The people at the test site where the radar car was located let out an amazing roar, but unfortunately, their "Ula" was finally directly suppressed by the even louder noise!

"Damn! What kind of sound is this, my eardrums are going to tear! The noise was too harsh, and Salinchkin also covered his ears and cursed, and his whole expression was distorted.

Yang Mingzhi, Yevlov, etc., etc., and even the four radar soldiers in the listening room.

The radar soldiers, led by Diana, finally witnessed this miraculous moment, and their watches were the same time as Holmnich's, without missing a second. In fact, Diana, who had been wearing headphones all the time, noticed that the electron tube, which symbolized the "existence of obstacles", began to flash red in the sixth second of the experiment. Before she could pay close attention, only ten seconds later, her ears heard the slightest noise.

And that's just the beginning!

As time went on, the noise really got worse and worse, so much so that she simply took off her headphones.

There is no need to match headphones anymore, thanks to the tweeter, I am afraid that the noise feedback converted by the radar echo is already a broadcast to the entire blacksmith village!

Two thousand meters above Homnitch, a hundred dandelions were slowly falling. Given by the breeze, they descend slowly and drift northward, constantly reflecting radar microwaves.

The radar, which has a power of up to 600K, receives these echoes perfectly through its large antenna that is ten meters long. The four girls in the listening room, their ecstasy quickly turned into a distorted expression, and they also covered their ears with their hands.

The culprit was indeed the loudspeaker.

In fact, as long as the four girls moved their hands and removed the microphone, the loud noise disappeared. In this case, Diana was still very witty, and in a hurry, she grabbed Solkina, who was about to make a move, put her head to her ear and shouted: "Stop! We want to let the people know that our radar is a great success! ”

No one stopped the tweeter from continuing to spread the heart-rending noise, and even worse, the noise was getting stronger!

This is actually because the reflective surface composed of floating "dandelions" is maximized, and the reflectivity reaches its peak.

Therefore, the noise originating from the northern part of the blacksmith village quickly spread throughout the blacksmith village. The vast majority of soldiers and civilians had no idea what was making such a terrible noise, as if a large group of cats were scratching the walls. People are uncomfortable, and some even feel their hearts tremble abnormally.

However, not everyone can rely on their patience to put up with this damn noise.

The annoying noise finally made Yevlov unbearable, for the simple reason that it had no intention of stopping at all.

He rushed out of the viewing platform with a brisk step, emotionally grabbed the collar of Yang Mingzhi, who was growing in front of the tweeter and calmly covering his ears, and asked in the loudest voice he could make: "What the hell are you doing?!" Can't stop this noise? ”

It's a pity that Yang Mingzhi almost only saw Captain Yevlov snorting with a big mouth. "You! What did you say?! ”

"I mean...... I! ”

Yevlov was a reckless man after all, and the noise really drove him crazy! I saw that he simply pulled out his revolver in front of Yang Mingzhi, ignoring the surprise of his old comrades-in-arms, and aimed the muzzle of the gun at the horn hanging on the wooden pole that was releasing a crazy noise, and ran out all the bullets.

The bullet silenced the horn and rescued tens of thousands of people who had fallen into mental pollution!

Yevlov, visibly still angry, gasped and continued to ask: "What the hell is going on! The noise almost killed me! ”

"So! You just beat the horn into a hornet's nest?! Yang Mingzhi slowly let go of his hands, and there was a hint of evil smile on the corner of his mouth!

"That's right! I'd rather be blown up by the Germans than be killed by this damn noise. ”

"Well, you don't want to think about what this noise represents?"

Asked by this, Yevlov was stunned. Even if he knew little about radar and telegraphs, he knew before the experiment that when the noise from the horn came out, it was the moment when the experiment was successful.

Then Yang Mingzhi became emotional, and his hands grabbed Yevlov's shoulders and shook violently: "Dear Davarich, we succeeded!" The radar succeeded! Even now, we receive radar echoes! ”

To be honest, the success of the radar did not excite people like Yevlov or even Salinchkin, who were not scientists after all. Their attitude towards the noise of the horn was also happy at first, and then they hoped that it would "shut up". Obviously, Yevlov saved everyone, but when everyone was quiet, they had to face such embarrassment - how to repair the broken horn?

Naturally, the arsenal was responsible for repairing the horns, and Rygushkov didn't have time to care about it at all. During this time, he and Popov have been shouldering all the pressure of radar manufacturing, although the horn is broken, and the equipment in the radar listening room is still intact!

The two ignored officers like Yang Mingzhi and took the lead in burrowing into the listening room.

And just when I entered this listening room, which was quite soundproof, my ears still echoed with an uncomfortable noise like a hundred cats scratching the wall.

Popov asked straight to the point: "Comrades! Are we still monitoring the falling rockets? ”

The appearance of the two also surprised Diana, who was a person who had added to the world, and immediately replied: "Yes! You see, the red light of the tube is very shiny, and you can hear the noise without wearing headphones, which indicates that there are a lot of obstacles in the high altitude in this direction that we are aiming at. This must be an experimental rocket, and they fall so slowly that we can get radar echoes all the time. ”

"That's great!" Popov stomped his feet with joy, and the experiment was a great success!

But it is Yang Mingzhi himself who really has the right to succeed in all this experiment. He stepped into the listening room, facing the noise and the flickering lights, and the excitement in his heart made it difficult for him to stand. There was no small space here, and he sat on a chair, and his hands trembled as he took the headphones handed by Diana.

Just by picking up the headphones, the noise was so loud that he didn't hurt his eardrums anymore.

"Alas! It's a pity we don't have an oscilloscope. If the microwave is fed back to the oscilloscope, you can see a straight line, suddenly turn into a mountain, and you receive a very strong signal! Poor us, we can only use this way of hurting our ears to feel the fruits of radar detection. ”

The commander's words were a kind of summary, and Diana thought them were an encouragement. She stood upright and swore an oath: "Commander, rest assured, no matter what difficulties there are, we will persist in doing a good job!" ”

"Excellent! Now let's take care of it. ”

"Huh?" Diana had thought that the commander had any words of encouragement, but unfortunately it was not.

"The experiment has been successful on the surface, but I now need more objective examples. Now manipulate the remote sensing and activate the automatic rotation of the antenna! ”

"Yes!"
