Jason, we just did one using the ublox at 1 KHz and I have some boards  
extra so if you contact me off list I will gladly send you some data and  
schematic .Can be modified for 10 KHz.

I should  drop an email rather than just lurking on this extremely
interesting  list.

I'm in the process of building my first GPSDO, so I have lots to  learn
and am enjoying the education.   This list has been a real  eye opener
for me.

I'm a licensed amateur radio operator looking to  move up into the
microwave bands, and I spend a lot of time repairing old  radio kit for
reuse by other operators.   As such an accurate  time reference is
important, hence this project.

So far I've based  everything on a number of published sites and
designs to learn the basics  before launching into something more
adventurous and am building a simple  PLL locked OCXO using a Navman
Jupiter Tu60 GPS and an IsoTemp  OCXO.   Together these will exceed the
limitations of my  equipment in measurement, so I'll probably have to
build a second one for  comparison on the DSO or look into other
measurement methods to validate  the results.

Lots to learn...


Teach  your kids Science, or somebody else will  :/
