A clear broadcast sound came from the radio, and of course, there were also the specific current sounds contained in the radio, which was inevitable for radio broadcasts. Long-wave radio stations were easily affected by various external environments and even weather, but they made the citizens of Baotou hear it with relish.

Li Qiang and others listened to the radio and were even more focused than when they were in class at technical schools. The teachers had to be more serious about the lectures. The announcer broadcasted the news in a slightly calm tone. The dozen news in the first part were all local affairs in Baotou, including some municipal construction and the welfare of Baotou citizens. Municipal construction will make the city more beautiful and travel is relatively convenient. As for the welfare of citizens, it is basically closely related to the citizens.

Among them, for the sake of broadcasting this radio station, the Baotou government has specially passed a resolution to provide a certain degree of subsidy for the elderly who are unable to work and children under the age of 7 in cities, with the amount being around 5 yuan. Although it is not much, it is a real subsidy, which is very helpful to low-income people or vulnerable people in these cities.

The people's hearts are gradually gathered in such little things. Radio undoubtedly gives people a process of communication. Some people who benefit from this welfare directly say the words that praise Baotou. After all, for many years, ordinary people are the objects of oppression, and no welfare will fall on them. Once there is turmoil, they are the objects of rushing to pay bribes.

Others who have no benefits can also empathize with each other. Whoever has no parents or children can enjoy all this when they are old, provided that Baotou exists, broadcasts and various propaganda are integrated into a whole. This is what Yang Yuanzhao, the initiator, did not expect.

The news continues. The first one takes about 15 minutes, and then there are major events happening at home and abroad, including the Qing court, and even what happened abroad. It is different from other newspapers. Baotou has huge overseas relations. German and American companies have offices in many countries. Sometimes, they directly use some important foreign newspapers to Baotou through telegrams, and then some of them are selected and reported through the radio.

"It's amazing. My family knows everything in the world!" An old man in a jacket said shaking his head. He should be a literati, depending on his age. His family should be working in Baotou, so he brought him here. There are really many such people in the community. After all, the most profitable people in Baotou at present should be those who know Western learning and have a certain foundation. Workers can be senior workers at level 5 or above. Even if they do research, their income is quite considerable.

With a generous income and good living conditions and various welfare in Baotou, more and more people have begun to settle in Baotou. In this era, only a few people are unable to leave their hometowns. Under hundreds of years of oppression, ordinary people have lived too hard, and in contrast, Baotou's life is too rich. In comparison, Baotou's population is also rapidly getting earlier.

The same is true for others. Even some old farmers can't read a word. For most northern people, it is not difficult to understand the official language of the Northern people. The announcer's speech speed is not fast, and it is a slower broadcast, which ensures that most people can understand it. Most of the influence of Baotou is in the north, and the south has recruited some workers, but the number is very small. In the northern environment, it can be understood by barely enough.

Radio is a fun for the general public. A full hour of broadcasting, including the newspaper reading time, became a festival in Baotou. Most people stood in the square to listen to these radios. There were many housewives who delayed cooking and made a lot of food because they listened to the radio. It was not good that families would eat until late tonight, which was considered a pioneering move in Baotou.

Two and a half hours later, the first broadcast ended, earlier than the scheduled time. It was already late at night, with stars everywhere. Yang Yuanzhao was already nervous and unable to do the whole time. The two and a half hours of continuous broadcasting took them most of their energy. Although they maintained their shape, if they were not sitting on the chair, they would not be able to support them at all. He nodded and said in praise: "You are doing very well, keep working hard!"

The three announcers were all excited and received praise from Yang Yuanzhao. This was something that no one could get from many people. They were secretly encouraged in their hearts. Next, they must do better. The three announcers did not expect that this was the first attempt of world broadcasting, which was a regular radio station, the history of broadcasting and radio in the future world, and thus changed.

It was too late at night. Although the lights were illuminated by the broadcast tower, the road down the mountain was not easy to walk. A mountain road that was barely dug has been installed. For announcers, they need to be on the mountain. At present, they only have one group of announcers, and only after the second group appears in the future, shifts will appear. They must persist here until another group of training comes out.

It took almost 40 minutes before I got down to the bottom of the mountain. This side was relatively smooth. The winding mountain road specially dug for up the mountain was also continuing. In the future, motor vehicles and carriages could directly reach the broadcast position.

"Mr. Trass!" Yang Yuanzhao looked at Trass for a moment and said, "The broadcasting matter has come to an end. Experiments on radio transmission and various aspects have also been completed. Then, the next step is to miniaturize the radio transceiver!"

A trace of solemnity appeared on Trass' face. It was not too difficult to complete this theory and test piece, and it was not even difficult to broadcast radio. It was just a merger of a transmitting device and a receiving device. The first experimental radio transmitter made by Marconi was not large in size, because it was just a transmission and reception of an electrical signal. Without considering broadcasting, the analog voice and electrical signal conversion problem was completed a month ago, and more than 20 experimental products were made.

Through these test products, various aspects of radio experiments were repeatedly carried out to achieve relatively good results. In these experimental products, the use of electron tubes was constantly increasing, and therefore, a considerable reduction in volume and weight was reduced. However, to a certain extent, this reduction was already in a bottleneck state, and a small-scale adjustment was possible. Trass knew that if he continued to work hard, the weight and volume would be further reduced, and the weight might reach 30 kilograms. As for the volume, it could be reduced to two-thirds of the current one. However, in this case, it could not meet the requirements mentioned by Yang Yuanzhao. What's more, in addition to volume and weight, Yang Yuanzhao also specifically mentioned the range of reliable use, 2 kilometers, which is already quite considerable. After all, to reduce the volume, the transmission power cannot be too large, otherwise the battery would not be able to withstand it.

Battery is a problem that cannot be avoided. Yang Yuanzhao has not done much research on batteries, but he also knows that batteries have an important role for portable devices such as radios. Take later generations for example. Discussions on electricity can almost fill a university library, and discussions on radios can also fill at least a few houses. However, for batteries, there are probably only a few pages of paper, and even a book is not satisfied with it. As a thing that has a huge impact on industry and many things, its development is not fast. A battery will be used for a long time. Although it is developing itself, it is absolutely hugely different from other categories.

Yang Yuanzhao cannot and cannot take out the batteries of later generations. Those who followed him through time include motorcycle batteries and mobile phone lithium batteries. These things are too high compared to this era. Perhaps in the future, the strength of radio will be improved and Baotou's own strength will also increase, Yang Yuanzhao will invest in it in small batches. Now this is almost impossible, so we need to use existing methods to solve the current problems.

At the beginning of the radio station, Yang Yuanzhao also learned in detail about everything about the radio station. It can be said that he had some understanding of the radio technology device. After considering it, he said: "Some problems can be solved by other methods!"

Tras looked at Yang Yuanzhao with a look of inquiries. In Tras's opinion, Yang Yuanzhao is like him, who has a deep understanding of science. In some aspects, Yang Yuanzhao's accuracy and thoroughness in looking at problems are still above him. In a sense, Yang Yuanzhao is an omnipotent. The entire research institute and more than 50 different projects have gradually developed under the guidance and direct interference of Yang Yuanzhao. Yang Yuanzhao's vision of science and development deeply admires him.

Yang Yuanzhao also saw the radio tower and his eyes lit up. The biggest problem of radio transceivers is actually above power. To ensure sufficient power, it not only requires a larger battery, but also a larger transmitter. As for the receiver, it is relatively small. After having a vacuum transistor, it is very easy to solve this problem. Seeing the radio tower, Yang Yuanzhao suddenly thought of the mobile phones in later generations. The power of the mobile phone itself is actually very small. The reason why mobile phones can freely move around in various places is because mobile companies have set up many base stations. The larger the cover area of ​​the base station, the larger the area it can cover, the better the signal. This seems to be used on radios. This problem is solved by using radios. It is not analog or digital signals, but just a specific radio transmission band, which should be solved. (To be continued, please search for astronomy, novels are better and faster!
