  • Notes
  • AM radio for external antenna:
    • LW: 150 - 420 kHz.
    • BC: 420 - 1620 kHz.
    • SW1: 8,1 - 5,9 MHz (37m - 50m with bandspread 49-50m).
    • SW2: 9,67 - 7,06 MHz (31m - 42,5m with bandspread 40-42m).
    • SW3: 12,5 - 9,43 MHz (24m - 31,8m with bandspread 30-31m).
    • SW4: 15,8 - 11,6 MHz (19m - 25,8m with bandspread 25m).
    • SW5: 19,3 - 15 MHz (15,5m - 20m with bandspread 19-20m).
    • SW6: 23,08 - 17,65 MHz (13m - 17m with bandspread 15-16m).

    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: 9702-05 (7Ω, with soundwave diffuser).

    Dial lamp: 2x 8097D (E10, 19V/97mA).
