Under no circumstances should the rotor and stator plates touch each other!
Remove the cloth carefully so that no metal chips fall into the device.
Clean the capacitor between the plates with a contact spray so that there are no more
aluminum filings inside.
2.2 Mechanical adjustment of the VFO variable capacitor
Turn the unit, so that the open variable capacitor is easily accessible from above and the
tuning knob at the front.
Loosen (do not unscrew!) the two grub screws of the gear wheel on the axis of the rotary
capacitor. The tuning knob must be turned slightly, as both screws are not accessible at
the same time).
Figure 5
Position the variable capacitor by hand so that the rotor plates are fully turned in
(maximum capacity of the variable capacitor), see Figure 6).
Figure 6
Turn the tuning knob clockwise to the right stop. The variable capacitor must not rotate,
otherwise you have not loosened the grub screws enough.
