In detail: do-it-yourself repair of radar detectors from a real master for the site my.housecope.com.
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.
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
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 the situation if you are a beginner / advanced radio amateur who solders all sorts of electronic gizmos and has 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 replace this radio element with the same one - it is not 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.
If you nevertheless decide that you are able to repair the radio equipment on your own, then when creating a post, be sure to indicate the full name of the device, modification, year of manufacture, country of origin and other detailed information. If there is a diagram, then attach it to the post or give a link to the source. Write down how long the symptoms have been manifesting, whether there were surges in the supply voltage network, whether there was a repair before that, what was done, what was checked, voltage measurements, oscillograms, etc. From a photo of a motherboard, as a rule, there is little sense, from a photo of a motherboard taken on a mobile phone there is no sense at all. Telepaths live in other forums.
Before creating a post, be sure to use the search on the forum and on the Internet.Read the relevant topics in the subsections, perhaps your problem is typical and has already been discussed. Be sure to read the article Repair strategy
The format of your post should be as follows:
Topics with the title “Help fix the Sony TV” with the content “broken” and a couple of blurred photos of the unscrewed back cover, taken with the 7th iPhone, at night, with a resolution of 8000x6000 pixels are immediately deleted. The more information you post about the breakdown, the more chances you will get a competent answer. Understand that the forum is a system of gratuitous mutual assistance in solving problems and if you are dismissive of writing your post and do not follow the above tips, then the answers to it will be appropriate, if anyone wants to answer at all. Also keep in mind that no one should answer instantly or during, say, a day, no need to write after 2 hours “That no one can help”, etc. In this case, the topic will be deleted immediately.
You should make every effort to find a breakdown on your own before you get stumped and decide to go to the forum. If you outline the entire process of finding a breakdown in your topic, then the chance of getting help from a highly qualified specialist will be very great.
If you decide to take your broken equipment to the nearest workshop, but do not know where, then perhaps our online cartographic service will help you: workshops on the map (on the left, press all buttons except “Workshops”). You can leave and view user reviews for workshops.
For repairmen and workshops: you can add your services to the map. Find your object on the map from the satellite and click on it with the left mouse button. In the field “Object type:” do not forget to change to “Equipment repair”. Adding is absolutely free! All objects are checked and moderated. A discussion of the service is here.
How do radar detectors work? The following requirements are imposed on radar detectors:
The detection range of a signal by a radar detector is one of the most important characteristics of the device, since the amount of time to make a decision depends on it. In the "city" mode, the detection distance of the radar radiation fluctuates within 700-850 meters, outside the city the distance can reach 3 km.
Working range of waves - the wider the range of waves received by the device, the more models of DPS radars it can take direction finding. Today, without fail, radar detectors must operate at the following frequencies:
- X-band (10.525 GHz) is an obsolete frequency, models on it are not produced, but they are still found on the roads.
- K-band (24.15 GHz) - this frequency is used in most radars in service with the traffic police.
- Ultra X - short pulse range, introduced since 2002, used in modern Sokol radars.
- Ultra K - the K range of short pulse frequencies, introduced since 2004, is used in Iskra and Berkut radars, as well as in video recorders.
- VG-2 - radar detector blocker when detecting direction finding equipment from traffic police officers.
- POP TM is the frequency range of radars used in the USA.
Most modern models have a multiband matrix for determining the incoming signals.
One more antiradar characteristic - the ratio of false signals to real ones. It is known that the radar detector takes only part of the signals, in each specific situation there are conditions for false alarms (electric door locks with photocells, high-frequency emitters, terrain features, radar impulse).
Important characteristic radar detectora is the processing time of the incoming signal.Modern models of radars in service with the traffic police operate in a pulsed mode, with a short period of the emitted signal, operational reception and its processing increase the efficiency of the radar detector.
Reliability of the result - in addition to the coefficient of false signals, the reliability of the data, the correspondence of the received data on the distance to the radar, plays an important role.
Appliance functionality - Premium models are equipped with additional features to make the appliance easier to use. For example, a local oscillator built into the antiradar circuit has a blocking system in the presence of a DPS radar. Local oscillator sensor without phonit protection with amplification of the signal from the radar.
Reliability - the radar detector is used in a dynamic mode, since it is quite rigidly fixed on the front window of the car (the rubber suction cup weakly dampens shock loads), therefore, all potholes and irregularities in the road turn into vibration. Continuous exposure to vibration when the instrument is poorly executed can result in poor readings.
In addition to the listed characteristics, radar detectors can take direction finding of laser signals, however, the determination of laser exposure does not have accurate statistical data due to the specifics of the application of such radars.
Radar detectors are manufactured in a monolithic case, so most breakdowns can only be repaired at a service center. Among the frequent breakdowns - the radar detector constantly beeps, the radar detector does not work, the radar detector does not catch. Some of these faults may not be such. If your anti-radar does not catch any one type of radar, it may turn out that it is simply not capable of this constructively. There is also an uninterrupted supply of signals in the city, but, as a rule, this is not a defect, since the device must be switched to the “city” mode. Any repair of radar detectors is best done in a service center or at authorized dealers, if the warranty is valid. Self-repair can finally "finish off" your radar detector.

Whistler 138 Ru is a radar detector, not a radar detector
What's the difference? I’m, you might say, a teapot. Explain, if not difficult. Or where to read something sensible about it?
difference in terminology
a radar detector is essentially a special device that disables the radar. it's illegal everywhere.
the detector only informs about the possibility of irradiating it with signals similar to radar. it is illegal in some countries. in the RF norms.
Actually, modern radars are less visible and the meaning of a radar detector is becoming less and less.

tripods emit constantly and they are "visible" from afar.
The vizier works on the sight. but most likely, if you are not alone on the road, they will check the cars in front and again you will cross ..
Stationary arrows are few and far between, and they are close when it's too late.
well, hair dryers without video recording seem to have been banned
about antiradar - it is a source of strong electromagnetic radiation .. is it pleasant to be irradiated yourself? well, for the time being it.
a couple of times you will drive .. then the facts will be compared. This time .. well, and secondly, it is not a fact that this radar detector will effectively drown out the entire frequency band, so it can be useless, especially since different radars work in different ranges - and all to jam, it is necessary to carry a cart with an additional generator

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)

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
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.

Don't drink while driving! 11 oct. 2012
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.
As for me, all these anti-radars and radar detectors are illegal, or at least go against their conscience. It would be better for something to come up with a device so that drivers observe traffic rules
Why is it against your conscience? What's so terrible about that?
I am engaged in periodic repairs of various gizmos, be it a mobile phone, car radio, tape recorder, or something else. But on the weekend a friend came to me with an unusual request (this is the first time). In general, he brings a miracle of Chinese technology: a car DVR + radar detector in one bottle. There are no complaints about the DVR, on the contrary, the quality of the recording is such that the license plates of any car are visible when viewing the recording ... But with the radar detector, it was less fortunate - there is only an ON / OFF switch from the radar control bodies, and nothing else. Even the volume of the beep is not adjustable. Yes, to hell with her with the loudness, the problem was different - when the anti-radar was triggered, the loud voice of a woman whose accent is similar to Allah-akbar is heard from the device, and even all the words are "mixed up", as if the text was translated through "promt". And the voice is so disgusting that when I heard it for the first time, my brain almost blew up ... The client asked: do at least something to at least squeak, but so that there is no trace of this voice (but accordingly, so that the radar detector works).
Well, let's get started. At first I wanted to do something like this: take a small microcontroller, for example ATtiny13, send the signal from the speaker to the MK comparator, and then generate a squeak using PWM. Approximate scheme:
But then an unfortunate situation happened: I forgot the microcontroller programmer at work, and it was New Year's holidays outside. Therefore, the option with a microcontroller had to be abandoned. I started to come up with another scheme. I rummaged in my storehouse, and found a small handkerchief from a Chinese mechanical alarm clock. This shawl can serve as a buzzer generator, with a power supply of only 1.5 volts. In order for the squeak to start, it is necessary to close two contacts signed on the photo "ON", "ON". In the photo, the contacts are already closed with a drop of solder.
This means that I have decided on the generator. It remains to come up with a circuit that will react to the audio signal supplied to the speaker and turn on the "buzzer" for three seconds. To do this, I decided to first measure the level of voltage present on the speaker when the woman "pushes speech." The output sound amplifier turned out to be built on a bridge circuit, and relative to the common wire, at the moment when the woman pushes the speech, a voltage of about 1.3 ... 1.4 volts was present at each of the amplifier terminals (half the amplifier supply voltage). After the woman stopped chatting, the power of the amplifier was turned off, and everything went to zero at the output. I took advantage of this, connected the generator scarf directly to one of the speaker terminals. The negative wire of the generator-buzzer was naturally connected to the common wire of the anti-radar. Since the generator-tweeter consumes current in short pulses, I hung an electrolytic capacitor with a capacity of 1000 microfarads on the power terminals, so as not to overload the output stage of the amplifier.
Naturally, I tore off my native speaker in order to deprive the "Allah-Akbar" woman of the opportunity to talk. And in the old place (where the speaker stood) I put the generator-tweeter handkerchief, and glued this handkerchief to the thermo-nozzle. The quartz and condenser are also fixed on a thermo-nozzle to protect against vibration.
By the way, there was only one free space in the case near the speaker. This is what happened in the end (under the train you can see the brown getinax shawl of the generator-tweeter):
Finally, I throw a few photos of this miracle of technology from different angles. This device does not even have a model written on the case. Well, I also attach a video about the finalization of the device.
The client left me satisfied and happy, with a device that fully satisfies his needs. All successful improvements =)
P.S. Who does not understand, the device works at the expense of one shoulder of the bridge ULF, tk. in the absence of sound, the ULF is turned off and the output stages are de-energized.

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.

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.

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.

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.

We will be sincerely glad to be useful to you - dear farmers.
Good build quality
recognizes radar signals in the stated ranges
Whether he sees everything is unknown, but he sees something in each of these ranges, because it shows their signs on the display during operation and names them.
Normal sensitivity
In the mode, the city does not react to everything. For example, does not see: cameras, shopping center doors, traffic lights, etc. If you need them, you must enable the track mode.
Detection of the Strelka-type radar signal - when it is stationary, approximately 300 m away (without a GPS connection). With a connected GPS - for 500 m or more, but this depends on the availability of satellites and a map.
Beautiful appearance
The device has a bright display and loud enough sound, of course it is aimed at hearing impaired people.
Nice female voice with good diction
There is a button - "on / off".

Before proceeding with the setup of the Cobra TM radar detector, it is necessary to correctly install this device, ensuring its correct operation. The detector should be installed parallel to the road. You may need to bend the bracket slightly once to position the instrument horizontally. It is better to install the device in the middle of the windshield of the car as high as possible so that in places with a difference in elevation the detector is triggered as soon as possible. Keep in mind that toning can degrade the sensitivity of the device by 10-20 percent. Thus, if you have a tint strip glued to the top of your windshield, it is better to install the device lower. Also keep in mind that athermal glass with a purple tint degrades the sensitivity of any antiradar by 40-60 percent.
Most often, such glasses have a technological window that does not have any athermality - it is in this place that the gadget needs to be installed. You will find information about this window in the documentation for your machine. as a rule, it is located somewhere under the rear-view mirror.
You can check the windshield for athermality by experience. Just stand in front of an active signal source, for example, in front of a traffic police radar or a sensor for automatic doors that work in the K-band, and check the signal strength of the device from the car and from the street. If you notice a difference in the signal strength, your glass is athermal and the low sensitivity of the antiradar is connected with this.
It is customary to configure the radar detector once, after which the selected parameters are saved in memory. Today, in our country, they use mainly two ranges in which police radars function:
- X - in this range, the Falcon-type radar works, which has long been discontinued, but in some regions they are still found.
- K-band - modern speed meters work in it.
- Separately, one can single out laser radars, which do not work in any specific range, but function due to the wavelength of light, which is measured in nanometers.
There are other frequency ranges:
These ranges are not yet used in our country, so we advise you to turn them off. First of all, this will reduce the frequency of false alarms. Regardless of the fact that there is no measuring equipment in such ranges in our country, triggers from other sources are not excluded. The speed of the gadget's processor also increases, since it will work to recognize only certain ranges.
It should be noted that in the new Cobra antiradars, the Ka band is enabled by default and cannot be disabled. The X range is enabled in the settings and you can turn it off if necessary. Frequency bands unused in our country are disabled by default. In other words, modern models of Cobra radar detectors are configured for operation in Russia. In the factory settings, the Trail driving mode is selected - it is optimal in many cases.
In the urban mode of operation in the models of the Cobra RU 935, 945, 955 and 745, 755 and 775 CT radar detectors, the signal strength with a power of one and two is not sounded, so we do not recommend using the mode in an unfamiliar area. City and City Max are well suited for cities where cops are mostly armed with Riflemen.
For the convenience of using the detector and getting the maximum result from it, you will need to get used to the gadget for a certain time and learn how to correctly recognize the information. For example, the appearance of a short and weak signal in the K-band almost certainly indicates a false alarm. However, a stable signal almost certainly indicates that a radar has been detected.
Do not forget that in addition to police radars, other equipment operates in the above ranges, which have a weaker radiation that the detector can work on. These can be sensors for opening sliding doors at gas stations or in stores, power lines, cruise control in cars, cell towers, satellite dishes, etc.
To reduce the frequency of unnecessary alarms, we advise you to do the following:
- Disable ranges that are not used in our country.
- Switch between City and Highway modes. In the first case, the received signals become coarser and the number of false alarms decreases. In this case, the sensitivity of the sensor decreases.
For increased comfort, you can use the IntelliMute option, which is not available on all radar detectors. Setting the function makes it possible to drown out the functioning of the gadget at low speeds. These are the cases when the use of the detector is not relevant. Suppose you are in a traffic jam or approach a mall where there are door sensors and you simply cannot exceed the speed limit in a parking lot.
Please note that the range of the anti-radar response largely depends on factors such as:
- geography of the area (winding or hilly road, lack of reflective objects and surfaces);
- the type of police radar used (high, medium, low power);
method of installing the radar (in the back, at an angle, in the face); - weather, traffic on the road.
It is impossible to determine in advance the maximum range of the anti-radar, since in each specific case the combination of factors affecting the range may be different.
Also, you should not use two antiradars at the same time, since the heterodyne background of one device can interfere with the operation of the other.

Keep the radar detector away from a functioning police radar at close range - up to five meters. It is not normal to use it, and the detector board might just get damaged.
