Eastern suburbs of Tanglin City.

"I'll rub!" Gu Feng, who was checking in, took off the headphones and cursed.

"Crazy, what's wrong?" Sun Kai asked strangely. Wang Dalei and Wu Chengli, who were busy next to them, also showed surprised looks.

"The background noise has increased several times, it must be the group of Sun ...... at the monitoring station Those people are sending interference signals again! Gu Feng originally wanted to scold those people as "grandsons", but he suddenly reacted that Wu Chengli's father was the head of the monitoring station, so he quickly changed his words.

Gu Feng is an old ham in Tanglin City, and he has participated in various international competitions many times, and he has very rich competition experience. Basically, the members of the amateur radio club in Tanglin City were brought up by him, and it can be said that without him, the club would not be able to function at all.

Therefore, Gu Feng is also very clear about the interference equipment in Tanglin City. These two devices were also put together a few years ago, when he was also participating in an international amateur radio competition, and it was in SSB voice mode, but because he did not have any preparation, as soon as the jamming equipment of the monitoring station was turned on, he was directly blinded in both eyes. At that time, he couldn't receive any signal immediately, and as a result, the game couldn't go on at all, and he thought that his radio station was broken.

Later, I learned that it turned out to be the group of people from the radio monitoring station of Tanglin City who invented a radio jamming device, and every time this kind of moment, it emits a huge amount of interference signals to the outside world, and the slightly weaker signal can't get in or out at all, resulting in the entire Tanglin City as if it has entered the electromagnetic shielding area, and the ham of the entire Tanglin City has not reached this moment to scold the mother, but there is nothing to be done.

Since there is no way to avoid it, you can only seek another breakthrough by yourself. The hams just have a spirit of not admitting defeat and being willing to study. The hams in Tanglin City can only rely on their own technology to break through the "electromagnetic shielding", and after such a long time, they have accumulated a lot of experience in electromagnetic confrontation.

Scolding and scolding, the game still has to go on. And they also made some preparations for breaking through the electromagnetic blockade this time, so Wang Dalei ran outside and began to adjust the direction of the antenna, and Gu Feng began to adjust some basic parameters of the sky adjustment.

……

A residential community in Tanglin City.

"Damn, it's here again!"

Listening to the rustling sound in the headphones, a long-haired young man muttered, then ran to the rooftop and began to adjust the direction of the Yagi antenna he had set up.

At this stall, someone behind him suddenly shouted: "Stop! What are you doing? ”

The long-haired young man was shocked suddenly, and when he looked back, he saw several aunts with red sleeves on their arms and two tall security guards standing behind him, looking at him with a serious face, and his eyes revealed a very obvious look of excitement.

The long-haired young man explained, "That'...... I'm adjusting the antenna. ”

Several aunts surrounded him without saying anything, looking him up and down.

"Young man, we are from the neighborhood committee, what is your name, why do you look so fresh?"

"My name is Wang Jiahua, and I just moved here." The long-haired young man answered truthfully.

"Someone reported that you were engaged in spy activities, and you honestly confessed, is this the radio antenna you used to communicate with the spies?" One of the fat aunts shouted.

"Uh......" The long-haired young man was stunned, and only then did he see that the tall security guard was blocking the door of the rooftop at this moment, intentionally or unintentionally, as if he was afraid of his escape.

He understood a little, and couldn't help but laugh and said: "Don't get me wrong, I'm a new technician from Lujiang Electric Porcelain Factory, how can I be a spy?" If you don't believe me, you can go to Ludian and check it out. ”

"You're still quibbling!" The fat aunt didn't give up, she pointed to the antenna on the rooftop and said, "What is this?" That's your evidence of the signal. Let's go and search your room, and when the time comes, everyone will be stolen, and see if you are still a dead duck! ”

In the room of the long-haired young man, there were some strange electronic devices, and if Ham saw them, he would definitely know that these devices were a complete set of radio stations. Although several aunts in the neighborhood committee don't understand this, they can also see some signs from their appearance. They have long seen similar footage from TV.

The poor long-haired young man explained to the aunts of the neighborhood committee for a long time, and finally showed them his student ID, but he still failed to gain their trust. Later, a policeman came, but fortunately the policeman had heard about ham, so he was not taken to the police station for interrogation as an enemy.

This is happening across the country, and the lack of awareness of amateur radio has led to a variety of difficulties and challenges for Chinese hams, but this has not stopped their love for radio.

After the electromagnetic shielding in Tanglin City appeared, Lin Hong also noticed it for the first time.

He also specially removed the filter he had made, tested it, and found that the radio signal was very poor at the moment, but he didn't know what the reason was, but only speculated that there must be several very powerful interference sources in Tanglin City.

Fortunately, he has an "adaptive signal filter" in his hand, which is small, but it happens to be the nemesis of these interference signals, filtering all those ineffective interference signals, and the signal he receives is basically between "58" or "59". It's just that the signals sent out have been affected to a certain extent, but fortunately, these signals are in CW mode, and the impact is minimized.

Time passed quickly, and when others had already changed a wave of check-in staff, Lin Hong was still tirelessly communicating with others, fast and accurate. He completely forgot the time, and the communication log paper next to him became more and more, gradually spreading all over the ground.

It wasn't until about three o'clock in the afternoon, when his stomach growled, that he remembered that he didn't seem to have eaten lunch yet. At this time, the radio signal gradually thinned, and the communication effect was not very good, so Lin Hong stood up, moved his somewhat stiff body, and came to the workbench to gobble up the lunch he brought.

After having been highly concentrated for so long, Lin Hong felt that his brain was also a little dizzy, and after eating, he did not immediately start to continue the game, but switched the communication mode to SSB mode, and he wanted to listen to the evaluation of other hams on the radio.

Sure enough, today's amateur band is really very lively, at least several times more lively than before, and everyone is talking about this cqww_dx competition on the channel. Most people are just starting out, and they don't know that such a competition exists in the original world of ham.

Lin Hong listened for a while, but didn't hear any useful information, maybe the masters are actively preparing for the game, now at this time, they are either still checking in, or they are resting and sleeping, where is the waste of time running here to chat?

Just when he wanted to switch back to CW mode, he heard someone calling him on the channel, and this person was none other than his American ham friend W5AUN little girl.
