しなければならない欠点がある。However, in the above-mentioned conventional super-hetero gain receiver, the reception frequency is not the local oscillation frequency + or - intermediate frequency, and when changing the reception frequency, the frequency of the local oscillator 4 must be changed. However, when receiving different radio waves in the same band at the same time, there is a drawback that a plurality of the same devices must be used.
