way radio systems.

An event split between a site in Lincoln & another site in London for example could reliably communicate using handheld walkie talkies, via our national trunked repeater network.

Get in touch, and we will be happy to help in any way we can.

Regards

trunked radio repeaters

Trunked radio repeaters offer the user wide area communications for their business as well as an effiecient use of the radio spectrum.

Trunked radio repeaters use digital signalling to allocate a free frequency channel to the radio wishing to transmit. This allows for many users to share a trunked repeater.

 

We offer repeaters that cover most of the Uk, and trunked repeaters are great for security firms, taxi firms and farmers.

Aerial spotting in Lincoln

what is lora

Aerial spotting

Recently we went aerial spotting  for communications aerials around Lincoln.

We cunningly disguised ourselves inside a number 15 bus, armed only with our eyes.

For those people who say that two way radio communications is a thing of the past, I have news for you.

There are many business radio antennas on chimneys and roofs, as well as on vehicles, proving that radio comms is alive and well.

Its not just two-way voice communications that is being transmitted, telemetry and the rapidly expanding Internet Of Things is resulting in an antenna increase.

Types of Aerial

Vehicle Aerials

Many of the latest vehicle antennas can be very discrete, so you have to keep you eyes peeled to spot them, and some re even deliberately designed not to be seen.

Probably the most common type you will see on a vehicle is the vertical dipole whip.

These ‘whip’ antennas (aerials) often are attached to a magnetic mount base, that can be easily attached to a metal vehicle roof.

This saves having to drill holes in the vehicle, which is less popular these days, as many business vehicles are now leased, rather than owned.

You may have noticed that the whip aerials on vehicles such as taxis, vary in length. This is due to resonant frequency.

For a transmitting antenna to work at maximum efficiency, it needs to be made for a specific resonant frequency.

Whip aerials on vehicles often come as a long length, which needs to be cut to the correct length.

Short Steel  Whip Aerials (around 15cm long) are operating in the UHF frequency band, roughly around 450Mhz (Mega Hertz).

Medium length Whip Aerials (around 45 cm) are probably operating in the VHF wave band, roughly around 160Mhz.

Long length steel whip aerials (typically around 91cm long) are either operating in VHF ‘Low Band’, around 77Mhz, or have not been cut to the correct resonant frequency .

One our aerial spotting trip, we saw many examples of both the medium and long length (VHF) aerials on taxis around Lincoln.

Yagi Aerials

A Yagi is a directional Aerial (Antenna) created by a Japanese inventor (hence the name).

This is probably the easiest and most common aerial that you will spot.

The Yagi aerial is most commonly used for television reception, and therefore most houses have one strapped to the chimney.

You may also have spotted Yagi antennas situated on land owned by water, gas and other utilities. These are used for sending and receiving telemetry.

The Yagi is a directional aerial, which makes it good at receiving and transmitting signals in one direction.

Therefore next time you spot a yagi, have a look at which way it is pointing. The way it is pointing will be the small end (away from the pole it is mounted on).

Other Types Of Aerial

There are  quite a few other types of Aerial, such as Co-Linear, Microwave  and Satellite Dishes, and we may extend this article to include them at a later time.  Alternatively for advice, contact us.

Aerial Coax

Aerials (Antennas) are connected to the radio receiving and transmitting equipment by a special cable, abbreviated to Coax.

Coax is short for Coaxial Cable, and is available in a number of types, suitable for different radio operating frequencies and applications.

Careful selection of the correct cable is crucial to ensure that your transmitter / receiver works well.

The use of an incorrect type of coax, can actually risk damaging transmitting equipment, as not all the RF power will travel up to the aerial (some will be reflected, back down, etc)
