Adding 10K resistor to basic ujt oscillator gives voltage-controlled variable-frequency oscillator. With 0.68 mfd for C, d-c input voltage range of 0 to 30 V gives 670 to 4,550 pps. With 0.2 mfd for C, same input range gives 220 to 1,400 pps. Not intended for use where linearity is important.-B. Strunk, Voltage-Controlled Variable-Frequency Oscillator, EEE, 10:12, p 28-30.
