Atomic clocks

Here in Texas I always use my atomic clock that I have here at home. If I take it with me to our home in the Lake Chapala area will it function? Does the signal reach all the way down there?

It's iffy at best for several reasons, it comes from Colorado which is a loooong ways from here, we're sitting up against mountains to our north, and, due to the construction of our casas, primarily brick, concrete and steel, the signal has a hard time. I have three on the weather station(s) and in 4.5 years only once did one of them lock on. One of my greatest battles with the wireless stations is getting them to receive consistently, I never had an issue with the same equipment in Texas. It might, or might not work, you'll only know when you're here, not much help I know, but it is what it is.

My basic Oregon Scientific weather station has a radio controlled clock (Atomic Clock is generally a misnomer) that receives its signal from the NIST radio station near Fort Collins, CO. Placement in our home does affect its reception. It works best when placed near a window facing north. Keep in mind that Mexico changes from standard (winter) to daylight savings (summer) time on different days than the USA which will affect synchronization.

For more on radio controlled clocks check out this link to the National Institute of Standards and Technology website.

That was the one time my OS locked on, it was sitting temporarily near a second story N window, unfortunately to connect it to the PC it has to sit with two brick walls between it and N, so it's out of the question.

Thanks for the info. Sad to say there is a two-story building north of my house.

"...NIST radio station near Fort Collins, CO"...

My radio controlled clock at home works just fine. Of course I can look out my windows and actually SEE the towers just north of my house. Ironically most of the population of Fort Collins is oblivious as to the function of those towers!

Is there really a big demand for this accurate of clock in Mexico? Nothing here occurs on time.

Hey Rick,
It's quite an array.

I can see their lights from the deck on my west Ft Collins home when the leaves are off the trees.
Do you fish the reservoir just east of the towers? Nice trout.

Our clocks here in Merida get the signal, if pointed north from a second story room.
Enjoy,
steve

Good point, I wear my wristwatch once a year when I go home, there's always a guy at the LCS entrance trying to sell watches, I just laugh and shrug my shoulders.

My most accurate clocks are via satellite (Shaw Direct) and via my Telcel phone. They're not as accurate as an atomic clock, but they're accurate enough for this old ruco.

Is this clock one of those that you plug in & then set the time zone that you are in with buttons on the back and it will then set itself to the correct time? If so, we have one and it works just fine here in Comala, Colima and its in front of our flat screen TV, near a window but no towers in sight. Maybe it is by satellite of some sort?

The signal in our hemisphere is a high power low frequency 60 kHz RF broadcast.

My husband insists that our clock is about 3 min. slow, compared to times shown on the guide on the TV and the computer time shown on the display. Could this be correct? Should they all be the same?

If your clock(s) is off from this (note the posted network delay), then your clock is not sync-ing with the NIST signal.

I have a Casio solar powered atomic watch and the signal from Ft Collins does indeed get to Ajijic. I know this because of the difference in Daylight Savings Time start/end dates. On the day the US changes time, the watch flips forward in March and backward in October. I have to change the city source to Denver during the 4 weeks when Mexico doesn't conform to US standards.
