GNU Radio

GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic and commercial environments to support both wireless communications research and real-world radio systems.

Packages

The latest stable GNU Radio version can be installed with gnuradio from the official repositories.

Bleeding edge is gnuradio-git^AUR in the AUR, and in some cases VOLK may need to be built separately from libvolk-git^AUR.

If you want gnuradio-companion, just install the gnuradio-companion package which will install GNU Radio, as well as some additional required packages.

Another popular package is gnuradio-osmosdr which provides the GRC source blocks for many of the popular SDR devices (Funcube Dongle, RTL-SDR, USRP, OsmoSDR, BladeRF and HackRF).

Troubleshooting

TypeError: in method 'source_sptr_set_gain_mode', argument 2 of type 'bool'

When using an (osmocom) RTL-SDR source, you might see this error. The workaround is to manually set the Gain Mode to True or False.
