Re: GNU Radio in the browser
#2I 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.

I've tinkered with SDR some and did a bit professionally. I always found GNU Radio to fall into the uncanny valley - too GUI to scratch my programming itch but too low-level to be useful for exploration. Between libraries like `pyrtlsdr` and desktop apps like `sdrangel`, I can't seem to find a niche for GNU Radio.

#4Oh 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.
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.

Run through pysdr[0], which I found has the right complexity gradient and the right levels of abstraction for people with technical chops but who aren’t familiar with SDR

#6That’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.

I worked with GNU Radio quite a bit at one point a decade+ ago, even writing a custom C++ block, but I almost exclusively used it via Python rather than the GUI toolkit. I found it much quicker to mess around with flow graphs in code than their various UI frameworks, spawning windows as needed when plotting waveforms / spectra etc. The GUI as you said was too cumbersome.
I understand that they were trying to make a pretty complicated topic more approachable, but I always felt the push to GUI was misguided. Maybe they would have had more luck embracing the “S” in “SDR” and making programming languages the primary development paradigm.

#8Cool. On github forked and starred. Thank you.

I have to say having just done a very tricky project with a long DSP pipeline in gnuradio, that LLMs are a godsend for getting up to speed on gnuradio blocks. I too found it historically impenetrable, but was able to get a pipeline completed. That said, prepare yourself for a lot of debugging and work to diagnose problems if you’re doing anything of sufficient complexity.

New textbook may help
