Chris’s transmitter uses only 17 parts and has a range of 100 feet indoors.

The goal of this project is for me personally to learn a little more about fm transmitters and fm bug making (may the HAM radio gods bless me in this pursuit). The ideal outcome of this project is a very small and full functional FM transmitter that we can stick into a plastic mint box.

In order to be able to build this, we’ll have to learn a lot about amplifiers, LC oscillators, mixers, antennas and FM. This project assumes you’re already comfortable build your own PCB boards.
