I stumbled across a relatively simple FM radio transmitter online.
I wanted to understand how it works (it is called "super simple" on the website), but several hours I have nothing but a vague understanding.
I believe R2, L1, C3 form an oscillator, and then the transistor Q1 is used to modulate the signal. C1 would just be used to remove any DC offset. However, this leaves R1, C2, C4, C5, and R3 and, for these components, I have no clue what they do.
Could someone please explain how this "super simple" transmitter works?
