"Yes, the technology was not bad during World War I, and at that time, Einstein's theory of relativity came out......"

Someone in the crowd chimed in.

"If you build a Marconi transceiver on horseback, or on a carriage, you should be able to ......"

At this time, Xiao Fei did not join the argument, and responded to everyone while talking, his attention was still on the physical object in his hand.

"What should be possible, it doesn't seem to be quite sure......"

Someone in the crowd complained.

"Xiao Fei, can you make it clear? Where are the technical bottlenecks? ”

Someone in the crowd finally asked a quality question.

"Electronic communication products have high technical requirements for the overall industrial development level of the society, and need to have a lot of relevant technical conditions, I am still unclear for a while, in short, first of all, it depends on the development level of our metal and non-metal materials industry."

Everyone was silent for a while, Xiao Fei didn't care about everyone's silence, just said to himself, and then turned back to the onlookers and sighed:

"I've finally been able to touch the real thing, which I've only seen in photographs and museums through glass cases before."

"Xiao Xiao, I heard you say just now that the communication distance of this thing seems to be less than fifty kilometers, right? Do you think we can do long-range radio communication? In the future, our communications, especially ship communications, will require more powerful transceivers. ”

Gu Jin didn't know when he joined the ranks of onlookers, he stood behind everyone and said to Xiao Fei.

Hearing Captain Gu's question, Xiao Fei quickly jumped off the shelf and immediately responded:

"The captain of the ship is Mingjian, this equipment is used on the plane, in order to be light, it is indeed at the expense of the communication distance, in fact, if the power is a little larger, the communication distance is far more than 50 kilometers, 500 kilometers is very easy.

However, it will definitely not be lightweight, and if you don't consider mobility, it is possible to build a roadbed that reaches 2,000 kilometers in the initial stage. ”

"Oh? What about the five large ones in the back? ”

Someone in the crowd asked.

"The big ones are actually slightly easier to replicate than the small ones, but the ...... Or as I just said, in order to achieve complete replication in the new world, industrial conditions are needed, and in addition, in the initial stage, the volume may be larger, the performance, and the communication distance may be shorter, especially the problem of the battery......"

Xiao Fei looked at the large iron cabinet stacked behind the iron shelf and said.

"It's okay, it's better than nothing......"

"It seems that we have to do it slowly, this thing is restricted by the overall level of industrial development, and it cannot be achieved overnight."

Someone in the crowd immediately nodded their heads to show their understanding of Xiao Fei's statement.

"Yes, guys, in my personal opinion, in fact, Anna brought this thing to us, the main purpose is probably to give us a physical reference, we should be able to make a higher power transmitter.

Of course, it must be bulky and bulky at first...... Captain Gu, I can be responsible for saying that no matter how bulky it is, it should be no problem to load it on the ship.

As long as the displacement of the ship allows, including the power generation equipment, there is no problem with the base station type Marconi transceiver system weighing one or two tons on board.

Moreover, the radio communication environment of the new world is definitely better than that of the old world, and in terms of communication distance, you can rest assured that in the first few years, I had a communication distance of hundreds or thousands of kilometers. ”

When Xiao Fei said this, he saw a relaxed expression on everyone's faces, and continued:

"Of course, even if it is copied, it will take time, and there is no problem with the accumulation of technology, because we have completely mastered these technologies, and I think the most critical bottleneck at the moment is the chemical aspect.

In particular, high-power batteries, even if they are very primitive liquid semi-liquid batteries, need Mr. Zhao to get out the three acids and two alkalis before they can achieve it. ”

"Okay, so let's talk about it......

Someone in the crowd pointed to a row of small wooden boxes on the iron shelf and said to Xiao Fei.

"Ah...... What's this...... The U.S. military's portable amplitude modulation wireless radio SCR536, the original goods!

I believe that in our current radio communication environment, the signal of this model walkie-talkie will definitely cover the whole island, and this military walkie-talkie became the basis of front-line communications during World War II, and the manufacturer Calvin, which was later called the company called Motorola......"

Xiao Fei stood in front of everyone and talked eloquently, and there were more and more listeners around him......

Twenty-two-year-old Xiao Fei will definitely be misunderstood from his appearance, in a word, he looks old.

He is a student majoring in electronic engineering at a university and a radio amateur.

Xiao Fei is a radio enthusiast who has been assembling ore radios since he was in elementary school, and he is also a "troublemaker" who has been registered by the local management committee in his hometown many times.

Later, his parents died in a car accident and were adopted by his uncle, but his aunt did not allow it, but fortunately, his parents left some inheritance, so that he would not have to live under the eaves of others, Xiao Fei left the so-called home at the age of eighteen, and went to school and worked alone in the south.

Once, in the process of working for a radio base station company, because of his professionalism and diligence, he was favored by the boss of this company, saying that he planned to give him a "chance" with a high salary---- and asked him to be responsible for making a "radio communication base station" in the mountainous area.

Although Xiao Fei is young, he also knows the trickiness of this mountainous base station---- which may be a communication station with incomplete procedures, similar to the "incomplete property rights house" developed in some villages.

He told the boss that if this station was discovered, he might have to enter the game, and then he would be done with the rest of his life.

However, the boss swore and showed him all kinds of legal certificates and attractive remuneration.

So, Xiao Fei took the job for the sake of money, but he didn't expect that not long after the base station was built, the boss had an incident in the east window, Xiao Fei finally got the news before he was arrested into the bureau, and Xiao Fei absconded without any hesitation.

Because he has a criminal record in his hometown, he is afraid that he may be sentenced to a heavy sentence if he is caught......

Xiao Fei, who was on the run, was extremely remorseful, hating himself for being dizzy! hate your own naivety, thinking that there is really a pie in the world......

Under the hesitation of self-pity, he thought of death, he can be said to have no relatives and no reason in this world, he will never go back to his uncle's house, he would rather die than go back!

So after a drunken getaway, he went to the beach, and he blended into the sea.

Of course, he was eventually fished out by Nike with a weird "net" that flashed blue light, and the rest of the story goes without saying.

Now, Xiao Fei, as the only radio professional in the entire crossing team, still has a lot of weight in everyone's minds.

"With the current conditions, can we build a communication device such as a walkie-talkie?"

At this time, someone in the crowd of onlookers asked questions.

"Your question is a bit complicated, as I just said, it depends on the level of our overall industrial development, especially the material industry and manufacturing industry......"

"It seems to have something to do with the chemical industry."

"Can we make transistors?"

"Don't dream, thank God if you can build the tube in the early days......"

"Tubes? Isn't it just something like a light bulb? ”

"Holy! Is it particularly related to the glass industry? ”

......

So everyone began to talk about it again, and after a while, someone finally remembered that Xiao Fei was the most vocal person in this regard, so someone asked:

"Xiao Fei, what do you think?"
