FM Superregenerative Receiver
using only two transistors
Building an AM receiver is a simple project for a beginner, but building an FM receiver is rather trickier. However, with a little ingenuity we can get away with a very small number of components: our superregenerative ‘Audion’ receiver uses just two transistors, two coils and a few capacitors. A ‘mini’ project in the true sense of the word!
