Alfaso Far Sang Radio Clock? Can anyone tell us what the good stuff is?

Radio clocks are commonly known as (radio controlled clocks) in English, and some people also called this kind of clock atomic clock in the early days, because the official and most standard clock in every country in the early days was timed through the ** of cesium (cesium) atoms, so it is customary to call the clock with high time precision as an atomic clock. Because the timing equipment of the timing signal transmitter station is made of rare cesium atoms, there is only one second error in 100,000 years, so it can be maintained at the standard time almost permanently. Generally, quartz clocks have an error of 15 seconds every month, but the radio-controlled timer transmits a standard clock through such a base station and receives a standard time signal from the radio-controlled clock, which can match the standard time for one second, which is enough for daily life and business needs.

Let's take a look at this diagram first.

I just returned to Dandong from Daqing, and to be honest, my watch can receive signals every day at night at home and I don't need to put any position.

But when I went out, I realized that the signal was not very good outside.

I stayed near Daqing Railway Station for two days and a day and did not receive the signal, hehe, I also saw the card in the shopping mall not far from the train station has my one, but it is not discounted, ask the sales lady that the signal here in Daqing is not too good, said that you can manually collect the wave in the open outside, heh. In addition, I didn't receive it in Harbin for two days, I didn't receive it for a day in Shenyang, and I didn't automatically receive the wave when I went out for a week and a day.

My table is the EQW M1000 Quotient Chubo. Hehe, Shang Qiubo is not very good.

Two days can't explain anything, just to give you a reference, look at the map, theoretically Daqing is 1500km away, but as long as it is within 2000km, it can also receive waves. It depends on the location of your home. In addition, you can try the Japanese wave.

Theoretically, it can be received globally.

CASIO is the first in the world to launch a "6-station radio watch" that has the function of receiving 6 radio waves around the world, corresponding to Coordinated Universal Time. It can receive standard time radio signals from China, Japan (Fukushima base station, Kyushu base station), the United Kingdom, Germany, and the United States, and automatically correct the time. Casio's original solar-powered radio wave technology, which can receive all six frequencies, has brought new advances in radio timekeeping.

However, even within the effective range, the reception effect of radio waves may not be received due to conditions such as season, weather, time zone, and buildings. When the radio signal cannot be received normally, the radio watch can still operate with the accuracy of a quartz watch (within plus or minus 20 seconds per month). China Standard Time [China Standard Time] is based on the [cesium atomic clock] with an error of one second over 100,000 years.

It is managed and published by the National Time Service Center of the Chinese Academy of Sciences. In China, Casio radio-controlled watches automatically receive radio signals from [China Standard Time] every day, truly achieving high-precision timekeeping. Radio Wave Reception Principle The standard time signal transmitted by radio waves is received through the high-sensitivity receiver built into the watch, and the watch time is automatically calibrated.

The time displayed by the watch is precisely synchronized with the local standard time, and the high-precision timekeeping is truly realized.

Let's take a look at this diagram first.

It seems that you can only receive signals from Japan, and whether you can receive them depends on your position. It's not good to say, the signal is generally better at night.
