The labels may or may not be significant. If the frequency is indeed -2.94 Hz at 2.5V EFC, you could probably get it back to 10 MHz by increasing the EFC voltage. You can also decrease the bridge capacitor to bring the frequency up if necessary. The factory was supposed to choose the capacitor

Hi Rick: I've heard that but it's not clear to me which oscillators are in the non aging catagory. For example what about the HP 10811 or the Stanford Research SC 10? The plot on Brooks Shrea's web page for his GPSDO shows linear aging on his Austron 1250. See:

); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] RETRY No oscillators are in the non aging category. However, the E1938 and 10811 are in the RANDOM aging category. As I previously said, the direction of the aging is random. Now you have brought up the so called disciplined
