Wiring Schematic diagram

Simple but high efficiency of this schema is a Colpitts oscillator for VHF. Ideal for higher frequencies above 50 MHz, Colpitts oscillators are used for VHF parasitic capacitance of the schema is in parallel with the feedback capacitance desired and causes no undesired spurious resonances which may occur with the Hartley oscillator.

The schema above is a VCO FM, it is a grassroots project with grounded feedback from collector to emitter. A Colpitts oscillator is a series of designs for electronic oscillator diagram using a combination of an inductance with a capacitor to determine the frequency.
