196: The world's first portable radio station

The arrival of this batch of weapons and equipment in Jinzhou was still four hours later than Qin Chunfeng's prediction, and by the time they arrived in Jinzhou, the sky was already bright.

The officers and men of the 18th Division stationed in Jinzhou also got their weapons, and the gap of the 18th Division was 12,000 rifles, that is to say, they only had 6,000 rifles before this division.

Although it was a few hours later than expected, the good news was not without it, there was no war on the front line, and the situation was still so deadlocked.

If you go further, there may be danger at any time, so Qin Chunfeng can only let those people who have been temporarily recruited return to the capital with ox carts and carriages, and as for the troops, he sent a squad of soldiers to return to the capital with a livestock book, and after handing over this record to Wang Shuqi, he returned to the army.

Twelve thousand rifles were unloaded at once, which was much lighter for the rest of the transportation task. Even without the need for any vehicles, they were able to quickly transport these weapons to the front line.

So, according to the proposal of Cheng Min, a staff officer of the regimental headquarters, the 10th Regiment was to be divided into three parts, of which the first battalion went to Shengjing with 2,000 rifles and the corresponding ammunition to replenish these rifles, and the second battalion went to Haicheng with 2,000 rifles to replenish the 19th Division stationed there.

Qin Chunfeng personally led the 3rd and 4th battalions, carrying 2,000 rifles to Liaozhong to replenish weapons and ammunition to the 21st Division in Shandong.

After sending the equipment, the second battalion rushed from Haicheng to Liaozhong to join the regimental headquarters. The first battalion joined the regimental headquarters after Sheng Jing took Wang Sirui's order.

Because of Wang Sirui's strong support, Nikola Tesla, after coming to the Far East, went from the initial disappointment to the later acceptance, and now he has stopped complaining about anything here.

It can be said that this poor country in the Far East is changing Nikola Tesla's subconscious little by little.

At the beginning, he was indeed frightened by the desolation here and wanted to leave, but what followed was Wang Sirui's strong support. As soon as you open your mouth, a large number of workers will come to you in a short time.

These workers are even more reserved for Nikola Tesla, they will not have any complaints, and they will work harder than anyone else.

They only want to be recognized by Nikola Tesla, because only then can they be left to continue this job, a job that can bring food to their families, or other things of life.

They don't complain about you, although they occasionally point fingers at Tesla and his team in private.

Tesla was not disgusted by this, these natives living in the Far East had never seen foreigners, and it was normal to point fingers.

It can be said that all this is developing in a good direction, but the only thing that makes Tesla a little difficult to accept is that these people are too stupid.

Every work they do has to be done by someone to direct it, and you tell him what to do in this step, what to do next, and what to do in the end? It's all in vain, because they can't understand what you mean, and you can only teach them yourself, step by step.

And this, to some extent, also affected Tesla's experimental process, but when I thought of Wang Sirui's strong support for him and some of the insights he put forward, Tesla unconsciously gave up the complaint in his heart.

Although he wanted to try the method Wang Sirui said, Tesla still felt that it was more reliable to do it step by step, and he had to complete this step to prove that his idea was reliable, and then he would experiment with the idea proposed by Wang Sirui.

That's right, Tesla is going to build the famous Wordencliffe Tower, but because the location of the experiment was moved to distant China, and Tesla named this giant signal tower Huaxia Tower in order to thank Wang Sirui for his support.

However, what Tesla didn't expect was that it was delayed too much time because it needed to seek funding everywhere in history, and finally let the Italian Marconi complete the radio experiment ahead of Tesla, which eventually led to Morgan's withdrawal, causing Tesla to fall into a financial crisis.

And this time, because of Wang Sirui's strong support in terms of funds, Tesla has grabbed some time a little, and now, Huaxia Tower has not yet been completed, but Tesla is a little impatient.

On this day, Tesla asked his assistant to climb to the top of the unfinished tower, where he installed the previously made wiring equipment, and then he led people to a few kilometers away to conduct the first experiment.

Tesla, who installed and debugged the equipment, stood at the bottom of the Huaxia Tower and did the first experiment, and the results proved that the tower is currently working normally, and he can send out normal radio signals.

Immediately afterward, Tesla ran to a distance of one kilometer and continued the experiment, but when Tesla ran three kilometers away, he found that he could no longer receive the signal from Huaxia Tower.

After repeated verification, this made Tesla a little disappointed, so Tesla ordered people to continue to build Huaxia Tower, and at the same time led his team to carry out renovation research on Huaxia Tower.

Although the final experiment of Huaxia Tower did not meet Tesla's ideal expectations, the facts also proved that Tesla's idea was correct.

Since he can transmit the signal to a place two kilometers away, then theoretically speaking, it can also be transmitted to a farther place, and there must be an error somewhere in between, or some unreasonable arrangement in the number.

Tesla and his team are trying to find out where these problems are, and then go to technical PR and finally complete their great experiment.

Of course, while studying Huaxia Tower, Tesla has not forgotten Wang Sirui's suggestion.

Although in the eyes of future generations, Wang Sirui's proposal is equivalent to saying nothing, but in the eyes of Tesla, Frankenstein, this is a great proposal.

Wang Sirui proposed to change the current wired telegraph to wireless telegraphy, and set up a telegram with a large power, and the transmission of signals can be completed by using antennas, and the other sub-terminals do not need such a large power, they only need to complete the signal transmission between the sub-female ends.

Its principle is the same as the current Huaxia Tower, the difference is that he has reduced the size of the Huaxia Tower, and it is easy to carry and can be used for military communication on a large scale.

Although Wang Sirui is ignorant of the transmission principle of radio, at least Wang Sirui still knows that the raw materials of those antennas are made of aluminum.

In fact, this is not only Wang Sirui knows, in later generations, almost everyone is very clear about this principle, at that time, there are always snowflakes on the black and white TV set at home, and then a can of Coke or Sprite will be found and placed on the antenna, so that there will be no snowflakes on the TV, or the number of snowflakes will decrease, etc.

Because the current experiment is not ideal, Tesla decided to use aluminum for the equipment on the Huaxia Tower for an experiment, but it is obviously not easy to get a large number of suitable aluminum.

Tesla didn't think about the ease of his decision, but told the commander of a battalion responsible for keeping them safe, and then the battalion commander was responsible.

In the end, after a busy week, Wang Shuqi finally found a batch of aluminum, and processed it through the steel plant, and finally sent it to Tesla, only to find that the quantity was much less than expected.

However, this did not seem to affect the current experiment, so on the eighth day after the first experiment, Tesla conducted a second experiment.

This time, the height of Huaxia Tower is about ten meters higher than that of eight days ago, plus the equipment has been replaced with aluminum, and the sub-end has also been replaced with an aluminum receiver.

As a result, the results of the experiment were much better than before, this time, Tesla could receive a very clear signal from a distance of 10 kilometers, but the signal would be very unstable if it was further away.

And this experiment finally proved that the signal tower is better with aluminum, and the reason why it can not be transmitted to a farther place must be because there are still some problems with these devices.

Tesla seems to have fallen into a certain circle, and Wang Sirui didn't expect this. If Wang Sirui could think more about the signal towers of the telecom operators in the future, Tesla would not be so depressed.

After half a month of research, Tesla still didn't have any inspiration, so he decided to put aside the research on Huaxia Tower for the time being, and instead studied the project proposed by Wang Sirui, hoping to find some inspiration through this project.

The size of the cable telegraph is not large, but it cannot hold many fragmented parts, which also brings a lot of trouble to the long-term movement.

Regarding this problem, Wang Sirui also proposed a solution for him, that is, these parts can be packed into a box, and the volume can be reduced as much as possible, leaving only an earpiece for receiving signals and a transmitter for sending signals.

Tesla eventually decided to dismantle the two cable telegraphs for this experiment, and the cable telegraph was quickly transferred by Tesla and his assistants to a rectangular wooden box about 50 by 30 by 30 in length, width and height, and then modified the cable receiver to use an aluminum antenna instead of a wired line.

Eventually, at a distance of about 100 meters, Tesla completed the first experiment with a wireless telegraph machine, and the experiment was successful.

However, the signal seems to be a little unstable, the receiving party only received about 70% of the code, and about 30% of the code was lost, of course, it was not lost, but the code was lost due to the receiver not being able to hear the signal clearly.

However, this problem was solved by Tesla's use of antenna bifurcation, which is based on Wang Sirui's opinion, in fact, Huaxia Tower also uses the same method.

In this way, the world's first portable wireless telegraph was successfully tested, and although it was very unstable and difficult to be used in actual combat, at least in the field of portable radio, it was a great achievement. (To be continued.) )
