Echolink and WSPR node based on a Raspberry PI

Requirements

• Raspberry PI (model doesn't matter)
• Raspbian 9 installed and working
• Internet access setup and working

Required setup and software

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install g++ make libsigc++-1.2-dev libgsm1-dev libpopt-dev tcl8.5-dev libgcrypt-dev libspeex-dev libasound2-dev alsa-utils libqt4-dev
sudo apt-get install libsigc++ cmake groff 

Echolink (Thru SVXLink)

sudo adduser svxlink
wget https://github.com/sm0svx/svxlink/archive/master.tar.gz
tar xvzf master.tar.gz
cd svxlink-master/src
mkdir build && cd build
sudo cmake -DCMAKE_INSTALL_PREFIX=/usr -DSYSCONF_INSTALL_DIR=/etc       -DLOCAL_STATE_DIR=/var -DUSE_QT=NO ..
make
make doc
sudo make install
sudo ldconfig

• Copy the etc/svxlink folder to your /etc/svxlink foder.

sudo cp -r etc/svxlink/* /etc/svxlink/

• Edit callsign and password (from Echolink Link/Repeater setup).
• Edit description.
• Check GPIO ports for Squelch and PTT.

GPIO Setup

• Copy the etc/rc.local file to your /etc/rc.local

sudo cp etc/rc.local /etc/rc.local

• Check and match GPIO ports for Squelch and PTT.
• For SVXLink autostart:

sudo cp opt/svx.sh /opt/svx.sh
sudo chmod +x /opt/svx.sh

• Add @lxterminal -l -e "/opt/svx.sh" BEFORE xscreensaver line on .config/lxsession/LXDE-pi/autostart

Software reset

• There is a Python script that handles Raspberry PI reboots from a hardware switch without killing power.
• Check the /etc/rc.local file and match the desired GPIO port for this task.
• Copy lib/systemd/system/reset.service to /lib/systemd/system/reset.service

sudo cp opt/reset.py /opt/reset.py
sudo cp lib/systemd/system/reset.service to /lib/systemd/system/reset.service
chmod 644 /lib/systemd/system/reset.service
systemctl enable reset.service
systemctl start reset.service

WSPR

git clone https://github.com/JamesP6000/WsprryPi.git
cd WsprryPi/
make
sudo make install
sudo wspr --test-tone 780e3

• Check if you hear the continuous test tone on 780Hz.
• Add to your .bashrc file: alias wspr='sudo wspr -r your-callsign your-grid-locator 10 20m'

echo "alias wspr='sudo wspr -r your-callsign your-grid-locator 10 20m'" >> .bashrc
