The next afternoon.
Although the weather was a bit unfavorable.
The light snow from last night had already turned into a heavy snowfall.
Whoosh —!
But it was nothing to Elvin. He just waved his hand gently, and like an eraser, he wiped away the lead clouds that covered half of the duchy.
Except for Anita and Levina.
He also led the wizards from the Tree of Life School, the Mechanical Immortality School, the witches, and the engineering students and professors from Garrett National University to gather on a small hill in Long Island.
However, it was not until the evening, the scheduled test time.
A group of [Electrical Engineers], who had graduated from Garriott National University, finally completed the final adjustment of the signal transmission equipment in the Far Sail Collar. They were sweating profusely as they sent out a signal indicating that they were ready.
Elvin watched the whole process and did not intervene.
In order to continue to replicate the trend of the Electrical Age in the future, it was tolerable to sacrifice a little time to train the soldiers.
"Radio technology" was the technology of transmitting signals through radio waves. The principle was that the change of the current in the conductor would generate radio waves.
Using this phenomenon, information could be loaded into radio waves through modulation technology.
When the radio waves propagated through space and reached the receiver, the electromagnetic field changes caused by the radio waves would generate current in the conductor. Then, through demodulation technology, the information was extracted from the current changes, and the purpose of information transmission was achieved.
This was an extremely practical and important branch of electricity. Elvin, who came from the Information Age, knew the hidden power behind it!
Dong!
Then, Elvin took out an exquisite wooden box the size of a suitcase. It seemed to be made of brass and walnut wood and placed it on the ground. This was an enlarged version of a … radio.
Radio wavelengths could be divided into: long wave, medium wave, short wave, ultra-short wave, and microwave.
Elvin used the short-wave broadcast mode of the AM system.
Due to the existence of the "ionosphere" in the planet's atmosphere.
It could be like a mirror, refracting radio waves that were emitted at the speed of light back to the surface, instead of going straight into space. It also allowed radio stations that were extremely far away to communicate with each other.
On the other hand, the frequency band of "short waves" could be reflected more stably by the ionosphere in the atmosphere.
Furthermore, shortwave waves have strong penetrating power and are not easily interfered with. After the signal is reflected by the ionosphere, it can be transmitted hundreds or even thousands of kilometers away.
Therefore, shortwave broadcasting is suitable for long-distance broadcasting, and can even be used for international broadcasting. It has extremely high strategic value.
Even Elvin's space-time was generally recognized by engineers as the most effective way to transmit information on a large scale around the world. It was safe, cheap, and fast.
However, shortwave broadcasts were mainly transmitted by "sky waves." Affected by atmospheric conditions, the transmission distance at night was much further than during the day.
Since it was the first test, of course, he had to create the most convenient conditions.
When he turned on the radio, there was only a low electronic sound.
Elvin glanced at the time and spoke softly through the [Mental Network].
"Hersey, the test begins."
At the same time.
On the top floor of the Orange Leaf Castle of the Aimor Family in the Far Sail Territory in the south, a black piano that looked expensive was placed next to the towering signal transmission tower and the special sound receiver.
Nympho and Olivia, who were wearing the same off-shoulder evening gown, were already sitting side by side next to the piano with their slender necks and slender arms exposed.
They looked at each other and raised their slender hands at the same time to gently press on the black and white keys made of ivory.
Dong —!
In the eyes of Elvin, who was in Long Island, a radio wave broke through the air, and then the moving piano melody came from the radio.
Di di dong dong …
It was like a pool of cool moonlight, quietly flowing in the forest.
It was the third song of the Begamore Suite, "Moonlight" by the music master Achille Claude.
In fact, when the first note sounded, it meant that the first radio broadcast test in human history had been successful.
However, the wizards, students, and technicians in the field seemed to have forgotten the original intention of this trip, including his sister and Levina. They closed their eyes slightly and were intoxicated by the beautiful music.
A picture of silence and moonlight slowly unfolded in everyone's mind. There was a picture in the song, and a song in the picture. The song was the flowing time and space, and the picture was the frozen moment.
Nympho and Olivia were born in noble families before their marriage. Their artistic attainment was impeccable, and it really raised the overall artistic level of the Garriott Family.
Well, if they had any.
At this time.
Even though there were thousands of kilometers between the two sides, the audience seemed to be sitting by the same piano, holding their breath and listening quietly, afraid to disturb their performance.
They were so immersed in the play that they completely forgot to applaud.
This was probably the charm of the combination of art and the radio. The combination of the two produced a qualitative change.
Even Elvin, who was reliving it, was a little intoxicated.
Although there were many witchcraft tools more magical than the radio, this thing was a technological creation that could be infinitely replicated using basic materials such as brass, steel, wood, and so on.
The most terrifying thing was not the radio itself, but the scale effect behind it.
The grand scene of the whole village carrying a stool and surrounding a box on the threshing floor seemed to appear in front of Elvin's eyes again.
Then, they scrambled to accept their own values and determined to become loyal supporters of the [King's Power].
Compared to this, theaters, newspapers, music halls, bards … with all kinds of inherent flaws, were not even worthy of carrying shoes.
In addition.
There were no obstacles in the technical prerequisites.
If the short-wave was replaced with microwaves, and with the help of the [Mental Network]'s seagulls as a relay station, the signal strength could be rapidly increased and turned into an ultra-long-range high-quality military signal.
The song ended, and the beautiful sound of the piano still lingered in the night sky.
Clap! Clap! Clap!
When they came back to their senses, the tide of applause had already drowned the hillside, and Nympho and Olivia walked out of the air hand in hand on a light butterfly.
Levina was the most excited.
The series of subversive activities in the Lowland Republic was enough to prove:
The "media" played a key role in the shaping of the country's soft power and international power as a medium to spread information and influence. It was better to say it well than to do it well.
The "right to say" was truth, knowledge, and power!
The influence of a new media like the "radio broadcast" was definitely comparable to several "Gods of Music and Opera"!
At this moment.
Whoosh! Whoosh! Whoosh! Whoosh!
Four streams of light suddenly streaked across the sky.
Angel's excited voice sounded in Elvin's heart:
"Teacher, I think you'd better come and see this!"
