I've wanted to play with gnuradio but never got far. But your video helped jump start me. I don't have a hackrf :(. So I put in a 3khz low pass filter on the audio and set the carrier to 6khz, Put in a File WAV sink and saved to a wav file. In a seperate project I used the File WAV source and a AM demodulator to demodulated it. Audio voice transmitted on a 6khz carrier. Demodulated it sounds just like normal voice.
Great demo except for the final part where we route the audio to the transmitter - Does that mean the AM modulation occurs inside the transmitter automatically ?🤔 I.e. The carrier and modulated signal get generated by the HackRF transmitter!
Cheers. Sometimes I can't be bothered putting a video like that together for the effort I need to do and how little they get viewed compared to simple ones. Maybe one day.
@@TallPaulTech completely understand. Working on RF EE degree. Recently go a job doing this stuff. It is my jam. Lots og GNU radio videos. Hard to find good ones, like your video. I should start a Playlist of the good videos I find. If I had my way, it would be a list starting with CW, AM,... Then the rest of the modulation formats in chronological order.
i did till transmitting and got the below gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.10.9.2 built-in sink types: uhd hackrf bladerf soapy redpitaya file [INFO] [UHD] Win32; Microsoft Visual C++ version 14.2; Boost_108200; UHD_4.6.0.0-release [1m[33m[WARNING] SoapyVOLKConverters: no VOLK config file found. Run volk_profile for best performance.[0m [INFO] Using format CF32. no error is occuring but the graphs arent coming either. without osmocom everything is working fine, anything to fix it?

What a fantastic video. Super cleverly done. Many thanks for that!!!
Thank you. It took a bit of time to make, but people generally only like the shitty stupid videos I do.
Nicely done. Very patient pacing and easy to follow. Please do more.
Wow, explained in such a great way. Great work mate. Really enjoyed it!
Paul, this gnuradio courses are brilliant. Thank you! 🙂 👍
Very nice, for a radio noob coming from another engineering Field I could follow along what is happening! Thank you!
You're a perfect teacher!
I've found it very valuable.
Great video keep going , thank you

I liked the video and how you explained AM, really insightful ! do you have in plan to do something similar for FSK\PSK ?
I go through phases of what I'm up to. I won't rule it out, but not any time soon.
@@TallPaulTech thanks 🙌
nice video great channel
Well explained!
I enjoyed the video. Do you have any others such as DSBSC? Then maybe SSB?

Yeah, and if I could be bothered, that's how I'd have probably done it too. It was on my mind, but.... didn't do it.
Hello thanks you for this great video. Can u pleas explain how can i demodulation this signal with gnu radio instead gqrx.
that was fucking good. thoroughly enjoyable.
Yeah, that's what your mamma said too
😄😄😄😄
Approved! Next bang a linear on that hackrf and let there be RF!
Awesome!
Thanks for the great video - now do SSB :-)

Cool.
I can’t do that tutorial because it happens error 3221225501 with freq sink or waterfall sink
