Abstract: An electrical fine tuning system for a UHF television tuner utilizes a voltage variable capacitor for adjusting the operating frequency of the oscillator. The capacity of the voltage variable capacitor is determined by a potentiometer that is mounted concentrically with the selector shaft and serves as a fine tuning control. An automatic frequency control voltage may be applied to the voltage variable capacitor used for fine tuning or to a second voltage variable capacitor. Circuitry is provided for extending the tuning range of the voltage variable capacitor when a single voltage variable capacitor is used both for fine tuning and automatic frequency control, and an improved mechanical construction is used to couple the voltage variable capacitors to the oscillator.
