Default Yaesu FRG-7700 Tuning dial mechanical fault

The tuning dial of my Yaesu FRG-7700 receiver will not rotate beyond
about 780 Khz.
Is that easy to fix?

I suspect that the tuning mechanism is a geared assembly. Manual he

If it is mechanical, it may be jammed on something caught in the gears, or perhaps the gears have slipped. Otherwise, you may need to replace the part.
