DIY radar detector repair

In detail: do-it-yourself repair of the radar detector from a real master for the site my.housecope.com.

ANTI-RADAR SCHEME

Probably every driver at least once had the idea to acquire a radar detector, especially after another racket of a traffic policeman on the road. So get down to business! But let's clarify right away: a radar detector is a device that suppresses police radar, and its assembly is a very difficult task. Here we will consider a simpler anti-radar scheme - the so-called radar - a detector that signals that an inspector is scanning your car.

To measure the speed of a car, the traffic police radar receives radiation reflected from the car, and the radar detector - direct, therefore the radar detector is always able to detect the radar earlier than it measures the speed of the car! So, if a traffic cop scans from his radar 500 m from the car, this is the range of the Vizir device, then before the car approaches a visible distance of 100 m you have the opportunity to slow down.

This anti-radar scheme is quite common on the network, and although I personally did not assemble it, I had to repair such a homemade device. There, a microwave diode - the detector stood in a small funnel made of tin and the whole structure fit into a body soldered from foil PCB, the size of a pack of cigarettes. Under microwave irradiation, it blinked and peaked. Here is another version of the anti-radar circuit from the Radio magazine:

All radars in service with the traffic police operate at frequencies of 10525 MHz, 24150 MHz and 34700 MHz. These radar detectors are capable of detecting all of them.

Setting up the anti-radar circuit can be done while standing close to the person with the radar;

Or so as not to light up, near the stationary radar - camera:

Sometimes they are placed a couple of kilometers in front of the traffic police post:

Recently, the authorities have adopted: The VIZIR radar video recording speed meter consists of two independent units - a speed meter and a digital photo and video camera. The camera turns on both automatically when the driving car exceeds the preset speed limit, and manually - by an auto inspector. Surveillance cameras with built-in radar. The device works constantly, and when the speed is exceeded, the sensor is activated, which activates the camera.

The market also offers radar detectors. This device is not prohibited: nowhere in the law is it written that you cannot use radar detectors. Here are some examples of branded foreign products:

Cobra XRS-9445 Radar Detector. Price: $ 109.99

Cobra XRS-R9G with GPS Speed & Red Light Camera Detector. Price: $ 229.98

Cobra XRS-9970G Radar Detector. Our Price: $ 319.99

Questions about radar circuitry? FORUM

gusek, they are on several bands (modern). For the microwave range, a microwave generator is needed IMHO in the region of 10-12 GHz (or pile from a waveguide and a Gunn diode - drill a waveguide in a certain place), + optical range - for a laser rangefinder, there must be a lens in the antiradar.
If the sensitivity is regulated, turn until a beep appears.
If not, look for the generator of the G4-XXX series and look for the detector with an oscillator, that is, move from the indication to the beginning.

Or a familiar traffic cop with a radar.

gusek, Place 4 stoves next to it and press the “+” button on the keyboard.

In fact, I have 2 pieces lying around, so I'm waiting for a convenient moment when a thread of friends I know breaks, so that a couple of radars on different diapanos can be removed from them.

Currently, devices such as radar detectors are gaining more and more popularity among our compatriots. Such devices are designed to fix cameras, as well as police radars, which are used to determine the speed of a car and warn the driver about their presence. Like any other gadget, the detector can fail over time. In what cases it is necessary to repair radar detectors and what malfunctions are typical for such devices - we will talk about this below.

How to check such a device at home?

If we are talking about diagnostics of functionality, then the gadget is checked in the car, the diagnostic procedure is as follows:

What malfunctions are most often manifested in the operation of detectors:

As for the repair, it is far from always possible to carry out it with your own hands. If you have the appropriate knowledge and skills, you can try to repair the detector yourself.

How can you restore the device to work:

Is your TV, radio, mobile phone or kettle broken? And you want to create a new topic about this in this forum?

First of all, think about this: imagine that your father / son / brother has an appendicitis pain and you know from the symptoms that it is just appendicitis, but there is no experience of cutting it out, as well as the tool. And you turn on your computer, access the Internet on a medical site with the question: "Help to cut out appendicitis." Do you understand the absurdity of the whole situation? Even if they answer you, it is worth considering factors such as the patient's diabetes, allergies to anesthesia and other medical nuances. I think no one does this in real life and will risk trusting the life of their loved ones with advice from the Internet.

The same is in the repair of radio equipment, although of course these are all the material benefits of modern civilization and in case of unsuccessful repairs, you can always buy a new LCD TV, cell phone, iPAD or computer. And for the repair of such equipment, at least it is necessary to have the appropriate measuring (oscilloscope, multimeter, generator, etc.) and soldering equipment (hairdryer, SMD-hot tweezers, etc.), a schematic diagram, not to mention the necessary knowledge and repair experience.

Let's consider a situation if you are a beginner / advanced radio amateur soldering all sorts of electronic gizmos and having some of the necessary tools. You create an appropriate thread on the repair forum with a short description of “patient symptoms”, ie. for example “Samsung LE40R81B TV does not turn on”. So what? Yes, there can be a lot of reasons for not switching on - from malfunctions in the power system, problems with the processor or flashing firmware in the EEPROM memory.
More advanced users can find the blackened element on the board and attach a photo to the post. However, keep in mind that you are replacing this radio element with the same one - it is not yet a fact that your equipment will work. As a rule, something caused the combustion of this element and it could “pull” a couple of other elements along with it, not to mention the fact that it is quite difficult for a non-professional to find a burned-out m / s. Plus, in modern equipment, SMD radio elements are almost universally used, soldering which with an ESPN-40 soldering iron or a Chinese 60-Watt soldering iron you risk overheating the board, peeling tracks, etc. The subsequent restoration of which will be very, very problematic.

The purpose of this post is not any PR of repair shops, but I want to convey to you that sometimes self-repair can be more expensive than taking it to a professional workshop. Although, of course, this is your money and what is better or more risky is up to you.

Well, what about the irradiation you turned it down. Despite the fact that everywhere there are mobile networks, wi-fi and the like, your radar detector will not do anything wrong. It just might be a problem due to its illegal use. Install a radar detector)

and which model is more reasonable to choose?

I hear about it for the first time.

difference in terminology
a radar detector is essentially a special device that disables the radar. it's illegal everywhere.

thanks, now I will know. I'll think about it.

Cyril, where does infa come from?
for example, to normally mute the phone, you think the phone has enough power. you need many times more! And this is not taking into account that it is necessary to jam the entire potential band and not a couple of frequencies at which the signal is actually transmitted (!)

And where does the infa come from that the radar detector is harmful to health? If the rays are directed, then all the more there is nothing to be afraid of. Maybe you don't use a microwave either? There, too, the radiation is good

It's just that there is powerful radiation in the antiradar, that's all. If a person is irradiated like that, then nothing good will happen. But this is all theory

something in the news slipped the idea of the traffic police to ban these things.
who thinks about this?

Yes, this idea is not the first time jumping, but has not yet been banned. If they are banned, they will come up with something new.

And what can you think of new here?

And what can you think of new here?

But you never know what. Once upon a time, there were no anti-radars, and there were no detectors. Then they came up with it. Well, that's the same and something else will come up with. Progress.

Does anyone in Saransk repair radar detectors?

Radar detector stinger 430. Signal level indication scale from 1 to 9. When the radar was detected, it showed indication from 1 or from 2. Now only from 3. I started to catch worse, from a shorter distance. Check it out. Or tweak if you can.

Definitely leaving the local oscillator setting in the horn. In general, it is the three brands mentioned above that suffer from this. Bring it, I'll return it to him, but as I wrote, some parameters cannot be restored without a debugging stand, and it is not in Saransk. And if there was, the cost would not be appropriate for repair.

Question after inspection. Maybe I won't be able to restore it.

Heterodyne IMHO has nothing to do with it. The horn is mechanically damaged (fell off, fell apart, etc.), or the vibrator moved away from its place, either in the horn, or do not disappear on the board. Disassemble it yourself and see.

There will be a reception, but the sensitivity will decrease. The receiver in the radar, I think, is quite broadband, and when, when detuning the local oscillator, only the peak of the highest sensitivity shifts along the spectrum, I think it will still be captured by the receiver.

With such malfunctions, there will be no reception at all. For the listed brands, it is the local oscillator settings that float away. Repeatedly tested. Without a source with stable radiation both in frequency and impulse, it is impossible to understand in which direction the adjusting screw to turn.
I usually tune with my Spark.

With that shit that stands in crunches, the local oscillator settings just go away from time to time. Have you ever seen what's inside them (I mean crunch / star / stinger)?

I chose blue from 2 offered color options. The device is quite small, it is connected via a cigarette lighter.The fact that it is on is signaled by a dot on the block. The settings are intuitive, I immediately chose the "city" mode. Tellingly, at first it was even unusual for me - the silence in the cabin! Only in the most unexpected places for me did the radar begin to sound - I did not even suspect that there were cameras there, recording speed violations. It was this radar that saved me from new fines. He even fixes the devices that are in special vehicles - he was also convinced of this. The purchase turned out to be extremely useful for me - I have not received a single fine from the date of installation of the anti-radar.

To replace the fuse, you must:

one.Unscrew the top of the cigarette lighter adapter by

power cable. Remember: you need to unscrew it slowly, since
the fuse is held in place by a spring that can “fly out” when
removing the adapter cover.
2. Remove the fuse, check if it is defective and install
new (spare fuse included).

4. OPERATION OF THE LASER / RADAR DETECTOR

Power on and self-test

To turn on the instrument, make sure that the power socket is

the detector is connected by a power wire to the cigarette lighter, turn on
the device by turning the volume control away from you until
hear a slight click.

After turning on the detector, as a self-test

all the LEDs that correspond to each of the
ranges and operating modes determined by the device, as well as
sound signals of X, K and Ka bands are reproduced. Then all
LEDs go out, except for the power indicator [

Light-emitting diode).
Memory of the set settings

After turning on the device, it automatically remembers

the adjustments you made even if the power was turned off
from the device. The device memorizes the brightness level (Dim), any of the three
modes CITY and SILENCE mode.
Volume control

Adjusting the volume of laser / radar beeps

directions away from you and towards you (see Fig. 1).
Changing the brightness of the display

The Dim function decreases the brightness of the display. Click the button

"Dim" to reduce the brightness of the LED display
by about 50%. By pressing the Dim button a second time, all LEDs
except for the green LED [

] (Power) will go out. To exit the mode

and restore the display to full brightness, press the Dim button again
once.

In modern cities, and in industrial zones, your

the detector may encounter many weak radio signals, not
related to strong signals from the police radar. Source
radio interference

repeaters, high voltage lines, satellite equipment and
etc. To prevent the detector from responding to unnecessary signals, it
provided for the CITY mode, the mode for changing the sensitivity
receiving device Laser / Radar detector, which significantly
reduces the number of false positives. It is also important to know that
old and cheap radar detectors can also be sources
weak radio signals to which your detector may respond,
so remember to turn on CITY mode where necessary.

Unlike most radar detectors,

sensitivity level: ROUTE, HIGHWAY and CITY mode.

• To enable TRAFFIC mode, press the City button

once, the green LED [

(Highway) provides maximum sensitivity and range
reception of radio signals. This mode is ideal for out-of-town
driving where there are almost no false signals, and high speeds
require early warning of signal detection
police radar.

• To turn on the HIGHWAY mode, press the "City" button

the second time, the green LED [

intended for driving on city highways.

• To activate CITY mode, press the City button in the

the third time, the green LED [

designed for driving on city streets.
SILENT mode

Pressing the MUTE button decreases the volume

continue to function. By pressing the "MUTE" button a second time, you
turn off all audible alarms completely. To exit the mode
SILENCE Press the "MUTE" button a third time.
Radar Signal Detection
When radar is detected, Laser / Radar detector

You as follows:
1. For each of the X-, K-, and broadband Ka-bands, the detector
produces sound signals that are different from each other in tonality. How

the closer you get to the radio source, the more often you
signals will be issued. When the received signal level becomes
especially strong, (close proximity to the source), sound
the signal becomes continuous.
2.In unison with the audio signals (with the same frequency), the
corresponding LEDs (orange for X or red for K and
Ka-bands).
When a laser signal is detected:
1. The device will emit a distinctive sound signal.
2. Orange LED under the letter [

] will light up and start flashing.

3. Laser signals are the priority for your detector.
If both laser and radio signals are present, the detector

detects and warns you first about laser signals, and
only then about radar signals.

laser signals of three types: LTI20-20, Ultra Lyte and ProLaser.
VG-2 system signal detection.

VG-2 guns are called “radar detector detectors”. This

emitted from automotive laser / radar detectors. Such VG-2
guns are in service with the police in countries where officially
the use of radar detectors in cars is prohibited. At
VG-2 signals are detected, the display will simultaneously light up three
LEDs X, K and Ka bands.

Note: throughout the Russian Federation

the use of radar detectors is not prohibited.

Pulse radar detection.

Pulse police radar is much more difficult to detect,

than conventional speed meters, since it remains inactive
condition,

pulse radars. When detecting signals from such a radar,
the detector will emit a very short beep and the LED will start
flash at a very high frequency.

5. POSSIBLE FAULTS

If the laser / radar detector does not turn on:

1. Check the power cable. Make sure both plugs are
inserted into the corresponding connectors until they stop.
2. Check the fuse for the cigarette lighter socket of your
car. Refer to the vehicle manual.
3. The cigarette lighter socket may be clogged. Blow the nest
cigarette lighter with compressed air and wipe with a cloth dampened
alcohol. To achieve maximum contact, clean the socket
fine sandpaper.
4. There may be a problem with the wiring of your car
(faulty electrical circuit).
5. Make sure the detector volume switch / control is
is in the "ON" position

metal objects into the cigarette lighter socket. This can lead to
to a fire in your vehicle's wiring.

Check the electrical circuit of the vehicle, including the terminals

storage battery and generator.

Check the reliability of the on-board network connection to the socket

Insecure signal reception:

Check the angle of the detector.
Aim the detector with the antenna towards the horizon.

The radio antenna / laser sensor is obstructed

(wiper blades, other items).

Reinstall the detector to another level, so that it
