There is a clear broadcast sound from the radio, of course, there is also the sound of the specific current carried in the broadcast, which is unavoidable by the current radio broadcast, the long-wave radio station, which is susceptible to various external environments and even the influence of the weather, but it makes the citizens of Baotou listen with relish.

Li Qiang and others listened to the radio, focused on Cheng dù, even more than when they were in the technical school, the teachers' narration was much more serious, the announcer used a slightly steady tone, broadcasting the news, the first part of the dozen news, are all local things in Baotou, including some municipal construction and the welfare of Baotou citizens, municipal construction, will make the city more beautiful, travel is relatively convenient, as for the welfare of the citizens, basically closely related to the citizens.

Among them, for the broadcast of this radio station, the Baotou government has made a special resolution to provide a certain amount of subsidies for the elderly who are unable to work in the city, as well as children under the age of 7, with an amount of about 5 yuan, although it is not much, but it is a real subsidy, which is very helpful for low-income people or vulnerable people in these cities.

The hearts of the people, in such a little bit of things, gradually cohesion, radio is undoubtedly a process of communication, some of the benefits in this welfare, directly say the words that are beautiful to Baotou, after all, how many years, ordinary fart people, are the object of oppression, any welfare, will not? It falls on them, and in the event of turmoil, it is they who are the targets of the conquest.

Others, no gains. It is also empathetic who does not have parents. and who have no children, when they are old. The same can enjoy this qiē, provided that Baotou is stored in zài, broadcasting and all kinds of propaganda, just like that, the new Baotou is integrated into a whole, which is what the initiator Yang Yuanzhao did not expect.

The news continues, and the front probably occupies 15 minutes, and the back. It is the major things that happen at home and abroad, including the Qing court, and even what happens abroad, unlike other newspapers, Baotou has a huge overseas relationship, German and American companies, with offices in many countries, and sometimes, directly use some important foreign newspapers. The telegram was transmitted to Baotou, and then some of the things were excerpted and reported on the radio through Guò.

"It's amazing, the family knows what is going on in the world!" An old man in a gown. shook his head and said that he should be a literati, depending on his age. It should be his family who works in Baotou, so he was picked up. In the community, there are really many such people. After all, at present, the most profitable people in Baotou should be those who know how to learn from the West and have a certain foundation.

With a good income, Baotou's living conditions and various welfare conditions, more and more people began to settle in Baotou, the people of this era, the real homeland is only a few, hundreds of years of oppression, ordinary people live too hard, and in contrast, Baotou's life, and too rich, compared with the two, Baotou's population is also rapidly early.

Other people are the same, even some old farmers, who can't read a word, the northern official dialect, for most of the northern people, is not difficult to understand, the announcer's speed is not fast, it is a slower speed of broadcasting, to ensure that most people can understand, most of Baotou's influence is in the north, and the south has also recruited some workers, but the number is very small, in the northern environment, barely able to understand.

Radio for the general public, is a fun, a full 1 hour of broadcasting, including the back of the newspaper reading time, has become a festival in Baotou, most of the people, are standing in the square to listen to these broadcasts, there are a lot of housewives, because of listening to the radio, delayed cooking, paste a lot of meals, not good family tonight to eat late at night, it can be regarded as a pioneering act in Baotou.

Two and a half hours later, the first broadcast ended, earlier than the scheduled time, it was already late at night, the sky was full of stars, Yang Yuanzhao faced the three announcers who were already nervous and couldn't work, two and a half hours of continuous broadcasting, so that they consumed most of their body, although they kept their shape, but if they didn't sit on the chair, they couldn't support it at all, he nodded, and said approvingly: "Your watch is very good, keep working hard!" ”

The three announcers were full of excitement and were praised by Yang Yuanzhao, this is something that many people can't ask for, they are secretly encouraging in their hearts, next, they must do better, the three announcers did not expect that this as the first attempt of world broadcasting, it is a regular radio station, and the history of broadcasting and radio in the future world has changed.

The night is late, although the broadcast tower, the lights are brightly lit, the road down the mountain is not easy to walk, a barely dug mountain road, has been installed with lights, for the announcers, they need to be on the mountain, at present Baotou, only they have a group of announcers, the future will be after the second group appears, there will be shifts, they must persist here, until another group of training out.

It took almost 40 minutes to descend to the bottom of the mountain, this side is relatively gentle, and the winding road specially dug for the mountain is also continuing, and in the future, motor vehicles and horse-drawn carriages can directly reach the position of the broadcaster.

"Mr. Truss!" Yang Yuanzhao looked at Truss for a moment, and then said: "The matter of broadcasting has come to an end, and the transmission of radio, all aspects of the real thing, have also been completed, so the next step is how to miniaturize the radio transceiver!" ”

Truss's face showed a trace of solemnity, the radio transceiver, to complete this theory and experiment, is not too difficult, not even the difficulty of radio broadcasting, but just a combination of transmitter and receiver, once Marconi made the first real yàn radio transmitter, his volume is not large, because it is only the transmission and reception of electrical signals, not considering broadcasting, the conversion of analog voice and electrical signals, as early as a month ago, has been completed, And made more than 20 real yàn products.

Through these test products, repeated radio tests in all aspects, in order to achieve relatively good results, in these products, the use of electronic tubes is constantly increasing, and therefore, the volume and weight have been reduced, but now, a certain amount of dù, this reduction has been in a state of bottleneck, small-scale adjustments are possible, Truss knows that if he continues to work hard, the weight and volume will be further reduced, the weight may reach 30 kilograms, as for the volume, It can be reduced to two-thirds of the current one, but in this case, it simply cannot meet the requirements Yang Yuanzhao said, not to mention, in addition to the volume and weight, Yang Yuanzhao also specifically mentioned the range of reliable use, 2 kilometers, which is already considerable, after all, to reduce the volume, the transmission power cannot be too large, otherwise, the battery will not be able to withstand it.

Battery, this is a problem that can not be bypassed, for the battery, Yang Yuanzhao did not have much research, but he also knew that the battery for the important role of portable devices such as radio, take the later generations, about electricity, almost can fill a university library, about the radio, at least can fill a few houses, but for the battery, I am afraid that there are only a few pages, even a book is not satisfied, the battery as a industry, has a huge impact on many things, his development is not fast, A battery will be used for a long time, although it is developing, but it is definitely very different from the development of other categories.

Yang Yuanzhao can't, and can't take out the batteries of later generations, and follow him through the motorcycle battery, as well as the lithium battery of the mobile phone, these things, compared to this era is too high, maybe in the future, the strength of the radio has improved, and the strength of Baotou itself has also risen, Yang Yuanzhao will invest in small batches, now this is almost impossible, then we must use the existing methods to solve the current problems.

At the beginning of the radio station, Yang Yuanzhao also had a detailed understanding of the radio station, so to speak, he had some understanding of the radio device, and after thinking about it, he said: "Some problems can be solved by other methods!" ”

Truss looked at Yang Yuanzhao, his eyes were full of inquiry, in Truss's view, Yang Yuanzhao is the same as him, are people with deep insights into science, in some aspects, Yang Yuanzhao's accuracy and thoroughness of looking at the problem, is still above him, in a sense, Yang Yuanzhao is an all-rounder, the entire research institute, more than 50 different projects, are under the guidance and direct intervention of Yang Yuanzhao, only gradually developed, Yang Yuanzhao's vision of science and development, let him deeply admire.

Yang Yuanzhao also saw the broadcast tower, only to see the radio transceiver, the biggest problem, in fact, is still above the power, to ensure enough power, not only need a larger battery, but also need a larger transmitter, as for the receiver, relatively small, after having a vacuum transistor, it is very easy to solve this problem. Seeing the broadcast tower, I don't know how, Yang Yuanzhao suddenly thought of the mobile phone of later generations, the power of the mobile phone itself is actually very small, the reason why the mobile phone can move freely in various places is because the mobile company has set up a lot of base stations, the larger the coverage area of the base station, the larger the area that can be covered, the better the signal, this seems to be also used on the radio, with the help of radio to solve this problem, and it is not an analog and digital signal, but just a specific radio transmission band, which should be able to solve.
