The former used the normal band frequency, and the time was 10:40, that is, after the phone call with Asahi & Co.

The next one is a high-frequency ground wave frequency, which is at 11 o'clock.

Almost an hour later, after twelve o'clock, the Japanese consulate sent another telegram at its normal frequency.

This telegram took a long time to send, a full twenty minutes, and it was not estimated that it was a telegram sent to Shanghai or the Kwantung Army to inform the details, which is why it was so long.

Is it possible that after receiving the notice from Yoshiaki, Asahi wanted to inform someone of this information, but suddenly the power went out, the radio station could not be used, and the call was afraid of revealing the address and identity of the other party, so it could only ask the Japanese consulate to send a telegram to inform the other party?

And the object of the notification has two dials, one dial can receive and reply to the signal in the normal band, and the other dial can only sprint away from the sending and receiving?

And the normal band is more urgent than the short-distance band?

But the problem is that all night, Qi Zhenjiang did not listen to the message that had been replied.

Not only that, but the search team also found no radio.

If the other party only receives commands and does not need to reply, they will naturally not use the radio.

An ordinary radio with a tube and a slight modification can receive radio signals on most frequencies.

After receiving the signal, it took a minute or two to disassemble the tube, and it was a normal radio again.

Qi Zhenjiang has many such talents under his hands.

However, Fang Buwei still didn't believe that the Japanese spies would suddenly be so poor.

After arresting so many Japanese spies, Fang Buwei has never encountered such a situation.

The standard process of the Japanese spy communication team is simple: send a signal, the other party receives it, and then calls it back.

Even if there is no specific content at the time of the call, a reply instruction will be sent on behalf of the message that has been received.

This is also the reason why Fang Buwei was full of confidence at the beginning of the plan.

The radio station that received the telegram only dared to send out a signal, and it could detect it without doing anything.

Why did the contact procedures between Japanese spy stations suddenly change this time?

Could it be that he was caught too much by himself and suddenly changed his strategy?

Probably not!

Where did the Japanese think that they would be able to locate the station?

It is the first time that I have used the system to dig up a spy by locating the radio station.

I wanted to use it that time, but unfortunately I didn't have points.

There is no need for the Japanese to omit such an important procedure.

Yoshiaki sent a signal, and after the other party received it, he should not not reply.

Fang Buwei knocked on his head.

It must be that I was negligent somewhere!

But all that should have been thought of was that apart from the four telegrams that Yoshiaki had sent before and after, there was indeed no other signal heard......

Wrong!

Fang Buwei was suddenly stunned.

It was like a flash of lightning flashed in my head, and although it was brief, it took care of all the corners......

Who's to say that no other signals are heard?

What about the two newspapers?

"Give me the transcripts of those two newspapers!" Fang Buwei said suddenly, and even his voice was a few points higher.

"What comes to mind?" Gu Zhenlong showed joy fiercely, "I was just asking about the content of the call between Yoshiaki and Asahi Foreign Bank, why did you suddenly get to the newspaper office again?" What does it have to do with these two newspapers? ”

Those who are familiar with Fang Buwei know that when Fang Buwei's calm and mountain-like temperament suddenly disappeared and began to be startled, it means that he thought of a crucial clue and was not far from solving the mystery.

It's been like this every time, and I've never missed a mistake.

Taking advantage of Qi Zhenjiang's efforts to hand over the folder, Fang Buwei quickly explained to Gu Zhenlong: "It was found that there was an airwave signal, and Section Chief Qi found that these two radio stations had been reported in the Radio Administration Bureau according to the call sign at the beginning of the message, and they belonged to these two newspapers.

The radio station was indeed theirs, and it did send telegrams, and they all claimed to be sending a report to the Shanghai headquarters, and the content of the reports was all news reports about the assassination of you and the director of the department......

But why did they send a report to Shanghai so late? It's been seven or eight hours since you were assassinated, so why did they go before that? ”

Gu Zhenlong shook violently.

The press release at three o'clock will be sent at eleven o'clock?

Fang Buwei took the two copies of the newspaper records, glanced at the time, and was immediately overjoyed.

"Commander, look!"

Fang Buwei refers to the time of the report.

Both newspapers did not start sending their reports until a second telegram had been sent by Jimin.

After receiving a report from the Ministry of Foreign Affairs, Ariyoshiaki reported the news to the semi-public and secret espionage organization in Nanjing City 15 minutes later.

There is no doubt that the launch of these two newspapers is Asahi Foreign Bank. There is no direct connection with the Japanese Consulate, and the same code is not used.

Soon after receiving the notice, the power went out in the area, so it could only take the risk of calling and asking Youjimin to notify the subordinate agencies on its behalf.

There is a Jiming to change the frequency and password, and the report will be sent again at 10:40.

After receiving the notice, the two newspapers changed the frequency again and replied to Ariyoshiaki......

The newspaper's radio stations are all registered, and it is normal to send out newspapers.

Moreover, using the identity of a reporter as a cover has always been the most popular and commonly used method used by various secret services.

This is true of the Japanese, this is true of the military commanders after that, this is the case of the central unification, not to mention the underground party.

Even when the Axe Gang stabbed the target, it was the favorite trick to use.

It was the reporter who assassinated Shirakawa Yoshinori, and it was the reporter who assassinated Wang Zhaoming......

The look at the two codes was not compared to the two codes one by one, and no one, including Gu Zhenlong, dared to disturb him.

With a "bang", Fang Buwei smashed a heavy punch on the conference table: "Commander, I found it!" ”

He spread two copies of the code on the table, pointing to one with one hand.

"Commander, Director, look!"

Where Fang Buwei pointed, several identical sets of codes appeared.

"These two newspapers use the same codebook?" Gu Zhenlong asked in surprise.

"Yes!" Fang Buwei nodded heavily, "Although the position is different, one is placed at the beginning and the other is placed in the middle, but at the same time, four consecutive sets of identical codes appear, and they do not appear at once, is it a coincidence?" ”

"It can't be a coincidence!" Qi Zhenjiang replied, "This should be a call sign......

Fang Buwei understood what he meant.

In fact, it is a encrypted verification code used to call the other party.

It is the same as the verification code reported by the public radio station in the Radio Administration, but in these two messages, this set of call signs represents the identity of the consulate radio.

When Yoshiaki saw that there was an encrypted call sign in the copy record, he knew that the other party was calling him.
