Help and resources on OOK decoding
I've done it a couple different ways, but there are likely better methods that I'm not aware of though. You can get the magnitude, use a threshold block, throw away 1 in every N samples so it aligns with the bit rate, tag the start of the message with a correlate access code block if it always has a preamble, and then build a decoder block to check for the tag and work with so many samples after that. See the decode flow graph for this: https://github.com/cpoore1/gr-X10

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 the DCF77 time signal, or even just morse code?

What are some alternatives?
