VHF VFO circuit

The author has encountered a device which has both drifting and shifting problems. These two kinds of problems both have a high ratio. Although employed in the communications sector at that time, I had not solved the problems for months ( cobbler's shoes syndrome). A closer examination was given to only find that there is some debris below the rotor of main tuning capacitor. Under normal circumstances, the rotor of the capacitance is connected to the chassis through its frame. But a brass or iron triangle of ground or spring clip should be placed around the bearing in front of the rotor because the rotor must rotate.
