Chapter 188 The telegram is almost ready to use

The construction of Wessenburg University has not stopped in the past three years. New buildings have continued to expand along the lake, and many single-family villas have appeared in the mountains to the south, where professors live.

The lake in front of the university has begun to be called "University Lake", and no one uses the original name.

Heinrich resigned from the Royal Mages last year and moved to the University of Wessenburg as a professor. He and his students and some colleagues formed the "Lightning Academy" to teach and research electricity magic.

Because Frederick gave him a large investment last year, there are a lot of students who signed up for this college this year, and everyone came here to make a fortune in the future.

Under his example, the hearts of the royal mage group were unstable for a while, especially those new mages who had just joined the group for a few years and were still struggling with qualifications, and they also wanted to change jobs.

After all, the Royal Mages are the strategic force of the Rhineland Alliance. Frederick didn't want to dig too much, so he let them form a mutual aid and co-construction unit with Weissburg University. On the one hand, the members of the Mages who wanted to make money came to the university to teach and do research. On the one hand, students who are interested in joining the army are allowed to practice in the mage group.

However, Frederick made a lot of complaints about the Royal Mages. He promised [-] florins last year to let them produce a phonograph that can be promoted.

Frederick found Heinrich in a laboratory with red bricks and red tiles that was similar to a factory building. He let Lixiao wander around by himself, and then went in to see what they were doing.

In the more than a year since the broadcast was launched, Heinrich and the others have some new results.

A few students are assembling the antenna. This kind of antenna has a ring of iron sheets on the outside and empty magic crystal powder in the middle. It is more than one meter long and as thick as chopsticks.

This antenna allows the transmitter to carry a signal farther, and also allows the receiver to pick up weaker signals.

In April of this year, the Wesson Army supporting the Wessen Territory relied on the new wireless communication system to command a company to surround an enemy camp that was five times larger than itself in three ways at night.

Ever since, Frederick had a big plan-to get the telegram out.

However, if this plan is to be perfected, it still needs to improve the equipment, which is the focus of Heinrich's current work.

When Frederick arrived, Heinrich had just handcrafted a magic circle, which can be directly inserted into the magic circle that sends signals like a graphics card, and its function is to determine the frequency of the signal.

"Principal," Heinrich asked after looking up and seeing him, "what's the matter?"

Frederick replied: "It's nothing, just come and take a look, you are busy with your work."

Seeing that he was fine, Heinrich went about his own affairs without saying a word, and began to invite my students to come over to do experiments.

Frederick didn't understand Morse code, so let's make it up now. It's not difficult to make up a set of Rhine letters, Pulan letters, numbers and punctuation marks.

Today, there is a new set of equipment in the laboratory, which is long like a box. Pass the black paper tape through it. There are empty slots on the top cover for letters. hole.

On the other side, students wind up the clockwork of the paper feeding device, and the gears driven by the clockwork control a pair of rubber rollers to advance the paper tape.

The paper tape will pass through a device, the upper part of which will emit light, and the lower part is a light-sensitive magic resistance. The amount of magical elements passing through is proportional to the intensity of the light shining on it. The holes in the paper tape will shine on it when passing through the time , the signal sent after turning on the transmitter is also different.

Frederick watched quietly from the side as they sent out the words "The principal is watching!"

After about 5 minutes, there was movement on the receiver side, and the students immediately opened the paper tape feeding device there. Just as the white paper tape was sent out half the size of a palm, the steel needles on the upper and lower sides of the paper tape flickered continuously. The electric spark left a string of black traces.

The content was quickly translated, "Salute to the headmaster - Yu Nuremberg".

Frederick nodded in satisfaction, but there were still some problems. Whether it was "·" or "-", the received signal was relatively long.

"What's the matter?" He asked Heinrich. If this problem is not solved well, maybe "·" will become "-", which will eventually lead to misreading.

Heinrich replied: "The speed of paper feeding is different, some are fast and some are slow, and some are difficult to unify."

Frederick thought for a while, and the escapement of the clock should be able to control the speed of the roller, so he said, "Let me solve this small problem. I may go out this autumn or next spring, can I catch up?"

Heinrich replied affirmatively: "It would be a little troublesome if it was a voice broadcast like that, but the current dot and horizontal signals can be transmitted very far, but I still recommend building a relay station every 200 kilometers to avoid signal distortion. .”

Frederick nodded and said, "I've already arranged for people to buy land. Recently, I have produced more voice communicators for the army. They can be used during expeditions, and they might sell for a fortune."

When Heinrich heard that there was money to be made, Heinrich naturally agreed, and then said: "I have an idea, the communicator sold is equipped with a self-destruct device, and if someone tries to dismantle it by himself, it will explode."

The corner of Frederick's mouth twitched, and he nodded in agreement.

He went on to say: "I plan to build a number of telegraph stations in the major cities of the Rhineland Alliance, and then build important ports in the North Sea and the Inner Sea. These telegraph stations can transmit information to each other, and we can study in this direction next."

"In terms of speeding up the input and output of information, maybe you can refer to Professor Ogilvy's calculator. You can discuss it with him when he is free after a while."

Heinrich immediately took out his notebook and wrote it down.

Frederick signaled him to go out with himself, and the two came to Heinrich's office, and said after blocking the sound: "I also want a small communicator that can communicate over long distances, mainly for spies. That requires leaving specific frequencies for them."

"No problem." Heinrich agreed, "I will pre-allocate the frequencies for radio, telegraph and certain communications."

Frederick said again: "I have an idea, can the radio be used as an invisible lighthouse to determine the position of ships at sea."

"For example, a ship at sea can receive broadcasts from two places, and then measure the direction in which the broadcast is sent, and how many degrees it is relative to the true north. With these two data, you can map Measure your position on the Internet."

After hearing this, Heinrich thought about it, and picked up the white paper next to him to write and draw.

Frederick didn't bother him, just sat there quietly and made him a pot of tea.

"Theoretically it is possible." When Heinrich looked up, the sunset had covered the sky, "The broadcast signal can be shielded by materials with high magic resistance, so make a shielding tube like a wooden barrel, and its The signal received is the strongest when the opening faces in which direction, and the transmitter is in that direction. Although there will be some errors, I think it is enough for sea use.”

After hearing this, Frederick thought for a while, nodded and said, "This method sounds feasible."

"This is a big business. Coastal cities want to buy broadcasting systems, so the radios are also sold. Those captains who are not short of money will definitely buy them. It doesn't matter if they are more expensive, after all, they can save their lives."

Bright smiles appeared on the faces of the two of them together, as if they saw countless gold coins waving towards them.
