Casio G-Shock time sync radio

Thanks for those references! I wanted to see what an SDR radio time signal detector would look like, and looking for "DCF77 sdr python" pointed me in the right direction -> [0] and [1]

A bit unrelated question: there are many web SDRs that let you listen to radio frequencies/stations such as [2]. Are there web / Emscripten SDR decoders that run in-browser? i.e. a full browser listening + decoding experience? For example, decoding a DCF77 time signal, or even just morse code?

Amazing, exactly what I was looking for! I've had luck on http://carinthia.proxy.kiwisdr.com:8073/ (the link you posted seems busy right now)

I was able to use the FSK decoder, it worked really well. For those curious, the C-based decoder extensions are here [0]
