-====== Svx Mobile ======
-=== Plan... ===
-To make a mobile hotspot that will provide access to SVXReflector and Echolink as well as a handy single-frequency parrot repeater.
-===== Hardware =====
-Remains the same as the previous portable hotspot
-  * Raspberry Pi
-  * CM108 soundcard
-  * IC-2E
-  * MiFi router
-It will be installed in my vehicle, which also has a TM-D710 for APRS and voice comms.
-  * <todo>Add 5V regulator to power R.Pi from 12VDC</todo>
-  * <todo>Put everything in a grab-box for portability</todo>
-==== SVXLink Config ====
-  * Echolink Module enabled (switchable via DTMF commands)
-  * Echolink using a [[public:linux:jave_jre|Private Proxy]] running on my VPS machine to enable incoming connections.
-=== Logic.tcl additions for switching EL on/off ===
-Added to ''<...>/events.d/local/Logic.tcl''
-<code tcl>
- # Example: Custom command executed when DTMF 97 is received
-  if {$cmd == "97"} {
-    puts "Executing external command"
-    playMsg "Core" "online"
-    exec /home/gm4slv/svx_ref_el.sh &
-    return 1
-  }
-  # Example: Custom command executed when DTMF 98 is received
-  if {$cmd == "98"} {
-    puts "Executing external command"
-    playMsg "Core" "online"
-    exec /home/gm4slv/svx_ref_noel.sh &
-    return 1
-  }
-  # Example: Custom command executed when DTMF 99 is received
-  if {$cmd == "99"} {
-    puts "Executing external command"
-    playMsg "Core" "online"
-    exec /home/gm4slv/svx_noref_el.sh &
-    return 1

-  * DTMF command ''97#'' will cause svxlink to restart with **Reflector** connected, **Echolink** connected.
-  * DTMF command ''98#'' will cause svxlink to restart with **Reflector** connected, **Echolink** disabled.
-  * DTMF command ''99#'' will cause svxlink to restart with **Reflector** disabled, **Echolink** connected.
-=== Start with Reflector ON and Echolink ON ===

-It's probable that I'll configure the initial start ''@reboot'' to be //with// Reflector **and** Echolink
-''crontab''  ->  ''@reboot sleep 30 && sudo -u gm4slv /home/gm4slv/svx_ref_el.sh >/dev/null 2>&1''
-Using a PROXY server for connecting to Echolink, and be able to accept incoming Echolink connections, is necessary because it's not possible to control external firewall/port forwarding when using the MiFi 4G router for internet access.
-Connecting ''direct'' to Echolink, without the ''proxy'' still allows outgoing Echolink connections to be made
-Rather than relying on other ''PUBLIC'' Echolink proxies I though it would be wise to install and run a proxy server myself, on the VPS machine. It turned out to be easier than I thought and the basic steps are [[public:linux:jave_jre| here]]
-=== Parrot ===
-I imagine being able to use the Parrot feature as a temporary single-frequency repeater perhaps for emergency use?
-I'll experiment....
