Joerg,
It all looks good to me. I didn't notice any problems at all with the
English text. Much easier to follow with the improved pictures.
I notice that the annotations on the picture for the German version are
the same as the English version now. Very little that would change
("move" and "pad"?) and probably easy to figure out, so probably fine as
it is. Just thought I would mention it.
Thanks for sharing your Mods. Nicely done. Should be helpful.

Rex,
I made some modifications to my article and I hope, that everything is
ok now. Please feel free to correct the text if you find some spelling
mistakes (very likely) because my english is not perfect, hi.
Thanks for your help,

Joerg,
This looks like a very useful mod on a unit that many of us have. I'm
not aware of any schematics available for these, so I guess you have
reverse-engineered the "black" part of the schematic that you
provided. -- Nice work!
Having said that, may I offer some minor criticism (constructive and
positive, I hope) of your document?
The schematic you provided shows the key transistors as Q1 and Q2. In
the text you refer to Q208 and Q209 (which I think are marked on the
board). From the description, I think Q1 = Q208 and Q2 = Q209. It
would be nice if the schematic had the Q-numbers changed, or at least,
you mentioned the equivalence in your text.
(Trivial) Aren't you using an existing SMA connector for your output?
So, maybe it should be black in the schematic.
Your picture of the board rework is pretty low resolution; even
zooming into it just gives bigger blurry image. You have added some
annotations but they are in red over the green board color. Combined
with the low resolution they are very hard to read. I'm pretty sure
they remain in German in the English version too.
My suggestions:
- Edit the schematic to change the Q-numbers to match the board
and text, or at least give the equivalence in the text.
- Use a higher resolution picture and make the annotations more
readable with different color or background shading.
- The picture you provide is "after". It would be nice to also
have "before". If you don't have a before picture, I or some other
member could probably take one.
- Consider having picture annotations in English for the English
version.
I think what you have done is great. I just think the sharing document
could be improved to make it easier for others to duplicate.
If you like, I could possibly help make a more readable annotated
picture if you can provide me a higher res picture of the board. Just
an offer to help if you would consider my suggestions. I think you
will see my email in my post.

Hi,
I worked out a modification of the Lucent GPSDO to get 10MHz out of it
which I offer to the community. The article is available in english and
german (attached).
