This morning my radio controlled clock was 8 minutes fast, something which has never happened to me before.

Didn't realise it was wrong until I switched my phone on and saw that it agreed with my oven clock instead of the radio controlled clock.

At first I thought the oven had suffered a power issue and lost 8 minutes! It's back to normal now. Has it happened to anyone else today? Better than it being late I suppose. KnobTwiddler Posts: 1, Forum Member.

I've noticed that the MSF signal has been off the air at times recently, it's normally off at times for maintenance during June. What side of the house is it compared to the Anthorn transmitter where it gets its timing signal from?

That explains why then. Zenith Posts: 3, Forum Member. It's unusual to suddenly be 8 minutes out. Radio controlled clocks only check their accuracy every few hours, or some, like my analogue clock, only update once per day.

In between they use the accuracy of the quartz crystal to keep time, so even if you lose signal for a long period of time, the clock should still be as accurate as any other quartz clock. Eitshal Posts: 2, Forum Member.

It will have been the engineering work referred to above. Mine sorted itself out last week after 6pm when the transmissions from Skelton resumed overnight. Ex Pat Posts: 6, Forum Member. Anytime I've had issues with my DSF clock, it's always due to weak batteries. AngusMast Posts: 4, Forum Member. There must have been a reception error on bit 24 and on the parity bit for the minutes, so it didn't know there was an error. Phil Dodd Posts: 3, Forum Member.

Remember too that the time displayed by radio controlled clocks can be corrupted if a signal on the same frequency interferes with it, such as from an induction hob which happened to mea switch-mode power supply, and various modern types of light-bulbs.We have a couple of these and one went crazy. Just refuse to sync to time unless it was horizontal and just kept spinning. This one used to take some time to sync from new.

The part that does all of the work is a small square block on the back of the clock.

Help with WWVB Radio Controlled Clocks

Easy to remove and replace. Turns out that the hand fittings go by the name of push fit and there are plenty about. As it didn't sync well with the signal from Germany I bought one that uses the UK signal. It sync'd pretty quickly. Only problem is that it's a bit deeper than the type that was in and the stub for the hour hand is a little on the short size and needed pressing on dead square to hold.

I might have to thin the retaining nut down a touch but all's ok so far. Why bother? There are some pretty disgusting designs about. The only neat clocks I could find showed European time. We bought one for work years ago, and it showed ET. I just took the front off and moved the hour hand.

Hmmm, guess I'm not the only one then. The issue I have is that it automatically sets itself to a time zone which is 6 hours away, and even if I set it manually, within 24 hours it will reset itself to the other time zone. Can't understand why its not picking up what should be a stronger local signal? That's easily explained, though the answer won't help much. All time signals are sent in UTC effectively British winter timeand this is adjusted for time-zone and daylight saving by the local clock.

For some reason your clock doesn't believe it's in the UK. I'm surprised that someone's selling clocks that can't change time-zone.

I wonder if there's a non-obvious way of doing it hidden away in the instructions somewhere? I have an Auriol radio controlled weather station and it shows the time wrong and it also shows the wrong symbols on the weather screen, cant see anything in the instructions but they are in Chinese speak!

On the subject of radio controlled analogue clock movements, I bought some UK locked modules from Ebay and did not have much success with them. Cousins offer various forms, - with and without pendulum, with two different shaft standards, each with two different arbor lengths.

They also offer hands to fit both. They also do high torque version for large clock formats. As received from the supplier they have a locking pin pushed into the back of the case.We use cookies to ensure that we give you the best experience on our website View privacy policy. The MSF radio signal is a dedicated standard-frequency and time broadcast that provides an accurate and reliable source of UK civil time.

It is available 24 hours a day across the whole of the UK and beyond. The signal operates on a frequency of 60 kHz and carries a time and date code that can be received and decoded by a wide range of readily-available radio-controlled clocks. The signal covers the whole of the UK, and can also be received throughout most of northern and western Europe.

It is monitored against the national time scale UTC NPL and corrected when necessary, ensuring that the transmitted time is always correct.

Find out more detailed technical information about the MSF time code, signal strength and carrier frequency accuracy. MSF signal technical data. The signal is occasionally taken off-air to allow maintenance work on the masts and antennas at Anthorn Radio Station to be carried out in safety. The main causes of reception problems are local interference from electrical equipment and a reduced local signal due to screening by nearby metalwork, for example in a steel-framed building.

If your radio-controlled clock is having difficulty receiving the MSF signal, please first read through the information in the 'Common clock problems' document. Common MSF signal reception problems. The duration of each outage period will be kept to a minimum, and the signal may be back on-air prior to the times given above. In addition to these dates, the signal is likely to be taken off-air for a two-week period during summer each year, though the transmission will be restored overnight whenever possible.

The dates of this longer outage will be announced on this page and by emailed notices to registered users as soon as they are known.

These atomic clocks regulates the WWVB radio transmitter where the exact time signal is continuously broadcast throughout the United States at 60 kHz to take advantage of stable long wave radio paths found in that frequency range.

Atomic, Radio Controlled clocks will receive the signal usually at night and make corrections to automatically keep the clock correct. They will adjust for daylight saving time. Atomic clocks are sometimes called "Radio Controlled Clocks".

These clocks receive a radio signal from the most accurate clock in the world, the cesium atomic clock, transmitted from the National Institute of Standards in Fort Collins, CO.

By now, you have probably seen or own a radio controlled clock. These clocks are sold in all forms: as wall clocks, desk clocks, travel alarms, and wristwatches.

They have a tremendous advantage over conventional clocks, they are always right! When working properly, radio controlled clocks always display the correct time, down to the exact second.

This means that you should never have to adjust them. During the transition from standard time to daylight saving time DST they "spring forward" one hour, and when DST is finished they "fall back" one hour. Due to technology advances and the economies of scale, radio controlled clocks are now very inexpensive, often costing just a few dollars more than conventional clocks.

This page provides information about radio controlled clocks, including how they workwhere they workand what to do when they don't work. Some manufacturers refer to their radio controlled clocks as "atomic clocks", which isn't really true.

An atomic clock has an atomic oscillator inside such as a cesium or rubidium oscillator. A radio controlled clock has a radio inside, which receives a signal that comes from a place where an atomic clock is located.

WWVB broadcasts on a frequency of 60 kHz. Your radio controlled clock actually has a miniature radio receiver inside, which is permanently tuned to receive the 60 kHz signal. The 60 kHz signal is located in a part of the radio spectrum called LF, which stands for low frequency.

This is an appropriate name, because the FM radio and TV broadcasts that we are accustomed to listening to use frequencies thousands of times higher. The lowest frequency received by any of the other radios in your house is probably kHz, the bottom of the AM broadcast band. Even that frequency is nearly 10 times higher than the WWVB signal. At 60 kHz, there isn't enough room on the signal bandwidth to carry a voice or any type of audio information. Instead, all that is sent is a code, which consists of a series of binary digits, or bits, which have only two possible values 0 or 1.

These bits are generated at WWVB by raising and lowering the power of the signal.Explanation for scary spinning clock hands?

My boyfriend had an analog clock hanging on his apartment's living room wall which had contained dead batteries for months. One evening we were standing in front it, talking, and suddenly the minute hand started turning very fast, with the hour hand following suit.

At some point we started scrambling for his cell phone in order to video tape it. But it stopped before we could find it, right at I don't remember exactly what time it had started, but it was after midnight. Probably around 2 am. So it went from around 2 to 12, very fast. Both hands moving.

I don't intend to be vague or waste anyones time, but I would really like to know if this is rationally possible.

And obviously I don't know much about clocks. My only reference point for this sort of thing would honestly be horror movies. If there had been a surge in the battery power i'm sorry if that sounds ignorantcould that have really affected the gears in such a way as to make them spin so fast?

Or some sort of spring releasing? We didn't inspect the clock before throwing it out that night literally so I probably can't answer questions about the innards of that crazy clock.

It was a very basic, inexpensive-looking wall clock that you would buy from Target. If you have any thoughts please let me know. Thank You!! Scottie-TX Registered User. We here understand what you witness, but, "yeah" - is kinda wierd first time you experience it. During normal operation, power is released a tick at a time.These may or may not work for other brands. We do not have any instructions for other brands outside of Howard Miller and Seiko clocks.

Welcome to the world of radio controlled timekeeping technology. We hope you will enjoy the convenience of never having to set your clock again and the confidence of knowing exactly what time it is. During the night your clock will automatically set itself. And nothing keeps track of time more precisely and trouble free than our radio controlled clocks.

Since the beginning of time, man has been fascinated with the measurement of time and has devised more accurate machines to trap and measure time. A team of atomic physicists continually measures every second of every day to an accuracy of ten billionths of a second per day.

Radio controlled clock time setting problem

These physicists have created an international standard, measuring a second as 9, vibrations of a Cesium atom in a vacuum. This atomic clock regulates the WWVB radio transmitter located in Fort Collins, Colorado, where the exact time signal is continuously broadcast throughout the United States at 60 kHz to take advantage of stable long wave radio paths found in that frequency range.

Radio waves at these low frequencies use the earth and the ionosphere as a wave-guide and follow the curvature of the earth for long distances. The built in antenna system will receive the WWVB signal anywhere in North America within miles of Fort Collins where long-wave radio reception is undisturbed.

A microprocessor activates the receiver and processes the time signal from Fort Collins overnight. Through the radio signals, our radio controlled clocks always keep precise time. The changeover from standard time to daylight savings time, and vice versa, takes place automatically with the same precision. Due to the nature of long wave radio signals it is normally not possible to receive a signal during the day so it is best to install the battery late in the evening.

The time zone buttons may be pressed any time after installing the batteries. If multiple buttons are pressed the clock will set to the time zone selected last. If no time zone is selected the clock will default to Pacific Time. Another time zone can be selected during or after the clock has set itself.

Your clock can only set itself to one of the four time zones stated above.

Your clock will no longer observe DST. Atomic Clocks may also be set manually and be very accurate.
