Outright amazing video. I got a HackRF a few days ago. The first day I had it I built a PSK31 transmitter. I left it hoping to come back to it later, and I am. Unfortunately it seems like gnuradio's PSK Modulator block is deprecated, but more importantly, no longer working, and same for using a Constellation modulator in BPSK mode, my data just isn't going out right, but it worked a few days ago so I'm sure I'll figure it out. Nonetheless, You are amazing for explaining every thing in detail. One of the big things to me was how you calculated the exact value of Interpolation the rational resampler needs based on the minimum samplerate of the USRP while also considering symbol rate and the desired baud rate (31.25). I wrote down what you said and documented it, I'm sure it'll come in handy many times in the future. Thank you for explaining everything so well! :)
Hi Louis, I'm new to digital signal processing and inexperienced in writing Python and C++ scripts. I was wondering if you would upload that psk31 script to GitHub or something so others can use it for their learning purposes. Thanks.
I can’t remember, and I lost the flow graph. The PSK Mod block pulls in a byte at a time, and for BPSK it may just use the LSB, thus bytes/sec is correct.

Louis - Excellent piece of work. Well presented. Just what I have been looking for to help me get up to speed with GRC.
Its great video and great explaination.. Please make more such videos...
Very well explained. THANK YOU!

This is great work thanks!
Nice Video. Thank you. However, You write in the left block is 31.25 bytes/sec. Do you mean 31.25 bit/sec?

@@rfengr00 Thank you for your kindly reply
Hi, I'm interested in doing the PSK31 receiver with GNU radio, do you have any tutorial for this?
Daniela Guerrero sorry I don't. I actually lost the code I did in this video.
Great video, thank you for sharing !

why not provide a working GRC file ? lame.
