[time-nuts] new WWVB BPSK dev board

[David G. McGaw]

That is the specified jitter.  They have also said in communications that it has about 50mS resolution.  That is as close as they are willing to say a system can be synchronized with it.  Perhaps someone will discover a clever way to enhance that.

BTW, I have been told it has also been successfully tested for lock in Brazil.  Is there anyone in Australia want to give it a try?  Perth is almost directly opposite Fort Collins.  :-)

As was said, IRQ delay is +/-100 mS from the second edge, hardly what a

There is no problem with a delay as long as it is constant.  If I know what it
is, then I can correct for it.

The problem is the noise/jitter on the delay.  I'm sure somebody will have
data soon.
