[Elecraft] Transverter calibration

[G4GNX]

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?
