- The Marconi spark gap transmitter is a type of AM radio transmitter which requires no amplifier. Let's see how it works.

These basic concepts are extremely useful to know and study. Yes, we can digitize everything and control high power with FET's but what is the failure mode of a broken contact? Why do I see a spike of RF when making and breaking contacts? What controls the frequency of the interference? All these answers are second nature when you know how things were done in the past. Great content! Thank you for making this.
wonderful explanation.
In my undergrad I had made a spark gap TX with oscillating Relay and Transformer in step up config followed by a zinc sulfied crystals based coherer for detection of radio signals. it was noisy and unreliable but it works.
Thanks for a great informative video.
Cheers !!
Amazing job!
You can build a great spark gap transmitter using a car distributor coil, a replay and a 12V battery!
Thank you so much. watching this for my today's 8th sem final exam revision for telecommunication. 😅😅
Great again
i thought i was the first one who thought of the spring-loaded switch, nice
Hello sir, i have a question
So now as you removed c2 we are not generaring sine signal but rather it is been generated because of C getting charged and discharged so instead of sine signal now we jave pulse signal right?
Please reply , and thank you for this series😊
Is this the same Marconi, who was given a Nobel prize for an invention of telegraph.
Well not really. It was Nikola Tesla who was even awarded a Nobel prize posthumously. As N.Tesla stated; I'm not worried, that my ideas and patents get stolen. I'm concerned they don't have their ow.
Yep, Guglielmo Marconi, the very same; the man who had Benito Mussolini as Best Man at his second wedding! Kind of like the Elon Musk of his day; got really lucky to snag other peoples' great ideas and then ran with them without the slightest compunction.....and if progress happened to require BSing the government (in Marconi's case, the UK Postal & Communications Department), then so be it.
The same fraud (marconi) used 18 of Tesla patents in his radio that crossed the Atlantic. Tesla said he used his patents and device because Marconi's patent was flawed and could never work based on its design. He also said that all radio engineers got it wrong by trying to broadcast millions of volts through an insulator (air).
Early 20th century. Not early 19th century/
