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.
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
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.
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?
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)
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
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
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 :)
You’re correct. Oversight on my end!

Excellent presentation of the concepts! Loved it.
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.

Nice presentation, TNX! Bookmarked to use as an adjunct in our General/Extra classes. 73 - Dino KLØS
Hopefully it helps. 73!
A fantastic presentation on what many consider a tankless subject.
LOL - took you a minute to come up with that - made me smile.

Thkyou brings back memories from early days
Right
Both very interesting and informative video! Great job! 😀
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!!
Thanks so much for this! It is the best explanation I've seen on this subject.
Thank you for helping understand the concept of inductance with us all. Good day too. VF
Great video. Clear and to the point. Thanks.
Spot on video.Will be watching what else is on your channel.
Best video on RF basics!
Can you Demonstrate how to fine tune a RF Amplifier in a tank circuit? Like variable capacitors in parallel with inductors.
Incredible teaching!!!
Excellent video!
Excellent job, young man.
Great job! Your very to the point without going too fast.
Excellent tutorial. I look forward to your videos.
Thanks. I look forward to making them!
Excellently explained.
The best explanation I ever seen... thank you for your time and share.
Thanks!
Yes He Did let us all SEE it Thank You
Awesome explanation of the components and the formulae, and the SDR really helped.
Thank you!
This is the perfect follow on from applied science impedance videos. Subscribed
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.
This would be a fun topic. Usually they’re etched on a pcb.
I think they use crystal oscillators
you are genius in presentation, i understand you very well
Great video! Very interesting mag loop design with that remote variable cap, any video or docs on how this was made?
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?
Lovely intro into LC circuits : thank you
Well explained. Thanks!

superb video!
thank you sir
Thank you. A very well done video.
excellent teacher
I was really looking forward to hearing about how tank circuits work

Tanks for the video.
Bro this shit fire can't wait to see more from you and the series
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
Could you find out the pros and cons when comparing wound coils of many setups VS stacked(wounded technically) Starship Coil setups?
Fantastic explanation of a complex subject. Great work!
I finally get it, great video!!!
How did you get to element14? I miss your channel
Thanks. The folks at element14 invited me to the party. I still have my channel, just been a bit busy these days.
Please join the community. Lots of good electronics info and tons of very knowledgeable people!
see links in the description above
i recognize you from your earlier channel whose name i'm now forgetting. cool to see you stepping up your game!
That looks like the cubs logo on your t-shirt.
Pretty cool. Love the tee bud lol.
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
nice use of SDR at the front of the video
This is why I stick to audio, the higher the frequency the higher the headaches!
That's one heck of an antenna! It looks like it should handle about a million watts!
Please in future videos allow the ability of downloads via you tube extensions.
Use youtube-dl.
Now the next step is how these resonant circuits are used in graphic equalizers. :D
0:51 - Ahoy,matey! Props for using a tube. I've heard tales of someone sailing a 1W VHF amplifier using a 6AK5 tube.
Ahoy! It was VERY crude (and dangerous) but worked.
Brilliant
When its in parallel, isn`t that blocking the resonant frequency from been passed?
Great explanation. Thank you. I now understand S21 but what are S11, S12, and S22?
That might be a bit deep for this segment, but I can point you to a good R&S presentation ruclips.net/video/-Pi0UbErHTY/видео.html
this is so good
Thanks!
So nice sir
Excellent
Do a video about fm transmitter and receiver
Very good I love you!
Q: What is a tank Circuit in a glass gas filled envelope?
A: A gas tank.
Great video 🌺🌹🌻🌼 go on 🍎

[EDIT] Oh, it's just another name for LC circuit. Cool, learned something new today.
What's that other signal?
I’m not, sure.. I tried to move away from it for a clear demonstration, but there were signals all over the place. 🤔
Nice
is this magnetron?
Birlliant!
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
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.
That's next week ;)

NOT a waterfall!
How is it not? I'm genuinely curious.
@@matthewkriebel7342 As I can't post an image(!), look it up.
It may be a bit of a misnomer, but is generally the accepted term for this plot in ham radio and the SDR world.
@@AmRadPodcast So what do you call an actual waterfall plot then??
@@qwaqwa1960 A waterfall plot.
