I would definitely be interested in a circuit board. I have several older but unused 10MHz TCXO's and hope one of them could be fitted to the layout [they are 1 1/2 or 2" square] I expect I will need some type of adapter to get onto a 1.6" high board or just treat it as an external reference standard.<BR>
<BR>
Some layout space for a stand alone / adjustable voltage regulator might be nice. Many TCXO's run from regulated 12v, but I have one that runs on 10V - newer ones probably lower. Frequency standards should be run 24 - 7 to minimize the aging and drift. Can take up to 30 days to reach final stability after each power up [properties of quartz], so probably would not want to run power from the Atlas bus for the TCXO.<BR>

Thanks,<BR>
