PURPOSE:To obtain a most appropriate signal in a receiver and a high frequency converter of a double tuning system or the like. CONSTITUTION:When a fixed oscillating frequency of a 2nd oscillator 7 is deviated depending on various conditions on the assembly to the inside of the oscillator main body, since a frequency of a disturbing wave is made close to the ideal band by storing an offset in matching with the deviation to a memory 15, a very effective disturbing wave is injected to a video carrier frequency. |
