John & Skip,
as I am getting 5 such oscillators, I will open 2 or three (after
measurements of the PN ) and apply some magic...
To build something like this mechanically will be tough. The technology and
circuit design will have changed a lot in 10 + years, so I will try.
Opening the units may be the tough part.

I have a few of the 500-6769 parts here, and measured a couple of them
Not a bad price at all. If a $2000 OCXO can achieve -140 dBc/Hz at 100 Hz
and a $50 OCXO will do -117, that's almost 10 dB better than the expected
20*log10($2000 / $50) ratio. :)

The units have been paid for and are being sent Priority Mail. Pleasure
doing business with you.
If you have any feedback on what the phase noise does look like I would
certainly be interested in the data.

Please excuse the blatantly commercial announcement, I generally keep
business matters off the list, but I have some Wenzel oscillators that may
be of interest to time-nuts and wanted to give you first crack at them.
These are Wenzel 500-06769 units, custom number for Harris used in
microwave radios. Output is 100MHz at +20dBm. Supply input is +12 volts
DC (about 500mA at start). EFC runs between 0.5V and 4.5V with positive
coefficient and is about 335Hz/V.
Unit is in standard 2" x 2" x .75" package. Output connector is female
These would make great units for synthesizer and DDS projects. I don't
have the ability to measure the phase noise, but should be relatively good
as they were used at microwave frequencies in their past life.
I'm asking $50 each for them and $7 (any quantity) Priority Mail shipping
to U.S. addresses only. If you would like one (or more) please PayPal to
_paypal at rdrelectronics.com_ (mailto:paypal at rdrelectronics.com) . I have
attached a picture of one unit with the
RDR Electronics, Inc.
