We are restructuring!

We are pleased to inform you that we have merged with another local supplier, Push To Talk South Africa (Pty) Ltd [PTT SA].

We negotiated this restructuring venture in order to add additional support and two way radio communication equipment to our existing product portfolio available to all DRS customers.

A Group Call, as the name suggests, is when you send a voice message to multiple recipients.

Think of Group Calling as the RF version of a WhatsApp or Skype Group Call/Message – you can send crucial information to all the members in your team(s) at the same time. The only difference is that, when you transmit your voice call with your two way radio, your team members will hear the message over their radios when you send it (you don’t have to wait for them to first accept your call or download your voice note).

When your Group Info has been programmed, your radio dispatcher can simply select the appropriate group(s) that they need to contact, either by manually dialling the designated group code, or selecting it from their contact list.

With modern Radio infrastructure and associated digital functions, reaching out to multiple people has become easier than ever before. There is no need for any of your Team Members to miss out on crucial information. This priority broadcasting function is especially useful in the public safety and security sectors.

Please contact our Sales Team if you’d like to know more about our Radio options that can facilitate Group Calls.

For over a century, Two-Way Radios have been used in multiple sectors. We find it quite impressive to think that, in a world where tech devices are replaced so quickly, the walkie-talkie is still relevant today.

Over the years, two-way radio devices have definitely evolved to adapt to our ever-changing needs and requirements, but can they really outperform phones in the workplace?

Let’s first have a look at some of the mainstream modes of communication available:


As the name suggests, landline telephones require fixed locations and an infrastructure relying heavily on extensive cable networks. In South Africa, these are usually installed and supported by Telkom.Fixed lines may be perfect for people working in office desk jobs, but they are much less practical for the factory floor, construction site, school grounds, university campus, or any other work site that requires workers to be mobile while talking to each other.

Fixed lines may be perfect for people working in office desk jobs, but they are much less practical for the factory floor, construction site, school grounds, university campus, or any other work site that requires workers to be mobile while talking to each other.


Mobile phones and smartphones offer excellent mobile communication as long as their batteries are charged and they have adequate signal strength. However, mobile coverage is notoriously inadequate in some and totally unavailable in other areas, for example, remote areas and indoor spots like elevators, stairwells and underground tunnels. Furthermore, cellphone service (GSM networks) are easily overloaded in an emergency, rendering it useless when needed most.


Sending texts or emails are great options for people who are (more) comfortable with instant silent communication, but some people are just more comfortable when having an actual voice conversation – and some information simply must be conveyed by voice. Such scenarios render text and email useless.

Digital two-way radios with keypads and displays can be ideal for texting along with all of the other benefits they provide.

Now let’s contrast them with some advantages of two-way radios:

Mobile & Durable

Two-way radios are more durable in rugged environments and often meet waterproof and dustproof military specifications so they can be used effectively just about anywhere.

Unlike cellphones, obstructions are not a major challenge. Your two-way radios might just require added power or the addition of repeaters to increase signal range. In larger facilities and across vast campuses, distributed antennas and bi-directional amplifiers can even boost signals further in even the most challenging environments. This is why two-way radios are so essential in jobs like warehousing, security or property management where users have to roam over wide areas.  

Push-To-Talk (PTT)

On two-way radios, users push just one button to talk to each other, saving the trouble of scrolling through a contacts list and workgroups can be programmed to give users the choice between communicating with a whole team, or with other users one-to-one.

This flexibility makes workers much more efficient and it’s invaluable in emergencies or other situations where critical communications are vital.


With a cellphone or landline telephone, you have no choice but to wait for the call to 1) connect and start ringing, and 2) be answered. On a two-way radio, one-button functionality enables instant voice communication as soon as you start talking.

Instant communications are not only vital in any emergency when delays can cost lives, but also to speed maintenance technicians to the site of production line breakdowns or to help sales staff check with the warehouse to see if more products are available.

Group Call

On a two-way radio network, a single user can call an entire group of people with the push of one button. Ever tried to set up a conference call or find different workgroups using a cell phone in a hurry?

Digital technology makes radios even cooler:

Digital radios convert voice signals into packets of data that can be transmitted over traditional networks, both wired and wireless. This makes your two-way radio a computing device that can send texts, receive text (including emails) and transmit voice signals around the world via the internet.

Digital radios also improve sound quality in noisy areas, and they use less battery power than analog radios, which means you can keep them on the job for longer periods of time.

They can even generate user data that can help track people’s locations and identify inefficiencies to help make businesses more profitable.

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).


Trunking is a cost effective radio communication technique that makes communication significantly easier and more effective than traditional radio communication methods systems such as ComReps (Community Repeaters), where different users operate on separate radio frequencies or radio channels.

A challenge with traditional radio systems is that the number of channels is often exceeded, whilst radio trunking smartly controls and guides the users toward a free channel, thereby reducing waiting times.

The principal of trunking is based on automatic and dynamic allocation of a small number of radio channels among a large number of radio users in the most efficient and transparent way.  Finding a free channel is therefore not the user’s obligation as the system does it automatically and in the shortest possible time.  Trunking therefor permits a large number of users to share a relatively small number of communication channels.

This process is managed through tried and tested control equipment and the entire allocation process is transparent to the individual user.  Radio trunking enables a dispatcher to be in instant contact with vehicles in the fleet as trunking optimises resources to reduce queues and speed up channel allocation.

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.

A walkie talkie (sometimes also referred to as a handheld transceiver, HT, two way radio, or just a portable) is a hand-held, portable, two-way radio transceiver.

They were originally developed during World War II and everything about their design was initially geared towards the needs of armed forces, but after the war, they also spread into the public safety sectors (eg. police departments) and was eventually also used commercially.Stacy Bravo notes that, over the years, with the advancements of technology, walkie talkies have often times been overlooked as a necessity in today’s world and thinks that everyone in every household should have a set.

The most common two way radio rental contract we offer, is the 12-month minimum contract. This contract allows you to continue renting the radios from us on a month-to-month basis after the initial twelve month period has expired, and payments are collected via debit order every month, but we can personalise the rental terms it to suit you.

Obviously, the sky’s the limit, but there are four basic rental contracts we offer:

Hire Purchase
Under the terms of these type of contracts, we can discuss & agree to a fixed rental period, during which you will basically pay off your hardware purchase. In other words the radio(s) will belong to you after the fixed rental period (lease period) has expired.
In addition to this “down payment” option, you can also add airtime rental to the bundle if you do not have a frequency of your own.

Radio + Airtime
If, however, you do not wish to purchase the hardware or your own frequency from ICASA, we can discuss and devise a plan by which you can rent both the hardware & the airtime from us.

Radio Only
If you do not wish to purchase the hardware, but you do hold a current valid Spectrum frequency license from ICASA, we can help you out any time. We will just require a copy of your frequency license upon signing of the contract. This will be placed on your file, and you may be requested to send a renewed copy each year for as long as you use our rental radios.

Airtime Only
The other option you could consider, is to settle the hardware purchase once-off, and then just rent our frequency if you do not have your own.



We know that many people in the Events Management sector, often need better communication than cell phones, but only for a short period of time (once-off, or annually). If this is the case, we are still happy to assist. Usually, it is best to contact us ahead of time (a few working days would suffice) to allow enough time to determine the perfect radio + airtime to match your delivery/collection requirements, your event’s location, as well as the surrounding area & all possible communication barriers such as buildings, long distances, etc.
