Best of Do-it-yourself FM Transmitters 1W FM Transmitter with 4 transistors This FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a ...

A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite stable and the output power is around 200 mW.

This is a short range transmitter with a transmission range of about 10-20 meters. Follow these steps and the FM transmitter circuit diagram, to make a super easy FM transmitter.
