Summary

Not provided.


Description

An FM transmitter circuit. There's a few floating around but this circuit has an actual working amplifier stage. A few other circuits I've seen on here have Q1 biased in saturation mode which will greatly reduce performance. Do a time simulation and click on Vo to see the frequency of oscillation. For speed I suggest building this circuit in LTSpice instead. Perfect circuit to physically build and test out, should give you a range of 200-400 ft.
