I looked at this when it was mentioned here a few weeks ago. I did the
procedure in an hour or so and it's working well, keeping the PPS within
50ns of GPS with 6-8 satellites. Monitored by the patched version of Z38XX
at the moment though I look forward to putting Lady Heather on the job.

The curious thing is, although that file is hosted on eevblog, I can't find
any link to it from the forums. You have to know where to find it.


Perhaps we could get a copy on Didier's site (with the author, Peter
Garde's permission) before it gets lost ?
