"We are originally an experimental unit. One hundred thousand is a lot. If we are assigned to everyone in our district seven, we will have to pay 200 yuan per person..." Yuan Ying said with a smile.

Wang Shunyi's mouth twitched: "Yuan Ying, this contains materials and other expenses, not for you to give bonuses to employees!"

When Liu Yijiu heard this, he didn't know what to say.

He even had some doubts whether he could get this equipment out within one month when working with the young female manager who is said to have rich technical experience and strong political skills.

Yuan Ying grinned, "Don't worry, Director, I'm just talking. How could our project research funds be misappropriated at will!"

After saying that, they took Liu Yijiu and Wang Shunyi to their conference room.

District 7 is different from District 3 and other areas, because most of them are the production and research and development of precision components. The workshop is not a large brick-and-wood factory building, but several three to five-story buildings. There are corridors outside, just like the dormitory buildings of District 3 of Liu Yijiu and others.

"Comrades, stop for a while. We are here to go to the business. Let's put your time-passing projects aside first. Let's do your business after finishing our business. Let's introduce it first. This is the legendary Liu Yijiu. Everyone is queer!" In the technical research and development room, as soon as they entered the door, Yuan Ying looked loud and howled inside.

This sound is even more than the roar of the Hedong lion.

When the people inside heard this, they immediately put down their work and looked at the door. It was like the difference between the gorillas when they first entered the zoo. Why do these guys look so strangely in kindergarten children?

Then, the applause rang rhythmically.

Just like the kind of applause in the army, this really made Liu Yijiu feel a little strange. Has it always been implemented in military management? This is a bit incredible. After all, scientific research is different from production workshops. There is a fixed time for the workshop to work every day, and when you are busy, you won’t work overtime day and night like doing scientific research. When you are tired, you will rest for a while, sleep for a while, and then get up to continue working.

The technicians here are very different from other places in the entire base. Many of them are middle-aged people, rather than the other areas, which are all old men.

"Everyone sit down a little bit. Don't miss it when the time comes. I can tell you that this is the first scientific research task of our unit. If it gets bad, don't blame the base leaders for not thinking about us in the future." Just like the kindergarten teacher, let a group of scientific researchers wearing Zhongshan suits get closer, so that it is convenient to listen to Liu Yijiu standing in front of the blackboard of the demonstration and talk about the project requirements and technology.

Liu Yijiu was really curious about this area.

This is like encountering an extremely simple and primitive tribe in a complex city.

After throwing away the thoughts in his mind, Liu Yijiu was not polite. After introducing himself directly, he began to raise his requirements for individual communication equipment in special combat environments: "We need to be small in size and have longer battery life, higher confidentiality and better communication quality..."

When Liu Yijiu was telling the request, everyone below was holding a pen to record on his own notebook. No one asked any questions at all.

"At present, given the domestic technical conditions, material conditions and production technology, my personal opinion is to use the radio intercom used by military communication stations to transmit signals. This way, relatively mature frequency packets can be used for anti-monitoring. After all, this is a communication equipment used for performing tasks behind enemy lines. In addition, the binary array group is used internally, and the frequency is actually written into the machine. At present, for this concept, I have designed an inexperienced solution, and I hope everyone can discuss it together..." After Liu Yijiu explained the detailed technical requirements, he began to draw pictures on the blackboard behind him.

And while drawing, he explained what component this is and what functions it is used to implement.

After all, the technology of wireless intercom is not too responsible, it is only used in a small range. It does not require a very wide area like the military's high-power radio station.

"Because the soldiers have more equipment during special operations, our communication device cannot be large in size and also need to reduce weight. The battery originally used by domestic communication devices is not suitable for us. We need a new model of battery with stronger power storage capacity..."

Liu Yijiu drew a walkie-talkie structure sketch on the blackboard that was much smaller than the elder brother, and marked each part with chalk of different colors.

After he finished drawing, he realized that the people below were staring at him blankly.

"What's wrong?" Liu Yijiu asked with a frown.

Didn’t they all say they were elites? How could they not even understand these?

"Comrade Liu, it seems difficult to achieve what you said with the technologies reserved by our base. Perhaps, I guess we may not have one in our country..." Liu Yijiu is a monster. Yuan Ying didn't believe it at first, but now he has to believe it.

"For example?" Liu Yijiu was very confused. These are not the most advanced digital signal communication equipment!

The structure is simple and the technology is universal. After ten or twenty years, even primary school students who have learned this basic knowledge can be assembled.

"We won't talk about whether this small body shape can be realized. Currently, the intercoms used in domestic military equipment are more than 20 centimeters long, and the signal range will not exceed five kilometers..." Yuan Ying thought Liu Yijiu was stunning, after all, this is technical research and development.

No wonder the base gave 100,000 yuan in funding. At first she thought that the base specially allocated more funds to take care of District 7!

"Many designs have been modified here. The semiconductor uses the latest purified round crystal silicon in the base, and at the same time adds a simple amplified signal output and reception circuit..." Liu Yijiu was speechless.

They are experts, but they are just an amateur!

Wang Shunyi didn't understand the radio at all, so he sat aside and was dozing off when he heard it.

"What is a binary array group?" Someone asked a basic question that made Liu Yijiu crazy. These questions were not what these experts need to ask.

However, when you think that the Republic is weak in electronics, it is not as weak as it can be, and radios may not necessarily study computers. But does this have anything to do with computers? What do these people fiddling with in the base all day long?

"This is how the binary array group is. According to our needs, twenty diodes are connected through circuits. These twenty-four diodes form a twenty-four binary encoding to control the frequency of our intercom signal... After the transmitter and receiver are connected, since there is a binary array group to control the frequency conversion within the signal range, within the signal range, all connected communication terminals will be transferred to the set next frequency at the same time, so as not to affect our own communication. If the enemy wants to monitor, a large number of radio stations will need to monitor all frequencies... and each terminal can act as a reflector and receiver, so that it can realize the communication of multiple people in groups even if they communicate..." Liu Yijiu explained this carefully.

Looking at these people, their original confusion disappeared, and instead they were some worries, some frowning and thinking about something.

"Master Liu, are these the most advanced communication technologies in China?" Yuan Ying understood the technologies introduced by Liu Yijiu.

But it will be very difficult to achieve.

Theories are one thing, and it is another to make them into reality.

"I don't know. This was learned from some academic journals and from my teachers when I was in school..." Anyway, Liu Yijiu couldn't explain it now, and it was pushed to the teachers who he himself didn't know who there were.

"If the material problem can be solved, I don't have much problem with making the physical object, but this battery..."

"The battery uses lithium batteries to charge energy. It can be recycled repeatedly. Two 10v lithium battery blocks are installed in series in an intercom, so that the transmission power can reach about 20 watts. The signal range is about fifteen kilometers..." Liu Yijiu also marked the battery structure diagram and materials.

Anyway, as long as they have this foundation, they will develop new technologies in this area in the future.

In this kind of environment in the mountains that is not affected or disturbed by the outside world, if you do technical research, as long as you have enough materials and funds, the results will be very huge.

Of course, all of this requires someone to help them find their direction of development based on these.

It took a whole day to explain all the techniques in it thoroughly, and then let Yuan Ying and the others find materials according to the design, and he didn't care about it.

What he needs to do is this job.

If he does everything himself, he will be exhausted and he will not be able to make the Republican work system progress, right?

"Do you think they can get this out within the time you specified? Why do I feel that they don't seem to understand what they said to you at all!" On the way back, Wang Shunyi looked at Liu Yijiu strangely for a long time. After Liu Yijiu felt uncomfortable all over, he asked.

Liu Yijiu nodded: "According to their situation, the physical object should be able to be taken out within ten days. After some improvements, it should be able to reach the level I want within twenty days. Also, the battery case is not just for this, I also need to use it to create a tactical flashlight. I forgot to explain this matter to them..."

This is not a complicated thing.

What is really complicated is a single-soldier communication terminal that needs to get digital signals in the future.

That thing is too expensive and is not suitable for now! (To be continued...)

ps: Brothers, Hulu still fulfilled his promise! Although it was twelve o'clock.

I hope my brothers can continue to make their monthly tickets. Today, we have exploded the sixth place chrysanthemums on the new book monthly ticket list! Although it is very short, although the gourd chrysanthemums were quickly blown back by him!

They are the defenders, we are the attackers! Please assist in monthly tickets! Keep exploding, don’t worry that we will be exploded again after the explosion! This is attacking the mountain!

The monthly tickets and the monthly tickets in your hands are thrown out, otherwise the s75 in the doctor's hand will be aimed at you! We are not afraid of failure, we can continue to write about Captain Yang Wei's tragic heroism! Military industry, if you have difficulties, you have to go to, and if you have no difficulties, you have to go to create difficulties!

Come on! S75 lacks ammunition!
Chapter completed!
