Nowadays, these radio devices have not only improved in function, but are not much larger in size.
Due to the special needs of Morgan and others and limited by technology, their radio devices were basically shortwave devices.
But the advantages of shortwave are very significant: first, the shortwave radio station is very convenient to set up, and the antenna is not too long; in addition, the most important thing is that shortwave radio can achieve long-distance communication.
Theoretically, it relies on the refraction of the high-altitude ionosphere, and its propagation distance is very long. Global communications are not a problem, and it can achieve the so-called
"Global". Of course, this is only a theoretical propagation distance. If you want to effectively transmit information, you also need to consider power.
However, it is currently in the initial stage of radio. The electromagnetic environment is very clean and electromagnetic interference is almost negligible. Under an ideal environment, a shortwave radio station with very low power has good communication distance and quality.
Tesla borrowed Li Yu's electronic triode technology to amplify circuits, which was a revolutionary advancement for radio.
The power of the radio device made this time is about 10w. Although it doesn't sound big, under the current good electromagnetic environment, covering the entire North China is not a problem.
Li Yu came to the study, wrote a letter to the newspaper, and sent a report saying that he was going to open a concert at the Liuguo Hotel in Dongjiaomin Lane.
"Product Launch". Li Yu also sent a special telegram to Beiyang. They would probably be very interested in this.
The Liuguo Hotel is a very impressive hotel. Although its status is not as good as that of the Beijing Hotel, it is located in the special Dongjiaomin Lane and has witnessed many historical events. The earliest negotiators of the Northeast Yiqi lived in the Liuguo Hotel.
For a long time after that, it was a special guest house of the Ministry of Foreign Affairs, and ordinary people could not enter. After it was reported in the newspapers, the embassies in Dongjiaominxiang were indeed interested. After all, this was something appreciated by top financial tycoons Morgan and Rockefeller in the United States.
Coupled with Li Yu's current supremacy in the scientific community, it is even more exciting. The British ambassador, the Japanese ambassador, the German ambassador, the French ambassador, the Russian ambassador, etc. all came either themselves or sent representatives to visit.
The one coming from Beiyang was Tang Shaoyi. Tang Shaoyi smiled after seeing Li Yu and said: "Brother Shucai! I have seen so many ministers, what big move do you have this time?" Li Yu said: "It is a kind of radio equipment, I think Beiyang will be interested. "
"Radio?" Tang Shaoyi had never heard of this name. Li Yu said: "It is a device that can transmit messages without the need for telegraph lines."
"Oh?!" Tang Shaoyi said in shock,
"Is there such a magical thing?" Li Yu said: "This is the power of science." Tang Shaoyi praised: "I really saw you right." Li Yu added: "If Tang Daotai is interested later, you can Just take one to Beiyang and try it out." Tang Shaoyi said, "I owe you another favor." Li Yu said, "I also owe you a favor, Tang Daotai." Tang Shaoyi asked, "You owe me?" Li Yu had already graduated from De Ling. After knowing that Tang Shaoyi had gotten rid of the haircut incident, he pointed at his hair and said, "This." Tang Shaoyi smiled and said, "So you already know. It's a trivial matter, nothing to worry about."
"This can't be done," Li Yu said,
"And wireless devices are indeed very useful, not only in daily life, but also in the military. Daotai will know when the time comes." Telegraphs have actually played a big role in the wars of the late Qing Dynasty. What can this thing be compared to? Eight hundred miles is too fast.
Tang Shaoyi said seriously: "I understand." Li Yu whispered to him: "Tang Daotai, we will act according to the situation in a moment." Before Tang Shaoyi had time to ask what was going on, the waiter from the Liuguo Hotel came over and said: "Master Imperial Master, I am We're almost here, you can start." Li Yu walked into the hall, where ministers or representatives from various countries were already sitting below.
He laid out the radio device and began to introduce its function: "You must all know the telegraph and use it to communicate with the country. A year ago, the telegraph line was just laid in the Pacific, but the equipment in front of you can Get rid of the shackles of telegraph lines and be able to send and receive messages anytime and anywhere." This kind of
The function of "sending and receiving information anytime and anywhere" is almost a killer function for ministers stationed abroad. Upon hearing Li Yu's words, many people immediately couldn't sit still: "Can its transmission distance reach Europe?" It was the British Minister Sir John Sudworth.
Li Yu said: "If we can build a few base stations in the middle, it will be no problem." Now Britain has no shortage of colonies. Sir Sa Daoyi thought it was interesting when he heard it.
"If this is the case, I will be extremely interested in purchasing it." Li Yu said: "Mr. Morgan in the United States has already used it in Europe to receive news from the United States."
"You rely on the equipment that you don't have a telegraph line in your hand?" Japanese Minister Uchida Yasuya asked. Li Yu said: "Yes." Uchida Yasuya asked again eagerly: "If it is from Japan to Beijing, can it also be used to contact Beijing?" Li Yu replied: "Yes."
"吆西!" Uchida Yasuya couldn't help but stood up and looked at the radio equipment in Li Yu's hand.
"Great!" Li Yu demonstrated to them the sending and receiving method of this set of equipment. It already has preliminary mobile radio functions.
Uchida Yasuya didn't wait for Li Yu to finish the demonstration and said, "I want to buy it! How much will it cost? Please give me a price." British Minister Sa Daoyi said: "Mr. Li Yu hasn't finished the demonstration yet. Minister Uchida must be a little anxious." Uchida Kang Zai knew that this thing was not easy to make. The technical content was there, and it was basically the communication ceiling of the early 20th century.
The key point is that Japan's current embassy in China also plays the role of an intelligence agency. Uchida Yasuya himself has close contact with Kawashima Naniwa of the Black Dragon Society and Japan's first-generation intelligence chief Nobujun Aoki.
They often need to contact their domestic base camp and have very high demands for communication. Li Yu actually grasped their thoughts, and his target today was the Japanese people.
Li Yu was not afraid of selling to them at all, because unlike wired telegraphy, signal modulation was very difficult and there were considerable technical barriers.
Each special equipment will have a special coding system given by Li Yu, and they will not break this technology for many years.
Although it may seem very simple in later generations, it is currently a typical information gap and dimensionality reduction attack. Even if they can do encryption just a few years later, they will be able to produce cryptographic talent by then.
Li Yu only needs to have a special receiving device to know the Japanese Xiao Jiujiu without anyone noticing.
Damn it! You have to use some cheating methods to trick them, otherwise you have studied science and engineering for so many years in vain.
Japanese Minister Yasuya Uchida said: "You don't have to listen to the end, I have already done some research, sir, that's the price." Uchida's approach aroused the dissatisfaction of other ministers, but Uchida insisted on it, because for Japan, the demand for intelligence is now getting higher and higher. It's getting more urgent.
Seeing that he insisted on this, Li Yu had no choice but to say: "The cost of manufacturing and transportation is very high, and the output is very low now. There is only one unit at the moment, and it costs 2,000 silver dollars." This is a high price, much more expensive than what was given to Rockefeller, but it is still expensive. It makes sense, because this system can send messages, not just receive them.
The British Minister Sa Daoyi was the first to say: "I want it." The British's desire to control the colonies was also not low.
Uchida Yasuya said dissatisfied: "I asked about the price first." Satoyi spread his hands and said: "Everyone present can buy it." Uchida Yasuya said: "Then I will add 500 silver dollars." Satoyi smiled and said: "Minister Uchida should treat it as Is it an auction? Interesting, I'll accompany you and add 500 silver dollars." Their thoughts were the same as those of Rockefeller and others at that time. They had the reason to get it as soon as possible and would not care about the premium of several hundred silver dollars.
Uchida Yasuya raised his hand: "Continue to add 500 silver dollars." Li Yu looked a little funny, but he didn't expect them to start fighting.
Not to mention some of the hunger marketing strategies I personally saw back then were really useful. Tang Shaoyi in the back was holding a cigar and taking some time to watch the excitement.
Sa Daoyi got angry: "I'll add 500 more!" These people had 500 silver dollars in each hand, which was quite generous.
Uchida Yasuya said: "Don't argue, I'll pay 8,000 silver dollars!" The price has been raised to four times. Sa Daoyi has participated in the auction and is reluctant to increase the price, because Uchida in front of him is like a gambler.
Besides, Britain and Japan are now in an alliance, and we don't want to push him too hastily. Uchida Yasuya finally breathed a sigh of relief when no one responded. It was over budget, but he was willing to do his best for the cause of the Empire of Japan.
Unexpectedly, Tang Shaoyi took a puff of his cigar at this time, raised his hand and said: "I will add another 1,000 silver dollars." Uchida Yasuya almost vomited blood, who is he!
He gritted his teeth, knowing that the current situation between Japan and Russia was already very tense and could not be delayed, so he said bitterly: "I will add another 3,000 silver dollars. Does anyone want to add more?" Tang Shaoyi took a long breath of smoke and said: "Please, Minister Uchida." Originally, The price of 2,000 has been raised a lot.
Even if Uchida Yasuya feels a little wrong and a little bit shortchanged, he can only accept it. Li Yu smiled and said: "Congratulations to Minister Uchida." Uchida said: "Please show me how to operate it again." A set of radio equipment has two pieces of equipment, mainly the setting up of the radio station and signal modulation. Li Yu explained to him again After a moment, he said: "There is also an instruction manual here. If you study it carefully, you will be able to master it in a short time." Uchida Yasuya listened very carefully and carefully took everything before leaving.
Unexpectedly, when Li Yu went out and was about to leave, the Russian Minister Resal hurriedly came to him: "Your Excellency, I'm sorry, I just arrived." The Russian Minister was not present just now, but a counselor from the legation came. After seeing the Japanese buying it, he quickly went back and told the Russian minister himself.
The minister learned the price from the counselor, so he asked, "Can I also order the same equipment at the same price?" Li Yu pretended to be wrong: "Yes, yes, but the delivery time needs to wait." The Russian minister said: "I can add more funds, as long as Your Majesty the Emperor can provide it for us." Li Yu paused for a while and then said: "Okay." The Russian Minister said happily: "Thank you, Your Majesty the Emperor!" Li Yu just had to give these powers some sweetness. , making them think that they can only buy good advanced equipment and protect themselves. Otherwise, if they hide it too much, I really don’t know what extreme things the Japanese will do.
After all, now that the Japanese have set their sights on themselves, they must adopt some strategy. The best way is to rely on brains and information differences to control the other party first.
However, whether you should say it or not, act like a fool in front of these people.
The "profiteer" really doesn't feel any guilt at all. But Li Yuding's 2,000 silver dollars was actually quite reasonable given the lack of production capacity, and the subsequent price was something they were willing to increase.
Who told them to hide so much dark greed in their hearts.
