Hi

The X72 may run a DDS to do it's output.

It's the output of a programable divider.

Nasty in what way ?  Noise ?

Reminds me. Friends of mine had problem with a new rubidium. They had more 
jitter than the phase-noise motivated. It prooved to be the 100 MHz pumping of 
the rubidium lamp that broke through, which was obvious when scoping the 
signal. It wasn't a X72, but it was a small rubidium.
