It does look as though KL7UW’s page has been hijacked.

Everything you need to know for setting up a surplus OCXO:
http://www.kl7uw.com/10MHzREF.jpg
one caveat the power cube was a mistake as it output a 0.5v
triangular wave at 120-Hz riding on the 12vdc output -not good. So
use a well filtered-regulated 12v PS instead (battery optional).

Have a look at this, Sverre, it will tell you all you want to know.

A question regarding the DOCXO, double ovenized crystal oscillator to Chuck,
W7CS. I'm completely new to this, but after having looked at a few in ebay,
I see that they have an input for frequency control.
Do you use them as is, or do you calibrate them by setting the control
voltage? And how muc
GPS stabilized 10 MHz crystal oscillators are really an overkill, to
be references for todays transceivers.
A good DOCXO, double ovenized crystal oscillator, is more than
adequate, some even claiming accuracies of 10 parts to the -11th
. I have purchased several, through Internet advertisers
How do you know that?

They are still available on eBay: search "Nortel Trimble” and the first item
that comes up is a complete unit with GPS antenna. I bought one and it works
perfectly and produces a 10 Mhz output for the K3EXREF board. Needs a 24 VDC

A couple of ham designs, which you can buy, not cheap, but good quality.

Count me in!
Ever since i got that REF board - i've been looking for that elusive Trimble
unit.
People had told me that eBay is full of them for like $70.
Yeah, right! Maybe 10 years ago...
Now, they're about $200-300 depending on power supply availability, and you
can't even find them...
So, yea

The Trimble Thunderbolt is scarce on the used market and when they appear the
price is painful. They were designed and manufactured for the BB wireless and
cellular market when the industry switched from analog to digital synchronized
cell sites. I was part of that out business.
