Marconi Spark Gap Transmitter (4-Analog Electronics)

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

Aaron Danner is a professor in the Department of Electrical and Computer Engineering at the National University of Singapore.

You're the best teacher I ever had and it's free

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 !!

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.

You can build a great spark gap transmitter using a car distributor coil, a replay and a 12V battery!

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😊

Thank you so much. watching this for my today's 8th sem final exam revision for telecommunication. 😅😅

This is the greatest RF course in the world. Please I want you to further this course and also antenna 📡design. I don't mind buying it on udemy pls I beg you. You are a very great teacher

Its it an AC signal or more a pulsed DC signal? Wouldnt current still be flowing in the same direction?

i thought i was the first one who thought of the spring-loaded switch, nice

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.
