[time-nuts] Strange effect with C-Field change

Well, if you figure out how to introduce a 100 mS delay with a
short length of cable, you should see a patent attorney.

Wait a minute. Aren't you using a homebrew divider to get 1 PPS
from the 5061? That's a fine way to get long lasting offsets, but
I can't imagine why it curved up or why the offset went away. My
money's on the cordless phone or static electricity.

All --

Thanks for all the comments.  It must be a slow afternoon/evening!!!

You've given me several things to check out.  In addition, as I was 
looking at the hardware in the basement I now have a suspicion that it 
might be a cable problem, specifically in the cable that goes from the 
5061A PPS output to the TIC input; that cable might have moved when Jody 
opened the control panel door on the standard and if it was marginally 
faulty, it could create a transient.  A transient lasting several hours 
is a bit odd, but who knows...

I want to keep things in stable state for another day or two to get my 
offset value at this C-field setting, and then I'm going to test both 
the cable, and the other hypotheses you all have suggested.
