What is GNU Radio World?

GNU Radio, entirely in your browser — explore the open-source SDR ecosystem with zero install!

  • Includes popular out-of-tree modules (OOTs)
  • Many example flowgraphs — browse them at gnuradioworld.com/examples, each one runnable right on its page
  • Example IQ recordings of signals to test them with
  • Support for RTL-SDR, PlutoSDR, HackRF
  • On-demand fetching of WebAssembly modules and IQ recordings, to keep the load time short
  • Identical .grc flowgraph files as the native version
  • Share flowgraphs you create entirely via URL
  • Submit your own example flowgraphs and recordings
  • QT GUI Hints are replaced with a web-style live window arrangement, using a live miniature in the canvas
  • Embedded Python Block using Pyodide
  • Embed flowgraphs and the GUI view in other webpages (PySDR example)

Limitations

  • No Python runtime in the browser at the moment, Python-only blocks and hier blocks need a C++ implementation, Pyodide is only used for Embedded Python Blocks -Embedded Python Blocks do not yet support message handling or stream tags
  • Parameter expressions support a Python subset (arithmetic, lists, math/numpy, and common firdes filter designers) but not any arbitrary Python
