The client software for Windows, Macintosh, Android and Apple is available at the respective links. Sadly Linux is not currently supported (why?). These clients are for network radio usage. Zello is a free application turning devices into a two way radio at no extra cost, although it is best used on a dedicated network radio such as the Inrico range - I currently own a T710 which I also use on the amateur radio related channels. My intention is to set up a channel for use by the DFDN (I have created it already on Zello);- it will be for family and business related use and therefore password protected to keep us free of malicious usage. I myself will have administrative access, my ladies, daughters and anyone working for us will automatically be trusted in. Others my be added at my own discression. The network can be used worldwide on any supported device, so long as internet access is available.

For an explanation of how a dedicated network radio may be better siuted for some users, see below.

To find our channel on zello, please search under 'channels' for DFDN.ORG - the password is available by sending a message to Email : norrisdavid1297@gmail.com - and I will trust you in. Any problems? Get in touch!

Users, once trusted, can listen, speak and can send text messages also, at no cost to themselves using a device they already own, or alternatively, an issued network radio.

Reasons Network Radios And Zello Are a Perfect , and cost effective, communications solution

Of course, Zello can be used by users on a normal Apple or Android phone they already own. This is expected to be the case for my ladies and others joining the business subsequently, which may include my existing daughters, future children and as capacity is increased, external employees, contractors or associates - who in principle, may be working remotely, possibly in other countries.

Where needs dictate, they may subsequently be outfitted with a network radio - of which the Inrico T710 is an example.

Though Zello is most commonly used on consumer devices like smartphones, It is highly reccomended for, and fully compatible compatible with, network radios. These incidentally require no licence to operate. See below for an explanation...

Benefits of network radios - when compared to smartphones...

Handheld network radios look and function like traditional two-way radios (a.k.a walkie-talkies, DMRs, or ham radios). But, instead of using UHF/VHF frequencies to connect, they connect via the Internet using a SIM card or Wi-Fi signal.

Mobile network radios have a number of advantages for use in noisy outdoor environments like construction sites, manufacturing plants, and transport truck cabs, including:

1. Simplicity & Safety with Network Radio Transceivers:

Instead of a smartphone, some users opt for a network radio transceiver. Featuring large buttons and knobs that can be mapped to Zello functionalities, this is a great solution for deskless workers, such as drivers and construction workers, who wear gloves or operate a vehicle and can’t take their eyes off the road, as it removes the need to fumble with an unlock screen or any other paired accessories.

2. Zello + Network Radios Offer Lower Costs:

Network radios cost as little as $75. Paired with the Zello network radio app, which is free, companies can outfit their teams for 80 percent less than if they purchased digital two-way radios or smartphones.

3. Network Radios are Rugged:

Network radios are made to stand up to the elements. The best are even waterproof. No need to worry about drops or falls. The best network radios can take a beating in demanding outdoor environments.

4. Don't Miss a Sound:

These devices are intended for construction sites, factories, and the road. While smartphones can be hard to hear, network radios provide clear audio at high volumes in situations with a lot of background noise without the use of accessories like external microphones or earpieces, although as bluetooth is supported by most network radios, bluetooth accessories can be used where desired.

5. Zello Improves Battery Life:

Network radios have a much longer battery life than a smartphone. Our tests show that network radios running Zello can operate for up to three days before needing a charge, an important feature when the power is out or when there isn’t convenient outlet access.

Using Network Radios with Zello to Improve Workplace Communication:

Many workplaces can benefit from adopting network radios with Zello push-to-talk. In addition to the cost and dependability of these devices, they provide a dedicated "walkie talkie" for workplace communication that can be shared between shift workers, enabling seamless team communication, no matter where they are located in the world(!), so long as internet access via Wi-Fi or mobile data is available. Data usage is also very low, and no call charges are incured!.

“On a customer visit this summer, I learned that Zello deployed on network radios is completely replacing traditional two way handheld radio communications at a fraction of the cost,” said Bill Moore, Zello CEO. “These radios have really enhanced workplace productivity.

Additionally, Zello allows employers to easily configure their networks and track and archive usage via its Web-based management console.”

Network radios let users communicate on multiple Zello radio channels without the distance limitations of traditional two way radios. By adding Zello to mobile network radios, users can access the app’s extensive and established user base or opt to use the company’s private radio networks with Zello, which offer the benefits of a configuration console, map history features, and message archives, among others.

How To Get a Network Radio with Zello:

Network Radios is currently offering network radios with Zello pre-installed. Users can also install Zello on new or existing network radios including the Inrico T199 and the Talkpod N-50 (though the Talkpod N-58 is not recommended). To install, connect your network radio to your computer, sync it with an Android screen viewer (such as Vysor), then download and sign in to Zello. Vysor mirrors the device’s screen to your computer, allowing you to navigate the Android home screen and Zello UI.

The push-to-talk space is a genuine ecosystem, with services, data, and devices requiring true collaboration to deliver meaningful solutions to customers. Zello is dedicated to building relationships across the industry so more users can enjoy turnkey push-to-talk products like those offered by Network Radios.

Amateur radio related use of network radios (I use mine here too when I am not too busy)...

In case you wondered, I make reference elsewhere to my involvement in amataur radio and am also a long standing listener to the bands. This is how I got into radio to begin with. And gaining my amateur radio license in July 1995 also greatly helped me get into university later that year! You can read this story here.

And indeed there amateur raio oriented, public channels related to alateur radio. You do not need a licence to use these, but I strongly recommend spending time listening before you transmit, to get to know the proceedures and the 'do's and dont's'. Disruptive users can be blocked!

Here are the official Network Radios channels (you need to be 'trusted in' before you can participate. Before this only moderators can year you:
