Top 13 C++ rtl-sdr Projects

  • gqrx

    Software defined radio receiver powered by GNU Radio and Qt.

    • Project mention: Listen to HD radio with a $30 RTL SDR dongle | news.ycombinator.com | 2023-11-05

    There's an issue open for this: https://github.com/gqrx-sdr/gqrx/issues/1104

    I could really use some help from a software build expert. Gqrx and all its dependencies would need to be built in CI with Apple silicon support, and I don't know how to do that.

  • sdrangel

    SDR Rx/Tx software for Airspy, Airspy HF+, BladeRF, HackRF, LimeSDR, PlutoSDR, RTL-SDR, SDRplay RSP1 and FunCube

    • Project mention: SDRangel release | /r/RTLSDR | 2023-11-01

  • InfluxDB

  • CubicSDR

    Cross-Platform Software-Defined Radio Application

  • gnss-sdr

    GNSS-SDR, an open-source software-defined GNSS receiver

    • Project mention: Just scrolled past a certain sarcastic Flatwittoid poast about not beïng able to see satellites in photographs. The whole frame of this represents *one single pixel of a high resolution* image, & the smiley represents a satellite. Details inside. | /r/flatearth | 2023-05-20

    You realise you can write software yourself to interpret the signals from GPS satellites? Here's an open-source implementation.

  • wmbusmeters

    Read the wired or wireless mbus protocol to acquire utility meter readings.

    • Project mention: Residential water meter - Community feedback is welcome | /r/Esphome | 2023-05-30

    It's possible you do not even need a meter. You can often read the utilities meter https://github.com/wmbusmeters/wmbusmeters

  • RTLSDR-Airband

    Multichannel AM/NFM demodulator

    • Project mention: Listen to HD radio with a $30 RTL SDR dongle | news.ycombinator.com | 2023-11-05

    You're all correct, except there are not that many $30 SDRs out there. Also, most SDRs have clearly superior capabilities to the RTL-SDR, though those capabilities often are not required.

    BTW, for simple AM/FM demodulation I cannot recommend enough the handy https://github.com/charlie-foxtrot/RTLSDR-Airband. For example most of LiveATC.net feeds run on it.

  • rtl-sdr-scanner-cpp

    • Project mention: Rtl-sdr or sdrplay RSP1A | /r/RTLSDR | 2023-12-10

    Bonus: Check out https://github.com/shajen/rtl-sdr-scanner-cpp I've been experimenting with this and got it to work with the RSP1A it can record everything within it's allowed bandwidth and pull out / label calls... It even uses a small AI feature to differentiate between speech and noise (mileage may very). Good luck on your journey!

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • AIS-catcher

    AIS receiver for RTL SDR dongles, Airspy R2, Airspy Mini, Airspy HF+, HackRF, SDRplay and SoapySDR

  • redsea

    RDS decoder for the command line (by windytan)

  • rtl-power-fftw

    Power spectrum for RTLSDR dongles.

    • Project mention: Export near real-time trace | /r/RTLSDR | 2023-05-16

  • airspy-fmradion

    Software decoder for FM/AM broadcast radio with AirSpy R2 / Mini, Airspy HF+, and RTL-SDR

    • Project mention: Listen to HD radio with a $30 RTL SDR dongle | news.ycombinator.com | 2023-11-05

    I have a little hobby project where I record an FM radio music station using a SDR and then remove all the non-music portions for offline listening. I like the music selections the DJs pick, but I prefer not to listen to the DJ commentary and the advertisements.

    I evaluated three methods of recording: analog capture from a standalone FM receiver, using this nrsc5 library to record the "HD" radio stream, and using an AirSpy SDR with this library: https://github.com/jj1bdx/airspy-fmradion

    Recording the "HD" (what a misnomer) radio was nice in that there was no hiss or multipath effects, but in comparison to the other methods the digital compression artifacts became impossible to un-hear. It seems to top out at about 96 kbps

    The airspy-fmradion library has some nice stuff in it to address multipath, resulting in the best audio quality of the three methods I tested.

    I use https://github.com/ina-foss/inaSpeechSegmenter to identify which segments of the recordings are speech vs. music.

  • DAB-Radio

    Demodulator and decoder for DAB signals captured using RTL-SDR

  • rtlmuxer

    rtl_tcp stream splitter

    • Project mention: Use dongle for two programs | /r/ADSB | 2023-05-20
