For the low noise  nuts, here are some modern techniques . 
At the moment I  am looking at 1/f noise , or better how to keep it low. 
I am supervision  an dissertation on this topic and I am happy to get some 
input.

What a  pleasant surprise to see Ulrich post on Time-nuts. We spoke many
years ago  on radio on as I recall an opening on 2 meters FM.
I have to agree with  Azelio for many of us it is the other way around. We
would learn as we do  from many of the other excellent Time-nuts mentors.
Best regards  Ulrich
