Configuring your SVXLink node
Once SVXLink has been installed on your Raspberry Pi, or Debian host you can go ahead and configure it. I’d recommend using a tool such as WINSCP to connect to your host to make editing files easy.
- Download the following svxlink.conf template file to your PC and open it in notepad: svxlink.conf template file
- Edit the following sections highlighted in red below with your details
To enter your LAT/LONG in the config file, use google maps to find your LAT/LONG and then use the following calculator to convert your LAT/LONG to Degrees Minutes Seconds (6 digits in total): LAT LONG Calculator

3. Once your file is updated, save it and copy it to /etc/svxlink/ and overwrite the existing svxlink.conf file
At this point, you’re probably excited to see if you can start svxlink! But, if you do so at this point, you’ll receive a bunch of errors. That’s because you need to connect your radio via your FTDI cable and soundcard first.
In the next part of this guide, you’ll learn how to connect the radio to your Pi.
