This is the install process for setting up a Flight Radar 24 ADS-B feed using a raspberry PI (V4) and a SDR-Blog VR Dongle. It also includes the install and mechanism to switch to an SDR++ server to allow remote clients to attach and listen to ATC audio remotely.
Using the PI imager software, you should image the PI and when prompted to select the image you need to select: Raspberry PI OS (Other) –> Raspberry PI-OS (Legacy 32-bit) Lite
It is important you choose the 32 bit version, and choosing the Lite version means we get a Headless install without all the bloat.
You should also select any other customizations, you should select and enable SSH at least / WI-Fi and other settings.
After flashing the PI allow it to boot and connect to the network, you can then ssh to it (ssh account@hostname) Login and update the PI to the latest OS.
sudo apt update sudo apt upgrade sudo apt dist-upgrade sudo reboot
The next step is to install the V4 Debian Drivers for the SDR-Blog VR USB Dongle
You must run this as a user, not as root, (only sudo on the commands specified below.)
sudo apt purge ^librtlsdr sudo rm -rvf /usr/lib/librtlsdr* /usr/include/rtl-sdr* /usr/local/lib/librtlsdr* /usr/local/include/rtl-sdr* /usr/local/include/rtl_* /usr/local/bin/rtl_*
sudo apt-get install libusb-1.0-0-dev git cmake pkg-config mkdir /opt/sdr cd /opt/sdr git clone https://github.com/rtlsdrblog/rtl-sdr-blog cd rtl-sdr-blog mkdir build cd build cmake ../ -DINSTALL_UDEV_RULES=ON make sudo make install sudo cp ../rtl-sdr.rules /etc/udev/rules.d/ sudo ldconfig
echo 'blacklist dvb_usb_rtl28xxu' | sudo tee --append /etc/modprobe.d/blacklist-dvb_usb_rtl28xxu.conf
sudo reboot
sudo wget -qO- https://fr24.com/install.sh | sudo bash -s
This will run the script and start the setup questions. After you have answered these, you will need to run this command to allow the new fr24 user access to the USB dongle, otherwise you will get errors in the log and no data.
adduser fr24 plugdev
sudo systemctl restart fr24feed fr24feed-status
