AM radio for external antenna:
By connecting a capacitor in series with the tuning capacitor, the total capacity change per unit of rotation is no longer linear but has the effect of stretching the chosen shortwave band when the tuning capacitor is turned in (at lowest frequency or highest meters). Loudspeaker: 9704-05 (with soundwave diffuser). Dial lamp: 2x 8045D (E10, 6.3V/320mA). Measurements including knobs left and right, width without: 590mm. |
