The Project

The original project was created for the Raspberry Pi B. I looked high and low for a Raspberry Pi 3 image, but none were to be found. Using the instructions on GitHub, I created one for the masses. You can find the original instructions here

The Project

The main premis of this project was to make the package as small as possible but still offer enough power. The image file is already setup to use the USB sound card as the default sound device, ssh is already active and the gpio is already configured. Login with standard pi credentials, user is pi and password is raspberry

To get up and running quickly, burn the image to an SD card of at least 4 gigs or better. Boot your raspberry pi, log in via ssh or console. Run Raspi-Config and expand the files system. Reboot. Log back in and edit /etc/svxlink/svxlink.d/ModuleEcholink.conf and change the CALLSIGN, PASSWORD and SYSOP for your echolink account. Edit /etc/svxlink/svxlink.conf and change the CALLSIGN. When dont editing, execute svxlink Enjoy.
