Hello Keith,

I am sorry to tell you, I did not yet receive the module,
don't know what all hells customs is doing with it!

My idea is to add a good OCXO like a hp10811, similar to be used
as my good old trimble thunderbolt using the laptop.
Perhaps I will need then some support for.

Many thanks, regards

Arnold, DK2WT
