Moin,
I'm quoting the mail in full, because it seems to have not made it to
the mailinglist due to its large attachment.
I uploaded the attachment to my server, you can find it here:

That's something that has been bothering me lately: Most of your
publications are about the noise in UHF and GHz applications, hardly
any for the area where most of time metrology happens: at 10MHz and 100MHz.
Is this because the sub-100MHz range oscillators are a solved problem
and hit the physical limits of what noise optimization can do? Or is
it because there is more money to be made in the >100MHz range?
