  • RPI3b+ & RTL-SDRv4 Not functioning

    I am fairly new to all of this, so I apologize if I've missed something obvious.

    I have a Raspberry Pi 3b+ with a new RTL-SDR V4 receiver attached to an antenna that is up about 15 ft in the air outside my house. I *thought* I had this all setup correctly, but I'm not receiving any data from any planes that I've seen on FR24 fly directly over my house. I installed RTL-SDR on my Windows computer and got it to work with the AirSpy software. I was able to hear several radio feeds from across the spectrum, so I'm pretty sure my antenna setup is functional.

    When I hit IP:8754 for the status I see:
    FR24 Link: Connected via UDP
    FR24 Radar Code: #-#####
    Local IP(s):, fe80::9521:2ca6:aac8:9ae7
    Aircraft Tracked:
    (ModeS, ADS-B, UAT)
    Aircraft Uploaded: 0
    Receiver: dvbt, Connected
    MLAT running: NO
    However, if I run fr24feed-status from an SSH console I see:

    ​pi@pi24-bookworm:~ $ fr24feed-status
    FR24 Feeder/Decoder Process: running.
    FR24 Stats Timestamp: 2024-01-27 19:17:57.
    FR24 Link: connected [UDP].
    FR24 Radar: #-#####.
    FR24 Tracked AC: 0.
    Receiver: down ... failed!
    FR24 MLAT: not running ... failed!

    I did update the drivers for FlightRadar24 as explained here RTL-SDR Blog V4 Users Guide

    The issue is caused by not installing the correct custom driver required for V4 dongle

    There are multiple choices/method on the RTL SDR Blog V4 Guide. This results in many people using wrong method/option.

    The method which matches with Raspberry Pi OS (Which is reliant on Debian packages) and makes V4 to work OK is as follows:

    Alternative Debian Package Installation Method
    If you have a system reliant on the Debian packages (eg. FlightRadar24, FlightAware, ADSBExchange, OpenWebRX+ images) you can update them directly using this method:

    sudo apt update  
    sudo apt install -y libusb-1.0-0-dev git cmake debhelper
    git clone  
    cd rtl-sdr-blog  
    sudo dpkg-buildpackage -b --no-sign
    cd ../
    sudo dpkg -i librtlsdr0_*.deb
    sudo dpkg -i librtlsdr-dev_*.deb
    sudo dpkg -i rtl-sdr_*.deb  

    After completing above, REBOOT your RPi.
