This video is quite personal to me, because of my family history. My father, Abraham L. Rader, was born in 1906, of immigrant parents, and when he was a teenager, he was interested in radio. In those days, radio for ordinary people was a crystal set, with all the problems of amplification and tuning that this video makes clear. But my teenager father started a company to make and sell crystal radios. He also hired an engineer to try to solve some of those deficiencies. My father had no formal training in electronics, just hands-on experience. His engineer was a perfect fit, very bright but not entrepreneurial. That engineer invented the superheterodyne radio. I wish I knew his name. My dad's company sold the first superheterodyne radios to ever reach the consumer market. Sadly, from our family point of view, Sarnoff and RCA had the necessary patents and my father, who didn't even know what a patent was, found that he had to leave his business or be sued. He never talked to me about that part of his life, but of course my mother knew about it. When he died, I put together an obituary speech and that was when I learned about it.
That's an incredible story. Unfortunately I've heard a lot about RCA bullying the competition. I believe they almost killed FM radio before it ever happened too
Is it Armstrong ... guy that invented superheterodine - officialy (!!!) ... + he later on invented FM ...and had tragic clash with Sarnof. ...etc etc ??? 😮
I assembled my first receiver when I was six years old. Superheterodyne made at 10 years old. Today, after several decades, I found out why the receiver worked. This is all very interesting.
Radio seemed to me some easy thing to understand. But the more I listened to,the more I got the idea that Radio is still has a very wide process of evolution. I wish all the best in your research,Vlad!
Any video on Radio Control circuit's , explaining the schematic how the signals are transmitted from transmitter and receiver to control the motors on RC toys
Fully agree. I want to listen to the fascinating information, not music. Couldn't get to the end of the video because of the music distracting my concentration.

FYI, You left out time dependence of sinusoids in first cosine products.
This is a brilliant video. Thank you!

😲 wow 🤩 impressive to say the least 👍
I though I was watching how radios work not how rocket science works 😂
the background music is so annoying. such a shame. your demo is very good, but i can hardly follow you with the noise in the back

Vlad: do not despair, besides the useless critiques. Keep going, my friend. Excellent video.
How you created that? It's matlab?
Gnuradio (Python)

Can I get the application's set up or where to download it?

I thought this was a flute and Doom channel. What's all this radio hubalamub all about?
