Some the guys around here use them on 10 GHz SSB.
You really need that kind of stability for that mode.
A TCXO is 100X worse. Another popular use is as
a "flywheel" with GPS, to get a very accurate frequency
source. Search on "HP Z3801" for info.

(I worked at the HP division that made these for 19 years.)

What possible use does a HP 10811-6011 Crystal Oscillator have in a
homebrew project. I came across one of these but don'y really know
what to do with it. I hate to toss it out.
