Hi At least from here, that link appears to be broken. If it's the same details as on the NIST web site, they are already part of a thread here.

I'm sure most of this group has seen the information put out by NIST regarding the changes to the WWVB format. But, for those who may not yet have seen this, here's a link to it: http://f1.grp.yahoofs.com/v1/cBhjUH41xVccWM9P8EU4JqzmFNevFgDUFkRcgfLyry1Rn3H qMV5iDqYDgsd2pM1-Vq3nhF9WERTjVF_WmRjAezjU9CCrAda_8RqV/NIST-Enhanced-WWVB-Bro adcast-Format.pdf The results of this change will apparently no longer allow WWVB to be used as a high accuracy frequency standard signal. This does not seem to be much of an issue considering the availability of the GPS signals all over the world. I use GPS as my frequency reference for my "Off-Air" broadcast frequency measurement service. Some broadcast stations also use GPS as a reference for their transmitters. I'm sometimes asked why I use GPS as a reference when it is not recognized by NIST as the U.S. Frequency Standard? Other than explaining the capabilities of GPS as a reference, I don't have a real answer for their specific question. I have publications from NIST showing the accuracies obtainable using GPS, but it still does not appear to be an "Official" U.S. Frequency Standard. So, I guess my question is, when will NIST officially recognize GPS as, at least an alternate, U.S. Frequency Standard? Have I missed something? Thanks, Burt, K6OQK Burt I.
