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 heavy snow of goose feathers.
call-!
But for Aiwen, this was nothing, just a light wave of his hand, like an eraser, which had completely wiped the cloud of lead that covered the small half of the principality on 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 Calvary, to gather on a small hill in Long Island.
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.
Aiwen watched the whole process without intervening.
In order to continue to replicate and grow the future "trend of the electrical age", 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 techniques.
When the electric wave propagates through space and reaches the receiving end, the electromagnetic field changes caused by the electric wave will generate 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, and 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 wavelengths can be divided into: long wave, medium wave, short wave, ultrashort wave, and microwave.
Aiwen adopted the shortwave broadcasting mode of the AM system.
Because there is an "ionosphere" in the planet's atmosphere.
It can be like a mirror, re-refracting radio waves emitted at the speed of light back to the surface, instead of going straight to space, and also allowing radio stations far away to communicate with each other.
In the "short wave" frequency band, stable reflection can be achieved in the ionosphere in the atmosphere.
Moreover, the 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 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 the most convenient conditions must be created.
Turn on the radio's knob, and there is only a low and low electric tone.
Aiwen glanced at the time, and said softly through [Mind Network]:
"Hessy, 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 Sailing, next to the towering signal transmission tower and special radio equipment, a black piano that seems to be expensive has been placed.
Nymphs and Olivia mothers and daughters, wearing the same one-shoulder evening dress like the starry night sky, with slender necks and slender arms, are already sitting side by side by the piano.
Glancing at each other, he raised his slender hand and lightly tapped on 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.
Beep buzz buzz...
It seems to be a cool moonlight flowing quietly in the mountains and forests.
That was the third song "Moonlight" in the "Bergamo Suite" by the music master Akhil 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 was a wizard, a student, or a technician in the field, it seemed that they had forgotten the original intention of this trip, including their sister and Li Wei Na who closed their eyes slightly and reveled in the wonderful music.
A picture of loneliness 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.
Before their marriage, Nymph and Olivia were both eldest ladies from a noble family, and their artistic qualities were impeccable, which really raised the overall artistic level of the Garriott family.
Well, if they have one.
at this time.
Even though there is a distance of thousands of kilometers between the two sides, 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 somewhat intoxicated.
Although there are many witchcraft props that are more magical than the radio, this thing is a technological creation that can be replicated infinitely using basic materials such as brass, steel, wood, etc.
The most terrifying thing is not the radio itself, but the scale effect behind it.
The whole village, old and young, all carrying horses and surrounded by a box on the threshing floor, seemed to once again appear in front of Aiwen.
Then he rushed to accept his 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 microwave, and the seagulls of [Mind Network] are used as relay stations, the signal strength can be quickly increased, and converted into ultra-long-range high-quality military signals, which can be applied to [all-heavy battleships].
At the end of the song, the beautiful reverberation of the piano still reverberates in the night sky.
Snapped! Snapped! Snapped! ...
After regaining his senses, the tide of applause had obliterated the hillside, as well as the Nymph and Olivia who walked out of the air on the light butterfly hand in hand.
Among them, Li Wei Na is the most excited.
A series of subversive activities in the Low Countries have been enough to prove:
"Media" serves as a medium for disseminating information and a communication channel for exerting influence. Uukanshu.com plays a key role in the shaping of national soft power and international power. No matter how good it is, it is really not as good as it is said.
The "right to speak" is truth, knowledge and power!
And the politicians under the democratic system are all experts who are used to turning black and white, and are never pragmatic.
The influence of the birth of the new media of "radio broadcasting" is absolutely topped by several "gods of music and opera"!
At this moment.
call out! call out! call out! call out!
But four streamers suddenly crossed the horizon.
An Qi's excited voice followed in Irving's heart:
"Teacher, guess what we brought back? I think you'd better take a look at this!"
