In this episode, we explore the basics of series and parallel resonant circuits, also known as tank circuits. We look at how frequency affects the reactance of capacitors and inductors, as well as what happens to their reactance at resonance. Using an SDR we visualize what changing the capacitance looks like on a waterfall plot, and we look at both series vs parallel LC circuits on a spectrum analyzer: bit.ly/3lIFNQa

This is an excellent tutorial indeed. Note that @5:25 the relation *X_L(f) = 2πfL* is a straight line with respect to f, not a curve.

@leandroebner1405 2 года назад

f could be log-scaled :)

You’re correct. Oversight on my end!

Dc to Daylight was & still is my favorite article in E.A ( Electronics Australia) magazine of which finished 15yrs ago now, Silicon Chip magazine Australia is still fairly good but, the intuitive explanation in this video are next to none. Thank you, have a good one. Ciao..!

@AmRadPodcast 2 года назад

Very cool. Looks like there are some archived EA articles online. My favorite magazine was Radio Electronics (later Electronics Now) here in the U.S. I wish I would have kept them all.

@brandtharen 2 года назад

Great video. I watch old radio repair videos and now I have a better understand of what those big multi plate variable capacitors are doing in those radios.

Thank you so much for presenting this! It is amazing to see a real world example of what I have only been able to read about in textbooks. Keep up the great content!

@brucedeville9053 2 года назад

I love the video. Back in the 1950s when I first got into ham radio (as K5GTB) it was easy to visualize these circuits because you could actually see the components. Not so much so today. Bruce Deville, KE5CPL.

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

@fmphotooffice5513 2 года назад

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.

@ik04 2 года назад

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!

@sincerelyyours7538 2 года назад

I'm in the process of designing my first mag loop antenna. I'd be interested in learning more about your loop design. Do you have a video or write-up of how you made it that you can share, by chance? It sounds really interesting!

Hi Derek. I have a question. If we have two simple AM radios sharing the same antenna, can the two radios be tuned to two different radio stations at the same time?

Guy wants to explain to me how tank circuits work. I click the video to find out what tank circuits _are._ 😂 [EDIT] Oh, it's just another name for LC circuit. Cool, learned something new today.

@davidprock904 2 года назад

With different electrolysis setups to split water into HHO, I would like to learn how to determine the best frequency to send into the setup, and if the demand changes how to follow it live so the frequency can adjust in real time
