Attached here is a long term AD plot of an FE405B. Stays in the 10-13ths all the way up to 10,000 seconds! This unit has only been operating for about 2 weeks. In a month I'll repeat this plot and also include the aging rate. I have found that these oscillators exhibit less drift than most others I have tested! Cheers, Corby Dawson

This is interesting. Do you have an idea why your unit peforms so much better than those that TvB measured[1]?
