The main reason for manually doing the self-survey and saving the results is so
that the unit won't spend hours doing it every time it powers up. It's a one

Every foot of position error can introduce a nanosecond of offset in the timing

Yes, you can just leave the unit running without much problem, but what works
really well is to use an old laptop as a permanent monitoring device. You can
get them for around 20 bucks... Lady Heather was created for Thunderbolt just

Yes, it's helpful on the way to perfection. Is it a requirement for the
OPs level of ambition? I think not.
I wonder if the long self-survey procedure is an artif

For really good adapters, I've had good luck with S.M. Electronics
(http://www.smelectronicsllc.com). They are pricey -- like $24-$36 each

I've purchased several items from fluke.l (that's an L not a one) on eBay
with good results every time. The only "problem" I ever had was just this

Many thanks Mark.
I was thinking of setting up in a fixed position and leaving on
permanently. But then if there's a power cut?
Do you know if the China supplier is OK? Or any source in the UK of
Thunderbolt?

There is one thing that make most GPSDOs not quite plug and play... that is
their need to know their location rather precisely. They do this with a "self
survey" mechanism. The self survey can take several hours. Most units can
trigger this automatically if their location changes more than
