The short-term performance is 10x worse if you don't shield the TCXO from air, even if the ambient air is "still". I suggested Said sell the product with some sort of engineered shield in place. Instead each of us will solve the problem in our own way; which is ok for a dev kit.

For plots and photos showing performance with, and without, and with insulation see:
The difference is dramatic, especially if you are used to working with OCXO where this sort of effect does not occur.

The insulation may be found in convenient rolls at many local stores. I used TP, which for this application is an acronym for Thermal Paper.
