Yong Shiquan nodded and asked: "I see you are adjusting the frequency of the radio station. Is it that every time this radio signal appears, it is on a different frequency band?"
"Uncle, this unknown radio signal is exactly what you said.
Another key issue I discovered is that the method of sending this signal feels familiar to me in terms of habits and characteristics.
But I couldn’t remember who sent the message, and I couldn’t identify the person who sent it.”
Quan Jin talked about his research and judgment on this radio signal, and also searched in his mind who might be the person who sent the report.
Quan Jin's discovery is indeed a very critical issue. If we follow this clue, the "true face of Mount Lu" of this mysterious and suspicious radio signal will be revealed.
But Yong Shiquan doesn't want to touch this clue now. The matter is so important that it needs to be discussed in the long run.
At the same time, Yong Shiquan judged that the illegal radio signal that Quan Jin detected, which did not have a fixed frequency band for use, must not have existed for a day or two.
Otherwise, there would not be such frequent sending and receiving, and they must be transmitting important messages.
Unauthorized use without registration by specialized government departments and frequent changes of radio frequency bands to avoid inspection are common manifestations of illegal radio signals.
But Yong Shiquan's experience is so rich. After learning about this radio signal from Yong Shijing, he knew that if he was not completely sure, the second brother would not specifically raise this issue that requires great attention to him in the telegram.
.
According to the code words hidden by Yong Shijing in the telegram, there are several points that must be paid attention to in the radio signal being detected now.
One is that this radio signal has never appeared in other areas before, and it is unfamiliar to the telecommunications personnel of "Yongwangwei".
In other words, had it not been for the "Thunder Sword Operation" launched in Tonglu, and he and Yong Shijing led teams to Tonglu respectively, it is estimated that this mysterious signal would not have been exposed.
The second is that this radio signal is regular. It seems that the transmission time is not fixed, but in fact it closely follows the progress of the commander-in-chief's "Operation Thunder Sword" for communication.
The occurrence of suspicious radio signals was first detected by Yong Shijing's radio station in the city, and then notified to Yong Shiquan outside the city.
After that, the two radio stations conducted cross searches and found that every time the general guard made radio contact with Yong Shijing and Yong Shiquan, this radio signal would appear within half an hour at most.
After the radio contact between Yong Shijing and Yong Shiquan, this radio signal will appear for up to ten minutes.
Such targeted radio contact makes one unable to help but guess the purpose behind it.
Thirdly, this radio signal will appear in three frequency bands. In the commercial radio frequency band where it is easiest to conceal oneself, although it does appear, it does not occur often.
On the contrary, it appears more frequently in two remote frequency bands that are rarely used by units.
Moreover, the difference between telegraph exchanges between the General Guard and different subordinates in Tonglu is very obvious compared to radio communication on different frequency bands.
Fourthly, if you compare this radio signal with the current No. 1 contact code and No. 2 action code of the "Yongwang Guard", they are very similar in terms of the composition of the code combination and the principle of setting the code.
of.
It can be clearly judged that this radio signal and the two sets of radio communication codes used by the "Yongwang Guard" came from the same family.
With the above characteristics, this radio signal suddenly stands out among many illegal signals.
This shows that in the Tonglu area, I don’t know when it started, let’s just say it was recently, there was a force targeting the “Yongwang Guard” in close contact.
Regardless of whether the core force of this force is out in the field or hidden in Tonglu, clues have been revealed in the "Operation Thunder Sword" led by Yong Ming.
And this situation simply has more advantages than disadvantages for "Operation Thunder Sword".
In the short term, it will affect and hinder the advancement of actions, but in the long term, it eliminates a huge potential risk.
So why is it purely for "Operation Thunder Sword"?
This is relative to "Yong Wangwei", or to be precise, it is different from Yong Ming.
Because "Yongwangwei" is Yongming, and Yongming is "Yongwangwei".
This is the basic tenet set by the "Yongwang Guard" since its establishment. From the first generation of chief envoy Yong Haixin to today's Yong Ming, they all follow the principle of "when the chief envoy is there, the 'Yongwang Guard' will exist; if the chief envoy is there, the 'Yongwang Guard' will exist;
If there is no such thing, "Yong Wangwei" will perish." This is the holy saying of Emperor Renzong of the Song Dynasty.
This is also the reason why Yong Shijing became deeply worried after discovering the existence of a mysterious force with unknown background and origin in Tonglu that clearly had a conspiracy against the "Yongwang Guards".
Now, after receiving direct evidence of the existence of this hostile force, Yong Shiquan has fallen into the same worries as Yong Shijing.
In order not to arouse people's confusion, Yong Shiquan said in a relaxed tone: "The principles based on this radio communication are from the same origin. Although there are ever-changing shapes on the outside, the essence is the same and similar.
Although his reporting methods differ significantly due to personal habits, it is common for one or two similar situations to occur.
Quan Jin, I remember that you were a first-term student of the telecommunications training class run by Wei Li, right?"
"What my uncle said is that I was lucky enough to be selected into the first batch of telecommunications training classes. At that time, one of the teachers who taught us was a young master!
After our first batch of students graduated, in the following three training classes, the students did not have the kind of treatment that a young master would teach them specifically.
To this day, my fellow students still regret it when talking about their learning experience!"
When asked by his great-uncle, Quan Jin immediately answered with some pride.
"Well! Are you familiar with the situation of these classmates and junior students of yours?"
"Uncle, how can I be familiar with everyone here? I'm just familiar with the people close to me. Those who are far away from me don't know much about their situation."
Quan Jin shook his head and answered without even thinking about it.
"Then don't bother thinking about the transmission method of this radio signal. You only need to make a record of the interception for verification. That's the business.
Turn the radio station back to our fixed frequency band and be on duty. There will be important situations to report to the clan leader tonight, so don’t be distracted."
Yong Shiquan ordered.
"Uncle, I have recorded the contents of the radio signals I heard. I will add other information and it will be used as verification data."
Seeing Yong Shiquan nodding his head after listening to his words, Quan Jin asked: "Will we still monitor this signal later?"
