Bob, how can I find out what the differences among various MV89 are ?
thanks Goetz

Since the 10 MHz OCXO is in some way acting as a reference for the GPS in the
TBolt, there is a slight chance that the 5 MHz spurs could impact the receiver.
I doubt it would be a problem, but it's worth watching out for.

The MV89A is a 5 MHz resonator doubled to 10 MHz, it will have sub harmonics

This certainly explains what I saw when I looked at a MV89A on a
spectrum analyzer and saw a signal /below/ the 1

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
