I constructed this VHF back II VCO to work with FM. I simulated this circuit in MultiSIM with initial condition set to zero and it works. Once I implemented into hardware, it does not work and refuse to give any oscillation, any idea what went wrong with this design?
Both C9 and C5 are trimmer capacitor.
