All,
I have some pictures of the disassembled unitas of the state of it right now.
Where can I upload them?

I got into the package out of the dewar of my FTS 1200-100 without breaking

Hi Ed,
Thanks for the pictures. I had to change the dewar flask on one of mine,
so I saw about the same thing some 10 years ago or so, but memory.
Didn't go all the way into the oscillator.
The oscillator picture is mirrored.
Cheers,
Magnus

I looked at the photos, but can't make any sense of your comments about the
multivibrator. Was this a joke?

A couple months back, Gregory posted a heads-up that there were some
pretty cheap Novatel dual-frequency GPSses on eBay (thanks, btw!). I
managed to get one of these ('make an offer' for $450) and ... it's
actually pretty nice. Not only a decent GPS, and dual-frequency, but the
included antenna
Does anyone have a service manual or any information on the European
Electronics Systems (EES) Radio Clock Model 100. The company was part
of Siemens but closed down in 2005. The Model 100 was supplied by
Plessey Defence Systems to the UK military. Some models could be GPS

Hi
I would bet that the design changed a bit since 1983. That is a “long time ago”
in terms of OCXO design. Since we are picking up this stuff surplus or pulling
it out of older gear, who knows what era this or that example might come from.

You found the secret. There is no RF wiring to the crystal. The oscillator
frequency is determined elsewhere, with a free running multivibrator that is
approximately on the right frequency. All this talk about precision is
baloney; the circuit is stable enough to fool even the experts.
And i
As much as the pictures are interesting the sites blasting out crazy
amounts of ads
Totally a problem. Touch anyone of them and off you go to whatever it was.

It sounds like yours is different from my 8601. How old is yours? From
the label inside it looks like mine is from 1983.
Internal pictures are here:

Consider taking pictures of the process. That would be a great document for
users that need help.
Someone will post them on there web page. I have done this for things I
have built and shared.
Then we can see what you are running into.
As you have seen you have a huge range of expertise.

Hi
One of the basic issues with a quartz resonator is that it is sensitive to
barometric pressure.
Some are more sensitive than others, but there always is some effect. Various
techniques
get used to isolate the resonator. Solder sealing (or welding) the package
closed is one of
them. The in
Can you get an x-ray of the core?
