FM Transmitter (2017)

FM Transmitter with LC Oscillator and Feedback Circuit

Project Description

In level 2, we had an Electronics course. I wanted to learn how Transistors, LC Oscillators, and Feedback work in a transmitter. I built this FM radio transmitter circuit for testing. I did not have access to a breadboard then (that's why it looks chaotic). The mobile phone was the receiver. I kept it listening on a frequency with no other channel. Then I kept tuning the variable capacitor in the LC Circuit to modify the carrier frequency and kept listening to the receiver. After some tuning I was able to hear the Music on the receiver that was being transmitted.
