[time-nuts] OCXO Adjustment Question

[Frederick Bray]

Thanks for all the helpful suggestions and comments so far.  I will 
answer a few of the questions that have been raised.

The device definitely is an OCXO as it is in an oven and gets warm. It 
is an Ovenaire 73-25.

As one person commented, there are two 10 MHz outputs on the device.  
Actually, it appears that the Ovenaire has one output and there is a 
resistor network external to the device that splits the signal.

So far, the range seems to be from around 9.999975 to 10.000025 and it 
has been on for over 18 hours.

I am going to let it sit for a bit and then try the various tool options 
that have been suggested.

One suggestion was to replace the Ovenaire with something like a Morion 
MV89.  That would seem to be a good long-term option.

All of this started as an attempt to track down an "unlock" problem with 
the 5110 to see whether there was any output from the Ovenaire.  When it 
turned out that the OCXO was working, I gave into the temptation to 
tweak the frequency.
