    Oh that's cool!I've set off time to blog about getting my broadband RF scanner (connecting to USRP B200 via WebUSB) to work in WASM.https://rf-survey.habets.se/It's basically https://blog.habets.se/2026/08/Broadband-RF-scanner-revisite..., but in the browser.I also have an AX.25 decoder (https://thomashabets.github.io/ruwasm/) and plain old FM receiver (https://cement.retrofitta.se/tmp/rtlsdr-fm/) already. The latter two work with RTL-SDR, also via WebUSB, so no software installs or setup required.I've been meaning to make a "GNU Radio in the Browser" (well, gnuradio-companion-like) for my RustRadio project to build flowgraphs without coding, but not gotten to it yet.

    No idea what I'm looking at, it's just combining some noise and a sawtooth wave to create pretty visuals I guess? if this is meant to serve as an introduction to the project it's not really succeeding. The "Description" isn't even readable despite most of the page being used for empty space. I guess it's expected to have no audio output? I presume the real purpose of this is to process signals from an actual radio?The "Help"->"Help" menu item is notably unhelpful:> For questions, comments, or suggestions, you can email support@gnuradioworld.com, join the Discord server, or post a GitHub issue."Help"->"About" at least starts to clarify some things:> GNU Radio, entirely in your browser — explore the open-source SDR ecosystem with zero install!> GNU Radio World is a browser-based GNU Radio Companion flowgraph editor and WebAssembly runtime. You can place, connect, and configure blocks, then run the resulting flowgraph directly in your browser.> It is designed to download only the WebAssembly modules corresponding to the blocks you use. This on-demand architecture keeps the initial download small and can support a limitless collection of out-of-tree modules (OOTs) in the future.> GNU Radio World also includes a collection of real RF recordings that are downloaded only when you use them. You can inspect the recordings in the built-in recording view, adapted from IQEngine, and use them in the included flowgraph examples, allowing OOTs to be shown off with real recordings of the corresponding signals

    I tinkered with gnuradio back when rtl-sdr just took off (2012ish?).I had no background in dsp or signal processing and found it so opaque as to be unusuable, even though I saw more skilled folks do amazing things with it.*scratches head*Might give it another go.

    This is so cool! Congrats!

    That’s amazing, thanks for the share! I did a small test, it works, screen is a bit harder to navigate on small screens but not an issue.
