Not for amateurs

PTT4U is a state-of-the-art network radio service for professionals.

Relying on the GSM signal, our radios will be able to talk to each other without any range restriction. Each radio works with a SIM card (not included) and uses GSM/3G/4G and some modes even work with WiFi signal. This means you don’t need to spend a fortune on expensive radio infra-structures, repeaters, antennas or site rentals. All the network infra-structure is provided by the GSM carrier.

Private and group calls are available. Your team members can be in different countries and still within reach. Each user can check each other’s location (based on their profile), send messages and SOS alerts.

All you need to do, is to purchase our network radios, depending on your needs, insert your preferred carrier SIM card on the radios (a monthly data plan of 500MB will be enough) and subscribe the yearly PTT4U service. You will need one yearly $49 subscription for each radio. And that’s it! No more headaches.

IRN – International Radio Network

What is the IRN?

The IRN (International Radio Network) is a VoIP/RoIP system using Teamspeak 3 (TS3) that allows radio users to TX/RX using RF around the World using  different devices (Mobile Phones, Tablets, Computers etc) for free.

The system also allows users to create private talkgroups for point to point or private group QSO’s.
If you would like to add your link, repeater or hub to the IRN system, please use the contact us section to drop us a line.
TS3 is available on Apple, Android, PC, Mac and Linux. The IRN has it’s own private server allowing hundreds of connections at once. There are different talkgroups (channels) within that allow users full RX/TX capabilities across different radio networks and systems from across the globe.
To make it more interesting, you can use PTT-enabled smartphones like the ones listed below. Most of the hams use PTT-enabled phones, so they can use the IRN with the same style as they use a handheld radio. The IRN talk groups can be accessed via GPRS / 3G / 4G / Wifi or RF (depending on the repeaters).

Is this still hamradio? Read this article.

Please note: This system is free to use for both non-licensed* & licensed hams. Live ham-radio repeaters can only be accessed by licensed hams.

*Non-licensed users must apply for membership of IRN in order to have a callsign generated for them (Don’t worry, it’s also free).

The following devices have a dedicated PTT button that will make your experience even better when using the IRN.

Please click on the link below to download the PDF file for your device.

These PDF files can be downloaded so that you can set up your device with the IRN server details.

Please note, that once you have signed into the server, an admin will tag you and ask you to register on our MemberPlanet User Database.  Once verification is complete you will be given talk rights based on your license status.  Unlicensed operators do not have talk rights on any amateur radio links.

In case of any issues, we will contact you via email (please supply one directly if you do not have one listed on QRZ).

PLEASE TAKE THE TIME TO READ EACH STEP OF THE INSTRUCTIONS. 

PLEASE ENSURE THAT YOU ARE NOT IN VOX MODE ON YOUR DEVICE WHEN YOU CONNECT.
