[time-nuts] Isotemp OCXO question

[Robert DiRosario]

I got a  Trak Systems "Time Code Translator" from ebay.  It's a 1U box 
with large LEDs for DOY and H/M/S that translates IRIG-A to NASA-36 time 
code.  I plan on using the case for my WWVB clock.

Unexpectedly it has an Isotemp OCXO in it, model OCXO59-11-2, frequency 
marked as 1.000 MHz  The Isotemp website is more or less dead, it has no 
information on it.  Does anyone have any information on this model, like 
how accurate it is?  It has only three wires, which I assume are power, 
ground and output, with no EFC input.

One thing that I'm sill note sure about is what to do when the receiver 
is not receiving WWVB.  I was thinking of using something like the 
DS3231 RTC module.  If this OCXO is better, I may use it.

Thanks

Robert
