Nice colab. I really enjoyed the content. You're both serious scientists, but you're both pretty good entertainers. Hey, I got an hours worth of high quality "Edutainment" (yeah, like that's still a word). Like I said, you're facts are accurate (Except that part about the hazards of extremely low concentrations of ozone). But I digress. as a sacrifice on behalf of you both to the almighty algorithm you both get a like and a sub. Of course now that subscriptions play a role in monetization, and everyone implores you to do so, notifications from KZbin are now completely meaningless. I'm guessing they factored that in.

Recent discussions have lead me to confirm my hypothesis that the energy and antenna used are simply for signal strength and broadcast range? I mean, should you use a simple diaphragm and length of wire, you could broadcast to a speacialy designed receiver with extra amplification abilities, short distances, like centimeters, but that the idea, and ability are sound? Pun intended.

[@LandNfan]

This is why shipboard radio operators in the early days were often nicknamed “Sparks” or “Sparky.”

[@Cyberplayer5]

Related to the subject of radio the building on a ship that housed the transmission and reception equipment was called a "radio shack".

[@karlharvymarx2650]

A useful but very simple transmitter can be made with a relay and a capacitor. If I remember correctly, the electrolytic capacitor is wired in parallel with the relay coil, and the switching part wired so that when the relay turns on, it shorts the capacitor (and battery). The terminal of the moving part of the relay is wired to the water inside a PVC pipe. When powered on the combination of the capacitor charging and the inductance of the coil prevents the relay from turning on. Once charged, the relay turns on and discharges the capacitor, making a little spark inside the relay and radio waves which make their way into the water. The shorted relay turns itself off and the cycle repeats at a rate proportional to the capacitance. If an AM radio is tuned to best reception and then swept over the pipe full of radio emitting water the pipe can be traced. I think I powered it with a 9V battery and it was enough to trace a 1" PVC pipe 1.5-2 feet under sand from the well to the house 100 feet away. I'm not sure, but I think I remember it working okay if I just connected the antenna to the well housing even though that is grounded. If the relay doesn't buzz, try re-arranging the circuit, not 100% sure I'm remembering how I wired a circuit I first made by accident when i was a kid.

I am a physician with background in electronics. I am 70 yrs old and since I became an amateur radio in the early 1960’s . I have read all about Tesla, and the hex of electronics. During my many years of training in medicine I came across patients with great stories, some in their 80’s in the VA and other centers. In short: 3 patients, independently told me they worked on the USS ELDRIDGE. Clearing the entire “innards” of the hull and installing generators and RCA equipment that came in crates. One of them was working on the wiring. Heavy duty wires, porcelain insulators etc . There was a fine chain mesh, like “mosquito net” loosely going around the outside of the hull (in the water) that covered that went around the entire ship hull & was bolted to the hull on the sides (ground?) . Several weeks later a pre assembled series of 3 sets 10 foot coils mounted in a 5 “ cylinders mounted in X,Y,Z axis. Each set of the 3 coils mounted in XYZ configuration were installed at the back outside deck, another set on top of control deck and the third on the front of the ship. Each individual coil had an independent primary connected to its own power supply . The bases of each coil was about 3’ from the other two. This is all I could get. I can’t make sense of this configuration using my very basic knowledge of physics and resonating circuits. Just using the right hand rule, the fields of each set of 3 coils would cancel each other. I gather that each the sets of 3 coils were likely connected individually. Using high voltage in 1 set of 3 coils mounted this close would no doubt cause arching to form. Now what do you think the 3 sets of 3 coils far enough from each other would do? For sure some time of resonance wound be achieved no matter if arching between the coils happened. If each individual coil was activated individually within miliseconds of each other they each would work independent of each other on one set. Then how would the 3 sets of 3 coils do anything, even if they were used in something like a phased array? From the information above, I gather that the “Philadelphia Experiment” at least was tried. The stories associated with it may all be made up. For sure this setup. Was mounted on the USS ELDRIDGE. I am very interested what you & the Plasma Channel guy make of this configuration. I asked a PhD physicist in the early 80’s what he thought. The only thing he could suggest is that the coils mounted in X,Y,Z configuration may have had something to do with our 3 dimensional universe, but even then this was just a wild guess… PLESE GET BACK TO ME ON THIS MYSTERY. Are there other circuits besides possibly “insect zappers”, where this coil configuration is used? THANKS IN ADVANCE.. Sergio

One can use the LO (local oscillator) built into all radios as a transmitter. Inexpensive AM radios generally use 455 khz while FM radios mainly use an 10.7 mhz. The local oscillator is actually a mini-transmitter that is used in radio circuits for purposes of selectivity and image rejection. By tapping into the local oscillator at a certain point, one can inject an audio frequency and piggy back the LO to actually transmit on either the AM or FM band offset 455 khz higher for AM or 10.7 higher for FM. Thus if you tune the radio to 600 khz, you are actually transmitting on 1055 khz on AM. Likewise if you tune the FM radio to 88 mhz, you are actually transmitting on 98.7. Unfortunately , the LO has a very weak output and that is just one of the limitations of using a radio's local oscillator as an emergency transmitter. By adding an antenna, one can transmit a few feet to maybe 200 hundred feet under most ideal conditions. Another limitation is the possibility of getting a shock if you are using a house power instead of AA batteries. Another drawback is the possibility of shorting out your radio by attempting to use it as a transmitter by tapping into the wrong part of the radio circuit. But anyway, interesting video nonetheless...

[@jmikronis7376]

I like your answer on how to obtain RF out of a radio. A very tiny loop of wire next to that local oscillator is a safer way of extracting that energy. Then, powering the radio on and off will become your Morse code signal. With the way everything seems to be monitored in this world, it would get you some attention.

[@AtlasReburdened]

You know, If you just use a rotary spark gap to get consistent spark timing, and put one element on a rocker(or have really good rhythm) you aren't limited to morse, you can send straight up digital data. And on the subject of emergency transmitters, believe it or not, you can just use a car battery, two wires, and a metal file. Wire-Pos | Neg-wire-file Just scrape the Pos wire against the file very quickly to send hundreds of tightly packed bursts of broadband emf per stroke.

Spark gap will come back in the form of ultra-wideband. It will work over short distances at very low power. But every node in an ATM mesh Network will be a transmitter receiver using ultra-wideband. The carriers will be high and dry looking for a ball player. The packets will be able to make hops three orders of magnitude faster than current IP so no backbone will be necessary. And it will be connection-oriented not broadcast oriented.

I have that same spark generator. Is the ozone it creates actually dangerous? Also, I created a spark gap generator and detector based on videos by electroboom.... if I use two dipoles it does not work... if I use two monoples and connect the grounds together (with a wire) it "works" (the led lights up when I create the spark. Do I need the inductor and cap on the transmitter side? Why does it not seem to work with dipole antenna? Is it working when I use a wire as a common ground or is it just using the wire to light the led?

[@jmikronis7376]

I’d put a very tiny loop of wire over the local oscillator to extract RF energy from it. Have that wire extend out as many feet as possible. It’ll create a radiating antenna for that energy to disperse. Use the on/off switch as a keyer to do Morse code. That’ll get you some attention.

[@bassdowg]

Spark gap xmitters are now illegal bec the signal is very rich in harmonics that is very broad accross the entire radio spectrum, LF through HF and higher... spark gap xmitters emit damped waves, how ever in extreme emergency situations one benefit of being rich in harmonics is when used to send distress signals your signal stands a very good chance of getting heard because of sever RFI it will cause through out the Bands of frequencies used by all radio services, (this is the main reason why such xmitters are now illegal) but you have to knw how to send SOS in morse code, rescue responders will know that you are in distress some where out there in the vast pacific if you knw how to send this three morse characters.

...Yes, but how do I make a primitive radio transmitter? If I were on an uninhabited island, rare as they are, recalling this video would leave me only slightly better off, since IMO many of the practical details are omitted. 100 feet isn't much; what does it take to make it detectable for planes passing overhead? How much energy should I be pumping into it? What angle should the antenna be at? How do I adjust the antenna to the length with the best resonance? Would putting in a reflector improve things?

[@BlueprintScience]

Ships still to this day use spark gap radios for emergencies if I recall - it's not outside the realm of possibility. As per practicality, I was just trying to make an interesting video; it's not practical. Making a signal fire is practical.

[@Cheburashka_420]

I am 2 minutes in and I have decided that you are the most interesting person I've seen to date.

[@jeffmccrea9347]

Using a CB antenna on your project, while better than nothing, will pretty much tune your transmitter mainly into the CB band, which is woefully lacking an audience on a desert island, and maybe a few harmonics on either side of it at progressively lower signal strengths as you move farther and farther away from 11 meters. Any other hash that your spark gap transmitter makes will be choked out pretty much on every other frequency. Breaking open the center loaded coil and making a "long wire" antenna out of it's wire would create static interference at higher frequencies, (shorter antenna), and with more harmonics to create a more attention getting signal across a greater number of frequencies. It would be best to aim for the aircraft band, (108 to 136 MHz AM), as the possibility of any aircraft flying overhead would hear you on their AM frequencies as your spark gap transmissions would be more apt to open the aircraft band's AM squelch. Most boats today use VHF FM frequencies. While the FM VHF marine band, (166 to 174 MHz), is relatively close to the aircraft band, the FM channelized bandwidth, (25 MHz per channel), and it's associated FM squelch circuit would wash out / block out your signal from ever breaking into it's receiver. Very few ships, except for large ocean going freighters and cruise ships, at sea still use the HF SSB 6 MHz marine radios anymore due to their $4,000.00 to $6,000.00 price tag and very large, low frequency antenna compared to the $150.00 to $200.00 price tag of a good VHF FM marine radio and it's associated, much shorter, less wieldy antenna. While the HF SSB radio would be ideal to receive a spark gap signal, being that SSB radios use a BFO, (beat frequency oscillator) to hetrodyne with the carrier free SSB signal, to be able to hear intelligible human speech rather than something akin to Donald Duck is much more appealing. Your relatively short, "long wire" antenna made from the CB antenna's center load coil, might only make it a couple of miles out to sea at best as opposed to an aircraft's one to eight mile vertical height over head. You might also want to scare up something conductive such as a piece of wire, salt water soaked rope or what have you to connect to the spark electrode opposite from your antenna electrode. Thrown into the water or spiked into the ground, if you can find a piece of metal to use, to act as a ground plane would help to increase your range a bit. Every little bit helps. Keep plugging away, (pun intended). Channels like yours are very beneficial and educational. Thank you for your service.

[@margraveantonov3054]

Why do u need a tube to access higher frequencies? Can't u just use a shorter antenna so u have a short wavelength and instead higher frequency? I dont get it pls help :(

[@BlueprintScience]

Margrave Antonov, Tubes (and later transistors) were used because they are stable and can generate more complicated signals like AM and FM. Without modulation (which spark gaps cannot do) there would be no radio beyond Morris code. Also, like spark gaps are “noisy” in the radio frequency spectrum. Without a stable generator like a tube, only one could transmit in an area at a time.

[@dkdyker]

interesting, the signal will allow the LED to continue to light after the switch is closed on the transmitter. Is there a cap already charged to begin with ? Have you tried to have both ends of the bolts of your coherer driven into the earth and see if this works just as well. I have tried something similar and the earth will carry the signal to enable the circuit to be closed.

Spark gaps are the secret ay. What is goin on now that the electricity built up the charge required to ionise air before clearing a spark gap. Is it an altered wave front? Or the spark gap kind ‘tunes’ the energy to its characteristics when the spark was created?

[@BlueprintScience]

I'm not sure that I understand the question, but I'll try to answer the best I can. A spark gap is basically 2 antennas. Charge will gather on them as the electric field between the two electrodes will increase until the field becomes strong enough to arc. The arc is continuous because it happens at such a high frequency, the air stays ionized the whole time. Any tuning of the gap is done by external circuitry.

Fortunately EMERGENCY SITUATIONS have legal allowances for operating equipment not otherwise allowed. Such as, using a spark gap radio to signal help. Or if you do not have a ham radio license, you may use ham radio equipment to notify others of an emergency situation... IF NO OTHER PRACTICAL MEANS EXIST.
