omg this has bugged me since then but at 2;05 after the tone what is that double tick sound? I would still get it if I called the phone number to the station

[PresentedIn4D]

Do I hear BPM morse in the background?

[mrksvideos]

@PresentedIn4D Ya know, I think I do hear it as well when Jane (WWVH) is done speaking. I might have blamed it on the compression of the video, but after hearing the BPM broadcast I now know what it sounds like (Thank you YouTube!). You are probably right, being from the west coast of the US and being able to ALWAYS hear Firedrake, it is most likely that BPM made it in there. Good catch!

Thanks for presentation this Time Signals. 73

[philglassfan]

WWV's announcer is perfect!

[PresentedIn4D]

@philglassfan For the time, i'd say WWVH's is nicer.

[ChemistInJapan]

@PresentedIn4D Both Jane and John are awesome people, but I'd have to agree that I like listening to WWVH. I love it best when I can hear both at the same time.

[PresentedIn4D]

@ChemistInJapan I never get Jane up here, I've heard her once. However, when I go south, I hear her clean and clear.

what's the bass tick for? i know the higher one ticks the seconds.

[mrksvideos]

The bass thump is the 100Hz subtone tone that is a Binary Coded Decimal that is used so receivers that can decode it can decode the current minute, hour, and day of year. Stupid YouTube will not allow me to post the NIST direct link for some reason. So this will have to do. Replace the asteriks with dots and -FS- with a foreward slash.

@MaryStewart Atomic Clocks (Clocks that set themselves) decode those bass ticks. It includes date and time information, including that particular hour/minute/second.

[Cotronixco]

@bigsky1970 Those are not atomic clocks. They receive RF information from an atomic clock site on a very low frequency.

[SubaruB4RSK]

@bigsky1970

Yeah I found a site long time ago what tuned into what the atomic clocks hear and it was that same bass sound.. Having said that I don't live on the west coast so it's pretty cool to hear both WWH & WWVH at the same time I can just hardly make out the WWH signal from here.

[drbitboy]

Thank you for doing this.

[thenewageriseth]

Pretty cool; you had taped this on last years' New Years' Eve. XD

[dwarfer777]

what a crock, only a tosser would spend this much time and effort on this bullshit

[thenewageriseth]

Coming from a HATER.

Haters hate.

[mrksvideos]

LOL! Oh the llittle brains out there...how they wish they could understand the beauty of it all.

[uploadJ]

GREAT bass response on this recording!

[mrksvideos]

Well I will admit, I tweaked with the bass a little, I put it in my sound editor and amped the 100Hz response a little to make sure it was evident to the listener without having the listener turn up the bass to hear it. The 61 second (leap second) has a slightly different timing than I was used to.

[uploadJ]

Even better! You are a master at this!

[denelson83]

There is no "international time bureau", BTW. It is called the "International Earth Rotation and Reference Systems Service".

[uploadJ]

That's interesting; if I do a Google search on these 3 terms: international time bureau, I come up with reference along these lines:

"The Bureau International de l'Heure (BIH) or the International Time Bureau, seated at the Paris Observatory, was the international bureau responsible for combining different measurements of Universal Time."

YMMV

Did it happen at video time 2:01?

[mrksvideos]

Yes it did. If you count the second pulses and count when you don't hear anything (or time it with a stopwatch), that minute has 61 seconds.
