Yeah?Roland couldn't help but be happy. When Barov's tone was clearly not just the simple construction of the facilities, did you also hear the signal sound?
The so-called tower project is the first step in the radio communications plan. In order to meet the huge antenna required for long waves, the Ministry of Construction has set up a nearly 50-meter-high transceiver tower in Beiposhan and Yinguang City.
More than half of the towers are only the size of a person's body, so from a distance they look like a long and thin needle.
With the retractable hydrogen balloon tow metal wire, the antenna length can reach up to more than 100 meters.
In terms of construction difficulty alone, it does not have much praise, but the communication tower is a system project, and the transceiver equipment located below the tower is the focus.
Since electromagnetic waves will inevitably be emitted many times during the debugging process, even if it is a messy signal, it is normal to be captured by the other side in this world without any interference.
That's right, Your Majesty.Barov replied excitedly that it does currently have some kind of wonderful reaction, as you said.It's just...I don't know if that was caused by Yinguang City.
I think this question will be answered soon.Roland pondered for a moment and notified the ministers of the Executive Office to go with them. They should not be willing to miss this opportunity to witness history.
……
After several years of development, Beiposhan is no longer the steep mining area with only a few narrow mountain roads. The wide cement roads and railway tracks are built along the slope, and it only takes a quarter of an hour to reach the top of the mountain by train.
Not far from the iron tower, there is a row of simple red brick bungalows built, and the low eaves are covered with ice ridges, which looks far less grand than the new factory buildings on the south bank of the Chishui River.
As far as appearance is concerned, it is difficult for anyone to associate it with the new era.
Walking into the house, Anna was directing several Shamen from the Yuan Qiwu Club to do the final preparations. When she saw Roland, she secretly made a gesture of proper performance, and then she went to work seriously.
Roland couldn't help but grin.
As early as the radio plan was set, this matter caused heated discussion in the Executive Office.
Most people can clearly realize what kind of change the project will bring to the human world.
If the message can be transmitted, it will be a huge enhancement in terms of both the strength of war and the control of Wudongcheng.
Wired telephone, flying messenger and listening to the sign prove that under the combined effect of the three, the old noble forces of Grayburg had hardly found any chance of making a comeback. Many officials had thought that centralization would be a long-term and repetitive process, but the fact is that after they were overthrown by the First Army, they have not caused any waves so far.
The reason is that in the face of efficient information transmission, the nobles will be wiped out by the Second Army and even the police force as soon as they show a little sign, and they will not even leave any room for brewing and development.
However, the phone has a wire at least, and the latter two are related to magic, which officials can barely understand.
But the tower project not only does not have any line connection, but also has a stronger theoretical effect than magical creations, which is really incredible.
Although there is a basic introduction to electromagnetic waves in primary education textbooks, learning is learning, many people still have doubts about such invisible and intangible things.
In a sense, it is more than imagined than a biplane.
Of course, this kind of hot discussion will not affect the actual progress of the project. After all, under the guidance of Roland, there are too many things in Winter City that can be called a miracle in recent years. Even if he suddenly announced that he would take the Red Moon, the Executive Office would do his best.
But radio is not his expertise after all, and his grasp is not as big as that of R&D mechanical equipment. This set of transceiver devices is completely replicated from the prototype of the Grayburg Design Bureau, and no one knows the actual effect.
With Anna's gesture, he finally didn't have to worry about being embarrassed in front of all the ministers.
Then, let's get started.
Roland took Anna's hand and took her to the transmitter.
Uh...Roland?
This is the crystallization of the engineering department, and of course you are the first tester.He blinked at the other party.
Although it has been known in advance that she confirmed the feasibility of communication during the debugging process, what will be recorded in history must be the next formal experiment.
There is also a receiving location, who would you like to be the first to experience it?
Barov and others looked at each other and raised their hands one after another and said, Your Majesty, let me do it!
After some competition, the boss managed to emerge from the crowd with his deepest qualifications and became one of the first testers of long-distance telegram communication.
Theoretically, the transmission and reception of telegrams can be completely done by one person, but it is obviously easier to verify the test results at this time. For people who have never seen a radio, the most critical point is how to make them believe that the other end hundreds of kilometers away really received the information transmitted here?
The easiest way is to let the uninformed recipient report information that should only be known to the sender through telegram.
After Roland briefly explained the test method, he blindfolded Barov's eyes.Anna drew three horizontal and two points on a small blackboard, with horizontal and long tones and short tones.
When everyone confirmed it, she pressed the transmitter's key.
Three long and two sections.
The moment the circuit was turned on, bright blue light burst out from the center of the spark gap.
Since the keys are not connected to the buzzer, there is no other movement in the room except this light.
Everyone couldn't help but hold their breath. The arc was so small that it was difficult to see even if they stood outside the house, let alone Yinguang City, which was hundreds of kilometers away.
But Roland couldn't help but get goose bumps.
At that moment, he seemed to feel something passing by his body.
There is no doubt that it is an illusion that under low power, electromagnetic waves will not have any impact on the human body.
But in his mind, everything was clear and identifiable.
The electric fire seems to be fleeting, but the current transmitted is repeatedly oscillating between the inductor and the capacitor, up to tens of millions of times per second. The rapidly changing electric field quickly spreads along the antenna and ground line and spreads out in all directions.
In this quiet world, it is a cry made by humans. No one can hear its sound, but it is louder than any sound in the past.
Even after leaping hundreds of kilometers, the wave still did not disappear and was recorded truthfully by the antenna of Yinguang City.
It was greeted by two receivers.
After an ancient powder detector captured electromagnetic waves, the metal powder in the glass tube turned loose to condense, which caused the resistance in the circuit to suddenly decrease, and the originally extinguished light bulb burst out with a soft yellow light.
Its biggest function is to inform the monitor that the cry echoes over the dome.
The other one is an ore detector.
It does not require any external power supply and is always in the answering state. A piece of galena and the inserted wire form a natural semiconductor-like semiconductor. The energy radiated by electromagnetic waves forms a faint current inside it. You must wear a headphone to hear the sound.
Without beep modulation, it does not make a crisp and pleasant ticking sound, but it still accurately reproduces the frequency at the time of transmission.
Then reverse the process.
Distance is no longer a problem. It is as fast as it is, or it is light itself.
Anna put down the keys after repeating three times.
According to the agreement, if Yinguang City receives the messaging here, it will send an exact same message.
If it is a regular way to send letters, it will take about five to seven days to complete a round trip between the two places. If it is a flight messenger, it will take at least one day.
But the moment Anna put down the keys, the light on the receiver lit up.
It only takes a few seconds!
There was a commotion in the crowd.
Barov, blindfolded, knew nothing about this. He listened for a long time and finally slowly wrote down the message he heard on the paper.
When he took off his headphones and eye mask, he no longer needed to ask about the test results. The answer was self-evident from the surprise eyes that were revealed by everyone.
The mark on the paper is exactly three horizontal and two dots!
