DALE,

is it off on one mode or all of them?

A man with one clock knows what time it is. A man with two clocks is never sure.

The BFO in the Omni VI IS NOT LOCKED TO THE 10 MHz reference oscillator. The BFO has several adjustments for the different frequencies used for USB, LSB, CW and FSK. Those adjustment interact, so it is necessary to do them in the correct order, and them do them again.

If that has an accurate reference you could use it and a general coverage receiver to listen to the beat between your sig gen and whichever oscillator you are adjusting. You will have to play around with methods of getting a sample of the oscillator and your signal generator at the right amplitudes to hear the beat nicely on the receiver.
