Chapter 869 Radio broadcast and return

the next afternoon.

Although the sky is a bit ugly.

The sporadic light snowfall last night has turned into heavy snowfall.

call--!

But this was nothing to Aiwen, he just waved his hand lightly, like an eraser, and wiped away all the lead clouds covering the small half of the principality above his head.

Except for Anita and Rivina.

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

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

A group of [electrical engineers] who have graduated from Garrett National University's engineering department finally completed the final adjustment of the signal transmitting equipment located in Yuanfanling, and sent a signal that it was ready to complete.

Ai Wen watched the whole process without intervening.

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

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

Taking advantage of this phenomenon, information can be loaded onto radio waves through modulation techniques.

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

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

Boom!

Then Ivan took out a suitcase-sized exquisite wooden box that seemed to be made of brass and walnut and put it on the ground. This is an enlarged version of the radio.

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

Based on the nature of their respective frequency bands, Aiwen adopted the short-wave broadcasting mode of the AM system.

Due to the existence of "ionosphere" in the planet's atmosphere.

Like a mirror, it can refract the radio waves emitted at the speed of light back to the surface of the earth without going straight to space, and it also enables radio stations at extremely long distances to communicate with each other.

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

Moreover, the short wave has strong penetrating power and is not easily disturbed. After the signal is reflected by the ionosphere, it can spread hundreds or even thousands of kilometers away.

Therefore, short-wave broadcasting is suitable for broadcasting in distant areas, and can even be used as international broadcasting, which has extremely high strategic value.

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

However, short-wave broadcasting is mainly based on "sky wave" propagation. Due to the influence of atmospheric conditions, the propagation distance at night is much longer than that during the day.

Since this is the first test, of course the most convenient conditions must be created.

Turn on the knob of the radio, there is only a low electronic sound inside.

Aiwen glanced at the time, and said softly through [Soul Network]:

"Hessie, the test begins."

at the same time.

Located on the top floor of the Orange Leaf Fort owned by the Aymore family in Yuanfanling in the South, next to the towering signal transmission tower and the special radio device, there is already a black piano that looks expensive.

Nymph and Olivia, mother and daughter, who were wearing the same one-shoulder evening dress that looked like a dark night and starry sky, showing their slender necks and slender arms, were already sitting shoulder to shoulder 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 Ivan who was on Long Island, a radio wave pierced through the air, and then a moving piano melody sounded on the radio.

beep beep

It seems to be a stream of moonlight that is as cool as water, flowing quietly among the mountains and forests.

That is the third piece of "Bergamo Suite" by music master Archille Claude - "Moonlight".

In fact, when the first note sounded, it meant that the first radio broadcast test in human history had been successful.

However, whether it was wizards, students, or technicians present, they seemed to have forgotten the original intention of the trip, including sister and Rivina, who closed their eyes slightly, intoxicated by the wonderful music.

A picture of silence and moonlight washing slowly unfolded in everyone's hearts. There are paintings in the music, and music in the paintings. The music is the flowing time and space, and the painting is the frozen instant.

Both Ningfu and Olivia were worthy of being the eldest daughters of a 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.

at this time.

Even though the distance between the two parties was thousands of kilometers, the audience seemed to be sitting by the same piano, holding their breath and listening quietly, for fear of disturbing their performance.

It was so engrossing that people forgot to even applaud.

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

Even Ivan, who was revisited, was a little intoxicated.

Although there are many magical props that are 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 most terrifying thing is not the radio itself, but the scale effect behind it.

All the people in the village, old and young, were carrying Maza, and the grand occasion of surrounding a box on the threshing floor seemed to appear before Ai Wen's eyes again.

Then scrambling to accept the indoctrination of their own values, determined to become a loyal supporter of [Royal Power].

Compare that with theatres, newspapers, music halls, bards...with all their inherent flaws.

in addition.

There are no obstacles to the technology front-end.

If the short wave is replaced by microwave, and then the seagulls of [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].

At the end of the song, the wonderful lingering sound of the piano is still echoing in the night sky.

Snapped! Snapped! Snapped!

After regaining consciousness, the tide of applause had already submerged the small hillside, as well as Nymph and Olivia who came out of the air hand in hand on the light quality butterfly.

Among them, Riwena was the most excited.

A series of subversive activities in the Low Countries has sufficed to prove that:

As a medium for disseminating information and a channel for exerting influence, "media" plays a key role in the shaping of national soft power and international power.

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

Politicians in a democratic system are all experts who are used to turning black and white, and who specialize in retreat and never pragmatism.

The influence of the birth of "radio broadcasting" as a new media is definitely on top of several "Gods of Music and Opera"!

At this moment.

call out! call out! call out! call out!

But four streamers of light suddenly crossed the sky.

An Qi's excited voice sounded in Aiwen's heart:

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