Yes, that’s true. Given the facilities I have available with the present hardware, I don’t believe I have much choice. I am not confident that I could tell the difference between noise in the phase detection system and PPS jitter variations that small. If the PA6H receiver gave sawtooth corrections, I’d be able to do better.

So now that I’ve said that out loud, I’ve gone back and taken a thousand points from log and plotted them in excel. Looks a *lot* more like sawtooth than noise. Hmm. I might have to reconsider. > On Jul 18, 2016, at 8:06 PM, Nick Sayer via time-nuts <time-nuts@febo.com> wrote: > > >> On Jul 18, 2016, at 3:55 PM, Hal Murray <hmurray@megapathdsl.net> wrote: >> >>> The systems gravitate towards PLL time constants that average it all away. >> >> You are overlooking hanging bridges. > > Yes, that’s true.
