[time-nuts] OCXO retrace, how long is reasonable?

Well, I could measure the EFC voltage every other day and if it'schanging, then it's the OCXO that’s drifting, if not (or not inaccordance to the DAC graph) it's the DAC itself.

One can buy 5 digit LED meters on ebay for $5 each +shipping.

 While I wouldn't necessarily trust their accuracy, at that price one could buy 3 or 4 and continuously measure  several variables.
