Dual 1090 978 setup

Assign a serial to the SDRs

sudo apt install rtl-sdr

Unplug non 978 SDRs and use this command: sudo rtl_eeprom -s 978

Unplug non 1090 SDRs and use this command: sudo rtl_eeprom -s 1090

Unplug both SDRs, plug them back in again to make the system aware of the new serials. A reboot will not do that.

Reconfigure readsb / dump1090-fa to use serial 1090

  • for readsb:
sudo sed -i -e 's/--device 0/--device 1090/' /etc/default/readsb
sudo systemctl restart readsb
  • for dump1090-fa:
sudo sed -i -e 's/--device 0/--device 1090/' /etc/default/dump1090-fa
sudo systemctl restart dump1090-fa

Install dump978-fa


wget -O /tmp/piaware-repo.deb https://flightaware.com/adsb/piaware/files/packages/pool/piaware/f/flightaware-apt-repository/flightaware-apt-repository_1.2_all.deb
sudo apt purge -y piaware-repository &>/dev/null
sudo rm -f /etc/apt/sources.list.d/piaware-*.list
sudo dpkg -i /tmp/piaware-repo.deb
sudo apt update
sudo apt install -y dump978-fa soapysdr-module-rtlsdr
sudo sed -i -e 's/RECEIVER_OPTIONS.*/RECEIVER_OPTIONS="--sdr-gain 43.9 --sdr driver=rtlsdr,serial=978 --format CS8"/' /etc/default/dump978-fa
sudo systemctl restart dump978-fa

Add UAT traffic to readsb / tar1090

sudo sed -i -e 's/NET_OPTIONS="--net /NET_OPTIONS="--net-connector 127.0.0.1,30978,uat_in --net /' /etc/default/readsb

As an alternative for combined 1090/978 traffic (only affects webinterface) https://github.com/wiedehopf/tar1090#configuration-optional

graphs1090

graphs1090 should add 4 978 graphs at the bottom of the page: https://github.com/wiedehopf/graphs1090#graphs1090

You'll need to set the location in /etc/default/skyaware978 so that the range graph works (--lat 50.1234 --lon 20.4567)

If the graphs don't show, try rerunning the graphs1090 install (no uninstall necessary).
