[TenTec] How to adjust frequency display on OMNI V?

I have an Omni VI, so to apply this to the Omni V assumes that it is 
very similar to the Omni VI. I don't know this for sure, so beware.

In the Omni VI the "VFO" is a combination of a PLL synthesized VFO and a 
crystal oscillator (one of several, selected for each band) both that 
VFO and the crystal oscillators are supposed to be locked to the 
reference oscillator. The BFO is NOT locked to the reference oscillator. 
If the reference oscillator is properly adjusted, the frequency 
calibration of the radio can still be wrong due to BFO not being just right.

There are a lot of rigs that have ALL of their oscillators locked to a 
single reference oscillator, and with them a single adjustment will get 
them right on for all bands and modes. They will often have more phase 
noise than the Omni series radios too.
