The delay column shows the same small delay on all 3 boxes. That pretty much
rules out something strange on the network side.
I would add a few outside clocks. That might help you figure out which clock
is right/wrong. (Both Arbiter's could be setup with the same error.)
You might check the antenna cable delays. (on all 3 boxes) Somebody might
have typed in the wrong number, ms vs ns or km vs feet.
What sort of setup is LeoNTP? Is it triggering on the trailing edge of a 10
ms wide PPS pulse?
These are my opinions. I hate spam.
