I pull out the chassis from the plastic body going with a screwdriver or something like that. Chaspsia goes hard, because between it and plastic there is a rubber moisture insulating gasket laid around the perimeter.

We find the red wire next to the display.

Remove or snack it.

We all collect in the reverse order and turn on.

Now, instead of CH, the letters 0a appeared on the screen. This means that the station is in the grid A (C) and in zero. Switching between zeros and five is carried out by one button P by its long holding.
To switch between grids, you must perform the procedure similar to switching standards as usual. Turn off the station, clamp the F button and turn on the station.

Matching mesh letters is: a - C, C - B, B - D. Select the desired grid and confirm your choice button F.

In addition, the output power of the station increases to 8 watts. This mode is intended for use in the machine, as it will very quickly plant the battery. In addition, it is almost impossible to use the revealed station from hand, because the increased power begins to call all kinds of special effects and not a grounded radio station begins to burn hands with high frequency currents during transmission!

Each radio station has a characteristic - a working frequency range. This range is specified in the technical documentation and is responsible for the radio station's ability to transmit and receive a signal at a certain frequency.

However, a number of radio stations that the manufacturer specified by the manufacturer can be expanded.

How to reveal the radio in Moscow

Ways to open range differ for different models radio stations Most often, it is necessary to disappear, separation or movement of special jumpers on the station board. Such operations require special equipment and skills to work with electronics, so it is better not to try to produce them yourself if you never did it.
It is also necessary to understand that the manufacturer does not recommend making changes to the finished device and while restricting the range of operation of a particular model or a batch of radio stations, can be guided by various reasons.

In some cases, this is due to the rules for the use of radio frequencies of a particular region for which the party is intended. Sometimes the manufacturer saves on the production of parts and uses the same main components for different models, limiting them artificially by range.

In some cases, restrictions are established for more stable operation of the device so as not to increase the load on the transmitter or other components of the radio.

Why cost to entrust work RADIO-REPAIR?

Before deciding on the disclosure of the range of your station, it is better to consult a specialist. Is it possible to disclose for a particular model, it is worth it or not to do it? Can the disclosure have any negative consequences for the station's operation, will it be necessary to somehow change the mode of operation of the device after performing this procedure? Our specialist who has extensive experience in disclosing the range of various radio stations can be replied to all these questions.

For example, quite often, the owners of Yaesu, Icom, Kenwood, Alinco, Midland, Alan, and others appeal to us for disclosure of the range of their radio.

Contacts

Address: moskva, sh. Enthusiasts 17, 5th floor (m. Aviamotornaya).
Service center operation:
from 9:00 to 18:00 Monday - Friday.
On holiday and weekends service center does not work.
The building has a passage system. With you, you must have a passport or driver's license.

This article is primarily useful in groups that have some kind of developments on the usual voices of voice communications with each other.

I have long been looking for the opportunity to organize through the usual analog VHF radio station sharing and the image.
Earlier, it all required the presence of a PC connected to a radio station with a cord, special software and iron (modem), as well as skills, i.e. Provide all the "radio amples" of their camrads not related to the category did not work with such devices.
Not so long ago I got a recommendation for Bourgeisky software under androidAllowing to carry out all these, so desired by me actions, just downloading a couple of inexpensive programs to your tablet or a smartphone. In the stationary (home use) for work it is not necessary to have any cords, the built-in microphone and speaker are used.

Donoshu the most essence - Amateur VHF frequencies are used by all and not always well exchange with your comrades messages that are heard very many. Of course, it is possible to buy expensive radio encryption (which in principle we are prohibited), you can use codes and special negotiation tables, but it requires relevant and identical codes from all and serious time loss of such communication. A bad audibility can create a big trouble in transmitting codes, and it is worth 1 letter or a digit in such a "radiogram" to be accepted incorrectly and you do not decrypt anything, you have to strictly observe the Radiocommunication Culture and be sure to dictate it to each other for rechecking. In the total time to transfer a unit of information to take a lot and not necessarily with a positive result.

The same program found does not require qualifications to use it, it is enough to enable it (text or image) and simply put next to the radio station.
When it goes off and sinking, it will delete information from it and accepted letters will run on the screen.
You can write a message for transmission as onlan i.e. Squeezing letters in the transmission process, but you can score the text into the memory cell (it is very simple) and in the coordination of the readiness of the reception on the other hand literally shoot a telegram. I tried, with this method of exchanging time on the broadcast, it turns out less than 2 times than if you dictate the same text by voice slowly and picking up.
Your radio station must or enjoy the VOX function or you will have to go from the device at the time of the start of transfer from the device, click on it manually and release the tangent.

For field conditions, it would be nice of course to connect the radio through the cord to not demack yourself when transmitting and receiving loud sounds. The sound and essential interference is not quite criticalI have been doing this "nonsense" at the testing of the server, next to the buzzing rack with equipment. I recorded the sound from the tablet to the voice recorder in the phone and immediately played it in the noisy room, there were practically no errors, the occasionally distorted or some characters were passed and the general meaning was not lost.
That the most remarkable gear successfully goes through the repeater, which is relevant for us. Another convenience of textual transmission of important information, there is no need to asked, the text can always be reread and the transmission can be carried out with a circular i.e. From one to all and immediately.
small inconvenience - It is necessary to write in Latin's translite, writes by Cyril, but it does not pass on the ether. But I think some remember those times when every SMS cost money! And to give more characters, many wrote SMS Latinians to fit "poem" into one message))).
This is how the experiment looks like with the transfer of the image and the text through the radio.
i didn't spend it no longer.

Sum up - You will not get a serious closure of information calaped by the relevant authorities, but from 90 -99% of curious ears your radio wake will close. You can quickly convey something important to all your. At the same time, people do not necessarily sit at home in places of the best reception with a walkie-talkie and listening to continuously, it is enough to put a smartphone next to the radio station with a launched software (or connect through the cord) and engage in more necessary affairs. If necessary, you can send a map or photo in a low resolution.
Use this method transmissions can not only at VHF but alsowhere the range and the number of listeners will increase, respectively, a decrease in the audience of those who understand will be even more useful.

Well, at the most important link to the site of the miracle program, you need applications DROIDPSK. (text) and Droidsstv (Pictures). It is worth a penny, but there are ways to find on the net and free - will send for example the forum from where pictures are taken.

What communication do we use, doing active sports and recreation?

Cellular telephone, not always convenient, does not always work.

Satellite, yes, in some cases, this is the only connection with the "Large Outlies".

Now about everyday realities.

Someone bought the "Soapnya" radio, who snapped something more thanks, in some ammunition, many range stations.

When all the stations are the same, we usually have no problems, everyone hears each other. And when the stations are different, how to "make friends". After all, not all people engaged in one family activities are identical radio stations.

Situations requiring to construct different stations can be a lot:

- Ski, you want to make a guide to the guide.

- Going on several cars on vacation, a large company.

- communicate in the mountains with other groups of climbers.

- got into trouble, ask for help.

- interact with other groups with savingings.

Let's first consider what radio stations are.

From simple to complex 😉

"Soaps"

"Soapnya" - "Silence Return" ®

page so they are made by transmitter power and frequency.

You probably noticed that there are different number of channels on the radio: 69 channels, 22 channels, 8 channels. P with a different number of "subchannels", remember, the subchannels do not exist, in most you call this terrible word Tone CTCSS or digital DCS noise cancel. What it is, look in the application, at the end of the material.

The same labeling, on boxes, radio, or under batteries: LPD, PMR, FRS / GMRS.

Let's deal with what and what.

FRS / GMRS is an American standard for household transmitting devices, work at frequencies that are not allowed in Russia to use, a simple one-in-law. Use these races on legal grounds will not work.

PMR ("Personal Mobile Radio"), 8 channels for racies with a transmitter output no more than 0.5 watts are isolated. The European standard of household transmitting devices (446.00625- 446.09375 MHz) due to a 6.25 kHz mesh step, they are not compracted by almost nothing more than the same PMR racies. On amateur stations, where there is no step 6.25 kHz, you can make a slightly spoke from the specified frequency. Registration of radio stations is not required.

LPD (Low Power Device) can be used freely - the registration of radio stations is not required. They operate in the range of 433.075-434.775 MHz. The most successful household radio stations for active spending time, especially if you bought the "correct" models that can be rebuilt on a slightly large power (up to 3 x W) compared with the allowed 0.01W. There are models with a screwing antenna, you can replace it with a longer antenna from a professional or radio station station, which will greatly increase its receiving - transmitting characteristics.

Table matching frequency channel numbers and noise reducer tones Look in the application.

P.S. LPD (SRD) radio stations are not allowed in the following countries: Belgium, Denmark, Finland, Praland, Luxembourg, Portugal, United Kingdom, Pspane, Lithuania, Latvia, Estonia, Croatia, Turkey.

There are no such restrictions for PMR racies, you can safely go abroad and use them freely.

Regarding FRS / GMRS so this range is prohibited primarily in Russia. 😉

Radio amateur stations.

How not all apples are equally useful®

So not all Kenwood is Kenwood.

(Amateur wisdom)

Good connection is not cheap. From these words I want to start a story about the mid-level equipment.

Chinese Kenwood TK-K2AT, TH-K2AT and TK-150S Range 137-174 MHz, or TK-K4AT, TH-K4AT and TK-450S Range 420-470 MHz work with any LPD / FRS / GMRS "Soapnya" price less than 100 $ thing. These and other, such devices, in our country are sold quite wide.

BUT! Oh, if you knew how I myself do not like such "but". The radio of this price range, with the stated characteristics - the cat in the bag.

Reliability \u003d reliability, durability, maintainability.

That's just reliability in these dwarves and lame.

How fast she stops working either not known. This equipment, class, will be lucky - not lucky, proven on your own experience.

Kenwood. good manufacturer, professional equipment, for adequate money. If your kitakenv worked, remember Kenwood here not to happen, he did not see these stations in the eyes.

There are so-called "two bend" radio stations that combine the ranges of interest to us, the so-called two meter range and range 70cm, they are not called so by chance, it is the display of wavelengths in the title. These are the frequencies of 137-174 MHz and 420-470 MHz, secondly, as you remember, the household radio shows "soap".

So what is interesting to us 2 meter band think you? And in fact, very many.

The first and very important argument, the rescuers of the Ministry of Emergency Situations work on it.

The second, in this range the huge "army" of radio amateurs is communicating.

The third, it has a good passage in the mountain and wooded area, the 70cm-ryo range wins only in a dense urban building.

Engage in active sports and recreation, it is very stupid to assume that you, your comrade or other people around you, do not need any kind third-party help. Count on mobile phone You can not everywhere, and you have come across it yourself. Therefore, it can be very important to be able to ask. Arriving, in a new area, find out the frequency of the radio stations: guides, voluntary rescue formations and MES. For the Ministry of Emergency Situations, this is the usual frequency of 164.450 MHz, but at what frequency the receivers of local spasprojb and their callsigns are configured, you should find out yourself.

The audio frequency of radio amateurs (usually 145,500 MHz), here are all the surrounding radio amateurs, and many have landline equipment much better and finely configured than in the Ministry of Emergency Situations. You understand yourself, some are so tightened by their hobbies that they are ready to spend huge money and all free time on their passion, to achieve good results. It is also impossible not to note that the radio amateurs have repeatedly accepted disaster signals and transferred information to rescuers, so many lives were saved, at different times.

Taking this into account, we can conclude that have a 2x-meter range in your radio is not very superfluous. The radio stations of this level require registration if you are going to use them on legal grounds. There is nothing complicated in this, but then it is later.

Yasaki-jaisski.

Yaesu. - Brand, well known

among radio amateurs

and is a synonym for high quality

amateur radio stations.

A good combination price \u003d quality just forces to stop more on the models of this manufacturer. Here are three models of portable stations to which pay special attention.

Yaesu ft-60r

Yaesu vx-3r

Yaesu vx-6r

All three stations of two ranges are cost, in the order of magnification.

Briefly about the advantages and disadvantages of these. All of them are very similar in their characteristics.

Yaesu.Ft.-60 R.

Pros: full-fledged 5W transmitter power, price, ability to use: lithium, metalhydride and nickel-cadmium branded batteries, the ability to work from batteries. Dustproof, moisture-proof.

Minus: Large and heavy compared to two others. Not a very thoughtful headset connector, so as not to fly out, have to press the rubber band.

Yaesu.Vx.-3 R.

Pros: very compact and light, 130g. Dustproof, moisture-proof.

Cons: a weaker transmitter, not more than 3W. Only lithium branded batteries.

Yaesu.Vx.-6 R.

Pros: full-fledged 5W transmitter power, compact, medium sizes between FT-60R and VX-3R. According to the requirements of moisture protection, the station complies with the JIS-7 standard (immersion to a depth of 1 meter for 30 minutes). Only lithium branded batteries.

A separate mansion is worth Yaesu VX-120, it is possible to describe it as "feather".

This radio has only a two-room range, but its merits are not in a wide range of reception but in reliability. Waterproof and impact resistant for MIL STND 810 C / D / E Military Standard.

Options for radio stations

Antenna is the best amplifier.

Whatever you have "cool racing"

with a bad antenna, it is not important.

Antennas.

All antennas running with radio stations have very weak characteristics due to their broadband. Since we need antennas for very narrow ranges, you can purchase them and win in quality and range.

Yaesu ATU-6B (420-470 MHz) good antenna for seventies, if you put it at LPD stations, for example, four hundredth Midland, then you will win a great advantage.

Yaesu / Vertex ATV-6XL antenna for a range of 136-174 MHz is configured to the desired frequency by trimming. Card trimming is included in the kit.

Cut it at the frequency of 145 MHz and the second to 164 MHz and get the most efficient antennas for these frequencies.

Opek 601hV Antenna for two ranges 136-174 MHz-420-470 MHz. It makes a slightly greater reinforcement than the standard antenna. Chlipcota, requires a careful relationship, is very shred in place of articulation with the coil. Recently, very unstable quality. With small home improvements shows a bit top scoresthan standard antennas for FT-60 or VX-6.

When using radio communication at a considerable distance from each other, the use of antennas configured to the frequency on which you are working must, since when using standard multi-band antennas, the Will is a chance to be without a connection or take li scraps of phrases.

Garnituts - Tangers.

Headsets or Chief Handsfree are very convenient that they free your hands from the radio station, but you can also quickly carry out the reception of information transferred to you.

The tangent is a remote block on a wire connected to your warning with a microphone, a speaker and a transmission button. Also, in most cases, it has several headphones.

Very comfortable, regardless of station type. The radio may be in the inner pocket (for example, so as not to the murcles) or in a backpack, and the tangent is displayed at a comfortable place and connected to the station with a twisted wire.

Batteries

Batteries are different: lithium, metalhydride and nickel-cadmium. Briefly about the advantages and minuses of them when used in radio stations.

Lithium - have the largest container, with modest size of the battery. Accordingly, long energy flow. The minus they are that they are very afraid of negative temperatures, quickly lose the voltage and the ability to continue working.

Metal hydride batteries have a smaller capacity under the same size, and not so much to be afraid of negative temperatures as lithium. Do not have the "memory effect" can be recharged without waiting for complete discharge. But they have a relatively high self-discharge current. This means that they lose the charge when they are stored waiting for commissioning. In one week of storing a charged battery, you lose somewhere about 20% of the capacity, respectively, 20% of the work time.

Nickel-cadmium batteries have the lowest capacity of the above listed. Can give the most greater current. Possess the "memory effect", require full discharge before new charging. But their advantages in low self-discharge current. Therefore, they still enjoy the attention of operational services.

Battery cassettes

Convenient devices for finger batteries type AA. Can hardly help you find a socket to charge the station there is no possibility.

Cons: Because of the many intermediate contacts between the power elements (batteries), a micro resistance, which prevent normal current-turn, the station will not work on complete swollen and as long as long as a regular battery. Insert the palter batteries larger tank and use it instead of a regular battery is also not beneficial because of micro resist. It is necessary for all connections to prescribe short (about 10-15mm) and thick wires. Well, this is a completely different story.

Increased radiocommunication ranges within the group in a given area.

If the area of \u200b\u200byour interests is around the static object, (house, waggered, a tent camp and the like), then there you can put a stationary basic antenna with good characteristics Reception (for example, Diamond X-50) and take the reception to a small portable station connected through an adapter. plays to install a large power of the transmitter and a more sensitive receiver, which is equal to the best reception weak signals (for example, the automotive FT-2800 on the "Two" or FT-7800, FT-8800 on both ranges), but in both cases use thick wires (7-10mm) with a small attenuation coefficient to the range you selected.

If such a "base" is, and there is no person in it, everyone diverged around yes, and from one portable station to another it is impossible to do with a distance or relief of the terrain. It is possible to connect the Echo Repiter (parrot) to the "basic" station, which represents a small digital tape recorder, on average for 60s records. Connected instead of tangents to the station.

It works very simply, writes a voice accepted on the basic station, at the end of the reception translates the station to the transmission mode and reproduces your words on the ether. You hear you yourself and the correspondent that is not available in direct radio visibility. He answers you and the cycle repeats the required number of times. The cost of such devices is comparable with the cost of two simple or one good "soapy".

Frequencies for work on the air.

2 meters - 144-146 MHz

Here is a small illustration, preferring frequency distribution in the 144-146 MHz band.

From the beginning of what frequencies you should not work, let's say during skiing or boards. Do not get up on frequencies that are marked with color other than green, in the signs above. You can prevent other participants in the ether, and they, in turn, will interfere with you. Do not create discomfort to each other.

Where you can, as you probably guessed, on those frequencies that are marked green, but there are several reservations. The frequency is 145.500 and two frequencies on the right and inland are emphasized, usually used by radio amateurs for local communications with each other. Therefore, do not occupy these frequencies too. There are 25 frequencies in the range of two meters, among which you will definitely choose free. Be respectful and polite with all theirs of Ether, and everyone will be polite with you.
