This radio made Song Zhewu's heart bloom, and household appliances are a big money! This is the general trend and trend of the development of the following era. Thinking that decades later, almost all urban and wealthy rural populations would be inseparable from household appliances in their daily lives, Song Zhewu's mood was extremely excited!

With his current strength, it would be a fantasy to make a computer, and even if he wanted to make a television now, it would be wishful thinking, but now it is completely feasible for him to produce a radio.

Song Zhewu knew that the Frenchmen Lucien and Lévy used superheterodyne circuits to make radios and applied for patents, and in 1924 superheterodyne radios began to be put on the market for the first time, and there was now an American-made radio in his headquarters, but he looked at it every day and just didn't think of the financial source of producing radios. It is said that the radio was only popularized in large quantities in 1934, and in his memory, this type of AM radio is now developing rapidly in Europe and the United States, and it is said that it can produce more than 100,000 units a year.

If he vigorously develops household appliance technology, that is to say, as long as he seizes this commanding heights with advanced technology in the early stage, and with his unique and absolutely correct forward-looking surname in the world, he can completely hold the leading position in the field of electronic technology in the field of household appliances.

It's just that the output of more than 100,000 units is too small, and now the number of people who can afford to buy radios in the world is conservatively estimated to be hundreds of millions, and of course, the vast majority of these people with purchasing power are in Europe and the United States. However, if we produce better quality radios, we will definitely export them to foreign countries in large quantities.

Moreover, refrigerators and air conditioners can also be considered. Both of these things are now available in the United States, but they have a huge room for improvement, just like radios. Air conditioning is now only used in large shopping malls and movie theaters, and has not yet spread to households; And it's all water-cooled; He had seen refrigerators at this time in Germany, not only were they bulky and noisy, but the shells were still wooden.

If his factory can produce these kinds of household appliances, then he will be very rich! With his foresight ahead of the times and the low-cost competitiveness of his factories, foreign factories are definitely not his opponents. Although the labor cost in foreign countries is also very low, for example, the weekly salary of an engineer is between 10 and 20 US dollars, but even so, it is still much higher than the labor wage level in China. The wages of several of Song Zhewu's factories are 30% higher than those of domestic enterprises, but even so, the wages of industrial workers are still much lower than those of foreign industrial workers.

If the electrical products he produces are not only inexpensive, but also more advanced, then they will flood the European and American markets, and the rolling dollars and pounds will continue to flow into his pocket. More importantly, he can train a group of qualified industrial workers and technical strength.

Li Minghua saw that Song Zhewu was stunned, thinking that Song Zhewu didn't believe that he and Cui Hao could assemble the radio, so he picked up the soldering iron and quickly soldered the last few wires, connected the power supply, turned on the fast off, and slowly began to tune. After the initial cacophony of noise, the delicate voice of a female announcer gradually became clear in the noisy background. Although the murmur is still clearly felt, there is no problem in hearing it clearly.

Li Minghua said to Song Zhewu regretfully: "This is a mountainous area, and the signal is not very good. ”

Song Zhewu said excitedly: "It's very good, the imported radio in our headquarters is even worse than this, and it still sets up more than ten meters to make an antenna." ”

Li Minghua said proudly: "Our radio must be much stronger than the commander's, this is Lao Cui's own improvement, and the effect is naturally not comparable to the commander's radio." As he spoke, he took a drawing on the table and showed it to Song Zhewu.

"I didn't improve it myself, and I wouldn't dare take the credit for it alone." Cui Hao, who finished the lecture, walked in.

Cui Hao wanted to salute Song Zhewu, but he raised his hand halfway up and put it down embarrassedly.

This is not that he disrespects Song Zhewu, but that Song Zhewu has a strict order that all scientific researchers in the laboratory are not allowed to salute their superiors, even himself.

Cui Hao said: "Commander, this is not something I did alone, this is what I and Minghua calculated together." ”

Li Minghua said with a smile: "Commander, Lao Cui Electric has a lot of knowledge, especially his practical hands-on design ability is very strong, if he is abroad, he must be a very good engineer." And I have an advantage in theory, and you put the two of us together, to put it mildly, it really complements each other. "After that," laughed. ”

Cui Hao also said with a smile: "Minghua is worthy of being a big doctor, with a very deep theoretical foundation, which is only stronger than the professors I was studying abroad. ”

Li Minghua smiled and said to Cui Hao: "Old Cui, let's not praise each other, let's ask the commander to give us a scientific research task quickly." ”

It can be seen that Li Minghua and Cui Hao cooperate very well, and both of them are indeed excellent, which makes Song Zhewu very happy.

Song Zhewu sat down at the table, beckoned Li Minghua and Cui Hao to sit down as well, and said in a tone that could not hide his excitement: "Whether a country's science and technology are developed or not, the current measure is to value the level of industrial development, but thirty or forty years later, at most fifty years, a country's scientific and technological strength and level will be measured by electronic technology. ”

Seeing that Li Minghua and Cui Hao didn't say anything, Song Zhewu knew that they didn't agree very much, but only remembered this point of view. At this time, it is the first period of big industry, and all technologies are for big industry, and they are all supporting roles for big industry. At present, electronic technology is still in its infancy, and even many technologies are still in the exploration stage, and a complete theoretical system has not yet been formed. It is not surprising that they do not recognize the importance of electronics.

"I don't want to say that ordinary people don't agree with this point of view, even you professionals don't agree with it."

Song Zhewu reasoned his thoughts, looked at the two of them and said: "Let's talk about the phone, the current phones are all wired telephones, and because of technical reasons, they can only talk at a relatively close distance and a limited number of objects, and the transmission of signals is limited by line capacity and transit equipment, which is very inconvenient to use." However, with the development of electronic technology, it will be possible for every city to talk to each other, even across the ocean. Moreover, the wired method will eventually be replaced by the wireless method. Decades later, almost everyone will have a compact wireless phone in their pocket, and they will be able to talk to their loved ones at any time, anywhere, and thousands of miles away. ”

Seeing that both of them looked at him in amazement, Song Zhewu continued: "Now there are only telephones that can transmit audio signals, and with the advancement of electronic technology, there will definitely be video equipment that can transmit images in the future." You can imagine what it would be like to be when you sit in the research institute and talk to your peers on the other side of the ocean and exchange research experiences, not only can you hear each other's voices, but also can see each other's every move. ”

"Also, now every piece of equipment in the factory, every production link, is through the workers one by one to start, the need for a large number of personnel, not only the work efficiency is low, but also easy to make mistakes, product quality can not be guaranteed. If the electronic technology and mechanical equipment are effectively integrated, the automatic operation can be realized through the pre-designed program, which is not only efficient, but also the quality is absolutely guaranteed, and the accuracy of the same part can be absolutely the same; There is also the current data calculation, which you two experts should know better, the current manual calculation is not only time-consuming and laborious, but also often makes mistakes, one step of the calculation error, many calculations have to be overturned. If he could compile a large-scale logic circuit so that he could perform calculations automatically through electronic technology, he could do as much as many people do in a year, or even much higher......

Song Zhewu stopped talking, looked at the two people who were trying to think about his words, and said with certainty: "So, I said that although it is the era of heavy industry, the next one must be the age of electronic information." With the continuous development and progress of technology, electronic technology will surely permeate every corner of our lives in the near future, not only military, industrial, agricultural production, but also our clothing, food, housing and transportation are inseparable from electronic technology. It is precisely because electronics technology is so important that I have high hopes for your electronics research institute! ”

Song Zhewu's words made Li Minghua and Cui Hao excited, both of them are experts in electronics, and the bright future of electronic technology described by Song Zhewu should be achievable in their opinion, which cannot but make them excited.

Decades later, when the techniques depicted by Song Zhewu were realized one by one, the two held Song Zhewu in high esteem. When Li Minghua revealed Song Zhewu's remarks in Laiyuan, it immediately caused a blatant uproar in the world, and Song Zhewu was recognized as the prophet and originator of contemporary electronic technology.

Cui Hao said excitedly: "Commander, since electronic technology is so important, we should immediately build some electronic factories, we do not have a factory like this in China, if we have our own factory, the electronic products we produce will definitely sell very well." ”

Li Minghua said impatiently: "Commander, what do you say are the uses of electronic technology in the military? Hurry up and give us a research task from the Institute of Electronics! Lao Cui and I will certainly live up to the commander's high expectations, and we will definitely come up with the research results that the commander needs as soon as possible. ”

Song Zhewu understood the mentality of the two at this time, and said with a smile: "I came to you this time to give you a scientific research task. It's just that after I saw your radio, I had a new idea......
