On youtube there is a video of a guy which made the same circuit and he's able to disturb a modern FM radio.
Unfortunately i don't own an oscilloscope.
In anyway i have made a classic oscillator with capacitors, coil and transistor, and this new circuit works like a charm. About the circuit: i...
Hi Audioguru,
I've grabbed a variable capacitor from an FM radio (this capacitor should be more appropriate), but is provided with six pins (three above and three below).
Which i have to use? The four in each corner are named from C1 to C4; i have tried to connect C1 and his middle pin, also C3...
Many thanks also to you for the reply, albbg.
I found this argument very interesting, but we have to assume the fact that i am a newbie about RF.
I work as computer technician and my interest for electronic started some years ago. Since some months i also have interest for the RF part of...
Hi Barry,
The fact is that on internet (also on youtube) the circuit claims to work near vhf frequencies.
What determine the working (or range) frequencies of the circuit?
And why this circuit relies on a single IC instead of a classic oscillator with transistor?
Thank you.
Hi, i am a new user, my name is David and i'm from Italy.
I'm writing here to get help about a circuit which i made, for instructional purposes.
The following pic is the schematic:
**broken link removed**
The IC is a 7404 and the capacitor should be a variable tuning capacitor between 3 to 20...
