Hi Are you worried about phase noise at 100 Hz and above (Trimble OCXO) or about sort term stability at 1 to 100 seconds (MV89)? Two different things, and you don't get both at the same time on the crop of what's up for auction at the moment.
Of course you can get a broken one in either batch and there are a *lot* more MV89's out there to sort through.

Now that I think of it, it is surprising to me that OCXOs even work. About the worst thing you can do to kill the reliability of electronics is store and operate it inside a heated oven. Cracks in solder joints are the kind of thing you'd expect after many thermal cycles One question: I was thinking about buying one of these MV89As. Are they the best of the $25 OCXOs for short to medium term phase noise/stabilty. Trimble, Isotherm and others are all about the same price on eBay. How to decide which to get?
