Hi Greg,

Interesting, but we're talking about 3mHz change in 10MHz. In all the
factors we have to consider, I think the impact of gravity on the
crystal can be ignored.

However there may be other more significant factors affecting the
crystal. Anyone have any data on how temperature etc affects the frequency.
