Im making a traking device **broken link removed**
i am very bad at making the coil (L1).
I have two parts:a inductor multilayer 0.1uh,conformail coated RF choke 0.10uh.
Whould one of them work insted of L1
thx :?: :!:
I don't see how that circuit can oscillate without an emitter resistor or choke. C4 is supposed to provide the positive feedback but can't with the emitter grounded as shown. This is the only one of his many FM transmitter circuits that doesn't have an emitter resistor.
