[time-nuts] WWVB Signal Generator

[paul swed]

Great to see the threads. Take a look at the Chronverter.

Its done all of this. I don't get anything by promoting Daves design. But
am having very good success with it on my Spectracom and Truetime clocks.
I would like to look at the code because I can already see some changes I
would like to do.
But all in all its very clever.
