Fred, Be careful about the 'tweaking'. It can become very addicting. Short of a GPSDO, you'll always have to tweak from time to time. The problem is being able to define what tolerance you are willing to accept and how often you don't mind tweaking.
Otherwise, you never get any work done, just spend your time 'tweaking'.

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.
