[time-nuts] Realistic Tbolt phase noise

Hi,

I noticed several vendors on Ebay have the t-bolt on sale.

However, the once showing their own PN plots seem to get only
-115, -120 dBc/Hz at 100Hz. Yet,
http://www.leapsecond.com/pages/tbolt/noise.htm seems
to have mucht better results: up to -150 depending on
power supply.

By multiplying to 1GHz I also seem to be getting something
like -75 or - 80 rather than -110.

Any thoughts?
