Further to my earlier, now that I have my manual, notes and coffee in
front of me, each band has a crystal and series inductor on the XTAL Osc
& L.O. board, page 4-14 & 4-15 in the manual. The inductors can be
tweaked for each band. These are L12 - L21.
The BFO alignment procedure is on page 4-23 and 4-24. This alignment
must be done first and in the order stated in the manual.
I usually allow the radio to be at operating temperature for about an
hour before starting adjustments.
Just correcting one band or frequency is ill advised as there are many
inter-related adjustments.

I would first check and adjust the BFO oscillators using the procedure as
described in the manual. Then check each band to determine if it is one band
or all bands and the amount of error.
This has to be done with a known accurate frequency counter.
If all bands then adjust the Master Oscillator to correct the error.
Typically +/- 50 Hz is about as good as one can expect.

I have an Omni VI+ that displays the incorrect freq readout.
My owners manual does not give any indication on how to correct this.
Can someone give me the correct way to correct this?
An example is if you wanted to be on 7200, you would have to tune to
7200.19 to be on the correct freq.
Thanks!
