Grey Castle, no winter city.
Reports about the war on the Dagong Island and the situation in the wolf heart were delivered to Roland two days later.
Compared to the previous letters sent from Yongye City in the North to Wudong, it took a week to send letters from Yongye City in the North. This speed of communication has made great progress.
Whether it is the short-distance express of the flight messenger or the long-distance running of the steamship day and night, they are now integrated into part of the messaging system. Every important message will be equipped with a special man and a special ship or even a plane. This time the report was sent by Tilly.
Thanks a lot.Roland asked about the warmth and handed over Chaos drinks. Is the situation there okay?
You can't tell by reading the report?Tilly took the cup and glanced at him. He acted so attentively, why are you feeling guilty?Is it because my dedicated machine has no clue yet?
Puff... The nightingale's laughter came from behind.
How could it be? I have chosen the most suitable one from several plans. As long as Anna takes time out, she can start trial production immediately.Roland hurriedly said, "You know that several projects have reached the most critical step recently, and she is really too busy to do it."
For Anna's sake, I won't bother you this time, brother.Tilly drank the drink in one sip, wiped her mouth and walked out of the office. The Seagull was about to return, so I'll go back to the Air Knights Academy first.
Don't stay for a day?He said a little surprised.
There is no way. Now the only ones that can threaten the Lord of the Sky on the front line are the Seagull and Andrea, and... I don't want to miss any opportunity to revenge.Tilly waved her back to him, then I'm leaving, brother.
Looking at the door that was closed again, Nightingale sighed softly, "Everyone... is working hard."
If I can, I would rather they work hard on other aspects than war.
Roland had such a thought in his heart, but he did not say it because before the war of divine will end and before the fate of mankind was decided, no one could take this burden.
Now, there is no meaning to say this except 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.
Being able to issue retreat orders in time and successfully ambush a devil lord who comes and goes without a trace in the vast sea, Itiskand and Andrea are undoubtedly the biggest contributors to this battle.
But in the same way, the sender of key information should not ignore that without this person's desperate attempt, there would be no victory in the future.
What are you going to do?This incident obviously attracted the attention of the Nightingale.
No matter what his original intention of sending this secret letter, the person's name and achievements should not be forgotten.Roland said in a deep voice.
If it was a previous life, it would be almost impossible to find an unknown eyeliner after the long war was over. I am afraid that there would be only an inscription on the tombstone that is similar to your name, no one knows, and your achievements will last forever.
However, the witch can change this last resort, so that every warrior who contributes to the fate of mankind can be famous in the long river of history.
When the Yongdong Kingdom returns to the control of the First Army, let Hei Qian cooperate with Axia to confirm his identity and origin.
If the murderer who killed him was still alive at that time, he would definitely not be able to escape the severe punishment of the law.
Nightingale nodded. It would be great if the equipment you mentioned that could communicate across thousands of miles was built early.
Unfortunately, that's not my strength.Roland couldn't help but rub his forehead. When he thought of the circuit diagram that he forced to remember, he felt extremely headache.
Now you can finally understand how I felt during the exam.Nightingale covered her mouth and said.
But no matter how difficult it is, I will not fall asleep on the table like someone. In the end, I can only hand in a blank paper. Roland glared at her. In fact, I am almost finished making the prototype.
Yes, despite the extremely slow progress, the radio project has never stopped.
Like the piston machine, after considering the numerous plans of the Grayburg Design Bureau, he decided to choose two of them at the same time.
And these two are spark transmitters and AMMO transmitters.
The former is the originator of radio waves. It has extremely simple structure and does not have any electronic components. It simply uses a transformer coil to increase the voltage to charge the capacitor until the voltage loaded between the spark gaps is high enough to break through the air, and then emits electric sparks.
This part is quite like a lighter, but the current transmitted by the spark is not wasted, but it repeatedly oscillates between the capacitor and the inductor, causing electromagnetic waves to be generated, and finally through the antenna, the electromagnetic breaks are emitted.
In other words, as long as the power is controlled to open and close, the intermittent electromagnetic breaker can be sent out. According to the length of the sound, the listener can translate it into the corresponding signal.
The so-called long and short telegram code comes from this.
Although it still sounds a little confused, Roland used the most trick, which was to first let the radio project team of the Grayburg Design Bureau use available materials to create a practical object that could be used, and then copy it.
For example, sandwich two pieces of tin foil on a stack of oil paper and seal it with wax, which is a simple high-voltage capacitor.
The inductor is simpler, it is nothing more than wrapping wires around the insulating tube.
These equipment can be completed by Roland alone without considering mass production or specifications.
Although they appear thick and simple compared to those industrial products that are only the size of nails after being encapsulated, the effects are basically the same.
When the transmission tower is built, he will be able to try to conduct the first wireless transmission test of this era.
However, the disadvantages of the spark transmitter are also obvious.
Even if it passes the test, if it wants to be formally used, it has to design a set of codes that match the kingdom text, and the trainees and recipients will take a lot of time.
In addition, the spectrum of the spark transmitter is extremely wide, and only one transmitter can work within the same range, and is not suitable for front-line intelligence personnel.
Therefore, his ultimate goal is to use an amplitude modulation transmitter to amplify the signal using electron tubes.
The biggest advantage of the latter is that it can directly propagate voice signals.
From a principle alone, radio communication and telephone are essentially very similar. They both convert the oscillation of sound into changes in current or electromagnetic waves, and then change it to sound after being transmitted from a long distance.
It’s just that the voice frequency of a person is too low, which makes the wavelength of the signal wave too long. The longer the wavelength, the larger the size of the required antenna. If the voice signal is directly transmitted, the length of the antenna may reach more than 100 kilometers, which is an unachievable thing in engineering.
Therefore, if you want to deliver voice, you must ride on a higher frequency carrier.
This is exactly what is called modulation.
After the new waveform mixed with the two is accepted, the listener must filter out the high-frequency waves through a series of demodulation methods, leaving only meaningful low-frequency waves to be converted into the final voice.
Once the AMMO transmitter is successful, both the First Army and the intelligence agency will truly have the ability to communicate in real time.
For war, its significance is self-evident.
