GNU Radio for Windows Subsystem for Linux

USB (non-networked) SDRs need to run GNU Radio through Windows directly, since Windows Subsystem for Linux does not currently support USB at a low level. GNU Radio can use the computer sound card to playback/record sound on Windows.

Network connected SDR

For network-connected SDR, or for running software-only simulations, here’s how to install and run the GNU Radio Companion GUI on Windows Subsystem for Linux (WSL).

  1. Install X11 for Windows Subsystem for Linux
  2. install GNU Radio in WSL Terminal

    apt install gnuradio
    1. start Xming (no window appears) and then type in WSL Terminal
    gnuradio-companion

Audio Sink

WSL1 does not accept ALSA soundcard input, so disable any Audio Sinks in your GRC diagram for WSL1.

Procedure that runs a PulseAudio connector on Windows from WSL, with local port forwarding of audio packets over a local network socket from WSL to Windows.
