gr-fosphor has been an invaluable tool for debugging physical layers and enjoying the experience of exploring the EM spectrum.
Too many times I found myself or others trying to use it in a new setup or in a fast-paced OS (like Arch Linux) just to find it is broken, hard to install/repair or uninstallable for some hard to debug reason. With that in mind, I made a Dockerfile [1] for building an image for launching a containerized gnuradio-companion with a ready-to-go basic "ZMQ SUB source --> QT fosphor sink" flowgraph, so you can send samples from the outside. Hope it helps. Comments are welcome. [1]https://github.com/franalbani/docksphor
