gr-adsb

2 140 2.7 Python

GNU Radio OOT module for demodulating and decoding ADS-B packets
gr-nrsc5

5 118 8.4 Python

A GNU Radio implementation of HD Radio (NRSC-5)

Project mention: Listen to HD radio with a $30 RTL SDR dongle | news.ycombinator.com | 2023-11-05

The code of nrsc5 (and my transmitter project, https://github.com/argilo/gr-nrsc5) would be the best source of information for the undocumented parts. I do have some private notes, but the useful information has already gone into the code.

ais-simulator

1 30 5.2 Python

Create and transmit AIS frames via gnuradio toolchain and web application in browser. Provides a websocket to PDU message block to change frame content on runtime. Works in burst mode, a frame is send on change immediately, one time. Transmitter remains silent until next change event.
gr_DCF77_Receiver

1 18 6.9 Python

DCF77 time signal GNURadio receiver for SDRs incl. live decoder and transmitter simulation. It covers both OOK and phase modulation.

Project mention: Casio G-Shock time sync radio | news.ycombinator.com | 2023-08-16

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?

gr-X10

1 0 3.8 Python

Project mention: Help and resources on OOK decoding | /r/GNURadio | 2023-05-24

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
