This guy is an absolute genius. This is the most detailed, accurate, intelligent and informative electronics channel you will see on KZfaq and in real life. I have watched all of the electronics channels on KZfaq 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

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.

Very impressive that the antenna picks up enough signal to light those LED's.

1Hz sounded like the "alien signal" in Contact :) That was a great demonstration!

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

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.

Can’t wait to see more with the 3-6-9 antenna. Maybe baluns and antenna tuners.

Im really digging this format. Thanks.

So awesome that Mr. C uses classic vintage and custom built equipment.

Excellent discussion of coil coupling. And 'no trickery!'

Paul, I am so envious of you! Well done, you earned the bragging rights!

1 cycle out sounded like the "alien signal" from the movie contact.

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!

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.

Equipment I could only dream about. And if I could just use 10% of their features I would be satisfied enough.

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.

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.

Sorry this video had to end! This was great!

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

I must admit that I cannot watch this video unless I have a great dinner ready and a few good beers... Semper fi!

you always a fun time for me Mr C! Never to old to learn something new

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 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.

Very cool! I didn't realize it could also work this well in the AM Broadcast range.

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

Almost 300K subs! huge community behind you and your top notch work!

Fascinating demonstration, and very well explained!

Well, there you go, it a great example of inductive coupling.

I just love your videos. Particularly your great attention to detail.

I'm retired but I've done nearly everything in electronics during my career except....radio ! I enjoyed the magic show !

Very interesting! Looking forward to learning more about your 3-6-9 aerial.

I have one of those HP function generators. Neat piece of kit.

Phenomenal. Thank you.

Excellent as always!

Great video Paul..Learning all the time..Fascinating how induction works..Thanks for sharing..Ed.uk..😀

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

Totally awesome!

I cannot wait for ur new antenna vids!

A wealth of knowledge. Looking forward to the next vid👍

So Cool ! Thanks Mr. C.

😲 Very neat stuff! Thanks!

Actually 3 thumbs up. You are doing some of the things i did when i was 15. Memory lane 😁 with some new stuff!

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.

Nice WWVC Rx. Nice Variable RF coupling transformer demo!

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.

Nice video, thank you :)

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.

Always amazed at how good your videos sound.

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.

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.

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.

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.

amazing!

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?

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.

fantastic demo 👍

Wow that's really neat, now I need to try some LEDs on my HF antenna :)

My favorite drink is beer but it’s only water when attending a Mr. Carlson Lab.

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!

Tremendously impressive 👍👍👍

Nice demonstration!

I love this channel.

Thank yóu for sharing

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.

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! 👍🇬🇧

Nice demo!! I've known this could be done for some time.

I think a video on frequency standards (and some low end/hobby level alternatives) would be awesome

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.

Hi Paul, excellent video as always thank you. I will now go and tweak my substandard antenna 🙄🙂

Hey... Made me think of the STS-75 Tether incident.. CHEERS! 🔥❤🔥

I always enjoy your videos.

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.

5:50 Delicious!! A nice box of candies,......

Wow ,the real free energy

Cool stuff Paul. 👍🏻

The 9:27 mark: Nicola Tesla at work...induction ALL HAIL NICOLA TESLA!!!

Super !

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.

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.

I always wait for you latest video

Interesting,... listening to the antenna tech.

Thanks

1Hz modulated noise/static sounds like an army marching. Might use it for some industrial music project :)

That demonstration was really cool and informational. Thank you, Paul. Is directionality a factor in the 3-6-9 antenna?

Magicians Show. I expected a deck of cards any time.

In my Sony STR-7045, underneath the tuning capacitor and its clear plastic cage there is some circuitry that you can access from underneath the unit. Just putting your hand in that area without any physical touching changes the tuning and thus what the radio receives and amplifies. It's wild!

You are amazing. I started to love inductors by the way. I design wireless leds.

Impressive

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?

Is this a traveling wave antenna? I've not seen the element coupling like this before. For TW antennas, they're terminated into a 50 ohm resistance, but you're not doing that. Is the inductive coupling of the isolated wire elements functioning as a type of matching stub?

Hi Paul, I guess that is "free energy". I knew a friend who lived near a very high power transmitter and he could run fluorescent lamps off a long wire antenna! Keep up the great instructional videos>

I've finally gotten up the gumption to repair my Bauer 707 and get it back on 75M AM.

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!

The magic of RF.

Cool to see around 15:35, a little bit of current sneaks through the LEDs with just your hand on the other side! I never considered how much power you could extract from just stray RF, I wonder how much you could get if you lived nextdoor to a transmitter.

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.

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...

Nice Video Mr Carlson's Sir.
