Abstract
PURPOSE:To secure the accurate display whether the received SSB signal is in the upper or lower wave band, by providing two filter circuits possessing the higher or lower signal pass band than that of the IF amplifying circuit to the output side of the frequency converting circuit and then using the outputs of these circuits. CONSTITUTION:Filter 10 possessing the higher signal pass band than that of IF amplifying circuit 5 is provided to the output side of frequency converting circuit 3 along with filter 13 possessing the lower signal pass band than that of circuit 5 each. Then circuit 10 operates to the SSB signal received through antenna 1, and the fact that the received signal is in the lower wave band when display unit 12 operates via driving circuit 11. While the received signal is displayed as the SSB in the upper wave band in case circuit 13 operates to the received signal along with the actuation of display unit 15 given via driving circuit 14. Thus the accurate decision is secured for the SSB signal by giving the coincidence between the received SSB signal and the switching state of mode change-over switches SW1 and SW2 each.
