If you have already tried buying some two way radios (walkie talkies) for yourself, you will now know that there are quite a few ICASA rules and regulations that needs to be adhered to.

One of them, is the fact that you need (a) your own ICASA Spectrum frequency, or (b) permission to use someone else’s (eg. Radio Rentals).

We would be happy to see what type of Rental Arrangement we can come up with to suit your communication needs and resources, but if you still prefer to just pay & go, have a look at the Vertex Standard VX-241 license-free walkie talkie.

This rugged little buddy, needs no proof of frequency licenses or radio certificates before it can be purchased. It comes pre-programmed, and the range on it is about 3 km (line-of-sight).

Various optional accessories are available for this handheld radio, but what comes standard in each box, is:

  • Antenna (fixed onto radio)
  • Battery (1380mAh Lithium Ion)
  • Charging bucket (cradle) & Adaptor
  • Belt Clip
  • User Manual & Safety Guide

Oh! And have we mentioned the 12-month product warranty? It covers all mechanical failures on the radio for 1 year from date of purchase (same warranty as on all other Vertex Standard radios).

We live in an age of constant technological advancement, so it is no wonder that even two way radios have gone digital.

One product, we’re specifically excited about, is the Vertex Standard EVX-Link. This little box of magic, makes it possible to extend your digital two way radio network as far as you want it to go, without the need to invest in various repeater towers, antennas, etc.

In addition to such innovative accessories, if you compare an analog two way radio with a digital two way radio, you’ll notice that the digital radio’s audio quality is also much better – not only because it doesn’t gradually deteriorate the further your radio users move from away from each another, but also due to a crisper sound and less background noise.

The increased static you’ll hear on an analog two way radio the farther out you go, might be quite obvious (we’re talking RF signals here), but as for the rest, we’ll let Bearcom explain why:

With analog two-way radios, the natural human voice is carried by radio signals. You can hear the person’s voice exactly as it sounds, and interference, obstacles, and coverage limitations can significantly degrade quality. In contrast, digital radios create an electronic version of our voices. The vocoder inside the radio converts traditional analog voice signals into positive and negative binary signals, and transmits this digital information to the other radio. Then the vocoder on the other end translates the signal back to an analog voice, so the signal goes from analog to digital and back to analog.

One of the major shortcomings of an analog radio system is that once you push the button to talk, you’re speaking into an open microphone that picks up any nearby noises and transmits them along with your voice. A digital radio is designed to do a much better job of filtering out background sounds that can clutter analog transmissions. The vocoder essentially knows how to turn up the human voice and turn down everything else. That’s because the vocoder has been programmed to identify the sound of people talking.

This is probably the most frequent (if not the first) question posed to members of the two way radio community. We wish we could give you a clear-cut, rule-of-thumb type of answer so that you can apply it to every communication scenario, but due to the way two way radio frequencies work, there are simply too many factors at play.

What we can do for you, in today’s blog post, is to give you a rundown on the most important facts to consider when trying to pinpoint which two way radio solution will work best in your environment / set up.

  • A fair distance expected from a standard VHF/UHF commercial two way radio, is about 1 – 2 km.
  • The ideal (optimal) area would most probably be one with perfect line of sight, in other words, an area in which there are no peaks / buildings / structures obstructing the view between two users.
  • Contrary to a common misconception, the range of analog and digital radios are the same. The only difference is that analog radios’ audio quality will continue to decrease gradually the farther away one user get from another, whereas the digital radios’ sound will remain just as crisp and clear until range is eventually lost (it will cut out as soon as range is lost).

You can, of course, purchase additional equipment to extend your reach. Renting or purchasing a repeater, with its own duplexer and antenna mast (usually a dipole antenna on top of a aluminium pole), used to be your only two options; but thanks to Vertex Standard, if you have a digital network, you can now also link your sites/users via an internet line and their new EVX-Link system.

The feature-rich VX-260 Analog Series VHF/UHF portable radios will include enhanced audio output, expanded interoperability, programmable emergency alert and a universal battery system. The inclusion of the universal battery system or “UNI” allows users to consolidate down to one battery and charging platform for their Vertex Standard fleets.

Ever heard the terms ‘Lone Worker’ or ‘Man Down’ with regards to two way radios? Are you still trying to figure out what they mean?

Basically, these are two functions that can be activated (programmed) on certain radio models, such as the Vertex Standard VX450 Series.

Lone Worker

Let’s say, for example, that you have security personnel performing ground checks a few times a night. Let’s also say that they don’t perform these security checks as teams, but that they’re responsible for handling them on their own. What if one of them walked into a seriously dangerous situation? How will they be able to let you know that they need help without alerting the intruders?

Switching a Vertex VX450 portable onto Lone Worker mode means that it will have a built-in timer that will require the user to reset it at a predetermined interval, and if not reset, the radio will automatically switch to Emergency mode to alert the rest of your network users that he/she needs help.

Man Down

For this explanation, let’s assume that you are part of a team of firefighters. The nature of your job would mean that, whenever you are working at a scene of a fire and one of your team mates stop moving, it is extremely likely that something is seriously wrong with him/her.

The Man Down programmable functionality on the VX450 portables means you can set it up so that the radio will monitor a worker’s degree of motion by adjusting the settings of its 3-axis sensor. The moment any of you stand still for more than a predetermined period of time, the radio will send an Emergency Alert to the rest of the team.

Apex Radio also wrote an informative piece about these functions – you can read it here.

You reap what you sow – change to Vertex Standard’s digital eVerge series and Evolve to Better.

Agricultural specialty services provide a necessary backbone for the U.S. farming industry. When their operations are less than optimal, crops are affected.

But with good communication – and Vertex Standard – there are rewards to be reaped.

When moments matter, the Transmit Interrupt feature on Vertex Standard’s EVX-530 Series allows a user to halt a current transmission and make way for critical messages when they need to be heard.
