Requires compatible SDR hardware such as RTL-SDR or HackRF and Qt5 libraries, all documentation lives on the project Wiki, not in the README.
SDRangel is an open-source application for working with software-defined radio hardware. SDR (software-defined radio) moves the signal processing that would traditionally be done by dedicated electronics into software running on an ordinary computer, so the same physical USB dongle or device can tune to many different frequency ranges and decode many types of signals depending on what software is handling the data. The application provides a graphical interface built with Qt5 and uses OpenGL for rendering. It supports a range of popular SDR hardware devices, including Airspy, Airspy HF+, BladeRF, HackRF, LimeSDR, PlutoSDR, RTL-SDR, SDRplay, and FunCube. The repository topics indicate it handles digital radio protocols such as DMR (Digital Mobile Radio), D-STAR, and DPMR, which appear in both amateur and commercial radio contexts. The software supports both receiving and transmitting signals, depending on which hardware you have connected. The README itself is brief and directs users to the project Wiki for documentation and setup guidance. The developers recommend reading at least the Home and Quick Start pages before running the program for the first time. A community discussion group is also available for questions and help from other users who run the software. Two companion projects extend SDRangel in different directions. SDRangelcli is a web application that can control a headless (no graphical interface) instance of SDRangel running on a server, or serve as a remote control panel for the regular GUI version running on another machine. SDRangel-Docker provides Docker files and scripts for building and running SDRangel in a container, supporting both the graphical and server-only modes.
SDRangel is a desktop application that lets you receive and transmit radio signals on a wide range of frequencies using popular USB software-defined radio hardware and a graphical interface.
Mainly C++. The stack also includes C++, Qt5, OpenGL.
Open-source, specific license not detailed in the explanation but the project is freely available.
Setup difficulty is rated hard, with roughly 1h+ to a first successful run.
Mainly developer.
