For hardware, you need to have the following:
- Raspberry Pi for sure, with a minimum 4GB SD card
- A USB echolink interface, can be commercially sourced or DIY. There are many DIY schematics out there that you could follow.
- Here is the configuration on how to get the things working together, courtesy of svxlink.de website:
- Download the following prepared image from google drive, it is based on raspbian-2015-02-16 image and has pre-installed svxlink-14.08. raspi-wheezy-svxlink.img.zip
- Unzip the file and copy it to your SD card using the following instructions that can be found here.
- Boot up the RasPi, if you do not have an HDMI monitor, you may want to access the RasPi from your terminal emulator (putty or the like), connect the RasPi to your router via CAT5 cable.
- To find the IP address of your RasPi, just go to your router status and look for the hostname raspberrypi.
- Use SSH connection, logon to the RasPi using the default username/password which should be: pi/raspberry
- If you've bigger SD card then the 4GB image, you may want to use fullest capacity of the SD card, run the raspi-config command as sudo:
- $ sudo raspi-config
- Choose the first option to expand rootfs. Exit when done.
- $ sudo nano /etc/svxlink/svxlink.d/ModuleEchoLink.conf (edit the callsign - use sysop -L callsign, password, sysop, location and description)
- $ sudo nano /etc/svxlink/svxlink.conf (edit the callsign), if you're using echolink interface that uses VOX, just leave the others as is. Edit the APRS info too as required.
- $ sudo alsamixer (use the up/arrow to tune the volume, right/left to move between speaker and mic sliders).
- If the slider has MM underneath them, it means that they're muted, press 'M' to unmute.
- $ sudo svxlink
- $ update-rc.d svxlink defaults
