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. I end up receiving "holmoewnrmg\n" which looks to be something related to the transmitted "hello world!\n" vector in the example. Has anyone got the tx and rx working for gr-psk32? Im sure its just a small setting somewhere. Thank you :-)
