[time-nuts] W. Riley's Small DMTD System

Hello,

I'm currently working on the small DMTD system.
The mixer modules and DDS are working, but the noise floor is still more 
than an order of magnitude higher than published in W. Riley's paper.
Also, I'm having troubles to get the PICTIC's working. For the time 
being, I'm running the mixer and DDS together with a HP 53131A in TI 
mode with TimeLab.

There are a couple of questions that are probably easy to answer by 
someone who has built that system.
Any hints would be much appreciated.

Adrian
