Thank you.  In particular, WWV, as compared to WWVB.

What you're looking at (unless you're very close to WWV or WWVH) is the uncertainty in the skywave path through the ionosphere.



Is there an on-web reference that I can document, so that the NTPSec

A reference to what WWV radiates as a signal?
