Hi Gary,

> As requested, here is my raw data: http://pi5.rellim.com/1d.log.gz

I'm having a close look. These are quite a few bad data points and that partly explains why your ADEV plots were off. Trim the file at, say, line 71000 and try again; the results will be much better.

I'll post an in-depth report later. There are interesting things in the data. You're going to have lots of fun with your new TICC and GPS boards...

> I'd love to use TimeLab, or Stable32.  But they seem to be closed source,

Nope, not closed source.

John Miles includes all the source in the TimeLab installation.
Ask him for a zip of the installation if you can't/won't run the setup exe.

Bill Riley very recently donated his Stable32 source tree to IEEE and so that tool joins the club too.
Not sure where the source repo is but someone on the list will know, or know when it will be ready. Long thread here:

Someone who routinely uses these apps on non-Windows or non-x86 machines can comment on how to do it.
