Release that Witch - Chapter 1387

[Chapter 1347]

“Really?” Roland couldn’t help being overjoyed. Judging from Barov’s tone, it was clear that it was not just as simple as the completion of the facilities. “You also heard the signal tone?”

The so-called iron tower project was the first step in the radio communication plan—in order to meet the huge antennas required by long waves, the Ministry of Construction erected nearly 50-meter-high transceiver towers in Beipo Mountain and Yinguang City.

More than half of the tower body is only as thick as a human body, so it looks like a long, thin needle from a distance.

Coupled with the retractable hydrogen balloon dragging the metal wire, the antenna length can reach more than 100 meters at most.

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 key point.

Since electromagnetic waves will inevitably be emitted many times during the debugging process, even if it is a messy signal, in this world without any interference, it is normal to be captured by the other side.

“Exactly, Your Majesty.” Barov replied excitedly, “It does have some kind of wonderful reaction spontaneously as you said. It’s just… I don’t know if it is caused by the Silver City .”

“I think this question will be answered soon.” Roland pondered for a moment, “Notify the ministers of the administrative department to go together – they probably don’t want to miss this opportunity to witness history.”

…

After several years of development, Beipo Mountain is no longer the precipitous 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 one-story houses, with a row of ice edges hanging on the low eaves, which look far less impressive than those new factory buildings 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”.

Walking into the house, Anna was instructing several sandmen from the original strange objects society to make the final preparations. When she saw Roland, she secretly made a gesture of “everything is in order”, and then went back to work in a serious manner.

Roland couldn’t help grinning.

As early as when the radio plan was finalized, the matter sparked heated discussions in the administration hall.

Most people can clearly realize what kind of changes the project will bring to the human world.

If the news can be delivered, it will be a great enhancement in terms of both the strength of the war and the control of Neverwinter.

Wired telephones, flying couriers, and the Sigil of Hearing are the proof – with all three combined, the old aristocratic forces in Greycastle have hardly found any chance of making a comeback, and many officials had believed that centralization would be a long and iterative process , but the fact is that after they were overthrown by the First Army, they have not been able to make 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 any sign, leaving no room for brewing and development.

But the phone has a wire anyway, and the latter two are related to magic, and the officials can barely understand it.

But not only does the iron tower project not have any line connections, but the theoretical effect is even stronger than the magical creation, which really makes people feel a little incredible.

Although there is a basic introduction to electromagnetic waves in elementary education textbooks, learning is nothing but learning. Many people still have doubts about this invisible and intangible thing.

In a sense, it is even more unimaginable than a biplane.

Of course, this hot discussion will not affect the actual progress of the project. After all, under the guidance of Roland, there are so many things that can be called miracles in Neverwinter these years. Even if he suddenly announced that he would go to the Red Moon, The Executive Office will also go all out.

It’s just that radio is not his specialty after all, and he doesn’t have as much confidence in researching and developing mechanical equipment. This set of transceiver devices is also completely reproduced 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 losing face in front of the ministers.

“Then, let’s begin.”

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

“Uh…Roland?”

“This is the crystallization of the engineering department. Of course you are the first tester.” He winked at the other party and said.

Although she knew in advance that she confirmed the feasibility of communication during the debugging process, what will be recorded in history must be the next official test.

“There is also a receiving position, who of you wants to be the first to experience it?”

Barov and the others looked at each other, raised their hands and said, “Your Majesty, let me come!”

After some scrambling, the old manager relied on his deepest qualifications to successfully break out from 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 those who have never seen radio, the most critical point is how to convince them , The other end hundreds of kilometers away really received the information sent here?

The easiest way is to let the uninformed receiver report information that should only be known to the sender by telegram.

After Roland briefly explained the test method, he asked the guards to cover Barov’s eyes.

Anna drew three horizontal lines and two dots on a small blackboard. The horizontal lines represent long sounds and the dots represent short sounds.

After everyone confirmed it was correct, she pressed the button on the transmitter.

——”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 the buzzer, apart from this light, there was no other movement in the room.

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

But Roland couldn’t help but get goosebumps.

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

There is no doubt that it is an illusion – in the case of low power, electromagnetic waves will not have any effect on the human body.

But in his mind, everything became a clear and recognizable picture.

The electric fire seems to be fleeting, but the transmitted current repeatedly oscillates between the inductor and the capacitor, tens of millions of times per second, and 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 cry of human beings – no one can hear it, but it is louder than any sound in the past.

Even after flying hundreds of kilometers, this wave still did not disappear, and was 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 drop suddenly, and the light bulb that was originally extinguished released a soft yellow light.

Its greatest function is to inform listeners that the cry is echoing over the dome.

The other is an ore detector.

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

In the absence of beep modulation, it doesn’t produce a crisp and melodious click, but it still accurately reproduces the frequency when it was sent.

The next step is to reverse the process.

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

Anna put down the key after repeating it three times.

According to the agreement, if Silver Light City receives the summons from here, it will send the exact same message.

If it is a conventional way of sending letters, it takes about five to seven days to complete a round trip between the two places, and it takes at least one day to switch to a flying courier.

But the moment Anna put down the key, the light on the receiver turned on.

It was only a few seconds before and after!

There was a commotion in the crowd.

The blindfolded Barov didn’t know anything about it. He listened for a long time, and finally wrote down the message he heard on the paper slowly.

When he took off the earphones and eye mask, there was no need to ask about the test results—the answer was self-evident from the surprised eyes of everyone.

The mark on the paper is exactly three horizontal lines and two dots!
