The contact that came from the other day was not smooth. Fan Keqin was worried that always using the same line as before would lead to accidents, so he spent a whole morning carrying out the "line-strapping" activity in the city again and searched for a long time.
However, I did not encounter any phone lines that opened long-distance services twice in a row. It was not until noon, after lunch, that Fan Keqin found another line.
Maybe it was a bad morning, but by the time he finished the phone call, things finally turned around.
The first one was that Qian Jinxun told him to keep his phone on at all times. Of course, this was said in code. Turning on means that the spy transmitter turns on on time. In addition, there is a radio frequency.
These two pieces of information were told to Fan Keqin, who immediately understood that this had a deeper meaning: the headquarters had discovered the movements of the Little Japanese fleet, and indeed according to Fan Keqin's previous analysis, the other party began to move along Cruising offshore.
Starting from time, Qian Jinxun and Sun Guoxin in Chongqing, as well as the leader of the analysis team of the Investigation Department, comprehensively analyzed the situation and reviewed a large number of intercepted messages that showed: At that time, the seaplane carrier The fleet suddenly turned around after receiving an order from the Japanese Navy Department.
Because the national radio station is also trying to intercept Japanese radio information at all times. The principle of the radio thing is radio. As long as the frequency is right and within the range, the probability of interception is very high. The main thing is whether it can be deciphered.
This is also the reason why Fan Keqin seized the Japanese code book at that time, which directly attracted the great attention of Sun Guoxin and Boss Dai. In other words, both sides can intercept a large number of each other's telegrams. But whoever can decipher the encrypted code more quickly will have an advantage.
The little devil's intelligence department was among the earliest in Asia and even the world in terms of establishment time. Therefore, when the all-out war of resistance broke out, this advantage accumulated over time was extremely huge. Later, after Fan Keqin cracked down on Japanese spy groups one after another and seized a large number of Japanese radio stations and code books, Chinese deciphering experts finally found some rules for encrypting Japanese telegrams.
It can be said that China’s intelligence agencies did a very good job in deciphering the Pearl Harbor incident. Although the Americans did not take it seriously, they did pay a heavy price later. The Pearl Harbor fleet was directly disabled by the little devils.
From this point, it can be proved that in the past, although the speed and efficiency of telegram deciphering were still lagging behind the little devils as a whole, it was no longer the previous situation where they could only be passively beaten. At least he can fight back. This is a big step forward.
This is even more true now. Although it is still not possible to completely decipher the little devil's message, part of it can indeed be intercepted and deciphered.
After reviewing a large number of intelligence records, the Security Bureau and the Intelligence Division finally discovered some secrets within three days. Because from the intercepted frequencies, after a lot of calculations, it was discovered that in the South China Sea, the base camp of Little Japan, and Taiwan, several radio wave exchanges did occur during that period. Although the specific content was not deciphered, it can be seen through the analysis of telecommunications experts After a lot of calculations, it can be concluded that the signal at one of the frequencies is indeed moving.
After passing the observation post's final discovery and location calculation, we knew that these telegraph signals that were exchanged must be the Japanese fleet, base camp, and Taiwan Island.
So this information is useless? If you really ask that, you can only say... every other line is like a mountain. First of all, this is a three-party communication. Who started first and who started second. Knowing this, you can deduce where exactly something happened. The most important point is that based on this, the Security Bureau and the Intelligence Department once again reviewed a large number of intercepted telegram signals, and finally determined that the sudden U-turn of the fleet was not because of what the little devil discovered, but because of something else. Case.
It can be determined that Fan Keqin's overall plan has not been exposed. This is very critical. Otherwise, the action made by the Little Japanese Fleet would not have been just a communication between the base camp, the fleet, and the three parties across the Taiwan Strait. There must be a suggestion. But no matter how you look at it now, the initiator is the Taiwan Strait. But not elsewhere, so Fan Keqin's plan can still continue.
Fan Keqin returned to the observation room, explained the matter to Zhuang Xiaoman, and finally said: "But from today on, turning on the computer on time at seven o'clock every night will increase a certain degree of danger for us. It must be Just make preparations.”
Zhuang Xiaoman frowned and said: "Guangzhou probably doesn't have the kind of detection equipment in the north. Then I will change a room every day and do the receiving work. In this way, it will always be moving. Even if the other party notices it, there should be no problem. .”
Fan Keqin waved his hand and said: "Don't be careless. If you do this and the investigator is me, you will definitely not be able to escape. Even if I didn't notice you the first few times, after you received a few telegrams, I I just discovered it. I will first ask experts to measure a certain range. In addition, your position keeps moving, but the area is still within the city, so I can judge that you must have many safe places to stay."
At this point, Fan Keqin lit a cigarette and continued: "What does this mean? Even if an agent has the cooperation of a team, will he really send reports in rotation to each lurking person's home? This is impossible. So. You must have a lot of empty houses, safe empty houses. When I come to this conclusion, I will send a large number of agents, or police, to thoroughly investigate the density of empty houses in the city. At the frequency of your movement , range, and finally lock this area."
"After all, we have only identified a number of safe houses near Zhanlan Street. I believe that there will not be too many safe houses in the city that meet this condition. In the end, I will send people to control several suspicious locations and then arrange One or several mobile forces will immediately cut off the power in the area when your next reception signal lights up. In just a few seconds, I will know which area you are in..."
Before Fan Keqin could finish speaking, Zhuang Xiaoman felt a chill in his back. Although Fan Keqin was not so specific. However, everything is very maneuverable step by step. So Zhuang Xiaoman said: "Then... what should we do?"
At this time, Fan Keqin was happy and said: "As I said before, if it is me who is checking you, it will be very dangerous for you to do this..."
