[time-nuts] E1938A phase noise improvement

[Stewart Cobb]

Rick Karlquist mentioned some time ago that the phase noise of the E1938A
could have been improved by a simple change, but the production managers
were unwilling to apply that change because there was no customer demand
for it.

What was that change, and is it feasible for a skilled hobbyist to make
that change on an individual existing unit or two?

Cheers!
