Without exaggeration, this is probably the best video on Radio Theory I’ve seen. And I I’ve recently seen a lot. In just the past year or so , I’ve taken up Amateur Radio as a hobby. Actually, I’ve managed to steer clear of YT for along time until I realized what a great learning resource it can be, once you get past all self important, narcissists that want to stand in front of a camera. To be honest, I’ve happened upon your videos several times in the past. I never watched because it’s been my experience that videos with the presenter in front of the camera spend more time on image than content. There were only two or three YT channels with presenter in frame that I watch on this topic. Now, I have one more. Thanks for the Video- Jason Burchell. I do have a thousand questions on radio theory and electronics but I’ll ask those a bit later. Sorry, the comment is so lengthy. So much for brevity

Excellent presentation. Reminds me of the beginning of my learning of passive components back in caveman days. That's when you realize there aren't very many passive components to grasp, but an infinite path to learning how to implement them. The advancement and achievement in the field of electronics through the years lets you experience the evolution almost in science fiction terms. Things that ere impossible or just theoretical in the 1980s are commonplace today. Nice work. Regards.

Hey! That looks very similar to my Magnetic loop! Mine is around two meters in diameter and tunes 10m to 80m. The biggest difference is my capacitor is a trombone style I made with eight coaxial copper pipes. In order to avoid interference with all the metal in a tuning system, mine is hydraulic, using water in a cylinder connected to the capacitor. Cool video!
