Scheme for soldering the megajet 150 tangent.

Tsya simple walkie-talkie to serve your sergeant for a long time should be respectfully put up to recommendations for installation, and for yourself: to trim the polarity and stability of the voltage of life, and also to increase the adjustment of the SWR and control of this value. Otherwise, the radio will stop "going into transmission" and will need repairs.

Three problem areas of the Megajet MJ-150 can be guessed about the coolness of the UHF transistor. We don’t call the vents far away, it’s rotten to cool down because of the small area of ​​heat distribution, the presence of the heat-conducting cavity and the non-sheltered connection with the radiator. Due to the presence of the antenna or the high value of the SWR, the external cascade is suddenly out of tune and the station stops transmitting. The potentiometers of accuracy and regulation of the level of the threshold of the control circuit of noise suppression are not affected by a high level of pressure and dbaylivogo cause. Otherwise, the model is far away.

Radio station Megajet 150 ma, in case of more important vipadkіv replacement of faulty elements, you can vikonate independently for the obviousness of working with a soldering iron. In this case, the replacement of the highness potentiometer or the noise suppressor, as well as the UHF transistor or the "protective" diode of the lancer, does not cause difficulties. Since self-repair is not possible, it became necessary to repair the radio in St. Petersburg or Moscow, please, contact our service center.

Fault parts Megajet MJ-150:

• UHF transistor burnout through weak cooling
• post_yni reshkodi - removal of the noise reduction handle
• no sound - speaker failure or ULF

3. APPOINTED MANAGEMENT BODIES

Warranty term "guarantee goiter" by the parties - div. "GUARANTEE GOITER" .

(3) RKI-Display. Information board for control of the state of operation of the robotic radio station. Great symbols and the type of indicator allow a great look around, which allows you to comfortably install the radio station both under the accessory panel and on the wall.

(4) AM/FM buzzer /SCAN. Select the type of amplitude modulation - AM or phase / frequency - FS. AM is victorious for close and medium range calls to ensure the most natural sound. In addition, AM victorious in the far-reaching channel 15С. Emergencies ensure the sounding and exchange of information at any distance, including great, if the signal that is received is sufficient and possible. Emergencies also vikoristovuєtsya in emergency channels 9C / 19C. And first of all, for all the modulation of your radio station, you are responsible for the modulation of your radio station.

SCAN - robot priymacha like automatic scanning. To implement the function, increase the liveliness of the radio station and install the necessary volume. Set up noise dampening. Press button "SCAN" for 3 seconds, that scan will turn up. A sign will appear on the PKI display "SC". When the channel is displayed, the signal at which the noise canceling level shifts, the scanning loops for 5 seconds. it is renewed again, right up to the pressure of the tangent or the button "SCAN".

(5) Channel 9/19 /BAND. Notice of emergency channels 9/19. To enter the emergency call, just press the button “9/19”. To select the BAND (A-E) option, press the button for 3 seconds by selecting the UP/DN buttons (8, 9).

(6) Button “-5kHz/ ASQ”. A short push shifts the frequency of the channel by 5 kHz down - so the titles of the amateur Russian standard for breaking frequencies between land channels. Trivale of pressure (about 3 sec.) - switching the type of noise reduction - from manually ceramic noise reduction (signal) to automatic (spectral).

At rocky sleepy activity, you can watch out for long-range radio waves (so-called pass-by) if you can receive signals and crossovers from radio stations that are thousands of kilometers away from your point of reception. For more comfortable work with correspondents of your radio, you can move between channels

-5KHz (there is a smaller shift here) either or go to manually adjusted noise reduction.

(7) ON/OFF/VOLUME -. Turn the handle after the year's arrow for the restoration of life and the installation of the required level of quality.

Respect. This regulator has a great mechanical resource (the number of new cycles of wrapping on natural wear before the waste of practicality). Alec resource, however, maє mezhu. Try to remember and do not turn the regulator especially often without need, especially near one and the same position and wine to serve a lot of years. Mechanical wear to the non-practical state of the regulator є mechanical failures, not transferring the warranty period to the guarantee goiter of the parties - div. "GUARANTEE GOITER"

On the rear wall of the radio station there is a socket for connecting the external speaker EXT. SP.

4. INSTALLATION OF RADIO STATIONS IN CARS

The radio station is recognized for use in cars with a 12-volt battery and grounding on the car body with a minus.

Before installing the radio station, turn the visibility of your car into a better one.

For fixing the radio station in a car, a mounting bracket and a microphone bracket are recognized.

WHERE TO INSTALL THE CIB RADIO?

The radio station is installed in a car in such a place, so that it doesn’t create inconsistencies and doesn’t cause water to be seen by a car. The best place for this place under the car's accessory panel.

Respect: Reconsider that when choosing a place to install a radio station, you won’t care about the water, and it won’t impair access to the car service authorities. Under the hour of laying the return cables, do it for safety. In the event of an unhandled opening of the radio station or cables, it is possible to open the connection by car.

MECHANICAL WORK AT INSTALLATION.

Step 1. To be careful, hurry up with the mounting bracket as a template for marking the fixing openings under the accessory panel. To understand the purpose of drilling, speed up with an awl, or with the other state tool, suitable for marking on metal.

Step 2. Drill two 3 mm holes for the skin screw on the mounting panel. Fasten the bracket under the side panel with self-tapping screws 10 mm (div. butt fig. 2). It is especially important to drill open, so as not to harm the happy jguti and electronic attachments, roztashovani under the panel.

Rice. 3. The butt of the fixed radio station with clamps-rams.

LIFE CONNECTIVITY.

Oskіlki radio station is equipped with a live filter for turning off the switch to the engine ignition system, it is possible to connect to the car's boarding facility at any point.

Step 1. Unplug the power cables from the battery terminals to avoid a short flicker, which can happen when a live radio is connected.

Stage 2. Please send a black minus wire from the radio station directly to the car body. For the shortest robotic radio station, an additional contact from the body metal is required.

Step 3. Get a black positive wire to the radio station from the start of the guard to the guard block (“cigarette lighter” or directly to the positive (positive) terminal of the battery). Sound the most convenient point for connecting the radio station to the alarm block. You can connect the live cable to the contacts of the ignition lock, in which case the radio station will be automatically switched on when the ignition is switched off, which will suit the battery discharge.

Stage 4. Connect the connection of live cables to the battery terminals. Connect the live cord plug to the live socket on the rear wall of the radio station.

Respect! Make sure the correct polarity is connected. The lack of polarity will bring the radio station to the point of poshkodzhennya. Such a failure to qualify as incorrect operation of the building, which was not transferred during the warranty period by the warranty goiter of the parties - div. "GUARANTEE GOITER" .

5. INSTALL THIS VEHICLE ANTENNA

In the Cі-Bi range of the largest width, antennas with vertical polarization were nabooly. Therefore, it is easy to place an efficient antenna with horizontal polarization in cars, and C-Bi calls are important for mobile objects. Antennas with a circular straightness diagram from the “grounded” base are installed from the mirror.

There are two types of antennas for mobile Сі-Бі radio stations - a fully-sized dash with a length of 1/4 length (2.75 m) and a shortened harness antenna (with a diameter of 0.5 to 1.9 m). Through the great dove of wide-width antennas on cars, there are mainly shortened antennas with a length of not less than 1.2 m, in other constructive vicons with fastenings through the opening at the dahu, on the brackets for the choice of the drain or on a magnetic base (div. fig. 6). ).

Rice. 6. Typical installation locations for car antennas.

Antennas on the magnetic base make that advantage, which is easy to get into the middle of the car at the parking lot, and the strength of the magnet ensures that it is stronger when shaking in Russia with a high swedishness.

In the place where the antenna is installed, lay down the straightness diagram. When the antenna is installed in the middle of the dash, the straightness diagram approaches a circular one. If the antenna is installed on the right edge of the dash, then the diagram and maximum strength will be directed to the left in front of the vehicle axle. When the antennas are placed on the rear trunk, the diagram will be straight forward.

Axis of these basic rules for choosing the place of installation of the antenna, as it is necessary to protect:

1. Install the antenna at the next point of the car.

2. The more part of the antenna is ruffled over the dash, the better.

3. Mount the antenna in the center of the surface selected for installation.

4. Lay the antenna cable as far as possible through the wires, such as fireballs, electromagnets, just fit.

5. Achieve a superficial screen under the cable, which is to be led, to the metal of the body (to the wire underlay surface) at the point of antenna expansion.

6. Since the antenna is equipped with a standard cable, it is not possible to change the cable.

7. Be careful not to damage the cable.

On fig. Figure 6 shows five typical installation locations for a car antenna: (1) rear bumper, (2) rear trunk lid, (3) water inlet, (4) hood, (5) exhaust.

For a qualified consultation on choosing the type of antenna and the place of installation, contact your sales company.

INSTALLED ANTENNI.

Carefully follow the instructions for installing the antenna, folded with a pick-up.

Respect! Do not, by any means, switch on the radio when the antenna is turned on, or with a loose antenna cable. The result may be that the radio stations are out of tune.

INSTALLATION OF VEHICLE ANTENNA.

The installed car antenna may be tuned to resonance at the middle frequency range. For the adjustment and periodic control of the antenna and the antenna cable, an SWR switch is installed, which is connected to the lance between the radio station and the antenna cable for the help of a cable-adapter with a minimum power. Different types of antennas can be adjusted in different ways, so you need to know the instructions. As a rule, the installation of the antenna, which may be over the HF stream above the galvanic (or else - through the entire area of ​​the magnet) contact with the wired underlaying wire surface (area) at the point of expansion of the antenna, it is necessary to change the shtir. Try to reach the minimum SWR (one is ideal) in the middle of the frequency band you have chosen (for example, between two channels, which are most often vicorous). And even if at the edges of the operating range, you need to take the SWR not more than 1.5, then your choice of channels is correct and the antenna is tuned perfectly.

WHAT IS IMPORTANT TO REMEMBER WHEN OPERATING A VEHICLE ANTENNA.

Respect, you can have some memories! In no case do not switch the radio station on transmission, wind it shortly, with a non-laid antenna or an antenna that is “broken”, if there is a superficial electrical contact of the braided cable and the “mass” of the antenna with a wired supporting surface at the point of expanding the antenna (antena) Saytuzії likeadbuisuysu in the Surgeons of the Perezozpodіl Silovik Lynіshniy Eckelomage Field І on the Zovnіshnіyi Surfі Rottennia Caburity Antenna Ta Sihtroprovniki Tone Tone, Ninepricksnish, the Allium Salon Vynikyut Visokascular Surfaces. You cease to be received close by the correspondents, and the tangent lightly burns the palm of your hand. Particularly significant is the level of high-frequency voltages on pro “concentrators” - space conductors, the electric range (the physical range is divided by a shortening factor) which is close to a multiple of a quarter of the length of the wind. Such obvious "hubs" are wire harnesses that hang freely, under the accessory panel, plug-in cords for charging attachments in style telephones and torsion cords for radio station tangents. Behind these conductors, high-frequency streams are not transferred to the elements of the electrical circuit of the car's accessories and the radio station itself in the middle and may cause irreversible damage. The most sensitive to such a splash is (behind the fall) the central microprocessor of the radio station (non-reversible power), the block of the cloakroom (short-hour sbіy at the robot), microcircuits for the memory of the car radio and, rarely, the telephones (non-reversible), the processor short-speed control system robots) ). Respectfully, however, what kind of damage is caused by the unacceptable operation of the radio station on the unfavorable antenna (“rozstroєnu” antenna), as evidenced by the statistics, blamed mainly on the fluctuations of the additional high tension. (For quietly absturbation of ABOUT ABOUT EXPLUDAYUєMYEєMO, Scho Nakіtniy Antenі, ale, with Mіnusovy Dronti, Alla, with Mіnusovy Drotі, Allah, Scho, Ohko, ABOUT, ABO with lack of bad wire, so self-free of the near electromagnetic field from the designations).

I have an unbearable factor at the time of the Civisnosti contact "Masi" Antenna Zpіdstilayucho, the surface of the cable, Scho not R_DKO to win to the zombie in the robot / Abo of the thorough sampling of the Mіkroprocessor of your Radiostantsії (Nakshchko Vimknen), є Riznitsya Static Potentyіaliv what a twist. car body and a long antenna line. In the Crimea, the range of communication in the dynamics of the radio station is affected by sharudinnya and trills at the hour of the car crash. The static voltage is blamed for the rahunok rubbing about the repeated potik and the covering of the road. At the same time, there is a difference in water content on the roads, wheels, body and antenna pin. As a result, between the antenna line and the body, there can be a significant difference in static potentials with further spark discharge in the antenna line - radio station - car body.

In this way, at the first sign of a decrease in the strength of the robotic antenna, it is necessary to reverse the integrity of all contacts and contacts, or turn to fahivtsya.

It is important that you periodically check the control of the SWR and the minimum regulatory check on the quality of the day, especially during the period of changing seasons, to ensure accurate water in case of unacceptable “non-warranty” situations and fluctuations.

6. RULES FOR RADIO STATION COMMUNICATION

· Check if the antenna is installed and connected to the cable to the radio station.

· Turn on the radio station to the handle wraps “Uvіmk./Vimk. that Register. Guchnosti” for the year's arrow. Install the volume.

· Adjust the squelch threshold with the Squelch knob.

· Select the required channel for the additional channel switcher (clause 3.11).

Note: As if perebudov canals are not closed, respect should be given, what can be done to the regimeCH9. In which case turn off the emergency call mode.

TRANSMISSION MODE.

Press the “Tangent” jumper on the microphone housing (headset) on the microphone. Trim the microphone body at a distance of 5 cm from the mouth and speak in a normal, understandable voice.

RECEPTION MODE.

Just let the tangent in and listen to your correspondent, brushing up on the volume controls and noise canceling to achieve the best sound quality.

7. FACTORS WHAT TO SPLIT IN THE RANGE OF CIB-BI ZV'YAZKA

Vision for civil radio communication, the frequency range of 27 MHz may have the power to expand the radio broadcast, which is the television range of the UKH. Сі-Бі radio wires expand similarly until the change of light along the straight line from the transmitting antenna to the receiving antenna. Falnish Lvkomykka Seek Vіd Bakhatochok Factor_v: Visita Installation Antenna Above Rivan Sishennya, Geodesic Tom Ta Rail Deutsu Resisti, Vipromyvanynya, Polarizatsakії Viprominovnya (Horizontal ABO vertical), Peremnkod to come, revealing trasі zv'yazku, mind vikoristovuvanoy modulation and weather minds.

Significantly lose your mind for Cі-Bі zv'yazku perebuvannya car at tunnels, under flyovers, in closed parking lots or at narrow courtyards of high buildings. In the minds of a place and a strongly twisted space, the signal to the receiving antenna arrives along several different paths and is added to warehouses with different phases, that level of the signal can change hundreds of times when the receiving antenna is shifted by more than 1-2 meters. This effect is especially important to secure the connection between the base and the car. Sometimes you need to send a little bit to move the car, so that the signal of the virus is on the sprat of the balls.

For good practical minds, the distance of the call with AM or SN modulation and intensity transmission of 4 W should be approximate: car - car - 10-15 km, car - base - 15-20 km, base - base - 30-60 km.

Dosit vpevneniy sv'yazok terrestrial hvileya in Cі-Bi range navit for friendly minds between the range of 75 km.

If you consider a significant change in the distance of the call, invert the reliability and reliability of the connection of the antenna and the C-B radio station. Possibly, you need a consultation about the choice of food from the fahivtsya.

Noise and pereskodi.

The sound of the noise and the shift at the point of reception is strongly influenced by the distance of the call. The strongest crossings are guarded near power lines, contact lines of electric trains, trams and trolleybuses. At the reception in the car, there can be a lot of noise and noise caused by the robotic systems and units of the car.

Сі-Бі priymach - highly sensitive attachment, building priymat and even weaker signals and noises, especially as a dzherelo tsikh signals are known on the vіdstanі dekіlkoh tens of centimeters. Whether it’s some noise, some kind of noise in the dynamics of the radio station, may be sing-songly, that the posture of the radio station is familiar, so that the radio station is broken up by strangulation and minimization of the equal noise.

Suffocating noise.

Nasampered perevіrte vіdsutnіst reshkod lanziugs zhivlennya. For this, equalize the noise of the receiver when the antenna is turned on until that time the engine is turned off. The same noise level means that there is no change in life in the Lanziugs.

The most intense source of ambient noise is the ignition system of the car, in which a C-B radio station is installed. If you take into account this possible reason, just turn off the engine and leave the key at the “Adjust the winding” position. In any case, life is on the radio station, but the system is not working. Even though the noise has changed significantly, the system of zaplyuvannya your car є zherelom shumіv.

For these changes, it is necessary to adjust the engine and replace old candles and dross. You can use high-voltage wires with silicone insulation and caps of candles with resistors, as well as an additional wire that puts the hood behind the body. Cі come in to change the noise level of the engine ignition system.

Advance: Do not try to repair or refurbish the ignition system for the day before the car is repaired. For which it is better to return to the technical service station.

The screen of a car alternator can be seen as a shift, which predicts the sound of a different height in the dynamics. Tsya vyklikana zarudnennym shield of the commutator and used to wipe the contact surfaces with a clean cloth or special accessories for stripping contacts.

The voltage regulator can eliminate the unacceptable noisy sound from the radio station dynamics due to the crackling of the relay contacts. To strangle the filter, install the filter as a coaxial cable with capacitors between the battery and the voltage regulator terminals.

It is also necessary to clean the contacts and the surface shield in order to change the inflow of the switch to the C-B connection.

In some cases, the jumper for C-B sound can be connected to electromechanical attachments of the car: fan motor, electric chimney, chute engine, they are blocked to strangle the jumper with coaxial capacitors (consult the mechanic from car maintenance).

Dzherelom reshkod for Сі-Бі sv'yazku pіd hour ruhu car dry highways can wind wheels and tires. The electrostatic noise of the wheels is taken into account by the installation of spring collectors to remove the static charge between the axles of the wheels and the crankcase of the engine. The static charge of the tires is changed by the accumulation of a special antistatic powder in the middle of the skin tire.

The noise of the corona discharge of the antenna is most often heard when the antennas are switched off from the bright end of the hour or before a thunderstorm. The only vihіd is to pass through the storm and cross.

The radio station came to finish with a cicava. The necessary set of functions allows you to win for the stake of the day. The station will feel good in channel 15 in AM, the threshold noise reduction will be deactivated, and in any other channel in FM, the automatic (ASQ) will be devastated. The management of the cycle is logical. Koristuvatsya station receiving. Klopit can deliver non-standard installation of certain elements. At my example, when pressing on the 9/19 button, the indication on the display disappeared. After soldering everything came back to normal. The station can be recommended for a wide range of zavdan, but after the obvious mistakes of the Chinese (prote, marvel at UPD2).

UPD: Due to misinterpretation, the building station is able to survive the connection to the 24 volt voltage socket without any special consequences. Repair after such a repair is called before the replacement of one electric battery for life. This sensi station is superior to its competitors (RV3DOH).

UPD2: Unfortunately, the statistics of the MJ-150 warships zmushue look at the previous appointments. At the present moment, the smartest would not call the radio station in principle, it’s not clear what the impending moment should be in it. Perhaps someone was spared and in the new station works without problems, but it doesn’t mean that everything will be good for everyone. Nextron, unfortunately, trims the mark.
