Release that Witch

“Is it?” Roland couldn’t help but listen to Barov’s tone. It’s not just that the facility was built. “Do you hear the signal?”

The so-called iron tower project is the first step of the radio communication plan. In order to meet the huge antenna needed for long wave, Ministry of Construction has set up a transceiver tower nearly 50 meters high in Northern Slope Mountain and Silver Light City. Fiction. More than half of the towers are only adult body thickness, so looking from a distance is like a sharp long needle. Together with the retractable hot air balloon, the antenna length can reach more than 100 meters.

In terms of construction difficulty, it does not have much to be commended, but the communication tower is a system engineering, and the transceiver equipment located under the high tower is the focus. Since the electromagnetic wave is inevitably emitted multiple 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.

“Exactly, Your Majesty.” Barov replied excitedly. “It does have some kind of wonderful reaction spontaneously like you said. Just… I don’t know if it was caused by Silver Light City. ”

“I think this question will be answered very quickly.” Roland indulged for a moment, “Notifying the Ministers of the Executive Office to go with them. They should not want to miss this opportunity to witness the history.”

……

After years of development, the Northern Slope Mountain is no longer the first steeping site with only a few narrow mountain roads. The wide concrete roads and railroad tracks are built along the slope. It takes only a quarter of an hour to get to the top of the mountain by train.

Not far from the tower, there is a row of plain red brick bungalows. The low eaves are covered with a row of ice ribs that look far less than the new factory buildings on the south bank of the Scarlet Water 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 Sandpeople from the original Wonder Objects Society to do the final preparations. When she saw Roland, she secretly sneaked a gesture of “all right” and then went back to work.

Roland couldn’t help but open his mouth.

As early as the radio plan was set, the matter caused a heated discussion in the Executive Office. Most people are well aware of what changes the project will bring to the human world. If the message can be delivered, it is a great enhancement for both the strength of the war and the control of Neverwinter City.

Wired phones, flight messengers, and Listening Sigil proved that under the combined influence of the three, Greycastle’s old noble forces barely found any chance to make a comeback. Many officials once thought that centralization would be a long-term and iterative process, but the fact is that they After being overthrown by the First Army, it has not been able to pick up any waves. The reason is that in the face of efficient information transmission, the noble just exposed a little bit will be annihilated by the Second Army and even the police force, leaving no room for development.

However, the phone has a good root, and the latter two are related to magic power. Officials can barely understand it. The iron tower project not only does not have any line connections, but the theoretical effect is stronger than the magic power creation, which makes people feel incredible. Although there is a basic introduction to electromagnetic waves in primary school textbooks, you can learn to learn. Many people still have doubts about this invisible and intangible thing. 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 Roland’s guidance, there are too many things in Neverwinter City that can be called miracles in these years, even if he suddenly announced that he would board Red Moon, the administration. The hall will also go all out.

It’s just that the radio is not his specialty. It’s not as big as the R&D machinery. This set of transceivers is completely copied from the prototype of the Greycastle Design Bureau. The actual effect is not clear. With the gesture of Anna, he didn’t have to worry about losing face in front of the ministers.

“So, let’s get started.”

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

“Hey…Roland?”

“This is the crystallization of the engineering department, of course you are the first tester.” He blinked at each other. Although she had known in advance that she confirmed the feasibility of the communication during the commissioning process, it would be recorded in the annals of history and must be the next formal test.

“There is still a receiving location, who do you want to experience the first one?”

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

After some competition, the old Premier Minister, with its deepest qualifications, successfully emerged from the crowd and became one of the “first” long-distance telegraph communication testers.

In theory, the transmission and reception of telegrams can be done by one person, but it is obviously easier to verify the test results at this time. For those who have never seen the radio, the most important point is how to make them believe. The other side of the hundred kilometers away really received the information transmitted here? The easiest way is to let the unsuspecting receiver report the information that should only be known to the sender.

Roland clarified the test method and let the personal guard cast a blind eye on Barov. Anna scored three horizontal and two points on a small blackboard. The horizontal represents the long sound and the dots represent the short sound.

When everyone confirmed it, she pressed the transmitter’s button.

Three long and two paragraphs.

At the moment when the circuit is turned on, a bright blue light blooms in the center of the spark gap.

Since the buzzer is not connected to the electric button, there is no other movement in the room except this light.

Everyone can’t help but breathe. This arc is so small that it is hard to see outside the house, let alone Silver Light City, which is hundreds of kilometers away.

Roland can’t help but raise the goose bumps.

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

There is no doubt that it is an illusion that in the low-power situation, electromagnetic waves will not have any effect on the human body. But in his mind, everything is clearly visible. The electric fire seems to be fleeting, and the current that is transmitted is repeatedly oscillated between the inductor and the capacitor, up to tens of millions of times per second. The rapidly changing electric field is rapidly opened along the antenna and the ground, and is in all directions. Spread out.

In this silent world, it is a human voice that no one can hear it, but it is brighter than any voice in the past.

Even after a few hundred kilometers, the wave still disappeared and was recorded by the Silver Light City antenna.

It is the two receivers that greet it.

After an ancient powder detector captures electromagnetic waves, the metal powder in the glass tube turns from loose to agglomerated, which causes the resistance in the circuit to drop sharply, and the originally extinguished bulb emits a soft yellow light. Its biggest role is to inform the listener that the humming sound is echoing over the dome.

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

In the case of no buzzer modulation, it does not emit a crisp, pleasing treble, but it still accurately reproduces the frequency of transmission.

Then it is to reverse this process.

Distance is no longer a problem, how fast it is, how fast it is, or it is light itself.

Anna repeated the key after repeating it three times.

By convention, Silver Light City will send an identical message if it receives a message here. If it is a regular way of sending a letter, it takes about five to seven days to complete a round trip between the two places, and it takes at least one day to change to a flight messenger.

But the moment the Anna puts down the button, the light from the receiving machine lights up.

Just a few seconds before and after!

There was a stir in the crowd.

Barov, who was blindfolded, knew nothing about it. He listened for a long time and finally wrote down the message he had heard on paper.

When he took off the headphones and the eye mask, there was no need to ask the test results for the surprised eyes that emerged from the crowd. The answer is self-evident.

The mark on the paper is three horizontal and two points!
