For months Iíve been looking for a simple FM BUG project, the ones online require inductors which you either have to acquire or build, if you donít have a LCR meter it becomes rather hard to get the circuit working, specially if youíre a beginner without an oscilloscope! Ė Sometimes they donít even tell you which inductance is required and you have to calculate an estimate, which is the main reason why many high frequency RF projects fail in the first place. This circuit on the other hand performs pretty well, even if youíre manipulating the board or touching the coax it will stay within the tuned frequency (unless you touch the transistor or timing capacitor!).
