Welcome to VK Tetra – the home of Amateur TETRA radio in Australia.

I’m Craig – VK2CJC. I built Australia’s first amateur radio Tetra gateway, and have since been working with fellow amateurs to expand the network of Tetra gateways and repeaters in Australia.

The VK Tetra network is an amateur radio network of linked Tetra gateways and repeaters. The network allows you to use commercial grade Tetra radios such as the Motorola MTH800, MTM800e or Sepura STP or SRG range of radios to talk to other armatures both here in Australia, and overseas.

Take a look at the current gateway map to see if an existing gateway already exists near you, or why not build your own gateway by following the Build your own gateway guide.

Lewys’s gate

way has been relocated to Olympic Park, NSW and is now providing excellent coverage across North, South, West and parts of Eastern Sydney.

There are plans to install a Tetra Repeater at this location, which would provide Tetra portable to portable coverage over a large area of Sydney.

We’re rapidly approaching the end of the Year!

Recent additions to the VK Tetra network include linking the Australian DMR (Brandmeister), P25 and Analogue talkgroup 50525, which is accessible from Tetra on TG 505902.

We’ve also added a Belgium link, which is accessible via Tetra TG 206.

I still have a few MTM800e’s left if you’re thinking of building your own gateway and joining in on the fun! Check out the Radios for sale page for details.

I’ve also updated the build your own gateway instructions to link to the Github repository that contains the most up to date details on installing SVXLink on Debian. Of course, i’d recommend running your SVXLink node on a Raspberry Pi where possible, but it’s always nice to have the option!

The VK Tetra Forum is there if you get stuck too.

About TETRA Radio

TETRA radio is similar to P25 and DMR in that it is a digital mode that utilises 4 timeslots per channel. TETRA offers a range of services on top of the usual push to talk, including SMS, private calling, PSTN calling, APRS integration and more.
