Is there a path from absolute beginner or is a basic level of understanding taken for granted?
Tesla's nano power grid!
If anyone is on the fence on becoming a patron. I Have been a member for almost 2 years at the highest level now and it's worth every cent!
What are the Wavelengths of your external antenna?
@@whaleneck1303 Thinking the same thing. Tesla's free energy tower. There is a smaller version of a [X] shape UN-powered wire loop antenna using a variable capacitor that will tune ANY AM radio to perfection. Search for it on CZcams for a demo and the specs to build it. As a former B-747-400 International pilot (retired) back before (CPDLC) Controller Pilot Datalink Communications, which Russian ATC enjoyed using all the time now, HF radio was the only way to go, antenna tuning was pretty simple on new aircraft....
This guy is an absolute genius. This is the most detailed, accurate, intelligent and informative electronics channel you will see on CZcams and in real life. I have watched all of the electronics channels on CZcams and this one is bar none the best channel for professionals, hobbyists, and even the beginners. Not only intelligent but also does everything professional and meticulous
YES This is a very educational experience!!
I think this video explains perfectly why I love having electronics as my hobby. There's so much I don't know, so much to learn. I occupies my mind. I run my own small engineering company as a day job but learning electronics from people like Mr Carlson is becoming a bit of a 'passion'. Every small breakthrough is a massive high for me.
I have a heap of vintage valve radios I've been wanting to restore and this channel has taught me so much about the proper technique to use.
Manuel at Electronics Old and New by M Caldeira is also an excellent teacher when it comes to repairing
vintage tube radios. Step by step process of repairing of your typical European manufacturer of vintage
radios is well demonstrated if your serious on getting to your restoration of your collection!
Excellent discussion of coil coupling. And 'no trickery!'
Well, I was at work today and eating my lunch watching this video… this had gotten me very interested after I heard it was about the new antenna you had built!!! Then it was all ears and eyes on the deck, very excited and happy to here more about this antenna! Thank you Mr. Carlson
1Hz sounded like the "alien signal" in Contact :) That was a great demonstration!
Very impressive that the antenna picks up enough signal to light those LED's.
Can’t wait to see more with the 3-6-9 antenna. Maybe baluns and antenna tuners.
Thanks for sharing Mr Carlson. I started my electronics career at the age of 7, designed, built & sold radio bugs to schoolmates, did my BSc Electronics Engineering degree, worked at my dream job at Marconi and now run an IoT business.
Thanks for sharing your story as well Jas!
1 cycle out sounded like the "alien signal" from the movie contact.
How many angstroms was that?
Paul, you do have one hell of a setup there. Great video as always. I appreciate the time you put in your quality videos, a pleasure to watch. Best regards from germany, my friend.
Im really digging this format. Thanks.
Equipment I could only dream about. And if I could just use 10% of their features I would be satisfied enough.
So awesome that Mr. C uses classic vintage and custom built equipment.
Mr C's Lab spins me back down the years and the days of my youth watching Star Trek. Someday Paul might show us his Top Secret VTWD (Vacuum Tube Warp Drive). Maybe even a teardown. Ya knooow... That's how he travels back in time to find all these vintage gems. Except for the ones he invents, like the Internet, but that secret is safe with me... Cheers!
The theory behind WARP drive engines is to compress the 'space' in front of the spacecraft
and 'expand' it at the back of the spacecraft. -- Though no one has been able to figure out
how to do it. Thus like evolution of the species, it remains an unproven 'theory'.
It is unlikely that civilization will survive long enough to discover the answer.
All we have discovered is 101 ways to destroy this world we live on - Newer methods of
ecological destruction are being invented.
Great Video, I'm 78 yrs old, and still thirst to learn things. and every now and then something like this comes up and rekindles my memory banks of how things work. the beauty of the human mind is you can't fill it up. it will continue to absorb till the end. Thanks for the "Fill Up" of today!. and for sharing.ECF
Glad you enjoyed it!
pretty soon all the radio stations in a 100 mile radius are going to wonder why their breakers keep tripping when you short those antenna leads ;P
Sorry this video had to end! This was great!
Glad you enjoyed it!
I wish that you had a SDR on that 3-6-9 antenna that we could listen to your SDR online that would be cool.
Paul, I am so envious of you! Well done, you earned the bragging rights!
Very cool! I didn't realize it could also work this well in the AM Broadcast range.
SWR at 1MHz is in the One's. I will show this on the VNA soon.
Well, there you go, it a great example of inductive coupling.
Back around 1958-'59, Popular Electonics (or maybe Electronics Illustrated) had a do-it-yourself project for an entirely antenna-powered receiver/amplifier. Tuned to a strong local station, it generated enough voltage to power a transistor amplifier. Then a second tuned circuit could select a different station and be heard louder thru the amplifier.
I have one of those HP function generators. Neat piece of kit.
I must admit that I cannot watch this video unless I have a great dinner ready and a few good beers... Semper fi!
My first experience with an antenna was at age nine with a crystal radio. I hooked a wire to the radio. The wire was hooked to a broken steel slinky, which was attached to a basketball hoop. I heard a local AM radio station advertising McDonalds hamburgers.
you always a fun time for me Mr C! Never to old to learn something new
I just love your videos. Particularly your great attention to detail.
Thank you very much!
Very interesting! Looking forward to learning more about your 3-6-9 aerial.
Hi Paul. That is a cool test gear. I have the same hp generator that you are using and the old gilrl just keeps clicking along. You have one of the best setups for videos also. Never a bad one.
I have learned a lot from your videos even after doing repairs on ham radios and amps for many ryears. Thank you.
The 9:27 mark:
Nicola Tesla at work...induction
ALL HAIL NICOLA TESLA!!!
Damn, Beat me to it.
I'm retired but I've done nearly everything in electronics during my career except....radio !
I enjoyed the magic show !
The LED set up reminds me of the first radio I built, a crystal set, a radio without power. Thinking about it, this could be used to light up low drain signs, like a house number for example. I feel some experimentation coming on!!!! As always an interesting, thought provoking video
Nice, efficient enough to light up leds just from RF in the air like a wireless power setup. I guess a downside to that it's also very efficient at picking up 50kV spikes from lightning strikes even at 10-20 miles away. I don't think the leds would like that. Doesn't receviers have peak input signal limits of just a few V before something bad happens?
Input capacitors, and clamping diodes, can protect the receivers front end.
I remember that Art Bell was experimenting with a loop antenna he built at his place in Nevada. It was very large and he got a massive amount of voltage off of it. It is reported to be 1595 feet in diameter and has a double loop of wire.
Induction... it's amazing stuff. How many LEDs could be lit up this way? The antenna receives RF from remote radiostations, obviously, which is what powers the LEDs. I am curious - would the antenna be 'good enough' to power LEDs from just cosmic background radiation (assuming no radio stations) and/or anything else it'll pick up?
I am asking because it reminds me a bit of Tesla's experiments with a elevated plate being charged up and periodically discharged into a capacitor, gathering supposedly minute quantities of energy. I think later in his life, on July 10, 1932 Nikola Tesla stated: "I have harnessed the cosmic rays and caused them to operate a motive device." That may be a different experiment, but interesting too.
All this is very interesting stuff. Thanks for sharing, mr. Carlson! Much appreciated!
I guess it depends how far away a thunderstorm is.... ? In fair weather it can be 100-300Volt per meter (height), and near a thunderstorm it will be in the thousands of V/m, strongly peaking when striking. I don't think it is all rf, but I could be wrong.
@@erikdenhouter That's an interesting observation - that's static electricity, I believe, but I am not sure if that's the same phenomenon mr. Carlson showed us, which is likely RF energy. I'd love to hear from him about the phenomena we watched. It's fascinating.
@@alpcns You're right, the capacitor shows it is about rf only.
@@erikdenhouter I wonder how close his 369 is to overhead power lines ... could he be getting loose coupling to them ?
Or even electromagnetic radiation at ELF ... 🤔
@@peterfitzpatrick7032 I don't think so, Paul doesn't speak about power lines anywhere. And (as I read) ELF (extreme low frequencies, in the tens of Hz) can not easily pass a .1 µF capacitor, but... the current that makes these LED's glow is low, I think not more than 75µA.
You have demonstrated that the antenna extracts a nice chunk of energy from the radio waves it encounters. The method of multibanding is very clever, too. But the "goodness" of an HF antenna is not determined by raw signal strength, because due to the relatively greater amplitude of atmospheric noise compared with the internal noise generated by the receiver, it's possible to simply amplify the output of an inefficient antenna as much as is needed. This is why small loops with preamplifiers can be good receiving antennas.
The real test of a receiving antenna is its ability to provide a high signal-to-noise ratio. Given that we are not talking about highly directional antennas, that comes down to rejection of local manmade noise. I believe that since the outer shield of your coax is not decoupled in any way from the common lead of the antenna, it will provide a path for local noise from your noisy lab back up into the antenna. A worthwhile experiment would be to connect a ferrite choke "balun" (not really a balun, but that's what most hams call them) at the feedpoint and see if noise pickup diminishes.
Nice WWVC Rx. Nice Variable RF coupling transformer demo!
Nice box... At some point it would be fun to add a 10MHz reference to my lab, but given our business focus on analog audio, its not really a high priority to have ultra precise frequency measurement.
I did a similar experiment on my 160 meter Inverted-L antenna. I live in the middle of three 5KW AM broadcast stations. Each are about 2.5 miles from me. Connecting a full wave diode bridge across the antenna terminals I read 36 volts. Shorted I get 8 ma. Lights an LED very bright! Connecting a frequency selective level meter I measure +10 DBm on two of the three and a little less on the third.
Thanks for the demonstrations. The powering of the seven LED's from the antenna was the most interesting. The estimated minimum power is 14 mW based on 1 mA for the brightness and 2 V for green LED's.
Thanks Paul. that's an awesome experiment for the antenna efficiency. the ground magic is under considered in electricity/electronics schools, at least in my humble experience.
I cannot wait for ur new antenna vids!
Thank yóu for sharing
My pleasure!
Actually 3 thumbs up. You are doing some of the things i did when i was 15. Memory lane 😁 with some new stuff!
Hey... Made me think of the STS-75 Tether incident.. CHEERS! 🔥❤🔥
Phenomenal. Thank you.
A wealth of knowledge. Looking forward to the next vid👍
Thanks 👍
Mr Carlson, have you considered ground rod earth loops by having four rods as you described. Also, regarding the distance of the rods apart giving rise to bigger earth loops but better overall impedance to earth. Also, the resistivity of frozen soil compared to warmer soil for example....?
I guess it's worth having these new issues in comparison to a noisy grid tied earthing system but would love to hear your input or perhaps experiments.
Very interesting. Cant wait till you show us more.
Very interested in the effects of the inductively coupled antenna segments, and hoping you do some experiments specifically on them.
Paul, It might be interesting to see the potential difference between the antenna-ground and the bonded house-ground!
I'd guess it could be at least several volts potential! Just curious...
Interesting,... listening to the antenna tech.
Wow that's really neat, now I need to try some LEDs on my HF antenna :)
I think a video on frequency standards (and some low end/hobby level alternatives) would be awesome
5:50 Delicious!! A nice box of candies,......
Hi Paul,
That's a very effective antenna. When you were measuring the voltage across the antenna leads, would a VTVM give a more accurate reading? You and the family stay safe. 73 WJ3U
Yes, the HP-410B would be a better choice for reading the RF level. Thanks for your kind comment Don!
And removing the LEDs while taking the reading would be better too. Very impressive. I wonder if most of that power is coming from just one local station? It would be interesting to take some readings via bandpass or tuned filters.
My favorite drink is beer but it’s only water when attending a Mr. Carlson Lab.
amazing!
Explaining what the test setup is first would have been very helpful to understanding the adjustments you were making in the first 3 minutes. "I have a generator, a WWV receiver," etc... Excellent material, as always. Congratulations on the success of the antenna.
Nice video, thank you :)
Fascinating demonstration, and very well explained!
Very interesting demo! Though they are low current, high brightness LEDs, the fact that you can light up a row of them like that with no power input whatsoever is fascinating. Very Tesla-esque as many other people have mentioned. Paul, I'm interested in how you calculated the three antenna lengths and how the shorter ones inductively couple to their longer extensions. Is there a coil between the two lengths or is it just an insulator?
Like this a lot
I wish I could fully understand I have had a couple of serious head trauma. So I am having some trouble understanding the principles involved. But I greatly enjoy watching your work.

Great video Paul..Learning all the time..Fascinating how induction works..Thanks for sharing..Ed.uk..😀
You are amazing. I started to love inductors by the way. I design wireless leds.
In order to make this video more self-contained, and for the benefit the uneducated, it would be useful if relatively unfamiliar terms such as 3-6-9 antenna could be redefined.
Hi Paul, excellent video as always thank you. I will now go and tweak my substandard antenna 🙄🙂
Glad you enjoyed Dave!
This new antenna would be great for demonstrations with a simple crystal set. You could demo variable inductive coupling methods, achieving selectivity, etc., etc. I've always found crystal sets to be loads of fun and very instructive.
Cat whisker receiver, 👍
Super !
Always amazed at how good your videos sound.
Thank you very much!
Great antenna. Simple theory but it looks like it took a lot of know-how to actually implement. Would love to have a video one day that details your background and how you acquired so much knowledge of fabrication.
The magic of RF.
Nice demo!! I've known this could be done for some time.
That demonstration was really cool and informational. Thank you, Paul. Is directionality a factor in the 3-6-9 antenna?
Did you build in any meaures against static electricity from your antenna? I can imagine it can generate high voltage spikes when there's a thunderstorm nearby that can deamage your equipment. I'd really like some more info about how this antenna works. It seems to function really well!
Yes, oddly enough, we rarely have lightning here, but when I was at the top of the ladder working on the antenna, there were some flashes far off and distant thunder, I could draw arcs from the coax F connector to the mast pipe. This was before the ground rods were connected. I'm very glad I didn't touch the mast and F connector at the same time at the top of that ladder! What are the chances of all this happening at the same time? I should go buy a lotto ticket.
@@MrCarlsonsLab When I built my first receiver, a transistor super-regenerative short wave radio kit, it needed an antenna. I used 30 feet of magnet wire strung on small hooks under the eaves of the roof across the front of my home. Since I lived in tornado alley, severe thunderstorms were fairly common. The first time I saw a storm approaching, I disconnected the antenna from the radio so I could attach it to the air duct which I used for a ground. Before I could attach it to the duct, there was a flash of lightning more than a mile away, which I saw and felt at the same time. This demonstrated to me that you don't need a direct lightning strike to generate some impressive voltage spikes in a 30 foot wire antenna. Static / corona is another thing that can build up on elevated metal objects during storms or from falling snow, as you have shown in another video.
@@MrCarlsonsLab ok, fair enough.. 😊 I wouldn't want to see any of the equipment in your lab being damaged. Or you for that matter..
Thanks for what you’re doing! Education and entertainment, all in one. I was a little concerned to see your antenna has an independent ground. When a lightning bolt is close, the difference in ground potential, given their proximity to the strike, can be hundreds of volts or more, with a lot of current behind it. Building codes require all grounds be bonded for this reason. I was also surprised to see the 369 antenna doesn’t use high impedance balanced line. Why is that?
A few years ago Paul demonstrated a transmitter he built and how energy from that could be monitored (seen and measured) on another receiving antenna as such. That's what purposed my subscribing to this channel. Notwithstanding, I'd like to see Tesla's demonstration of wireless electrical transmission duplicated, specifically with his "hair pin" circuit, and how he achieved lighting "carbon button" single wire lamps he patented. Though I recommended it previously, I again reference "Secrets of the Cold War Technology "as a starting point for the curious minded. (Note please: The actual source for that work see Dollard.)
My brain is buzzin Mr Carlson! 👍🇬🇧
1Hz modulated noise/static sounds like an army marching. Might use it for some industrial music project :)
Almost 300K subs! huge community behind you and your top notch work!
Magicians Show. I expected a deck of cards any time.
I always wait for you latest video
I have a strange feeling , this is not the sort of guy that repairs iPhones at the mall
He could open your iPhone and turn it into a nuclear generator with things he has in the refrigerator
And pierce your ears at the same time.
@@martymcgill1312 "Works nice now, has reception everywhere, even in the middle of the ocean .. but the tube sticking out of the back makes it a little weird in the pocket."
Please attach your antenna to one of those old vacuum tube radios you restored and try AM and SW with it
That will happen soon.
15:50 - Is the brightness constant no matter how many LED's you add? If so, your 3-6-9 is acting as a constant current source!
Camera AGC. Also leds hard to vary brightness by current (one of reason to using PWM for that)
Totally awesome!
As a kid, my cb radio would cause three decorative incandescent (12v) lights to glow dimly when i would transmit, eventho the bulbs were not plugged into anything, they just had some twin lead wire attached to them.
I have been intrigued by ground rod's for some time now, as far as I know, it's usually just a copper rod hammered into the ground but I have a theory where if the ground rod was insulated with just the tip exposed to ground at the deepest point, I'm expecting a greater difference in potential as the ground point would now be grounded in a more negative point of the earth and thus providing a much stronger signal. My thought process is that the bare copper rod would follow normal Electric rules and thus conduct at the path of least resistance... By forcing it to source ground at a deeper point, you should effectively be increasing the power of the antenna...
It's an experiment that I have been wanting to do but I just haven't got around to it yet....
I really wanted to see the open circuit voltage of your antenna but you didn't end up showing it...
I wonder what voltage will be present during snow fall? Or rain fall?... Maybe a future video lol????

I'm currently staring at my shack's ground rod. I fully blame you.
At least it has potential. (See what I did there)

Ground rod's what? Noun missing.
Well this post quickly went deep south!
Wow ,the real free energy
I've finally gotten up the gumption to repair my Bauer 707 and get it back on 75M AM.
The 707 is a nice transmitter!
My favourite experiment is using a microwave transmitter to light up a fluorescent tube. But this is good too! :)
OK, so when you do get into the explanation of this antenna, I'd REALLY like to hear the hows/whys of what led you to this particular design and even more importantly-how it works :)
Absolutely fascinating Paul ! Another great video from you. Thank you.
It's weird to think of the "energy" being coupled between the random coil and the radio is actually extremely low energy photons coming out of that little random coil then inducing electrical "movement" inside the radio's antenna ferrite coil.
Your 3- 6- 9 antenna seems to work extremely well ! I need one !!
Norm KC1VY
Cool, I bet you get loads of stations with that.
Thanks
Bad ass!!!!!
So Cool ! Thanks Mr. C.
That antenna is a beast ;-) It performs very well. I guess your first tests put a smile on your face, and maybe you were suprised, too? 73 and all the best, stay healthy de Olaf, DK6KF
A great demonstration of the basics of radio. It would also be possible to demonstrate the operation of the detector receiver. Be careful with that wires - static electricity can shock your hand.
