Ben's notes

QRSS with Raspberry Pi, SDRplay RSPdx and Leo Bodnar GPSDO.

Note: Using GQRX and RSPdx, use filter bandwidths: 0.2, 0.3, 0.6, 1.536, 5, 6, 7, 8 MHz

• Raspberry Pi 4
• Pi 4 Power supply
• SDRplay RSPdx
• Leo Bodnar GPSDO
• Micro SD Card
• Antenna
• Cables

• Install Pi OS
• Update OS
• Install required packages

  apt install python3-pip git cmake g++ libpython3-dev python3-numpy swig libavahi-client-dev uhubctl python3-venv

• Disable WiFi, BT
• Download and install SDRplay API 3.07 (for 64bit OS)

  bash SDRplay_RSP_API-ARM64-3.07.1.run

• Install SoapySDR

  mkdir git
  cd git
  git clone https://github.com/pothosware/SoapySDR.git
  cd SoapySDR
  
  mkdir build
  cd build
  cmake ..
  make -j4
  sudo make install
  sudo ldconfig
  
  SoapySDRUtil --info

• Build SoapySDR SDRplay module

  cd ~/git
  git clone https://github.com/pothosware/SoapySDRPlay.git
  cd SoapySDRPlay
  
  mkdir build
  cd build
  cmake ..
  make
  sudo make install
  
  SoapySDRUtil --probe="driver=sdrplay"

• Install SoapySDR remote for tuning antenna with SDR GUI on client

  cd ~/git
  git clone https://github.com/pothosware/SoapyRemote.git
  
  cd SoapyRemote
  mkdir build
  cd build
  cmake ..
  make
  sudo make install
  
  sudo systemctl enable --now SoapySDRServer

• GQRX should discovery the remote SoapySDR server
• Install GPS utility

  sudo apt install libhidapi-hidraw0 libhidapi-libusb0
  cd ~/git
  git clone https://github.com/hamarituc/lbgpsdo.git
  cd lbgpsdo
  python3 -m venv venv
  . venv/bin/activate
  pip install -r requirements.txt
  sudo cp 99-lbgpsdo.rules /etc/udev/rules.d/
  sudo groupadd usb
  sudo usermod -aG usb user
  reboot

• Install rx_tools

  cd ~/git
  git clone https://github.com/rxseger/rx_tools
  cmake .
  make

• Example running rx_sdr and qrsspig

  /home/user/git/rx_tools/rx_sdr \
          -s 62500 \
          -f 3568600 \
          -d driver='sdrplay' \
          -a 'Antenna C' \
          -F CS16 - | qrsspig --configfile /etc/qrsspig/qrsspig-pipe-80m.yaml
