Chapter 1347 Newborn Cry

"Really?" Roland couldn't help but feel happy. From Barov's tone, it was clear that it was more than just the facility being built. "Did you hear the signal tone too?"

The so-called iron tower project is the first step in the radio communication plan - in order to meet the huge antennas required for long waves, the Ministry of Construction has erected nearly fifty-meter-high transceiver towers in Beipo Mountain and Silver City. More than half of the towers are only as thick as a human body, so they look like a long, thin needle when viewed from a distance. Coupled with the retractable hydrogen balloon towing the metal wire, the antenna length can reach up to more than 100 meters.

In terms of construction difficulty alone, it doesn’t have much to commend it, but the communication tower is a systematic project, and the transceiver equipment located under the tower is the focus. Since electromagnetic waves are bound to be emitted multiple times during the debugging process, even if they are messy signals, it is normal for them to be captured by the other side in this world without any interference.

"Exactly, Your Majesty." Barov replied excitedly, "It does have some kind of wonderful reaction spontaneously as you said. But... I don't know if it is caused by Silver Light City. .”

"I think this question will be answered soon." Roland pondered for a moment, "Inform the ministers of the Executive Office to go together - they should not want to miss this opportunity to witness history."

…

After several years of development, Beipo Mountain is no longer the original steep mining area with only a few narrow mountain roads. Wide cement roads and railway tracks are built along the slope. 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, with low eaves covered with a row of icicles. They look far less impressive than the new factories on the south bank of the Chishui River. In terms of appearance alone, it is difficult for anyone to associate it with the "new era".

Entering the house, Anna was instructing several sand people from the original Oddities Club to make final preparations. When she saw Roland, she secretly made a gesture of "everything is OK", and then got back to work seriously.

Roland couldn't help grinning.

As early as when the radio plan was finalized, the matter aroused heated discussions in the Executive Office. Most people can clearly realize the changes this project will bring to the human world. If the message can be transmitted, it will be a great enhancement for both the war strength and the control of Neverwinter City.

Wired telephones, flying messengers and listening sigils are proof - under the combined effect of the three, Graycastle's old aristocratic forces have found almost no chance of a comeback. Many officials had believed that centralization would be a long and iterative process. , but the fact is that they have not been able to make any waves since they were overthrown by the First Army. The reason is that in the face of efficient information transmission, the nobles will be annihilated by the Second Army or even the police force as soon as they show any signs of development, leaving no room for brewing and development.

However, the phone has a wire anyway, and the latter two are related to magic power, which the officials can barely understand. But not only does the iron tower project not have any wire connections, but its theoretical effect is even stronger than that of magical creations, which is really incredible. Although there is a basic introduction to electromagnetic waves in elementary education textbooks, learning is learning, but many people still have doubts about this invisible and intangible thing. In a sense, it is even more incredible than a biplane.

Of course, this kind of heated discussion will not affect the actual progress of the project. After all, under Roland's guidance, there have been too many things that can be called miracles in Neverwinter City in these years. Even if he suddenly announced that he would board the Red Moon, The Executive Office will also go all out.

It's just that radio is not his specialty after all, and his control is not as great as that of developing mechanical equipment. This set of transceiver devices is completely copied from the prototype of the Graycastle 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 the ministers.

"Then, let's get started."

Roland took Anna's hand and led her to the transmitter.

"Uh... Roland?"

"This is the product of the Engineering Department. Of course you are the first tester." He winked at the other party. Although it was known in advance that she confirmed the feasibility of communication during the debugging process, what will be recorded in history must be the subsequent formal test.

"There is also a receiving position. Which of you wants to be the first to experience it?"

Barov and others looked at each other, raised their hands and said, "Your Majesty, let me do it!"

After a lot of fighting, the old manager relied on his deepest qualifications to successfully break out of the crowd and became one of the testers of the "first" long-distance telegraph communication.

Theoretically, the transmission and reception of telegrams can be completed by one person, but it is obviously easier to verify the test results when separated at this time. For people who have never seen a radio, the most critical point is how to convince them , did the other end hundreds of kilometers away really receive the information sent here? The simplest way is to have an unsuspecting recipient telegraph information that only the sender should know.

After Roland briefly explained the test method, he asked his bodyguard to blindfold Barov. Anna drew three horizontal lines and two dots on a small blackboard. The horizontal lines represented long sounds and the dots represented short sounds.

When everyone was sure everything was correct, she pressed the transmitter button.

——"Three long and two paragraphs".

The moment the circuit was connected, a bright blue light bloomed in the center of the spark gap.

Since the key was not connected to a buzzer, there was no other movement in the room except this light.

Everyone held their breath involuntarily. This arc of light was so small that it would be difficult to see it even from outside the house, let alone Silver Light City, which was hundreds of kilometers away.

But Roland couldn't help but get goosebumps.

At that moment, he seemed to feel something passing through his body.

There is no doubt that this is an illusion - at low power, electromagnetic waves will not have any effect on the human body. But in his mind, everything formed a clear and discernible picture. The electric fire seems to be fleeting, but the current passed out repeatedly oscillates between the inductor and the capacitor, as many as tens of millions of times per second. The rapidly changing electric field spreads rapidly along the antenna and ground wire, and spreads in all directions. Spread out.

In this silent world, it is a human cry - no one can hear its voice, but it is louder than any voice in the past.

Even after flying hundreds of kilometers, this wave still did not disappear and was faithfully recorded by the antenna of Silver Light City.

It was greeted by two receivers.

After an ancient powder detector captured electromagnetic waves, the metal powder in the glass tube changed from loose to condensed, which caused the resistance in the circuit to suddenly decrease, and the originally extinguished light bulb bloomed with a soft yellow light. Its biggest function is to tell the listener that the cry is echoing above the dome.

The other one is an ore detector. It does not require any external power supply and is always in the listening state. A piece of galena and an inserted wire form a natural semiconductor-like substance. The energy radiated by electromagnetic waves forms a weak current inside it. You must wear headphones to hear the sound.

Without buzz modulation, it doesn't produce a crisp, sweet click, but it still accurately reproduces the frequency at which it was sent.

Then the process is reversed.

Distance is no longer a problem, light is as fast as it is fast, or in other words, it is light itself.

Anna repeated it three times and put down the button.

According to the agreement, if Silver Light City receives the subpoena from here, it will send an identical message. If you use the conventional method of sending letters, it will take about five to seven days to complete a round trip between the two places. If you use a flying courier, it will also take at least one day.

But the moment Anna put down the button, the light on the receiver came on.

It only takes a few seconds!

There was a commotion in the crowd.

The blindfolded Barov knew nothing about this. He listened for a long time and finally slowly wrote down the message he heard on paper.

When he took off his headphones and eye mask, there was no need to ask about the test results - the answer was self-evident from the surprised looks on his face.

The marks on the paper are exactly three horizontal lines and two dots!
