Gqrx
Gqrx is an open-source software-defined radio (SDR) receiver application powered by GNU Radio and the Qt graphical toolkit. It lets amateur radio enthusiasts, signal engineers, and hobbyists tune into and analyze radio frequencies across a wide spectrum using compatible SDR hardware such as RTL-SDR dongles, Airspy, and other devices. The app displays real-time frequency spectrum views, waterfall graphs, and signal demodulation controls, making it accessible for both receiving broadcasts and experimenting with radio signals. Gqrx runs primarily on Linux and macOS and is actively maintained by the open-source community.

1 suggestionGqrx is actively maintained open-source software with regular updates published on GitHub. The most recent release (version 2.17.5, from late 2024) was built using an updated GNU Radio stack and expanded hardware support. Check the official Gqrx download page or your macOS package manager (Homebrew or MacPorts) to ensure you have the latest build. The GitHub releases page shows recent activity, so watch for new versions that may include native Apple Silicon optimizations. If you are currently running an older Intel-only build under Rosetta, updating through your preferred package manager should pull in a more recent binary; if a native arm64 build is not yet available, the developer is actively working on the project and may release one in the future.
