The American air force is an eternal scourge. How eternal. The heavy weapons on the position dare not leak out easily. If they leak out, just wait to be bombed. The American planes will come over in a moment and give you the position.
Throw a few tons of bombs on it, load it with thousands of rounds of ammunition, and then walk away. Regarding aircraft, the only thing Hancheng can solve is the number of anti-aircraft guns, but now the number of anti-aircraft guns has reached an unaffordable bottom. You
Can you imagine that the ammunition of an anti-aircraft artillery occupies a quarter of the country's production capacity? Logically speaking, if this consumption continues, is it the best choice to surrender early? Then why does New China have to fight to the death with the Americans?
Because we are afraid of what will happen if such a powerful country becomes our neighbor. If Tsarist Russia and Japan fight in the Northeast, the Qing government will be neutral?
History, sometimes, is a circle. You know clearly that such things will never happen, but they will still happen over and over again. Here in Hancheng, watching train after train of ashes being transported back to the country, this is already the frontline troops.
We have tried our best to collect volunteer soldiers, but there are still many soldiers who have fallen south of the 38th parallel and cannot return home. Some of these young soldiers have names, and some simply have only a code name, or simply write down the name of that unit. Anti-Japanese War
Han Cheng had seen a lot of them during the Civil War, but he didn't expect that such things would still happen in the Korean battlefield.
Hancheng walked past these trains. All the ammunition supplies transported by these trains had been unloaded. At the same time, there were also wires and various electronic components that Hancheng needed. Now Hancheng was going to do something again, something big.
things.
"I brought all these things to the predetermined location and prepared them, and everyone was ready for me!"
Han Cheng personally led the team and left with a few diesel generators. In fact, there are not many high-tech things nowadays. At least radar is not too difficult. As long as Han Cheng has a system. You
If you were to build a real radar using electron tubes, the circuit would make your head explode.
These components were all applied for as spare parts for front-line radio stations, otherwise they would not be approved. The division commanders in Hancheng knew very well what Hancheng had to do. If it was successful, they could complete the transfer within a limited time.
Then notify the anti-aircraft artillery group below to prepare, and then inflict a heavy price on the invading enemy aircraft.
"It's hard to get air defense radar. Why did Director Han suddenly say he can get it?"
"That is, if you were almost buried alive by an American plane bomb, do you think you would be able to feel angry?"
This does not mean that safety can be guaranteed on the front line. The bombing of Hancheng has not happened once or twice. The Americans have their own channels for information. Not only do they maintain this flexible artillery team, they also have to find a place for maintenance in the rear.
, they don’t believe that something that runs so fast doesn’t need maintenance.
The idea is actually right. There are right and wrong places to blow up, but this time it really made Hancheng anxious. After finally finding the best repair shop, it was blown up, and all the engineering facilities inside were gone.
It means something, it means that you need to use manpower to lift the things on the self-propelled artillery. You were doing it well at home, but suddenly your good friend came over and took everything away from you. Are you angry?
, are you in a hurry?
Naturally, they started building air defense radars. As for the consequences, Han Cheng really didn't care about the consequences. Anyway, he casually wrote a report and handed it to the headquarters. Anyway, he left a few words at the end, saying that he wanted to build air defense radars.
This thing is still a rarity in China. Basically, few people can understand how it works. The real radar may not appear until the Soviet Union provides assistance. Now the Soviet Union’s own radars are all secret, and it is impossible to consider directly
For sale, although various countries have now begun the research and development of radar, it is still at a relatively low level in general. Existing materials and components can be purchased. If they are put into the highly integrated model in the future,
It may not be possible.
It’s easy because it’s backward, and it’s simple because it’s advanced. In the final analysis, these radars still can’t break away from the shackles of electronic tubes. As long as you can’t break away, it’s easy to handle. Hancheng also specially found a few welders and welded a few
Big racks, these racks are antennas for transmitting and receiving signals. We don’t care whether they are easy to use or not, but let’s talk about whether they can be used.
Han Cheng was not idle either. He was busy with a soldering iron and wires. No one knew what he was going to do. After all, domestic experts are currently conducting research in other areas, and not all experts may be very professional.
When it comes to operations in Hancheng, there are still very few people like this.
Next to it are several shelves made of wooden boards. These shelves are used to fix electronic tubes and other components. These days, these things are all made of wood. On the one hand, it is easy to obtain materials, and on the other hand, it is not conductive. Dry wood is not
Conductive items, including old radios, also have wooden boards inside.
"Give me a wire for each shelf over there. Go and get ready!"
It stands to reason that Hancheng should find something that can display, but this thing is difficult to find, so he can only find some small light bulbs, find a few frames to install the small light bulbs neatly, and there is a buzzer next to it. Like
This kind of display panel can only see the light on and off. Wherever the light is on, it proves that there is an enemy. As for the so-called heading speed, I'm sorry, you are really making it difficult for me.
After all, this is not a specialized military radar. I can't calculate the plane's flight speed or takeoff time, let alone where he will be in a few minutes or when he will arrive.
A large densely packed board with light bulbs is just finished, and connected with wires below. As for the lifespan of this radar, it depends on how long the light bulb can last. After the circuits next to it are connected, start connecting these lines together with the circuits.
What is the NOR gate? This thing is actually difficult. Nowadays, all digital circuits are used. Find a powerful chip to simulate the functions of many circuits. If you use the electronic tube to try its functions one by one, that is not a good idea.
It takes a long time to put it together, and it is too difficult to integrate everything.
How could Han Cheng do this? Didn’t he rely on the system? In college, he took the analog circuit test four times, but failed every time. In the end, he had no choice but to ask the teacher for help to pass. It was lucky that the pass rate of the entire class was less than 5%.
Instead of using this circuit, it is not that easy to use analog circuits. If you are not particularly talented, you will not be able to make this thing.
Nowadays, these circuits still use tubes, so I’m afraid there are only hifi tube amps, and those things still have to be made with tubes. I don’t know why, but maybe I feel that such large tubes look classy, and small integrated circuits look a bit awkward.
Too cheap.
It’s quite helpless here. The coverage area of a radar composed of so many things is not far away, only about 500km. In fact, it is enough for the troops, and the volume is not small. Several division commanders because of this
Things almost started to fight. After this thing shines directly on the opposite side, Han Cheng can completely control the movement in the sky, and then deploy enough anti-aircraft artillery firepower to defend.
All in all, people have been very busy. The small radar position is basically completed. What will be done in the future? It depends on what the Americans will do next. If the Americans don't give up and send planes, this will
500km is enough time to evacuate many people.
The Americans did not know that behind the position they were facing, a huge thing rose quietly. This heavy fog covered a range of 500km, and it was already on top of the radar used by the Americans. At least some things were focused on key places first.
When the situation in key places is no longer critical, then change venues and continue living.
