Release that Witch - Chapter 1351

[Chapter 1313 “Information Age”]

Graycastle, Neverwinter.

The report on the battle on Grand Duke Island and the situation in Wolfheart was sent to Roland two days later.

Compared with the time it took for a week to send a letter from Evernight City in the north to Neverwinter, this kind of communication speed can not but be said to be a huge improvement.

Whether it is the short-distance express delivery by flying messengers or the long-distance running of steam ships day and night, they are now integrated into a part of the message delivery system. Every important message will be equipped with a special person, a special ship, or even a plane—— This time the report was sent by Tilly.

“Thanks for your hard work.” Roland handed over the Chaos drink warmly, “Is the situation over there okay?”

“Don’t you know after reading the report?” Tilly took the cup and glanced at him, “Being so attentive, what are you guilty of? Is it because I don’t have any clue about my special machine?”

“Pfft…” Nightingale’s suppressed laughter came from behind.

“How come, I have selected the most suitable one from several plans, and as long as Anna finds time, I can start trial production immediately.” Roland said quickly, “As you know, several projects have arrived recently. She is really too busy for the most critical step.”

“For Anna’s sake, I won’t argue with you this time, brother.” Tilly took a sip of the drink, wiped her mouth and walked out of the office, “The Seagull is going back soon, I’ll go back first.” Aerial Knight Academy.”

“Don’t you stay for a day?” He was a little surprised.

“There’s no way, the only ones on the front line that can threaten the Lord of the Vault of Heaven are the Seagull and Andrea, and… I don’t want to miss any opportunity for revenge.” Tilly waved her back to him, “Then I’m leaving, elder brother.”

Looking at the closed door, Nightingale sighed softly, “Everyone…is working hard.”

If possible, I’d rather they work on something other than war.

Roland had such a thought in his heart, but he didn’t say it – because no one can rest this burden until the end of the battle of divine will and the fate of mankind is decided.

Saying this now has no meaning other than evading responsibility.

After a moment of silence, he opened the report seal.

After reading all the reports, Roland finally understood the meaning of Tilly’s words.

Edith Kant and Andrea were undoubtedly the biggest contributors to this battle who were able to issue the retreat order in time and successfully ambushed a devil king who came and went without a trace in the vast sea.

But at the same time, the sender of that key information cannot be ignored – without this person’s desperate action, the subsequent victory would not be possible.

“What are you going to do?” This matter obviously attracted Nightingale’s attention.

“No matter what his original intention for sending this secret letter is, this person’s name and achievements should not be forgotten.” Roland said solemnly.

If it was the previous life, it would be almost impossible to find an unidentified eyeliner after the end of the long war, and the tombstone would probably only be left with something like “Your name is unknown, and your achievements will last forever.” inscription.

However, witches can change this unavoidable situation, so that every soldier who contributes to the destiny of mankind can be left in the long river of history.

“When the Kingdom of Eternal Winter is back under the control of the First Army, let “Black Money” cooperate with Asha to confirm his identity and origin.

”

If the murderer who killed him was still alive at that time, he would not escape the severe punishment of the law.

Nightingale nodded, “It would be great if the equipment you mentioned that can communicate across thousands of miles can be manufactured sooner.”

“Unfortunately, that’s not my specialty.” Roland couldn’t help but rubbed his forehead. He felt a headache when he thought of the circuit diagram that he forcibly memorized.

“Now you can finally understand how I felt during the exam.” Nightingale covered her mouth.

“But no matter how difficult it is, I will not fall asleep on the table like someone, and I can only hand in a blank paper in the end.” Roland glared at her, “In fact, I have almost completed the manufacturing of the prototype. ”

Yes, the radio project has never stopped, albeit very slowly.

Like the piston machine, after considering many plans from the Graycastle Design Bureau, he decided to choose two of them to proceed at the same time.

And these two are the spark transmitter and the AM transmitter.

The former is the originator of radio waves, with an extremely simple structure, without any electronic components, just using a transformer coil to increase the voltage to charge the capacitor until the voltage loaded on the capacitor between the spark gaps is high enough to break through the air, and then discharge the electricity. spark.

This part is quite similar to a lighter, except that the current passed by the spark is not wasted, but repeatedly oscillates between the capacitor and the inductor to generate electromagnetic waves, and finally emits these electromagnetic waves through the antenna.

In other words, as long as the power supply is turned on and off, intermittent electromagnetic bursts can be emitted-the receiver can translate it into a corresponding signal according to the length of the sound.

The so-called long and short telegram codes come from this.

Although it still sounds a little confusing, Roland adopted the most tricky method, that is, first let the radio project team of the Graycastle Design Bureau use readily available materials to create a usable real thing, and then copy the real thing.

For example, two pieces of tin foil are clamped up and down on a stack of oil paper, and then sealed with wax, it is a simple high-voltage capacitor.

The inductance is simpler, nothing more than winding a circle of wires on an insulating tube.

Without considering mass production or specifications of these devices, Roland can complete them by himself.

Although compared with those industrial products that are only the size of a fingernail after packaging, UU Reading www.sonicmtl.com They look bulky and simple, but the effect is basically the same.

Once the transmission tower was built, he could attempt the first wireless transmission experiment of this era.

However, the shortcomings of the spark transmitter are also obvious.

Even if it passed the test, before it could be put into official use, it still had to design a set of codes that matched the characters of the Kingdom, and the training of the sender and the receiver also required a lot of time.

In addition, the frequency spectrum of the spark transmitter is extremely wide, and only one transmitter can work within the same range, which is not suitable for front-line intelligence personnel.

So his ultimate goal is still an AM transmitter that uses tubes to amplify the signal.

The biggest advantage of the latter is that it can directly transmit voice signals.

In terms of principle, radio communication and telephone are very similar in essence, they both convert the vibration of sound into the change of electric current or electromagnetic wave, and then transform it into sound again after long-distance transmission to the other end.

It’s just that the frequency of the human voice is too low, making the wavelength of the signal wave too long, and the longer the wavelength, the larger the size of the required antenna—if the voice signal is directly transmitted, the antenna length may reach more than 100 kilometers. The above is an impossible thing to achieve.

So if you want to transmit the voice, you must take a carrier with a higher frequency.

This is what is called modulation.

After the new waveform mixed with the two is accepted, the listener must also filter out the high-frequency wave through a series of demodulation methods, leaving only the meaningful low-frequency wave before it can be converted into the final voice.

Once the AM transmitter is successful, both the First Army and the intelligence agencies will have real-time communication capabilities in a true sense.

For war, its significance is self-evident.
