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

Listen to HD radio with a $30 RTL SDR dongle
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.
- How can I do this? Is there a tutorial video?
- HackRF WFM Transmission with Station Data etc
- mayhem equivilent for pc
- HD/DAB pirate radio?
What are some alternatives?
