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!
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
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.
And I relearned something I only thought I had a grasp of. Now to understand the snubber resistors on the tank circuit of a large inverter I'm working on. (825VDC to 208 3Phase)
Thanks for the video. I'd like to know how IC circuits like the ESP32 can incorporate RF resonance components ? Are the capacitors and inductions etched on the Silicon ? Best Regards.
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?
hey man. great explanation. the fact I understand it means I'm learning. they have an r&s spectrum analyzer at the local makerspace covered in dust haha
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!
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!
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
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.
Hi , Simon here. I bought a 75w 905nm pulse laser diode thinking it was a non pulse diode. I can’t afford a pulse driver 100ns 1% duty 12.8v 30A so I am trying to make one cheap. I can get the 100ns PWM using a 555 timer but I am not sure how to get the power into the pulses. Should I use an inductor 20nH with a capacitor ? And if so how do a make a crowbar switch that resets in 100ns ? What is the simplest way to drive the diode. Can I simply use a mosfet avalanche rated at 30A with a current regulator like a buck converter ?
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.
f could be log-scaled :)
This was one of, if not the best explanations of LC circuits I've ever seen demonstrated. Well done! I am a region 5 General Class Amateur.
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!
A fantastic presentation on what many consider a tankless subject.
LOL - took you a minute to come up with that - made me smile.

Bruce Deville, KE5CPL.
Awesome explanation of the components and the formulae, and the SDR really helped.
Nice presentation, TNX! Bookmarked to use as an adjunct in our General/Extra classes. 73 - Dino KLØS

Wow!! That took me straight back to a seven week comms module I did in the UK Armed Forces back in 1989!!! Thank you for that!!
Excellent presentation of the concepts! Loved it.
Thkyou brings back memories from early days
Right
Both very interesting and informative video! Great job! 😀
Thank you for helping understand the concept of inductance with us all. Good day too. VF
The best explanation I ever seen... thank you for your time and share.
Yes He Did let us all SEE it Thank You
Excellent tutorial. I look forward to your videos.
Great job! Your very to the point without going too fast.
Thanks so much for this! It is the best explanation I've seen on this subject.
Best video on RF basics!
This is the perfect follow on from applied science impedance videos. Subscribed
Excellent job, young man.

nice me XW4860's X3 15 years old now He Did So Good Explain & Show
you are genius in presentation, i understand you very well
Can you Demonstrate how to fine tune a RF Amplifier in a tank circuit? Like variable capacitors in parallel with inductors.
Fantastic explanation of a complex subject. Great work!
Lovely intro into LC circuits : thank you
Excellently explained.
Spot on video.Will be watching what else is on your channel.
Thanks for the video. I'd like to know how IC circuits like the ESP32 can incorporate RF resonance components ? Are the capacitors and inductions etched on the Silicon ? Best Regards.
I think they use crystal oscillators
Great video. Clear and to the point. Thanks.
i recognize you from your earlier channel whose name i'm now forgetting. cool to see you stepping up your game!
Beautiful explaination....!!!
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?
Great video! Very interesting mag loop design with that remote variable cap, any video or docs on how this was made?
hey man. great explanation. the fact I understand it means I'm learning. they have an r&s spectrum analyzer at the local makerspace covered in dust haha
superb video!
thank you sir
I was really looking forward to hearing about how tank circuits work
Bro this shit fire can't wait to see more from you and the series
Incredible teaching!!!
Excellent video!
0:51 - Ahoy,matey! Props for using a tube. I've heard tales of someone sailing a 1W VHF amplifier using a 6AK5 tube.
This is why I stick to audio, the higher the frequency the higher the headaches!

Thank you. A very well done video.
That's one heck of an antenna! It looks like it should handle about a million watts!
Tanks for the video.
nice use of SDR at the front of the video
I finally get it, great video!!!
How did you get to element14? I miss your channel
Please join the community. Lots of good electronics info and tons of very knowledgeable people!
see links in the description above
this is so good
Well explained. Thanks!
Please in future videos allow the ability of downloads via you tube extensions.
Use youtube-dl.
Could you find out the pros and cons when comparing wound coils of many setups VS stacked(wounded technically) Starship Coil setups?
That looks like the cubs logo on your t-shirt.
Brilliant
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
Now the next step is how these resonant circuits are used in graphic equalizers. :D
Pretty cool. Love the tee bud lol.
Great explanation. Thank you. I now understand S21 but what are S11, S12, and S22?
So nice sir
Excellent
When its in parallel, isn`t that blocking the resonant frequency from been passed?
Very good I love you!
Great video 🌺🌹🌻🌼 go on 🍎
Do a video about fm transmitter and receiver

What's that other signal?
Nice
Q: What is a tank Circuit in a glass gas filled envelope?
A: A gas tank.
is this magnetron?
variable capacitor from the 50's
Wow that video went fast, I even paused it to screen shot the formulas, last week I couldn't remember x sub l, how embarrassing
Birlliant!
I learned electronics from books.hes legit

ah right, the current source, i see the sticker in the background.
I thought this video was about a battle tank's electrical system.
Oops.
The second I saw the math equations, I lost interest
NOT a waterfall!
How is it not? I'm genuinely curious.
@@matthewkriebel7342 As I can't post an image(!), look it up.
@The Current Source So what do you call an actual waterfall plot then??
