Chapter 72: Wireless

What kind of blow is it that Xiao Lin has always thought that her father is in "Eden" and can be reunited with him if she waits patiently, but now she is suddenly told that this place on the radio does not exist?

In fact, the same is true for me, although I have not been in contact with my relatives like Xiao Lin, but I also believe that my family will wait for me in a safe place. So I reluctantly asked, "How can you be sure it's a signal from the city's radio station?" ”

"Have you ever heard of radio 'Fox Hunting'?" Lu Feng asked.

"Radio 'Fox Hunt'?"

He nodded: "It is a relatively niche sport, placing an unknown number of radio signal sources in the wilderness, and the contestants hold a radio direction finder, measure the direction of the 'fox (signal source)' by listening to the signal, and quickly catch the fox, this sport is radio fox hunting......"

At this time, the madman slapped his thigh and said, "My brother was the champion of the National Youth Radio Direction Finding Championship!" ”

"That's right," said Lu Feng, "your brother is a master at capturing ethereal radio signals in the air, and he deduced that the location of the radio station was not far away, it existed somewhere in the city. ”

Tianliao pushed his glasses complacently and coughed lightly: "This is nothing, the entire sky is only this signal, compared to the previous sky, the sky was full of interference signals, which is much more difficult." ”

"You mean...... You can guess the location of the transmitter by listening to the radio? Xiao Lin asked incredulously.

I saw him take out a radio, no, it wasn't a radio, just a circuit board full of electronic components, with a long antenna sticking out of the end, and a headphone plugged in underneath.

"Fortunately, I found a soldering iron and solder on the repair table of the mobile phone store, and I disassembled several radios and used 15 resistors, 20 capacitors, 3 diodes, 3 transistors and 2 inductance coils to make this manual direction finder.

He continued: "Fortunately, I have studied the production method and principle of the direction finder, and I remember the color distinction of the resistor, and the size of the capacitor is not wrong, as well as VD1 detection, VD2 varactory, NPN type and PNP type, T1, T2 ......."

Speaking of which later his words almost became a curse, the madman hurriedly said: "Brother, stop, stop, now is not the time to show off your skills, let's talk about the point!" ”

Lu Feng spread out a crumpled map on the table and said, "Let me explain!" ”

He picked up the pen and drew a circle on it: "This is where we are." Then another circle was drawn next to the point: "During the time you were away, we came to the roof of this building about two kilometers away......

"Tianliao can find the large sound surface and dumb point of the wireless signal by listening to the volume in the direction finder, this explanation is too professional, in short, it can measure the general direction of the radio station, and then ...... like this"

He extended a straight line from each of the two circles, "Since the radio travels in a straight line, the direction of the radio station is heard from a distance of two kilometers, and then the two straight lines intersect, and the intersection is the position of the station!" ”

Where the two lines converge is the northeastern part of Pegasus City.

"But radio direction finding is not accurate positioning, no matter how professional direction finding athletes will have deviations, and a little deviation will cause a fallacy of several kilometers, excluding these effects, we finally set the area in this range, the possibility of a radio station here is quite large!"

He extended two more straight lines from the two circles, intersecting at a point farther away, and the result that the four straight lines intersected into a square, which he painted with diagonal lines.

Tianliao said: "After calculation, the nearest straight-line distance is about 15 kilometers, but the farthest is 25 kilometers, which is a considerable range. ”

I looked at the map and suddenly noticed something, so I pointed to the shaded part and said, "Isn't that the ......?"

Lu Feng said with a smile: "That's right, Pegasus City People's Radio, there is the most likely suspicious signal source!" ”

Xiao Lin sat next to me, looking at the map in amazement, she must have understood the explanation, knowing that the so-called "Eden" on the radio was not really Eden, so what was the place in her father's mouth?

I gently held her cold little hand and said to Lu Feng, "Is it possible that it is just a turntable there, and the real information is actually coming from somewhere else?" ”

Lu Feng pondered: "It's not that this possibility is impossible. But in any case, the transfer station needs to be operated by someone, and we can only find the hidden secrets when we get there! ”

Everyone nodded. After these months of going out and adventuring, we all believe that we have what it takes to travel to that place and find the secrets within.

The fat man asked, "Then when are we leaving?" ”

Lu Feng said: "There is no time to delay, it is best to set off tomorrow!" ”

"Wait, aren't we going to help Lin Yifei pick up his younger siblings first?" I reminded.

"If the source suddenly changes its position, or something happens, the secret will be buried there forever." Lu Feng said.

I raised my voice slightly: "No, it won't take much time to get the guy back, let's pick up his siblings first, and then go find the source!" ”

"I'm against it!" Lu Feng said, "Now I don't know how many enemies are eyeing us around, finding the signal source as soon as possible is the highest priority, and then I have no opinion on how you want to save people." ”

His words infuriated me, and I said excitedly, "How long are you going to worry about the sky?" It's not enough for us to kill his parents, but also for his younger siblings to die? Lu Feng, do you have a clear conscience? Do you refuse to tilt the scales of your heart even a little for life? ”

In the end, it almost turned into a roar, I gasped, and Xiao Lin stroked my back.

Lu Feng was silent, just looking at me. From his eyes, I read a clear conscience, and even a hint of compassionβ€”an expression of pity for my ignorance. So, I couldn't hold back my emotions anymore and grabbed him by the collar: "Aren't you really going to help a child whose parents you killed them?" ”

"Not intended. And his parents were killed by zombies, not me. He said justifiably.

"What?" I felt like an angry balloon, there was a wave of anger looking for an outlet, but I could neither convince Lu Feng, nor change his mind, so the balloon could only grow bigger and bigger, and finally burst......
