Hi Alan,
that's true. What I did (was off a few hundred Hertz, too) was to
calibrate the main reference oscillator with REFLOCK enabled from a
stable 2 m source. Worked well.

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.

I built a K3S a few months ago and I've installed the K144XV 2 metre
transverter into it, along with the K144XV Ref lock option.
Although all of the main K3S calibration is OK, I find that the
K144XV is about 200Hz off nominal frequency, certainly in the 144-146
MHz segment.
The manuals mention calibration being automatic, so I can't find any
reference to adjustment where the frequency is incorrect.
Anyone any ideas how I can get the transverter on frequency across
the band?
