SI473X Library for Arduino

Build a SDR SW/MW/LW Receiver with a Raspberry Pi Pico

KiwiSDR: BeagleBone web-accessible shortwave receiver and software-defined GPS (archived)

RTL USB HTML SDR radio

Handheld AM / FM / SW receiver on ESP32-S3 and SI4732. SSTV, Morse, RSSI homing, and a web remote.

KiwiSDR: BeagleBone web-accessible shortwave receiver and software-defined GPS

A nice SDR# plugin for Short Wave (and not only!) listening enthusiasts.

A whole SDR ecosystem built for one hand: a receiver for iPhone, iPad, Mac, Android and Apple Watch with its own DSP, and VibeServer, which shares your radio from a Raspberry Pi, a Mac, a Linux box, a spare Android phone or even a television.

A WebSDR server: C++17 with no dependencies, a one-line install, and an admin panel for everything. Demo: demo.fernsdr.org

Silicon Labs SI4844 (BROADCAST ANALOG TUNING DIGITAL DISPLAY AM/FM/SW RADIO RECEIVER) Library

Si5351 and Arduino based superheterodyne receiver

Arduino Library for the AKC695X devices

The server to emulate old warm AM radio sound on Raspberry Pi

Python for ITU P.368 : Ground-wave propagation curves for frequencies between 10 kHz and 30 MHz

Auto Band Pass Filter controlled by Arduino

Si5351 based WSPR beacon

SDR transceiver for HAM and tuned with CB, Freeband and SWL in mind — CB channel plans, WSJT-CB interop, SWL mode, CW/PSK skimmers, FT8 & friends, station profiles, logbook, propagation map. Many radios (Icom,RTL-SDR, RX-888, Airspy, CAT, TCI, HPSDR, SoapySDR), native desktop + browser UI.

Cross-platform HF weather-fax (WEFAX) decoder — interoperable with KG-FAX. C++17 + FLTK + RtAudio. GPLv3+.

A Radio Logging application build with NodeJS and ExpressJS

High performance SDR band scanner - detects, demodulates, and records radio transmissions automatically with CTCSS/DCS detection, three-layer noise rejection, and broadcast-standard metadata.
