Chapter 1313, “The Age of Information”

Greycastle, Neverwinter City.

A report on the Grand Duke Island battle and the Wolf Heart situation was sent to Roland two days later.

It takes a week longer than the previous letter from the northern region Eternal Night City to Neverwinter. The speed of such communication cannot be said to be huge. Whether it’s a short-haul delivery of a flight messenger or a long-distance journey of a steamship day and night, it is now integrated into a messaging system, and every important message will be equipped with a dedicated boat or even a plane. This time the report was sent by Tilly.

“It’s hard for you.” Roland asked Chans Drink warmly. “Is the situation over there?”

“Don’t know if you read the report?” Tilly took over The cup, gave him a look, “behaved so diligently, what are you in the heart? Isn’t my special machine still a little clue?”

“Hey…” behind Nightingale’s 憋laughter.

“How come, I have chosen the most suitable one from several programs. As long as Anna pulls out the space, I can start trial production immediately.” Roland said quickly, “You know Recently, several projects have reached the most critical step, she is really busy.”

“Look at Anna’s share, this time I will not care about you, brother.” Tilly will Drink a drink and wipe the mouth away from the office. “The Seagull is about to return, I will go back to the Aerial Knight school.”

“Don’t stay for a day?” He is slightly Surprised.

“No way, now the frontline can threaten the Seagull and Andrea of the Vault of Heaven Lord, and… I don’t want to miss any chance of revenge.” Tilly waved his back to him, “then I am gone, brother.”

Looking at the door that was re-covered, Nightingale sighed softly, “Everyone…have been working hard.”

If you can I hope that they will work hard on other aspects, not war. Roland bottom of heart floated this idea, but did not say it – because before the end of the War of Divine Will, no one could rest this burden until the fate of mankind was decided. It is no longer meaningful to say that this is in addition to 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 sentence. Can promptly release the retreat order, and successfully ambush a Devil Monarch, Edith Kant and Andrea, who are unseen in the sea, is undoubtedly the biggest hero of this battle. But again, the sender of the key intelligence can not be ignored – without this person’s desperate fight, there will be no victory behind.

“What are you going to do?” This event clearly attracted the attention of Nightingale.

“No matter what the original intention of sending out this secret letter, the name and merits of this person should not be forgotten.” Roland whispered. If it is a past life, it will be almost impossible to find an unidentified eyeliner after the long war. The tombstone may only leave something like “Your name is unknown, and your merits will last forever.” Inscription. But the witch can change this lasting situation, so that every soldier who contributes to the fate of mankind can stay in the history. “When the Kingdom of Eternal Winter returns to the control of the First Army, let “Black Money” cooperate with Asia 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. “If you said that you can cross a thousand miles.” The communication equipment will be manufactured soon. “

“Unfortunately that is not my strength.” Roland couldn’t help but lick his forehead. When he thought of the circuit diagram that forced memory, he felt a headache.

“Now you can finally understand the feelings of my exam.” “Nightingale is covering his mouth.”

“But even if it’s hard, I won’t fall asleep on the table like someone, and I can only hand in a white roll,” Roland glanced at her. “In fact, I have already completed the manufacture of the prototype. “

That’s right, although the progress is extremely slow, the radio project hasn’t stopped.

Like the piston machine, after considering the many options of the Greycastle Design Bureau, he decided to choose Two of them are carried out simultaneously.

These two are spark transmitters and AM transmitters.

The former is the originator of radio communication, the structure is extremely simple, and there are no electronic originals. Only use the transformer coil to raise the voltage to charge the capacitor until the voltage applied between the spark gap is high enough to break through the air and then discharge the spark. This part is quite like a lighter, but the spark passes. The current is not wasted, but it is repeatedly oscillated between the capacitor and the inductor to generate electromagnetic waves, and finally through the antenna, these electromagnetic waves are emitted.

In other words, as long as the control power is turned on. In combination, an intermittent electromagnetic break can be issued – the listener can translate it into a corresponding signal according to the length of the sound. The so-called long and short telegraph code is thus Come on.

Although it sounds a bit confusing, Roland has taken the tricky approach by first making the Greycastle Design Bureau’s radio project team available with readily available materials. In fact, take the physical object.

For example, put two pieces of tin foil on a stack of oil paper and seal it with wax, which is a simple high-voltage capacitor.

The inductance is even simpler, it is nothing more than wrapping a circle of wires around the insulating tube.

These devices are not considered for mass production, nor the layout of the specifications, Roland can rely on their own Finished. Although compared with those industrial products that are only nail-sized after packaging, they are both large and simple, but the effect is basically the same. When the tower is built, he can try the first wireless report test of this era.

However, the shortcomings of the Spark Transmitter are also obvious.

Even if it passes the test, if you want to put it into formal use, you have to design a code that matches the Kingdom text. , the training of the sender and the recipient It also takes a lot of time. In addition, the spark transmitter has a very wide spectrum, and only one transmitter can work in the same range, which is not suitable for frontline intelligence personnel.

So his ultimate goal remains It is an amplitude modulation transmitter that uses a tube to amplify the signal.

The biggest advantage of the latter is that it can directly propagate the voice signal.

In principle, radio communication and telephony are essentially They are very similar, which converts the oscillation of sound into a change of current or electromagnetic wave. After long-distance transmission to the other end, it is converted into sound again. Only the human audio frequency is too low, so the wavelength of the signal wave is too long, and the wavelength is longer. Long, the size of the required antenna is also larger – if the voice signal is directly transmitted, the antenna length may be more than 100 kilometers, which is unachievable in engineering.

So if you want to pass the voice out, you have to take a higher frequency carrier.

This is the so-called modulation.

After the new waveforms of the two are mixed, the listener must also filter 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 AM transmitter is successful, both the First Army and the intelligence agency will have real-time communication capabilities.

For war, its meaning is self-evident.
