Build a 10MHz OCXO for the shack for less than $40.00

[VK2RK]

I've read that 30 days is not an unsual amount of retrace time for a ocxo that has been off for 6 months.

I noticed the effect so went looking for an answer, as to the required time depends on many factors as the linked document attests.
But the retrace explanation document is in the other thread. (http://www.sadarc.org/xenforo/uploa...o-understanding-of-device-idiosyncrasies.163/)
