gqrx
Gqrx is a free, open-source software-defined radio (SDR) receiver application that works with a range of radio hardware including RTL-SDR dongles, Funcube Dongles, USRPs, and Osmo SDR devices. It is powered by GNU Radio and uses the Qt5 GUI toolkit. Gqrx is widely used by radio enthusiasts, hobbyists, researchers, and engineers for receiving and analysing radio signals across various frequencies. Users can tune frequencies, apply filters, decode various modulation schemes, and export received data for further analysis.

1 suggestionGqrx is open-source software maintained on GitHub and distributed through package managers like MacPorts. To confirm the current status of Apple Silicon support, check the official Gqrx GitHub repository (github.com/csete/gqrx) for recent release notes and architecture information. If you have installed Gqrx via MacPorts, run sudo port upgrade gqrx to pull the latest version — MacPorts will automatically select the appropriate architecture for your Mac. If the latest MacPorts build is still Intel-only, you can try building from source using the GitHub repository, which may include Apple Silicon support even if the packaged version has not caught up. Given that we are approaching September 2028 when Apple removes Rosetta 2 support, it is worth checking directly with the Gqrx maintainers or the MacPorts community to understand whether a native build is in progress or already available.
