Thanks for the very helpful explanation about the DAC voltage.
I think I'm going to proceed with my separate bi-polar rail supply
just because I have it working that way now.  But I understand
now that the problem is perterbances of the PWM.  That makes sense.

I have not given much thought to the statistics needed to monitor
this thing.  The time-nuts guys talk about Tau and other mysterious
stats.  I really don't know what that means.  I've been in
the state of just marveling that it all works.

My MonTrol stats window usually shows 1.xxE-9 in the long range
frequency deviation.  Would that be .02 Hertz?  Pretty cool.

Yes, thanks Bert for the work on this board and software.
And thanks for the support, getting it up and running.
