Pi for Echolink on an RLC-3 Controller - Part 2 - SVXLink Install

My ham radio club would like to to add Echolink functionality to our repeaters.  In part 1 I did a basic Raspberry Pi setup.  In this version I will attempt to install the Echolink software.

Installing SVXLink

I have read several versions of instructions to trade off complexity vs functionality.

• The Svxlink site has a really complicated version if you are one of those people who likes to compile yourself and make a bunch of optimizations to your Pi.   I started down this path, but I felt it was terrifically more complex than I needed.
• The next version I tried, and made significant progress on was this one by KN4ADN.  It has some localization that people might find helpful.   
• The one I ended up using is the version from the Svxlink site that installs a binary.  Finish the testing and you should hear something like this.

Success on getting the audio to play through a soundcard.  Now I will need to make a change to get it to use the Signalink for Audio Output.   Luckily, that's an easy change.  Editing in the same config file you did before:

 sudo nano /etc/svxlink/svxlink.conf  

Go to the [TX1] section and change the configuration for AUDIO_DEV to this:

 [Tx1]  
 TYPE=Local
 AUDIO_DEV=alsa:plughw:1
 AUDIO_CHANNEL=0

Exit out, connect your speaker to the MON port on the SignaLink.   Now start SVXlink again and run the *# command.  You should hear the relay click on the SignaLink and the audio clip play.

It's a good time to make a backup of your SD card again, because the next step will be to do deeper configuration of the software and wire the Signalink for the RLC-3.
