Hi Don.
I am aware of the manual method of configuring the offsets and I originally
used that before I installed the K144XV Ref lock option. The Ref lock option
manual infers that all offset calculation is automatic when the menu is set
to REFLOCK and user calibration can't be undertaken. Is this not the case?

Alan,
Did you check the Frequency Calibration section of the K144XV option manual?
Look on page 19.
You can adjust the offset with the K3 menu XV1 OFS. The offsets for
each band segment should be indicated on the XV144 top cover. If you
have accurate frequency beacons available, you can refine those offsets
as needed.
