Wow, I've been into amateur radio and building things from scratch for a few years now since I got my license and this is an awesome explanation and analogy how resonant frequencies work! I have a better understanding and even learned some new things! Only one "minor" technical clarification at 1:49 though- Amateurs can NOT "broadcast" or else you'll be hunted down and fined heavily! We "transmit", which is just peer to peer normal conversations, vs broadcasting which is one sided news aimed at a large audience or music, in other words an almost nonstop transmission or copyrighted things. Only BIG radio stations are allowed to do that! 😜

Great explanation!

Unfortunately, I didn't know the prerequisites. I didn't understand everything.
