Extraordinary Voyage Chapter 869: Radio broadcast and return

The next afternoon.

Although Tiangong is a bit unbeautiful.

The sporadic light snow last night has turned into a fluttering heavy snow.

Huh--!

But for Aiwen, this is nothing. He just waved his hand gently, like an eraser, and had wiped out all the plumes that covered the small half of the principality above his head.

Except for Anita and Livina.

He also led a group of wizards in the Principality, including the "Tree of Life School", "Mechanical Immortal School", and witches, as well as the engineering students and professors of the National University of Galliot. on the hill.

However, until near the evening, the scheduled test time.

A group of [Electrical Engineers] who have graduated from the National University of Galliot’s Engineering Department, finally completed the final commissioning of the signal transmitter equipment located in Yuanfanling and sent a signal for completion.

Ivan watched the whole process without intervening.

In order to continue to replicate and grow the future "electric age trend", it is still tolerable to temporarily sacrifice a little time for military training.

"Radio technology" is a technology that transmits signals through radio waves. The principle is that changes in the strength of the current in the conductor will generate radio waves.

Using this phenomenon, information can be loaded into radio waves through modulation technology.

When the electric wave propagates through space and reaches the receiving end, the change in the electromagnetic field caused by the electric wave will generate an electric current in the conductor. Then the demodulation technology is used to extract the information from the current changes to achieve the purpose of information transmission.

This is an extremely practical and extremely important branch of electric power. Aiwen from the information age knows the hidden power behind it!

Boom!

Then Ivan took out a suitcase the size of a suitcase, which seemed to be an exquisite wooden box made of brass and walnut, and placed it on the ground. This was an enlarged version...radio.

Radio wavelength can be divided into: long wave, medium wave, short wave, ultra short wave, microwave.

Ivan adopted the shortwave broadcasting mode of the AM system.

Because there is an "ionosphere" in the planet's atmosphere.

It can resemble a mirror, refracting the radio waves emitted at the speed of light back to the surface, instead of going straight to space, and also allowing stations that are far away to communicate with each other.

The "short wave" frequency band can achieve stable reflection in the ionosphere in the atmosphere.

Moreover, short-wave penetration is strong and it is not easy to be interfered. After the signal is reflected by the ionosphere, it can travel hundreds or even thousands of kilometers away.

Therefore, shortwave broadcasting is suitable for broadcasting in far areas, and can even be used as international broadcasting, which has extremely high strategic value.

Even the time and space of Aiwen is generally regarded by engineers as the most effective way to transmit information on a large scale worldwide, which is safe, cheap and fast.

However, shortwave broadcasting is mainly based on "sky wave" propagation. Affected by atmospheric conditions, the propagation distance at night is much longer than during the day.

Since it is the first test, of course, we must create the most convenient conditions.

Turn on the **** of the radio, and there is only a low electric tone inside.

Ivan glanced at the time, and said softly through [Spirit Network]:

"Hessie, the test begins."

At the same time.

Located on the top floor of the Orange Leaf Fort of the Emore family in the Southern Far Sails, next to the towering signal transmission tower and special radio equipment, there has been a black piano that seems to be expensive to build.

The mother and daughter of Nymph and Olivia, who wore the same one-shoulder evening dress like a dark night starry sky, with slender necks and slender arms, were already sitting side by side by the piano.

Looking at each other, he raised his slender hand and lightly tapped the black and white key made of ivory.

Boom——!

In the eyes of Irvine on Long Island, a radio wave broke through the air, and then a moving piano melody sounded on the radio.

嘀嘀咚咚...

It seems to be a cool moonlight flowing quietly among the mountains and forests.

That was the third song of "Bergamo Suite"-"Moonlight" by the music master Asil Crowder.

In fact, when the first note is sounded, it means that the first radio broadcast test in human history has been successful.

However, whether it is a wizard, a student, or a technician in the scene, it seems that they have forgotten the original intention of this trip, including their sister and Li Wei Na, who closed their eyes slightly and reveled in the beautiful music.

A picture of silence and moonlight slowly unfolded in everyone's hearts. There are paintings in the tunes, tunes in the paintings, tunes are flowing time and space, and paintings are instantaneous scenes that are frozen.

Nymph and Olivia were both eldest ladies from the noble family before their marriage, and their artistic accomplishments were impeccable, which really raised the overall artistic level of the Garriott family.

Well, if they have one.

At this time.

Even if there is a distance of thousands of kilometers between the two parties, the audience seems to be sitting at the same piano, holding their breath and listening quietly, for fear of disturbing their performance.

It's so overwhelming that people forget even the applause.

This is probably the charm of the superposition of art and radio, and the fusion of the two has produced a qualitative change.

Even the relived Aiwen was a bit intoxicated.

Although there are many magic items that are more magical than radios, this thing is a technological creation that can be replicated infinitely using basic materials such as brass, steel, wood, and so on.

The most terrifying thing is not the radio itself, but the scale effect behind it.

The grand occasion of all the old and young in the village carrying horses and surrounding a box on the threshing floor seemed to once again appear in front of Aiwen.

Then scrambled to accept their own values ​​and determined to become a loyal supporter of [king power].

In contrast, theaters, newspapers, concert halls, minstrels with various inherent flaws... are not even worthy of shoes.

In addition.

There are no obstacles to the technology front.

If the short wave is replaced by a microwave, and the seagulls of the [Mind Network] are used as relay stations, the signal strength can be quickly increased and converted into an ultra-long-range high-quality military signal, which can be applied to the [full-heavy battleship].

At the end of the song, the beautiful reverberation of the piano still reverberates in the night sky.

Slap! Snapped! Snapped! ...

After regaining consciousness, the wave of applause has obliterated the hillside, and the Nymph and Olivia who walked out of the air on the light butterfly hand in hand.

Levina is the most excited among them.

A series of subversive activities in the Low Countries are sufficient proof:

"Media" as a medium for disseminating information and a communication channel for exerting influence~IndoMTL.com~ plays a key role in the shaping of national soft power and international power.

The "right to speak" is truth, knowledge and power!

The politicians under the democratic system are all experts who are accustomed to turning black and white, and are never pragmatic.

The influence of the birth of the new media, "Radio Broadcasting", is absolutely topped by several "Gods of Music and Opera"!

At this moment.

Shoo! call out! call out! call out!

Four streams of light suddenly crossed the horizon.

An Qi followed with an excited voice in Irvine's heart:

"Teacher, guess what we brought back? I think you'd better take a look at this!"
