That's a shame. CHU is usually the first thing I look for when I turn on my shortwave radios (which I guess isn't all that often). Usually comes in a lot better than WWV in my area.

Indeed, even if I don't do anything else with my HF rig, usually I'll check good old CHU. Can't always make out the verbal parts, but those tones usually cut through. Been setting my clocks by CHU for literally decades. Going to miss that.

From what I can tell, it looks like they posted the entire spec. What's to stop someone from reproducing the signal on an alternate frequency? As far as I know, you can't rebroadcast the original, but if the original is gone, then it's not really rebroadcasting...

This is a project I have seen a number of times, where people make a low power transmitter to set their WWVB wall clocks and watches which don't get a reliable signal.

And here I was thinking how it would be fun to make a decoder for those 9 warbleys in the middle.

Makes me wonder if WWV will meet the same fate.
