It would be more precise to say that no amateur has been willing to
talk about their results yet.
I personally know several have tried and failed at various levels
My own personal experience, both analog and VHDL, is that there is
a particularly long and noisy way from theory to practice in this
The one thing I have *not* tried, and the only one I think has any
realistic chances, is to use a DDS chip which has a phase modulation
That should get you to a nanosecond without too much trouble.

Never attribute to malice what can adequately be explained by incompetence.
