[time-nuts] Re: Is this good?

[paul swed]

Andy I think it does indicate its good and locked. Also amazing. The fact
that it was in standby really was good.
Oh to have a beam current of 30 on one of mine.
However this being time-nuts good is always a bit of a question. How good?
As a Ham most of what I do would call it totally good.
You run the way I do 3-4 times a year check and compare....
But I suspect that the noise may be higher in the system so maybe graphed
against something else it could appear noisy and jittery.
Still sounds like a keeper to me.
Others will have better comments.
Good luck.
