FoxSDR: A From-Scratch Software-Defined Radio Receiver for Windows

Thank you to an anonymous contributor (known only as wonderingStars on GitHub) for writing and sharing their project, 'FoxSDR'. FoxSDR is advertised as a 'software-defined radio receiver written from scratch'. Like most receiver programs, it includes a spectrum and waterfall and various demodulation modes.

Key features include a Windows desktop application and optional browser-based interface, a built-in ADS-B decoder and map, and native support for drivers for the HackRF, Airspy R2/Mini/HF+, RTL-SDR, SDRplay RSPs, Mirics MSi2500, RX888 mk2 and the ALDAMN-Pluto. Being browser-based means that the server can run remotely and be placed close to the antenna to reduce signal losses, and the SDR can be accessed from any networked device. They have also recently added AIS, APRS, SSTV, Morse, RTTY, POCSAG, Inmarsat-C, ACARS, SSTV, NOAA APT, GOES HRIT/LRIT, WEFAX, two-tone paging, EAS/SAME alerts, 406 MHz distress beacons, VOR, ERT utility meters, 433 MHz weather sensors, a satellite pass predictor and map, a band survey engine, and OpenStreetMap map imagery.

The contributor writes that FoxSDR is currently Windows-only; however, they will add full Linux support once the Windows version is completely stable. They note that they are in the final stages of the beta and that, based on telemetry, they have over 100 installs in the last month and a few dozen people using it on any given day. They note that their three-year development plan includes support for all operating systems, including Android.
