in a mixer and using the 10 MHz sum output which (apart from noise added

Has anyone here done any performance measurements of the Lucent RFTG-XO

and wonder if anyone else has looked closely at these things.

This is getting off topic (because it's far to practical!) but hanging
heaters on crystals is a time-honored activity for hams. Many of the
surplus FM rigs for VHF and UHF that we obtained from the likes of
Motorola, GE, RCA, e

The Midwest VHF/UHF Society (located in Southwest Ohio) is pleased to
announce that the first annual MVUS Frequency Measuring Test will be
held on Saturday, October 13, 2007. There will be two transmission
periods: the first at 14:30 EDT (1830 UT
I was looking at the wrong plot when I mentioned the noise floor of my
5370B in frequency counter mode; blame my temporary mono-vision after
having had some eye surgery!
If you look at http://www.febo.com/time-freq/hardware/5370B/index.html
*properly*, you'll see that the actual noise floor is abo
