FM RADIO TRANSMITTER CIRCUIT
How to make FM radio transmitter circuit at home on
breadboard using one transistor .CIRCUIT DIAGRAM is in the link below. The circuit made by me can transmit audio at
frequency 90.7 MHZ on a radio. This can
be a small mini project for electronic students. Try it on your own and enjoy.
Things required:
*2N3904 transistor
*10pF capacitors x 2
*10nF capacitor x 1
* 1nF capacitor
*470 ohm resistor
* Condenser mic
*10k ohm resistor
*Copper wire for inductor
* 9v battery
How to make inductor :- to make inductor take 10 to 15 cm of
copper wire and wind it around a rod such that it looks like a helix. NOTE : 0.01H of inductor should have 5 turns of naked
copper wire .
I tried but unfortunately the transmitter is not working. What could be the reason?

ReplyDeleteA good drone transmitter should have a minimum of four channels for your aircraft. For better flight safety, you should get a transmitter with six or eight channels. Source to know more about quadcopter without a fpv.
