"We're an experimental unit. 100,000, which is also a lot. If it were distributed to all of us in the seventh district, one person would get two hundred yuan......" Yuan Ying said with a smile.

Wang Shunyi suddenly twitched the corner of his mouth: "Yuan Ying, this includes 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 that he would be able to get the equipment out of a month in cooperation with the young female manager in front of him, who was said to be technically experienced and politically competent.

Yuan Ying grinned, "Don't worry, director, I'm just talking." How can we embezzle the scientific research funds of our project at will! ”

After finishing speaking, he took Liu Yijiu and Wang Shunyi to their conference room.

Zone 7 is different from Zone 3 and several other areas, because most of them are for the production and research and development of precision components, and the workshops are not large brick and wood buildings, but several buildings with three to five floors. There is a corridor outside, just like the dormitory building of Liu Yijiu's third district.

"Comrades, stop for a moment, let's do business here, put aside all your projects to pass the time, and then go to work on yours after we're done with the business here. Let's introduce first, this is the legendary Liu Yijiu, everyone chirp! In the technology research and development room, as soon as he entered the door, Yuan Ying had a loud voice and howled inside.

This voice is even more Hedong lion's roar than the roar of the Hedong lion.

When the people inside heard this, they immediately put down their work and looked towards the door. It's like the first time you go to the zoo and see the gorillas, why do these guys look so strange.

Then, the applause rang out rhythmically.

It's like the kind of applause in the army. This really made Liu Yijiu feel a little strange, has it always been a militarized management? It's kind of incredible. After all, scientific research is not the same as the production workshop. There is a fixed time for the workshop to work every day, and it will not be like doing scientific research day and night when you are busy, and when you are tired, you will rest for a while, and if you are sleepy, you will sleep for a while, and then get up and continue to work.

The technicians here are very different from the rest of the entire base, many of them are middle-aged, not a bunch of old men in other districts.

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

For this district, Liu Yijiu's heart is really full of curiosity.

It's like encountering a simple, independent primitive tribe in a complex city.

Throwing off the thoughts in his mind, Liu Yijiu was not polite. After introducing himself directly, he began to put forward his requirements for individual communication equipment in the special operations environment: "For this set of communication equipment, we need to be small in size and have a longer battery life. Higher confidentiality and better quality of communication......"

When Liu Yijiu told the request, the people below were holding pens and recording them in their small notebooks. No one asked any questions at all.

"At present, in view of the domestic technical conditions, material situation and production process. My personal opinion is the use of radio intercoms that use FM transmission signals used by military communication stations. This allows the use of more mature frequency groupings for snooping prevention. After all, this is communications equipment used to carry out tasks behind enemy lines. Other than that. The internal binary array is used, and the frequencies are written into the machine. Presently. For this idea, I have designed a not very mature plan, and I hope everyone can discuss it together......" After Liu Yijiu explained the detailed technical requirements, he began to draw on the blackboard behind him.

And while drawing, he explained what kind of part it was and what kind of function it was used for.

After all, the technology of wireless walkie-talkies is not too responsible, and it is only used in a small area. There is no need to cover a very wide area, as is the case with the military's high-power radios.

"Due to the fact that the soldiers have more equipment on their bodies during the special operation, our communication device cannot be large in size and at the same time, it has to reduce the weight. The original domestic communication device used this kind of battery, not suitable for our use, we need a new type of battery with stronger power storage capacity......"

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

After he finished painting, he found that the people below were staring at him blankly.

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

Isn't it said that they are all elites? How can you not even understand this?

"Comrade Xiao Liu, these things you are talking about seem to be difficult to achieve with the technologies reserved in our base. Perhaps, I don't think we have any ...... in China" Liu Yijiu is a demon, Yuan Ying didn't believe it originally, but now he has to believe it.

"For example?" Liu Yijiu was very puzzled, these are not the most advanced digital signal communication equipment!

The structure is simple and the technology is universal. In another ten or twenty years, even elementary school students who have learned a little bit of the basics will be able to assemble it.

"Let's not talk about whether this small size can be realized. At present, the walkie-talkies equipped by the domestic army are more than 20 centimeters long, and the signal range will not exceed five kilometers...... "Yuan Ying doesn't think Liu Yijiu is whimsical, after all, this is technology research and development.

No wonder the base gave 100,000 yuan, she thought at first that the base had deliberately allocated more funds to take care of the seventh district!

"Many of the designs have been modified, and the semiconductors use the latest purified wafer silicon in the base, and at the same time add a simple amplified signal output and reception circuit......" Liu Yijiu was speechless for a moment.

They're experts, they're just amateurs!

Wang Shunyi didn't understand radio at all, so he sat on the side and dozed off.

"What is a binary array group?" Someone raised a basic question that made Liu Yijiu crazy. These questions. He didn't think the experts needed to ask.

However, when I think that the republic is already weak in electronics, it cannot be weaker, and those who are engaged in radio may not necessarily study computer things. But does this have anything to do with computers? What are these people fiddling around around with in the base all day?

"Binary array groups, that's it. According to our needs, 20 diodes are connected through the circuit, and these 24 diodes form a 24-bit binary code to control the signal frequency of our walkie-talkie...... After the transmitter and receiver are connected, because there is a binary array group to control the frequency conversion, within the signal range, all connected communication terminals will be switched to the next set frequency at the same time, so as not to affect our own communication, if the enemy wants to listen. It requires a large number of radio stations 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 a group," Liu Yijiu carefully recounted this.

Looking at these people again, the original confusion disappeared, replaced by some worries, and some frowned and thought about something.

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

But it's going to be very difficult to get there.

Theory is one thing. It's another thing to get it into a physical object.

"I don't know. This is what I learned from some academic journals and from my teachers when I was in school...... "Anyway, now Liu Yijiu can't explain it, and it's all pushed on the head of a teacher who he doesn't even know who it is."

"If I can solve the material problem, I don't have much problem making the real thing, but this battery ......"

"The battery is charged with lithium batteries. And it can be recycled repeatedly, and two 10V lithium battery blocks are installed in series in a walkie-talkie, so that the transmission power can reach about 20W. The signal range is about 15 kilometers...... "Liu Yijiu simply marked out the structural drawings and materials of the battery.

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

In this environment in the mountains, which is not affected by external influences and interference. Engage in technical research, as long as there are sufficient materials and funds. The results will be enormous.

Of course, all of this needs someone to find their way forward on these foundations.

It took a whole day for Liu Yijiu to explain all the techniques thoroughly, and then asked Yuan Ying and them to find materials according to the design, and he didn't care about it himself.

That's what he needs to do.

If he did everything himself, he would be tired to death, and it would be impossible for the republican labor system to progress, right?

"Do you think they'll be able to get this out of the time you allotted? I don't think they understand what you're saying at all! On the way back, Wang Shunyi looked at Liu Yijiu a little strangely for a long time, and felt uncomfortable in Liu Yijiu before asking.

Liu Yijiu nodded: "According to their situation, they should be able to come up with the physical object within ten days, and after some improvements, they should be able to reach the level I want within twenty days." Also, that battery case isn't just for that, I need to use it to make a tactical flashlight. I forgot to explain this to them just now......"

It's not a complicated thing.

What is really complicated is the individual soldier communication terminal that needs to get digital signals later.

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

PS: Brothers, the gourd still fulfilled its promise! Although it was past twelve o'clock.

I hope that the brothers' monthly passes can continue to be smashed out. Let's blow up the sixth-place chrysanthemum on the new book monthly ticket list today! Although it was very short, although the gourd chrysanthemum was quickly exploded back by him!

They are the defenders, we are the attackers! Ask for a monthly pass assist! Keep exploding, don't worry about being blown up again after the explosion! It's a mountain attack!

Monthly passes, all the monthly passes 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 the tragedy of Captain Yang Wei! In the military industry, if there are difficulties, you have to go up, and if there are no difficulties, you have to create difficulties!

Come on! The S75 is short of ammo!
