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

It would seem you are in a great position to tell us :)

Fair comment! I now have the cover off and it looks like I will
need to remove the front panel.

It's interesting because the tuning works normally up to
about 800 Khz.

Not having such a device I cannot help with data but if you can see the
mechanism perhaps turning it back a bit might show the cause ?

The mechanism is in the VFO box and I can't see a simple way to
remove the cover.
