Looking at the archive, I noticed that several months ago someone
commented that the Morion MV 89A was a direct replacement for the OCXO
in the Trimble Thunderbolt in the sense that the Thunderbolt PC board is
configured to accommodate it. However, I wasn't able to find further
I have a spare Thunderbolt and a spare MV89A and I am considering doing
the transplant. Before I tear the Thunderbolt apart, I have a few
1. Has anyone actually performed the transplant? (Does it work?)
2. Are there any significant drawbacks and advantages to the transplant?
I am aware that the MV 89A may pull more current on the 12 volt line
than the Trimble and that the original Thunderbolt cover will no longer fit.
