Hey there! Boy, it's been a long time since I touched that code. It's very "hacked together", and needs some love!
I'd recommend trying psk31_rx.grc with this video[1]. If you have youtube-dl, you can save it to a wav file. For the TX side, I didn't really get that flushed out properly. The audio sink doesn't like it when you stop sending samples to it, and I couldn't figure out a tidy way to clean things up. In the mean time, look at the vector source in psk31_tx.grc. \x80 is the "preamble" byte, and everything else is just plain ASCII. That should get you up and running! Maybe if I have some time later, I can get a transmitter block up and running with the osmocom sink. It's just a simple AM transmitter. - Tim [1] https://www.youtube.com/watch?v=qHNvp7FfP6E On Sun, Jul 10, 2016 at 1:12 AM, Eoin 0w3n <eoin.0...@gmail.com> wrote: > Hi, > I've been having some fun with gr-psk32 ( > https://github.com/tkuester/gr-psk31). > > The aim is to be able to send ascii with a hackrf nd then receive with > an rtlsdr. > > For now, I would just like to get the rx and tx examples working over > audio/soundcard. > > I just added an audio source block to the "psk_rx.grc" and left the > "psk_tx.grc" example as-is. > > When trying to tune on the right hand wide waterfall, I seem to get > something close around 1850.
