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.

I've set off time to blog about getting my broadband RF scanner (connecting to USRP B200 via WebUSB) to work in WASM.

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.
