Secret War Silent

Having access to the radio, Kinoshita started his plan to modify the radio station. He took the boss's radio out for a while, dismantled it, and brought it back, saying that it was sent out for repairs.

The boss didn't doubt it either. After all, the radio is very expensive, and most people don't have it. It's normal to repair it for ten and a half months.

……

"Qin Group, that, that..." Luo Yao was seriously studying the algorithm of the Japanese army's new secret code in his study.

Suddenly a person hurried in without knocking on the door, stammering.

Luo Yao looked up and saw that it was Zhao Shiyin.

"Don't worry, just speak slowly." Zhao Shiyin was appointed as Chen Zerong's deputy, assisting Chen Zerong in charge of the radio team.

And Xu Jihong temporarily replaced Yi Xuezhong's work and was responsible for the security work of the 'X' group in Yangyuan.

And Deng Yi (Ma Huan) was wounded in the battle on Rongyuan 4. Although he was only bitten by a bullet, it was not serious, but he is still recuperating.

"That signal appeared again." Zhao Shiyin stroked his chest and calmed down a little.

Luo Yao immediately understood what signal Zhao Shiyin was talking about.

"Where?"

"It's in Xiangcheng, I can feel its existence." Zhao Shiyin said.

"Go, take me to listen."

"This signal..." Luo Yao put on the earphones and listened carefully for a while, then frowned slightly.

"It should not be a standard radio station. Even if the current of a standard radio station is unstable, there will be no such sharp sound." Zhao Shiyin said.

"It's self-made, and the button material is not good enough. He is right in the technique. It seems that our speculation is correct. He should still be in the city and not leave." Luo Yao nodded.

"Can you track this signal?"

"If there is enough time, it should be possible." The technician who complexly manipulated the radio's direction-finding instrument replied.

"Determine its approximate location." Luo Yao ordered.

"Yes."

……

Inform the insider to participate in the case analysis meeting.

"It is now confirmed that this Kinoshita Zhishui is in Xiangcheng. We have set up checkpoints at various traffic arteries leaving Xiangcheng. Now it is very difficult for anyone whose identity is unknown to leave Xiangcheng."

"Brother, if Kinoshita and Keiichi Kondo are together, then for us, the goal will be bigger." Li Fu nodded.

"On the contrary, I think that he was not with Keiichi Kondo. First of all, we have no relevant information from the statement of the captured Japanese agent. Kinoshita was with Toshi Fujita and others, and Keiichi Kondo spent a lot of time with them. It's not long, Kinoshita left alone, there must be a way to contact Fujita Jun, but now we have cut off his contact with Fujita Jun, he is alone, and it may be more difficult than us to find Keiichi Kondo." Luo Yaodao, "From this signal, it can be seen that he is trying to contact Jiangcheng's secret service, because all the signals he sends out are repeated, and this is a typical distress signal."

"Qin Group's analysis is correct. If this is a distress signal, then Kinoshita Yumizu is probably the only one. Kondo Keiichi should not make such a move. It will only expose himself faster and make him We confirmed that he is still in Xiangcheng." Xu Jihong said.

"Could it be done on purpose?" Deng Yi also attended the meeting with injuries.

"I don't think so. Kinoshita Yumizu's identity is very special. Keiichi Kondo dare not betray him to protect himself." Li Fu said.

"Assuming they're not together, or haven't been in contact yet, is it a good opportunity for us?" Luo Yao asked.

"Qin group, what do you want to do?"

"If this is a distress signal, then he will definitely continue to broadcast it repeatedly. For us, we can find his location through the radio positioning and direction finder." Luo Yao said.

"Kinoshita Yumizu is an expert in encrypted code communication. He doesn't know that continuous broadcasting will expose himself?"

"He knows, but he may take risks, because we have the frequency and call he is using now, and the Japanese side also knows that Fujita Toshi has been arrested and Kondo Keiichi is missing. Therefore, the signal sent by this frequency, even if they Even if it is received, it may not be believed, so Kinoshita Zhishui must show his identity through repeated broadcasts."

"Kondo Keiichi had the experience of being cheated once, this time..."

"Now the person in charge of Kondo's office in Jiangcheng is his deputy, Major Asami. We don't know much about this person, so it's hard to make a judgment on his choice. But in the past, when Keiichi Kondo was in office, he was a very transparent person. People." Luo Yao said, intelligence work always comes first, and Kondo Keichi was trapped in Xiangcheng by himself, so he naturally wanted to know about the temporary head of Kondo's agency in Jiangcheng.

"Shall we greet stationmaster Li this time?"

"It's not too late to find out the person first, and then notify him." Luo Yao said, "Our current actions are all based on inferences, and there is no real evidence."

"clear."

"Li Fu, you are in charge of the communication with Li Haihuai, keep the information flowing, especially if Fujita Jun opens his mouth to explain something, you must tell me immediately." Luo Yao began to assign tasks.

"Yes."

"Xu Jihong, you are also a communication expert. I will leave the task of finding the radio signal to you. Determine the location of the person and the radio station. Don't arrest him yet." Luo Yao instructed Xu Jihong again.

"Yes." A joyful smile appeared on Xu Jihong's face, he finally had the chance to show his talents, and he almost died of aggrieved lurking in Jiangcheng.

Chapter 0463 This guy is worth money!

"Qin Group, that signal is back!" Zhao Shiyin, who was staring at the signal, rushed into the dining room during dinner.

"Notify Hu Yanran (Xu Jihong), hurry up and locate..." Luo Yao ordered quickly.

I didn't eat any food.

Luo Yao and Zhao Shiyin came directly to the radio room.

Anyway, this signal should not last for too long, and it doesn't matter if you play for a while before eating.

"It's still the same signal. The signal strength is obviously much better, and the technique is clearer. He should have improved the radio. This is really a talent. He can compete with Xueren..." Luo Yao put the earphones directly to his ears While listening, he commented.

"Qin Group, the call sign has not changed, but the content has changed. We don't have a code book, so we can't decipher it for now!"

"Don't worry about him, just wait for news from Hu Yanran now, I hope she can seize these few minutes."

At this moment, there is no curfew in Xiangcheng, and there are still many people walking on the street, but most of them are preparing to go home, or are already on their way home.

After the victory in the Battle of Xiangcheng, and the celebration of the "Double Ten" festival a while ago, the time limit was relaxed. Now the curfew time has also been extended by two hours, and the streets will not be cleared until eight o'clock.

A radio direction-finding vehicle converted from a truck drove out from a hidden location immediately after detecting the appearance of the signal.

In good conscience, the radio direction finding equipment eliminated by the British is still good, and Xiangcheng is not as big as Shancheng and Jinghai.

In those cities, there are too many active radio stations, government departments, private ones, and various underground latent intelligence stations...

That is too difficult to monitor.

In comparison, the radio waves over Xiangcheng are relatively sparse, easy to monitor, and less disturbed.

Then the effect is also good.

Because of the limited opportunities, this time Luo Yao asked Xu Jihong to use the method of "crossing fixed points" to determine the location of the station.

In addition to Xu Jihong's radio direction-finding vehicle following the car, there are two other people carrying portable radio direction-finding instruments on their backs, which are used to perform direction-finding at the same time when the radio station transmits signals in three directions.

The point or area where the three lines intersect is where the station is hiding, which is a quick way to pinpoint the station's location.

Because the calling frequency of the right radio station is already known, this saves the time of searching for the signal and locks the frequency directly.

Then operate according to the direction finder.

This time the signal lasted about 8 minutes, which was nearly 3 minutes longer than the last time. Obviously, the person who broadcast the signal also wanted to take the risk of getting in touch through the call with added time.

"Qin group, the signal is gone, it should be cut off actively, a total of ten consecutive calls, each time around 40 seconds, this guy's timing is very precise." Chen Zerong Hui reported.

"Group leader Hu reported that when the signal disappeared, she was located near Bajiaoting Street." A radio operator reported.

"Where are the other two?"

"One is in Tiandeng Alley, and the other is near Bagua Alley!" Soon, the positions of the other two people came back.

Luo Yao easily marked the location of the three people on the map of Xiangcheng.

These three points exactly correspond to a triangular area.

"Notify Hu Yanran, go back to the base first, and wait for his next broadcast. I guess his next broadcast will be around four or five o'clock in the morning tomorrow." It was carefully calculated. Although it is conducive to the transmission of electromagnetic signals at night, it is also easy to be captured by monitoring. Therefore, he chose to broadcast it quickly while eating. This is a smart man.

Decided to go tomorrow.

……

"Get up and go to Xiangcheng with me." At three o'clock in the morning, Li Fu was sleeping soundly, but Luo Yao pulled him up from the bed, Chen Zerong was on duty, so Li Fu slept alone.

Otherwise, Luo Yao wouldn't be able to break into the couple's room.

"Brother, what time is it..." Li Fu obviously didn't wake up, so he became afraid unwillingly, looked at his watch, it was only less than three o'clock, and complained even more.

"I'll give you 5 minutes to wash up, hurry up, I have a task!" Luo Yao gave him no time to complain, and ordered directly.

Li Fu suddenly became excited, opened his eyes, and moved his hands quickly.

"you drive."

"Just the two of us?" Li Fu was stunned. He thought that Luo Yao would bring at least seven or eight people with him, but when he looked down, it was just him and Luo Yao.

"What's the matter, Fujita Shunto's special agent team has been arrested, what are you afraid of?" Luo Yao asked back.

"It's not that I'm afraid, but the two of us are too monotonous, why don't we call someone else?" Li Fu said.

"Are you going?"

"Let's go, let's go, can't I go?" Li Fu got into the car, started the car and drove out of Yang Garden.

……

After more than an hour, Luo Yao and Li Fu drove to the temporary monitor where Xu Jihong was.

Because of a special pass from the theater command, they could enter the city before dawn.

"The Qin group is here?"

"Didn't you rest?" Seeing that Xu Jihong was fully dressed, Luo Yao asked in surprise.

"I've already slept through. Their first half of the night and my second half of the night." Xu Jihong explained, "Why are you here?"

"There are only three things to do, this is probably the only chance we can catch him, so I must come." Luo Yao said.

Although the other party may not be an experienced agent, he has also undergone such training. It should be known that sending a telegram in an enemy area is very dangerous. Once detected, it will be exposed.

Generally, in one location, the number and time of sending telegrams are limited. Of course, in many cases, the intelligence team will set up guard posts, especially when sending telegrams.

For a lone traveler like Kinoshita Zhishui, if he wants to ensure safety, he has to constantly change the location of the report.

No matter what he will do, everything must be considered in the worst direction.

"If you come, this person probably won't be able to escape today." Xu Jihong said happily, she had fought side by side with Luo Yao in Jiangcheng, and knew some secrets about Luo Yao's cracking of the "ghost radio station".

Luo Yao's abnormal hearing was even more impressive among the first batch of temporary training students. Although it is rare to hear that he has made achievements in this area, everyone who knows knows that he is now in a high position. Most of the time, he doesn't need to end in person.

"Don't flatter me, it depends on whether he will broadcast it today." Luo Yao said with a slight twitch of his mouth.

"It should be. Once this kind of telegram for help is interrupted, it will arouse suspicion." Xu Jihong said.

"I hope so."

In the "anti-espionage" work, any accident is possible. In many cases, investing a lot of manpower and material resources may not necessarily yield results.

It's not an easy job to do.

"It's half an hour to six o'clock, order them to leave, and we can get ready." Luo Yao looked at his watch.

"Yes."

Starting from the position detected yesterday, once a signal comes in, it can save a lot of time. The time for the spy to "broadcast" is limited.

Luo Yao's guess of the "broadcast" at this time was also an inference based on the first time this signal appeared.

The other party should also consider the receiver of this signal, so they should also receive it at this time.

Because if the time has no rules, if the other party misses the time, how can they receive this message?

Of course, he can also agree on the next "broadcast" time in the telegram, so he can only gamble.

Luo Yao and Li Fu boarded Xu Jihong's radio direction-finding vehicle. The modified direction-finding vehicle was actually very spacious inside, and it was covered with a layer of rain cloth. It was impossible to see what was inside. Of course, the antenna on the car would inevitably be exposed to the outside. of.

No way, if you don't do this, how can you receive the signal?

In fact, this car has been modified for a long time. I didn't plan to use it at first, but I was prepared for it. In the end, I didn't expect it to be used.

The equipment on the car was bought by Luo Yao from the British at a "super low price". For them, after the equipment is scrapped, it is no different from scrap iron. When it is sold to the Chinese, it is at least better than before scrap iron.

And if you just fill in more losses on the report, the money for the equipment will fall directly into your pocket.

What a good business, the British are not stupid, why can't this business be done, it's nothing more than safety and insecurity.

"Qin Group, there is a signal!" Before the direction-finding vehicle arrived at the position last night, the signal indicator light came on.

"You guys stay in the car, go to the front and put me down directly." Luo Yao ordered.
