Best video on this topic by far!! Thank you very much!

Hi Prof Jason, I have been an embedded systems developer for around 35 years with a fair background in traditional analog RF. I have been dabbling with SDR and GRC for the last 8 months or so and I need to tell you that this series has been a godsend. I came across it about a week ago and I have so far been through most of it. For me it has provided a lot of theory and detail that has been difficult to find anywhere else, you have filled a lot of gaps that would otherwise probably have taken me years to do in the absence of it. What has been particularly enlightening so far are lessons 11 though 19. I am yet to get through the rest, but if what I have been though thus far is anything to go by I am sure it will be just as enlightening. Thank you so much for posting the series.

Thank you. This meant a lot.

Hi Prof Jason, I can only say that your students are very lucky to have you. I hope that you would consider covering the popular but confusing channel coding techniques in a future series. One question perhaps as an add-on for this series: For denser constellations (beyond QPSK) how is timing lock achieved? I'm thinking one can not 'simply' rotate based on the sign of the received IQ data since there are many more points per quadrant.

It's been at least ten years since I saw GNU Radio and I don't remember anything anymore. Your video was very important to remember everything. Thank you very much!

Thanks for the tutorial - I have programmed my SDR's in C# and Python, but this tutorial really shortened the learning curve on getting going with GNU Radio. I used this tutorial with my ADALM Pluto with very few changes - running the latest version (Feb 2024) RadioConda on Windows 10. Works great! You have nothing to be sorry for - your 'Live Coding Demo' went better than 99% of the live coding demos that I have done! As we say in R&D: "What could go wrong?" Ha, ha, ha, ha...... ;-)

i aslo have adal pluto please shares blocks of fm receiver

this is pure gold. thank you, I can't wait to dive back in to RF and signals and aaaaaaaaaaaaaaaaah

Amazing video. I would highly recommend the DSP teachers to follow this! Prof are you making any tutorials of OFDM signal transmission and reception. It would be very interesting.

Thank you Prof Jason 🙂

I follow few tutorial and ended noisy audio FM, but from you I got cristal clear audio. thanks bro

Great video. Question: would it be beneficial to use a bandpass filter instead of a low pass one?

thank you its great

Hi Prof Jason, thank you so much for the lesson. I am not sure why I am able to hear other radio channels, beyond the low pass cutoff frequency (200KHz), is it normal?

I'm not sure if its an issue but at the end when I try to tune between radio stations while listening it doesn't seem to pick up every radio station only a couple. Getting a bunch of write fails in the logs. edit: Seemed my RTL-SDR didn't like my usb3.0 port, switched to a usb2.0 port and it started working fine

Hi. Goog. Thank you.

omg the only instructions i can find that works.thank you...when i turn the radio on.i get static..anyway to fix that?

problem solved.forgot to adjust my antenna

what is the ubuntu version? and Gnuradio version?

Hi, you know what error code 11 means?.

I dont get something , you say " We are going to throwing out samples that are not in the central region " but from my understanding the decimation happens after the filtration so you are throwing mainly samples of the central region. And therefore the aim of the decimation is just to reduce the sample rate to reduce computation time at the cost of quality . Or did i miss something ?
