Clean the switch contacts for the RIT control. Or at least cycle it rapidly
several times and the problem will go away.

I recently bought a TS-120S that every so often will just jump 4-8khz off
frequency without touching knob. This is not a gradual drift but a direct
jump. I have removed the VFO and removed VFO shell case and tightened all
screw backup as suggested in kenwood service bulletins, but it is still
doing this. Any ideas or help would be appreciated from the technical
people out there. 73 Ted N8GPQ
