The WWVB broadcast system is being upgraded, and may have outages.

[www.nist.gov] Even on the Windom, late nights, after midnight, I'll tune down to 60kHz and check WWVB's signal strength. On good night, I get it at S+30/9. Then, there are nights where it's just barely above the S7 - S9 noise levels. That Atomic Clock, a fairly cheap Chinese ceiling project clock that I have, switched to DST before midnight this time for the Spring Ahead +1hr. (Interesting.) Hey, I actually don't mind my tax $$$$ paying for this. Better than what our tax $$$$ usually goes for, but I'll digress, this time.
