Hi

You have a *ton* of digital this and that all on a common ground with the RF output. 
The original specs didn’t sweat the spurs so the designs are what they are. The OCXO’s 
are down in the -130 dbc/Hz range at 10 Hz offset. The Rb’s ten’s of db worse. Nobody
seemed to mind ….

If you go back about 10 years in the archives, you can find a lot of the data on these parts.
