I bought one just for the heck of it for $40 plus shipping. It was advertised as new, (he has changed his listing) but it was not factory new, had been installed at one time but no sign of usage. It had also not been "tuned"since leaving the factory and it was within 5 E-11 after a day. After controlling temperature and looking at 1 E-12 for 10 days I have not detected any aging. Tuning is done through the RS232 input in 7E-13 steps. I plan to modify mine and use C field control. I like what I see, well engineered. Bert Kehren. In a message dated 12/8/2011 2:55:05 P.M.

But is is still not clear to me if these are even adjustable and if not, how far have they drifted off of 10Mhz since they were new. I'd like to buy one and calibrate it to a GPS.
