The next afternoon.

Although God is a little unkind.

The scattered light snow last night has turned into a heavy snowfall.

call--!

But for Ivan, this was nothing. He just waved his hand gently, like an eraser, and wiped away all the lead clouds above his head that covered half of the principality.

Except Anita and Levina.

He also led a group of wizards in the principality, including the "Tree of Life School", "Mechanical Immortality School", witches, as well as engineering students and professors from Garriott National University, to gather on a hillside on Long Island.

However, it was not until near evening that the scheduled test time was reached.

A group of [electrical engineers] who had graduated from the Engineering Department of Garriott National University finally completed the final debugging of the signal transmitting equipment located at the far sail collar with sweating profusely, and sent the signal that it was ready to be completed.

Alvin watched the whole process without interfering.

In order to continue to replicate and grow in the future "electrical era 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 a conductor generate radio waves.

Taking advantage of this phenomenon, information can be loaded into radio waves through modulation technology.

When the radio wave propagates through space and reaches the receiving end, the change in the electromagnetic field caused by the radio wave will generate a current in the conductor. Then the information is extracted from the change in the current through demodulation technology, and the purpose of information transmission is achieved.

This is an extremely practical and important branch of electricity, and Ivan, who comes from the information age, is well aware of the power hidden behind it!

Boom!

Then Alvin took out a suitcase-sized, seemingly exquisite wooden box made of brass and walnut and placed it on the ground. This was an amplified version of... a radio.

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

Based on the nature of their respective frequency bands, Aiwen adopted the shortwave broadcast mode of amplitude modulation.

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

It can be like a mirror, refracting radio waves emitted at the speed of light back to the earth's surface without going straight into space. It also allows extremely distant radio stations to communicate with each other.

In the "short wave" frequency band, stable reflection can be achieved in the ionosphere in the atmosphere.

Moreover, shortwave has strong penetrating power and is not susceptible to interference. After the signal is reflected by the ionosphere, it can propagate hundreds or even thousands of kilometers away.

Therefore, shortwave broadcasting is suitable for remote area broadcasting and can even be used for international broadcasting, which has extremely high strategic value.

Even Ivan's space-time is generally considered by engineers to be the most effective way to transmit information globally on a large scale, safe, cheap and fast.

However, shortwave broadcasts are mainly propagated by "sky waves". Affected by atmospheric conditions, the propagation distance at night is much farther than during the day.

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

Turning on the knob of the radio, there was only low electronic music.

Ai Wen glanced at the time and said softly through the [Psychic Network]:

"Hersey, the test begins."

At the same time.

Located on the top floor of the Orange Leaf Castle of the Elmore family in the Southern Far Sail Leader, next to the towering signal transmission tower and the unique radio device, a black piano that looks expensive has been placed.

Mother and daughter Nymph and Olivia, wearing the same one-shoulder evening gown that looked like a dark night sky, revealing their long necks and slender arms, were already sitting side by side at the piano.

They looked at each other and at the same time raised their slender hands and tapped lightly on the black and white keys made of ivory.

Boom——!

In the eyes of Alvin, who was on Long Island, a radio wave broke through the sky, and then a moving piano melody sounded on the radio.

beep dong dong...

It is like a stream of cool moonlight flowing quietly in the mountains and forests.

That was the third piece of the "Bergamo Suite" by the music master Achille Claude - "Moonlight".

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

However, everyone present, including wizards, students, and technicians, seemed to have forgotten the original intention of the trip, including my sister and Levina, who closed their eyes slightly and were intoxicated by the beautiful music.

A picture of complete silence and the wash of moonlight slowly unfolded in everyone's hearts. There is a painting in the music, and there is a music in the painting. The music is the flowing time and space, and the painting is a solidified momentary scene.

Nymph and Olivia were worthy of being the eldest ladies of a noble family before they got married. Their artistic qualities were impeccable, which really raised the overall artistic level of the Garriott family.

Well, if they had.

at this time.

Even though there were thousands of kilometers between the two sides, the audience seemed to be sitting at the piano, holding their breath and listening quietly, for fear of disturbing their performance.

It was so immersive that people completely forgot to even applaud.

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

Even Alvin, who was reliving it, was a little intoxicated by it.

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

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

The grand scene of the whole village, old and young, carrying matzha and surrounding a box on the threshing floor, seemed to appear before Ivan's eyes again.

Then they rushed to accept the indoctrination of their own values ​​and determined to become a loyal supporter of [Royal Power].

In comparison, theaters, newspapers, concert halls, minstrelsy... all have inherent flaws and are not even worthy of carrying shoes.

in addition.

There are no obstacles in terms of technology.

If the shortwave is replaced by microwave, and the seagulls of the [Psychic Network] are used as relay stations, the signal strength can be quickly increased, converted into an ultra-long-range high-quality military signal, and applied to the [Full Heavy Battleship].

The song ended, and the beautiful sound of the piano still lingered in the night sky.

Bang! Bang! Bang!...

After coming back to his senses, the tide of applause had already annihilated the hillside, as well as Nymph and Olivia walking hand in hand from the air on the light butterfly.

Among them, Levina was the most excited.

A series of subversive activities in the Low Countries are enough to prove:

As a medium for disseminating information and a communication channel for exerting influence, "media" plays a key role in shaping national soft power and international power. No matter how well it is done, it is really not as good as what it says well.

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

Politicians in a democratic system are all experts who are accustomed to confusing right and wrong, and are exclusively pragmatic and never pragmatic.

The influence of the birth of a new media like "radio broadcasting" is definitely greater than that of several "gods of music and opera"!

At this moment.

Phew! Phew! Phew! Phew!

But four streaks of light suddenly crossed the horizon.

An Qi's excited voice then sounded in Alvin's heart:
Chapter completed!
