Spark Gap Transmitter

[@petesteslachannel334]

That is very cool. Especially that antique spark gap. You were lucky to get that. With you mentioning the transmitting frequency of your coil, , it makes me wonder what my horizontal coil was putting out. . The neighbours probably had Pirates of the Caribbean coming from their appliances !

that is amazing. great setup, good videos!!!!

Very nice work Garry. on the SPARK GAP TRANSMITTER". I would bet the new technology could learn a thing or two from the word, "RELIABILITY". I hope to make me one also soon. This is history in its purest form ever shown and demonstrated. Hope I am able to get some "period correct parts" to keep the unit "period correct". Keep up the great work using videos also.......

Thanks! Garry is very good at taking modern technology back to its roots, and showing it in a way that is both entertaining and educational.

[@victoryfirst2878]

@@DavidSkelhon So you are not Garry ?? Please explain fella.

[@DavidSkelhon]

Garry is a good friend, and I am the video producer. We both have a passion for science and education!

[@rockpadstudios]

it is amazing how creative they were without the theory to drive the designs (in many cases).

[@fidelcatsro6948]

they even had electric pulses used to cure body ailments and disease back then, powers that be today has called these quackery unfortunately, i still believe some of them actually worked

Super interesting video, those are some beefy coils, must have taken hours to fully wind!

[@mikea1668]

Would love to see the working receiver in use.

[@DavidSkelhon]

That would be interesting as I'm not sure what the operator would actually hear. At the time, there were no vacuum tubes to create a beat frequency, so we wouldn't hear the CW tones we are familiar with today. I believe there were natural semi-conductor materials available that would have worked in a similar way to modern diodes, and I suspect the operator would have heard clicks or raspy tones generated from the intermittency of the spark gap.

thanks for sharing

[@fidelcatsro6948]

yum yum looks like its based on a glorified Tasergun circuitry we have today 🐱👍🏿

[@АнтонВасильков-с4ь]

Could you please name reference books mentioned in video? Nevertheless - much kudos for presenting this monstrous beauty

Handbook of Technical Instruction to Wireless Telegraphisis, 7th Edition (first edition 1913), authors Dowsett & Walker, published by British Wireless Marine Service, Marconi Company. High Frequency Apparatus, by Curtis Gorman, Henley Publishing (New York) 1920. Hope this helps!

those were great times to live in where new ideas and technology were being invented and discovered

[@dragon72tube]

Tesla technology wow

[@jesseamaya4413]

Isn't a spark gap transmitter illegal to run now? In a Faraday cage? Doesn't change the fact that it's cool as all get out.

[@DavidSkelhon]

You certainly wouldn't want to connect it to an antenna.

[@fidelcatsro6948]

fcc wont chase after you as long as you dont point one probe outside the window and the other connected to the metal water pipe...cops might think you own an illegal giant taser though

[@BritishEngineer]

Isn’t it too low frequency to be anywhere near radio frequencies?

[@DavidSkelhon]

No, there are specialized radio communications at frequencies that would be audible if turned into sound. That is, below 10kHz.
