Questions about designing an FM transmitter

Hello.I have 3 question.
1-have everyboddy a tutorial & analysis about fm tasnmitter(LC oscillator)with description of each section?
2-How we can increase stability of a fm transmitter(frequency stability)?
3-Can a crytal oscillator (for example colpitts) be replace with LC tank in fm transmitter?

1- https://www.edaboard.com/viewtopic.p...760&highlight=
2- Yes, by maximizing the loaded Q of the circuit
3- Single crystal will make it very difficult to FM modulate unless you use a PLL system

you can moduate the pll in the loop filter.then there is no frequency problem.

OK.Can u show me a complete project?
