Sensitive FM Transmitter
Simple and easy build of FM transmitter circuit. The circuit only require 2 transistors.
Typically the default for the capacitors model is ceramic, preferably the npo 1% type or equivalent. However , generally almost nothing critical right here. Work with any capacitor you’ve laying arround, but DO NOT use any electrolytic or tantalum capacitors. Only in case you intend to apply this circuit outside the home you may need to use capacitores which have more temperature stability.
