Don't worry about not receiving the radio signal
Through the radio wave timing technology, whether it is a radio wave watch or a radio wave clock, users often worry that they can not receive the timing signal. Of course, the radio wave is time-sensitive, it can automatically adjust the time, it can be exactly the same as the standard time, so it must be able to receive the standard time. This problem has become the most frequently asked question for customers of French poetry and watch, but it is also the most reassuring for my customers, because the French poetry watches ensure that customers can receive them normally. We will take the clock out for the time test before shipment, which can be correct. Will be packaged and sent out. At the same time, when customers purchase, we will also know the city where they live. If they exceed 1500 kilometers, they will remind customers in advance that they may not receive the signal. So far, we have sold customers from Harbin to Hong Kong in the northeast, and we keep all customers receiving records.
A radio wave transmitting station can cover a normal range of 1,500 kilometers, but can still receive signals within 2000 kilometers. Because the time-wave is refracted through the atmosphere, it can penetrate far. Moreover, because this is transmitted through such a long distance, and through the atmosphere, it is affected by various radio signals (such as radios, mobile phones, etc.) in the air, and the seasonal changes will also change the Earth's ionospheric refraction. Ability also has an impact.
A quartz clock has an error of plus or minus 15 seconds per month, so it is about one second a day. Therefore, our appeal is to let the radio clock be automatically received once a day, and its accuracy is not bad in one second. Therefore, within 1500 km, normal reception is not a problem every day. In 2000 km, the midnight signal is usually the best, and receiving once is not a problem. If it exceeds 2,000 kilometers, it is entirely possible that the time-waves are likely to be successfully refracted by the atmosphere. It is simply not easy to receive success every day.
Therefore, China's radio wave launching station is located in Shangqiu, Henan. This anciently known Zhongyuan area is really the heart of China. It radiates 1,500 kilometers from here and has included the most elite areas in China. If it adds 2,000 kilometers, the northeast and Xinjiang. Most of them are in this range. In this case, it is not a problem to receive once a day, and the radio clock is a good second to Beijing standard time.
Therefore, it is really not necessary to worry about not receiving the Chinese code timing signal. This is a very mature technology. What's more, the French poetry watch also ensures that the clock you buy can receive the signal normally.
