[time-nuts] Ebay FE-5680A Rb: Are they that good?

Think you are correct for most things we do.
However in communications for mixing and such a sine wave is desirable and
a very clean output to minimize things like IMD and other products as we
get the 10 MC to its final frequency. Since you are a ham you may
appreciate that.
