Chapter 869 Radio and Return

second day afternoon.

Although Tiangong is not beautiful.

Last night’s sporadic snowflakes have turned into big snowflakes.

Wow—!

But it didn’t matter to Alwin, he just waved his hand lightly, like a board eraser, and wiped away the cloud of lead that covered half of the dukedom above his head.

Except Anita and Levina.

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

However, until near evening, the scheduled test time.

A group of [Electrical Engineers] who have graduated from Garriott National University Engineering finally completed the final debugging of the signal transmitting equipment located in Yuanfan collar, brow beaded with sweat, and sent the ready signal. .

Alwin stayed on the sidelines throughout.

In order to continue to replicate and expand the “electric age trend” in the future, it is still tolerable to temporarily sacrifice a little time for training.

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

Utilizing this phenomenon, modulation techniques can be used to load information into radio waves.

When the radio wave propagates through space and reaches the receiving end, the electromagnetic field change caused by the radio wave will generate 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 electric power, and Alwin from the information age knows the hidden power behind it!

dong!

Then Alwin took out a suitcase-sized wooden box that seemed to be made of brass and walnut and placed it on the ground. This was an enlarged version. .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, Alwin adopts AM modulation shortwave broadcasting mode.

Because of the existence of the “ionosphere” in the planet’s atmosphere.

It can refract radio waves emitted at the speed of light back to the surface like a mirror, instead of going straight to space, and it also enables radio stations to communicate with each other at great distances.

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

In addition, the shortwave has strong penetrating power and is not easy to be interfered. After the signal is reflected by the ionosphere, it can propagate to hundreds or even thousands of kilometers away.

Therefore, shortwave broadcasting is suitable for long-distance broadcasting, and can even be used as international broadcasting, which has extremely high strategic value.

Even Alwin’s space-time is widely regarded by engineers as the most effective way to transmit information on a large scale globally, safe, cheap and fast.

However, shortwave broadcasting is mainly based on “sky wave” transmission, and affected by atmospheric conditions, the transmission distance at night is much farther than in the daytime.

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

Turn on the knob of the radio, and there is only low-pitched electronic sound.

Alwin glanced at the time and said softly through the [spirit net network]:

“Hessie, the test begins.”

Yu At the same time.

Located on the top floor of the Orange Leaf Castle of the Aymore family in the southern Yuanfan, next to the towering signal tower and the special radio device, a black piano that seems to be expensive has been placed.

Wearing the same dark Ye Xingkong-like one-shoulder evening dress, Nymph and Olivia, mother and daughter with slender necks and slender arms, have sat by the piano side by side .

Glancing at each other, he raised his slender jade hand and tapped lightly on the black and white keys made of ivory.

Boom!

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

DiDi dongdong

It seems like a pool of cool moonlight flowing quietly in the mountains and forests.

That is the third piece of the “Bergamore Suite” by music master Achille Claude – “Moonlight”.

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

However, whether the wizard, students, or technicians in the room seemed to have forgotten the original intention of this trip, including elder sister and Liweina, all closed their eyes slightly and reveled in the wonderful music .

A picture full of silence and moonlight slowly unfolded in the hearts of everyone. There are paintings in the songs, and there are songs in the paintings. The songs are the flowing time and space, and the paintings are the frozen moments.

Nymph and Olivia were born as Eldest Young Lady of a noble family before their marriage, and their artistic quality was impeccable. It was fiercely that raised the overall artistic level of the Garriott family.

Well, if they had.

At this time.

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

It was so immersive that people even forgot to applaud.

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

Even Alwin, who was reliving it, was a little intoxicated.

Although there are many witchcraft props that are more magical than the radio, 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.

The grand occasion of the whole village, old and young, carrying their horses and surrounding a box on the threshing floor, seemed to reappear in front of Alwin’s eyes.

And then scrambling to accept the indoctrination of their own values, determined to become a loyal supporter of [Kingdom].

By contrast, theaters, newspapers, concert halls, bards, with all their inherent flaws, don’t even deserve a shoe.

Additionally.

Technical prerequisites are completely free of obstacles.

If the short wave is replaced by microwave, and then the seagulls of the [spirit net network] are used as relay stations, the signal strength can be quickly improved, and the signal can be converted into ultra-long-range high-quality military signals, which can be applied to [full-heavy battleships]. 】Go up.

The song ended, and the wonderful reverberations of the piano still echoed in the night sky.

pa! pa! pa!

After came back to his senses, the tidal wave of applause had drowned out this hillside, and the light butterflies were swept from the air hand in hand Nymph and Olivia coming out.

Among them, Li Weena was the most excited.

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

As a medium for disseminating information and a channel for exerting influence, the “media” plays an important role in the shaping of national soft power and international power. As a key role, no matter how well you do it, it is better to say it well.

“Speak” is truth, knowledge and power!

The politicians under the Democratic System are all experts who are accustomed to confounding black and white, and who are dedicated to retreat and never be pragmatic.

The influence of the birth of a new media such as “radio broadcasting” is absolutely topped by several “Gods of Music and Opera”!

Right now.

xiu! xiu! xiu!

There are four streams of light suddenly across the horizon.

Angie followed with an excited voice in Alwin’s heart:

“Teacher, guess what we brought back? I think you’d better take a look at this! ”

Thanks to the book friend Gusu stray cats for the two hundred rewards! Thank you for your monthly and recommended tickets!
