Lin Jiangbei removed the cotton sheets on the bed of Araki Dajing, tore them into two from the middle, and then connected the two sheets together and twisted them into a strong cloth rope, and then tried the strength of this cloth rope with Liu Xuan, and after making sure that there was no problem with this cloth rope carrying his own weight, Lin Jiangbei handed over this cloth rope to Liu Xuan.

Liu Xuan tied the cloth rope around his waist, and then, like a raccoon cat, he easily climbed out of the window of room 413, his fingers picked at the crack in the wall, rubbed it a few times, and climbed to the top of the building.

Then he climbed to the top of the building and hung the rope from the roof to the window opening of room 413. Lin Jiangbei stepped on the window sill, grabbed the cloth rope with his hands, kicked the outer wall of the apartment building with his feet, rubbed a few times, and climbed to the top of the fifth floor.

Liu Xuan waited for Lin Jiangbei to climb to the top of the building, put the cloth rope aside, pulled Lin Jiangbei lightly to a thick clothes pole more than ten meters away, and pointed to Lin Jiangbei in a low voice: "Stationmaster Lin, this is the antenna of room 507, you see, there is a line here, and one leads to room 507 on the fifth floor." ”

Lin Jiangbei took out a small flashlight from his pocket, covered the lamp with his clothes, and carefully inspected the clothes pole with the faint light, then nodded, and said to Liu Xuan in a low voice: "It seems that it is consistent with our previous judgment, Room 507 not only has a radio jammer, but also a wireless telegraph machine. When this antenna is engaged in radio interference, this half can be used as a radio interference suppression antenna. You see this is its plug, cover, connector, antenna element, base, flange and bottom tube ......"

Lin Jiangbei pointed to the components on the antenna and introduced Liu Xuan: "Look here, the other end of the base separates a strand and connects with this half of the clothes pole. This half of the antenna element is actually the antenna of a wireless telegraph that transmits and receives radio signals. The shut-off and on-off between these two antennas is controlled by a switch on this flange......"

"Stationmaster Lin, I really didn't expect that you are so proficient in radio, and I can't complain that Instructor Zhang Huanian Zhang wants to give you the task of detecting Japanese radio jamming stations!"

After Liu Xuan listened to Lin Jiangbei's explanation, he admired Lin Jiangbei even more. When he was the deputy station manager of Henan Station, he also listened to the radio operator in Henan Station explain some knowledge of wireless telegraphy and understood some basic principles of radio reception and transmission. But if it is like Lin Jiangbei who can understand the name and function of each component on the antenna in detail, Liu Xuan believes that not to mention himself, even if he is replaced by a radio operator from Henan Station, he may be confused.

"Actually, there is nothing, if you suffer a loss, you will suffer if you don't attend the Hangzhou training class, otherwise you will naturally understand these things if you follow the telecommunications class to listen to a few more classes." Lin Jiangbei waved his hand and said to Liu Xuan: "Of course, the antennas of ordinary radio transceivers are not so complicated, and some are even just a copper wire, which can send and receive radio signals. And because this antenna involves a high-power radio jammer, the components are relatively complicated. ”

"But no matter how complicated it is, if we just want to destroy it and stop it from working, the easiest way is to cut the wire connected to the antenna with a knife."

After saying this, Lin Jiangbei waved his hand at Liu Xuan, and the two of them walked lightly to the top of room 507, and looked at the window of room 507 to watch.

Although a thick curtain was installed in the window of room 507 to cover it tightly, directly above the curtain, a very small gap was exposed, and a trace of orange light leaked out of this gap.

So Lin Jiangbei made another gesture at Liu Xuan, and the two of them leaned over and climbed on the roof of the building again, keeping their ears close to the floor, listening to the movements in room 507.

Lin Jiangbei heard all the pain in his ears, and he couldn't hear any movement in room 507. At this time, Lin Jiangbei missed Zhao Xiaohu very much, if Zhao Xiaohu followed him at this moment, he would definitely be able to hear the movements in room 507 clearly.

"Lao Liu, did you hear any movement in room 507?" Lin Jiangbei asked in a low voice Liu Xuandao, who was listening hard to the movement against the floor.

"I faintly heard a buzzing sound, but I couldn't hear anything else." Liu Xuan leaned against the floor slab and replied in a low voice.

"Buzzing sounds?" Lin Jiangbei pondered for a moment and said: "The power of the radio transceiver is very small, and it will not make a buzzing vibration sound when it works. Only when a high-power radio jammer is operating, it emits a buzzing vibration sound. ”

Speaking of this, Lin Yuan raised his hand and looked at his watch, and then continued: "Well, at this time, it is the time for Japan's secret radio stations in Shanghai to send reports in a centralized manner, in order to protect these radio stations from being monitored by our radio technicians, Japan's radio jamming machines will start working at this time, sending out suppressed jamming signals. So the buzz you hear must indicate that Tanimura Natsukawa is operating a high-power radio jammer in room 507 at this time. ”

"Then we're going to cut the wires now and bring up Tanimura Natsukawa?" Liu Xuan asked.

Lin Jiangbei pondered for a moment and said to Liu Xuan: "As long as the sub-line of the jammer is cut, don't move the sub-line of the transceiver." In this way, when Tanimura Natsukawa checked the cause of the fault below, he quickly understood that the antenna part on the roof of the building was faulty. ”

"Understood!" Liu Xuan responded, returned to the antenna lightly, took out the blade, and according to Lin Jiangbei's instructions, found the branch line connected to the antenna of the jammer on the base, and used everything hard, and the line was immediately broken into two.

After doing this, he followed Lin Jiangbei and the two of them to the roof passage, hid his figure, and waited for Tanimura Xia Chuan to come up.

Sure enough, within a few minutes, I heard a sound of footsteps downstairs, and then I heard only a creaking, and the door of the roof passage was pushed open, and a man came out with a flashlight and muttered.

After making sure that there was no one else behind Tanimura Natsukawa, Lin Jiangbei and Liu Xuan pounced out like two leopards, and before Tanimura Natsukawa could react, his mouth was covered by Liu Xuan's palm, and then Lin Jiangbei's hands were already stuck in his head and twisted hard, so Tanimura Natsukawa followed in the footsteps of Araki Oi and went to see their Amaterasu in the same way......
