Qingshan, which belongs to the Yinshan Mountain Range, is regarded as a residual vein, which is not directly connected to Yinshan, but is a part of the geology. Because of the expansion of Baotou City, it has gradually approached the urban area of Baotou, and has almost leaned next to the green mountain.

Recently, Qingshan has become the focus of attention of Baotou citizens, because a sword is like a sword, straight into the skyline tower, on the top of the tall Yin Mountain, it is particularly eye-catching, layer by layer building, and higher and higher, standing on the roof of the house, you can see the rising tower. Many people are discussing what this tower is doing and what it is for.

There are all kinds of things, some say that it is a completely iron stupa, and only the stupa will be so high, some say what is the lightning rod, some simply say what is the treasure, used to ward off evil spirits, especially with the gradual completion of the tower, there are even some people in action, which has aroused the interest of Baotou citizens, some people have even formed a habit, every time after getting off work, they will stand on a high place to see what is going on.

Now Baotou is a standard industrial city, about half of the personnel, are workers, in the spare time, there are really not many recreational activities, so Baotou Daily, in order to get the broadest market in Baotou, the total sales of Baotou Daily, has reached 200,000, which is just over a million cities in Baotou, extremely amazing, it can be said that the tentacles of the daily newspaper have penetrated into every corner of Baotou.

With the publicity and entertainment, especially after the real establishment of the government, the community began to organize a series of activities, which made everyone's daily activities begin to be colorful, and people gradually participated in community activities in addition to learning, making Baotou slightly different from other cities in China.

On the top of the tower, which was named the broadcasting tower, Yang Yuanzhao was building a staircase slowly upward, and it was not a separate tower crane, of course, he would not make that kind of iron ladder, which was too laborious, and dangerous, the announcer and some staff had to go up and down the tower every day, and the ordinary weather was easy to do, in case of rain and snow, or frost weather, it was definitely a dangerous thing.

Below the broadcast tower, the area is relatively large, so Yang Yuanzhao set up a steel staircase of less than 4 square meters here, circling upward, enough for a person to slowly go up, in this era, there is no more reliable elevator, high on the mountain, simple, can be used for the transmission tower wires, can barely come up, large-scale use is somewhat difficult, besides, the development of elevators, in foreign countries is relatively broad, there are only some large cities in China, there are some small-scale elevators, on the basis of not preparing to go on the skyscraper, Yang Yuanzhao has not studied this thoroughly.

The equipment has already been obtained, and has been installed, this is Truss after more than 20 transformations, the high-power radio station made zuò, using a variety of tubes more than 50, and part, is Truss according to the role of the tube, designed for the use of radio transmitters, these are also entrusted to Baotou Electronics Factory, to be precise, is the electronic growth in thousands of times, even tens of thousands of times of the real yàn, the production of a variety of tubes, Then Yang Yuanzhao chose the best one from the middle, which was copied by guò, and the stability was quite good, and the time of use had exceeded the record of the electron tube.

The power of the transmitter is powerful, the device at the receiving end is even smaller, only the size of a brick, which uses a superheterodyne circuit, just this, it is amazing enough, you know, the real history, the radio of the superheterodyne circuit, will be born after 3 years, which can also be seen that Truss's tough, not only uses this circuit, but also uses alternating current instead of direct current, that is, the radio can be powered with the help of an external power supply, without the battery, this fixed range dù above, Reduce the difficulty of radio promotion, high-performance, reliable tubes, so that the radio signal is more excellent than the ore radio, there is an ore radio in the real room, that is the initial real product, to complete the design, after the tube is used, when the promotion, there is only the tube.

Yang Yuanzhao is not familiar with the electronics industry, Yang Yuanzhao does not know, under his promotion, almost across a class, it is estimated that he knows, he will not care, the development of the electronics industry, the tube is only the lowest, the future of semiconductors, transistors, and even large-scale, ultra-large-scale integrated circuits, is the real development direction of the electronics industry, and radio and radio stations, just one of the many applications of electronics.

A few staff members in white coats are debugging a strange machine, Yang Yuanzhao is not a hobbyist, he requires that the machine that comes out of the machine must be quite practical, that is to say, it is not the kind of room that is similar to the real room, or something tested, it must take into account stability, so the machine is much larger than all radio transmitters, compared with a few years ago, the transmitter that the United States released the Bible, the power is at least 30 times larger, and the performance is stable. It can convert voice into radio signals, transmit them, and then pass through the receiving end and convert them into human voices, which gives this machine the ability to use basic performance, publish broadcasts, and set up radio stations.

"The tests are all done!" Truss asked, these are all radio research institutes, among them are 7 foreigners, from different countries, are radio enthusiasts, among them there are 2 Chinese, the last one, is a native Chinese, he did not even have the experience of studying abroad, completed middle school in Tianjin, entered the northwest through the guò channel, and because of his outstanding talent, entered the power laboratory, has been followed until now, has become an independent researcher, specializing in radio transmission and research, is Truss's more important assistant.

This person's name is Jiang Zhenhua, and he is also the most valued by Yang Yuanzhao, and the future electronic reality is that he and the two Chinese are definitely the dominant ones, and even the future status will be one of the main leaders in the Baotou electronics industry.

"The test has been completed, and the transmitter in the city has also fed back the signal." Jiang Zhenhua nodded and said.

In addition to this tower, in the research institute in the city, there is also a set of machines, which can pass simple electronic signals and carry out some transmission, without letting people transmit information back and forth, this already has the prototype of remote interconnection and radio distribution, but this volume has to be reduced, at present, in another research institute other than radio broadcasting, the research on portable radio transceivers is also continuing, and the current production is within 2 kilometers. A more reliable portable radio transceiver has come out, about 35 kilograms, which is very different from Yang Yuanzhao's expectations, in Yang Yuanzhao's mind, the weight of a radio transceiver should be controlled below 15 kilograms, as for the reliable transmission distance, it should reach about 15-20 kilometers.

Such a distance, for a campaign, should have a certain tactical role, the front and the rear are separated by 15-20 kilometers, there are several generator sets, interconnected, able to control a fairly large battlefield area, a certain distance dù on the ground there is a communication operation and the rudiments of an information station.

The development of science and technology, every step forward, needs considerable development, now, Baotou only solves the problem of having and not, the future road, still need to continue to work hard.

"Have you found an announcer?" Yang Yuanzhao asked.

"It's all in the other room." Jiang Zhenhua pointed to the side, in this room of only about 80 square meters, in addition to the largest is used as a broadcast room, there are two or three small rooms, used for dressing rooms and some other functional rooms.

The announcer is definitely selected by Yang Yuanzhao according to the situation of later generations, for Baotou and for the whole world, it is a pioneering achievement, with professional, standard broadcasting, but this standard Cheng dù, Yang Yuanzhao thought about it for a while, and finally decided to use Mandarin, the dialect of the north, which is not much different, not as complicated as the south, ten miles and eight villages, there will be a situation where you can't understand it, but Yang Yuanzhao has decided that Hanyu Pinyin, Hanyu Pinyin, is based on Beijing official dialect. There are not many people in Baotou who can really speak very well, and at the beginning of the decision to build a radio station, Yang Yuanzhao began to train this, with the help of Xinhua dictionaries, so that they can change little by little, and they can barely speak clearly.

In the real history, when the radio station first appeared, there were not so many at all, and there were many dialects and slang in various places, that is, when the commercial operation and the radio station entered the government's field of vision, it gradually became a standard broadcast, so as to ensure that these words could be understood within the scope of the broadcast. Yang Yuanzhao, who came from the era of consulting in later generations, decided to use the most standard at the first time, and the problem would arise in the future.

Three announcers walked out, one male and two female, the current Baotou radio station, just a grass head team, under Yang Yuanzhao's construction, there are only three columns, news columns, domestic and foreign newspaper summaries, and a drama program, such as with the help of tape recorders, in theaters around the country, recorded some famous singers, and there are local colors, Jin Opera, Northern Bangzi, Pu Opera, etc., because of the broadcast conditions, only ask others to record it, and then broadcast, This had to use the equipment brought by Yang Yuanzhao from later generations, mobile phones.

At that time, tape recorders were only available in a small number of families, and mobile phones had integrated the functions of most household appliances, because of the confidentiality relationship, mobile phones, this thing, only a few of the most cronies were managed, once recorded, instilled into the record, with the help of the record, for playback, in this way, the mobile phone only used the basic use, and it took a few weeks of hard work to finally get some mainstream repertoire of contemporary drama masters, as well as some local repertoire, which were engraved into records and placed in the broadcast studioto prepare for today's broadcast.
