PURPOSE:To secure reception of any kind of the reception signals in a good condition by securing the presetting through simultaneous combination of the signal process lines suited to the quality of each reception signal in correspondence to the preset of the reception frequency. CONSTITUTION:To secure the tuning control for the reception frequency in case the tuning frequency and signal process lines L1-L3 are preset in combination, manual change-over switch 11 is connected to terminal 11a. And up-order 14 or down-order 15 is given to up-down counter 13 to vary the output frequency of local oscillator 16. Then line switch controller 9 is operated so that the input signal of antenna 1 is set so as to pass through optimum signal process lines L1-L3. After address designation 22 is given to tuning frequency code memory 20 and signal process line switch control memory 21, the presetting completes through operation of mimory order button 23 and 24. |
