====== Svxlink & Echolink ======

** Revisiting the Analogue FM Voice Gateway**

=====  Svxlink Gateway Initial Setup =====

==== Trying not to re-invent the wheel ====

  * find saved Pi Image File for a previous Svxlink system
  * copy to a new SD Card and boot a spare Raspberry Pi with it
  * find and connect a modified CM108 sound-dongle - has PTT and SQL via the dongle's own GPIO
  * connect to 2m FM radio and test initial config
  * make any necessary config changes - e.g. MB7AZE -> GM4SLV
  * set up audio levels using //devcal//
  * change to //9600 packet interface// on 2m radio to remove radio pre/de emphasis and apply pre/de emphasis in Svxlink
  * set up audio levels again using //devcal//
  * Check connectivity to Echolink
    * remember to Port Forward on ADSL router : **UDP 5198 & 5199** -> svxlink Pi's IP address
    * consider using a private proxy on my VPS instead? [[public:radio:topics:jre_echolink|]]

==== Pi Image File handling ====

[[public:computers:rpi_image|]]

==== Devcal ====


  * [[public:radio:dormant:mb7azeconf#devcal|]]
  * remember to ''sudo killall svxlink'' to ensure no daemon svxlink processes are running in the background
  * remember to adjust path to valid //svxlink.conf// file which will be different to this old example
  * Set for 3kHz deviation
  * remember to edit the config file(s) to change the RX Pre-amp and TX Master Gain settings to match those find using Deval

<code bash>
sudo devcal -r -m=3000 -d=3000 /etc/svxlink/svxlink_noel.conf Rx1
</code>

<code bash>
sudo devcal -t -m=3000 -d=3000 /etc/svxlink/svxlink_noel.conf Tx1
</code>

  * add the PRE_AMP and MASTER_GAIN settings to **both** ''svxlink_el.conf'' and ''svxlink_noel.conf'' 
==== Config Files ====

  * One for **Echolink Enabled** 
  * One for **Echolink Disabled**
  * Switch Echolink on/off via DTMF commands
    * Edit **Logic.tcl** to give this functionality

==== Catch up with git version ====

  * The version of svxlink running on this Pi was self-compiled from the GIT repository
    * [[public:radio:dormant:svxlink#Update to latest version from GIT|]]
  * I decided to pull & compile the latest version so I simply followed the instructions I'd put on the above wiki page and all went smoothly (if slowly)


==== DTMF Commands ====

   * Old info [[public:radio:dormant:svxreflector_commands|]]
   * Ignore **Reflector** commands - I am not (yet) connected to the SVX Reflector [[http://svxportal-uk.ddns.net:81/index.php]]

|''D3#''|Echolink |662666 |M0JKT-L | FreeStar |


==== Sound files ====

  * use ''en_US'' when **echolink is enabled**
    * this is also needed for **reflector** when it's re-enabled, as the ''US'' files also have the additional reflector sound samples
  * use ''en_GB'' when **echolink is disable**
  * easy to tell from status ''*#'' which is active!



==== Proxy ====

  * after consideration....
  * I decided to use my VPS-hosted echolink proxy
    * remove port forwards on home router for UDP/5198 & UDP/5199
    * open port TPC/8100 for **only my home IP address** on VPS
      * this means only one IP address can reach the Proxy on port TCP/8100
    * open ports UDP/5198 & UDP/5199 for anywhere on VPS
    * edit echolink proxy config on VPS to allow only GM4SLV-L to connect
      * this means only one callsign can connect to the proxy
    * start proxy in a tmux session, using bash script on VPS
    * edit ModuleEchoLink.conf on svxlink pi to use the proxy
    * restart ''svx_el.sh''

<code bash>
PROXY_SERVER=my.vps.host.name
PROXY_PORT=8100
PROXY_PASSWORD=xxxxxxxxx
