I never had luck operating an Omni-C from a storage battery. It may be that
the voltage from the battery is not high enough to permit proper regulation
in the rig.
What you are seeing may be a problem with the frequency changing, as you
say, or with the display changing, or both.
Try running the rig from a real supply and see if that doesn't fix the
