Ha ha! Wonderful. Just by chance, happened to catch it as the top the hour rolled over, so got to hear the full station ID. Great fun. But what do you do about propagation and weather announcements? :)
My favorite WWV story: Was helping set up a ham radio station with a rather low-end transceiver (I did not select it...) anyway, there was this one multi-band antenna we were tuning up, and every time we got it close to matched, the receiver went nuts -- crap all over. I needed a signal that I knew would be reliable and where I knew what I would be hearing, so I tuned in 10MHz WWV. When the antenna got close to a good match, I started hearing Mexican polkas.
I quickly dismissed the possibility that WWV had changed its programming.....
As it turns out, our station was about 4 miles away from a local AM station and we were right in a major lobe of their pattern. The crappy front end on our receiver got totally crushed by overload from the AM station, which of course caused IMD products in the first mixer from "DC to daylight", as they say.
Solution: Quickly knocked out a high-pass filter that we could transmit through at 100W. The Polka-Be-Gone(TM).
If you did not follow the links in the article, WWWV is at risk of getting shut down due to budget cuts . There was a petition drive to keep the stations operating  but it failed to get enough signatures.
I have an SDR in my office hooked up to an outdoor random wire antenna. So far this morning I've listened to shortwave broadcasts from France, Nigeria, and Saudi Arabia. The HF band is even more fun at night when propagation is better.
There should also be doubled ticks near the start of the minute to indicate the difference between UTC and UT1 (i.e., how close we are to needing a leap second). There is one right now, but I did not carefully count what second it should be attached to. (Going to guess 9 though.)
Yep! I tuned in CHU regularly. I originally intended to include it in the app as well but: getting audio was difficult since the telephone time isn’t the same as the broadcast, there is some ugly legalese about recording it IIRC, just the WWV portions were dragging out and I wanted to be done!
This makes me so happy. I started out as a short wave listener (SWL) before becoming a ham. WWV was part of both hobbies though it's been quite a while since I've heard those tones and it took me right back to my childhood. WWV should be part of the web, thanks for bringing it there.
