On the TS850 the RIT is a variable resistor not an encoder (It's
VR6 on the SW_A board). It is normal for this arrangement to go
to an ADC on the processor which then controls the synthesizer
- adding or sutracting a nominal amount from the frequency set
by the main dial.

Therefore RIT will only be as good as the stability of the pot (mechanical
and electrical) and the stability of the supply voltage.
