It should be noted that the market offers a wide range of devices focused on universal use or a narrower specialization (automobile, hunting, railway radio stations).

general information

Any walkie-talkie must be tuned to a certain frequency. If the configuration is incorrect, the amateur or professional device will work with interference or at partial power. The latest modifications of digital devices do not require special adjustments, since they have an automatic tuning function. The rest of the devices are divided into portable (portable) or stationary (car) walkie-talkies. The configuration of both modifications has its own nuances, although the general principle is largely similar.

How to set up a walkie-talkie type?

Amateur portable radio stations operate in the range of 433-434 MHz. They do not need to be registered by the radio frequency center, so setting them up is quite simple. If you plan to increase the power of the device, please inquire about the possibility of using a detachable antenna before purchasing. Another important point is the aggregation of radios among themselves. To do this, it is necessary to set the same numbers and subcode on each device.

After carrying out these manipulations, the selected devices will work smoothly with each other. To communicate, you just need to press and hold the call activation key. After releasing the button, the device switches to a signal from another radio. An important point in setting up a portable device is the choice of an individual signal for identification (call sign). It can be any numeric or alphabetic code that has a unique origin for the selected communication system.

Antenna tuning

Let's consider general recommendations on how to set up a portable type walkie-talkie in terms of the antenna. To accurately correct the element, a special analyzer is required. Alternatively, you can use an SWR meter. It will allow you to tune the antenna to the minimum stable wave ratio. Most often, a ratio of 1.5 or less is considered optimal.

It should be borne in mind that the higher the SWR value, the greater the loss of signal transmitting power. Ideally, this parameter should approach unity, but in practice it is almost impossible to achieve such a result. If the FAC exceeds three units, it is quite possible to disable the transmitter stage. From this we can conclude that an unconfigured walkie-talkie can quickly break down.

car modification

How to set up a (stationary) type? Beforehand, it is necessary to perform a number of mandatory procedures that will increase the efficiency of further configuration and minimize the likelihood of damage to the transceiver during operation. The device under consideration is a stationary unit fixed in the vehicle interior and a remote antenna. It is the last element that plays a significant role in the reception and transmission of a signal. Therefore, it is necessary to know the basic rules for mounting a receiving remote device.

Installing a car antenna

It is not allowed to mount the element on load-bearing parts, the body will be the best option. This will protect the air from possible losses in receiving and transforming the signal.

In addition, the following points are important:

  • Try to install the antenna at the highest point of the body. This will improve the reception quality.
  • The working part of the antenna is installed at a distance of at least 500 millimeters from any parallel metal surfaces. This will make it possible to avoid absorption and reflection of the incoming signal.
  • Placement on the roof of a car has a certain effect on the stable wave ratio. Therefore, fix such an element after removal in one position.

After the correct installation of the antenna, proceed to its adjustment.

Setting up an antenna for a fixed radio

To tune the channel of a stationary type walkie-talkie, the antenna is first configured. For this, it is best to use a professional analyzer. If not available, use an SWR meter. Work is carried out on a clean and even surface, away from metal or concrete interference, as well as other analogues of the 27 MHz band.

First connect the SWR meter. Then measurements are made on channels and grids to display an extensive picture. Calibrate the SWR meter by setting the toggle switch on the front panel to FWD mode. Channel number 20 of AM modulation is set on the radio. Then, the talk key is activated and held while simultaneously turning the CAL knob clockwise until the device pointer is set to the extreme right position SET.

Without releasing the button on the PTT, switch the toggle switch of the SWR meter to the REF position. Capture the data provided by the device. After finding the minimum SWR, tune the antenna to the desired frequency. If the limit is lower or higher than the required frequency, the antenna is shortened or lengthened, respectively. Measurements are repeated until the SWR ratio reaches 1.5 or less.

How about a wave of truckers?

Consider this procedure using the Sirio T3 Mag antenna as an example (range within 5 km):

  1. The antenna is mounted on the central part of the roof, after which the protective cap is removed, the adjusting screw is screwed in until it stops.
  2. An SWR meter is installed between the radio and the antenna.
  3. The radio is turned on, the “long-range” mode is set (channel No. 15 on AM).
  4. After pressing the tangent, adjust the SWR knob to bring the arrow to the SET position.
  5. While holding the PTT, move the SWR lever to the REF position, observe the current value of the device on the upper scale. If the coefficient is higher than 1.5, with the help of an adjusting screw, the readings are adjusted within 1-1.5.
  6. The correcting screw is fixed with a lock nut, put on the cap and re-check the SWR readings.

Knowing how to set up a trucker's walkie-talkie, it must be borne in mind that these elements are narrow-band. Therefore, it is better to perform settings on the main working channel.

"Megajet"

First, the radio is switched to 240 channel mode using the AM / FM-ON combination. You can switch to the Russian grid by typing DW/M2-ON. Domestic frequencies end in 0, European waves end in 5.

How to set up the radio "Megajet"? You can do it yourself by reading the instructions. Briefly, the following points can be noted:

  • First turn on the radio with the VOL / Off knob and set the desired sound volume.
  • The SQ control adjusts the noise suppression threshold.
  • Use the UP/DN switch buttons to select the desired channel.
  • To set the transmission mode, hold the PTT control, speak into the microphone at a distance of 50 mm.
  • To receive, release the PTT and listen to the received message, adjusting the volume and squelch level.

"Baofeng"

Next, let's look at how to set up a Baofeng walkie-talkie. By default, the operating frequency of the device is 2.5 kHz. General settings are identical for portable radios. The following are ways to program the device.

Simplex channels:

  • Go to VFO A.
  • Pressing the Band button selects the VHF mode.
  • In the menu, type ‘27’ and press menu.
  • Then use a free memory cell, which is searched using the UP / DOWN buttons.
  • The selected frequency is confirmed by pressing the menu key again.
  • To exit - Exit.

Channels with repeater shift:

  • Switch to VFO A mode.
  • Select UHF or VHF using the Band key.
  • Select a receiving frequency.
  • In the menu find ‘27’, then back in the menu.
  • They are looking for a free memory cell, as in the previous case.
  • The menu button confirms the selection.
  • Press EXIT.
  • Then enter the menu again, select ‘27’, press “menu” twice.

Finally

Above is how to set up the radio. The wave should be selected, depending on the type of device, as well as the country where the device is used. The antenna plays an important role in the configuration of portable and stationary radios. Therefore, its installation and configuration should be given special attention. If the device is adjusted correctly, you will be able to freely communicate with the respondent at the distance indicated in the instructions for the device.

There are many portable and car radio transmitters on the market today. Among them, you can easily choose the option that best suits your needs. It is worth noting that modern digital models are configured automatically, but their price is an order of magnitude higher than the considered analogues.

Modern technologies allow us to always stay in touch, regardless of the place of stay, weather, the presence or absence of cellular networks. All this is possible thanks to radio communication - a type of communication that uses radio waves of different frequencies as a carrier of information. Today, most of the radio equipment market is represented by walkie-talkies and radio stations that can be used as a means of communication for motorists and the military, security guards and hunters, fishermen and skiers. A simple solution buy a walkie-talkie sometimes it saves in difficult situations when you need to call for help or convey particularly important information. But not always, it turns out, to achieve excellent signal quality for receiving and transmitting a walkie-talkie.

This is largely due to the fact that the selected radio must be tuned to the desired wave. That is, initially any walkie-talkie, whether amateur or professional, may not work at full capacity or work with interference. Modern digital walkie-talkies do not need to be tuned, as they have a built-in button that allows you to automatically adjust the device to the required radio wave. The remaining walkie-talkies can be conditionally divided into portable (wearable) and automobile (stationary). Setting up walkie-talkies These two types are similar in many ways, although they have their own characteristics.

Setting up walkie-talkies

Portable walkie-talkies in the amateur band (433-434 MHz) do not require registration with an RF center, so setting them up is a fairly simple process. Before buying, you need to find out if the radio supports interchangeable antennas, in case you want to increase the power of the radio. Also, an important point in the operation of portable radios is their adjustment to each other. To do this, on each radio you need to set the same channel number and subcode. Only in this case, the selected radios will work smoothly with each other. To send a message, just press and hold the start button. After releasing the button, the radio waits for reception from another device. An important element of setting up a portable radio is the choice of a call sign (identification of an individual signal). This can be any alphabetic or numeric alias that is unique to the selected radio system.

Further walkie-talkie setup includes setting up the radio antenna. We will consider in more detail the tuning of the radio antenna below for car radios. For now, just note that you will need an antenna analyzer to fine-tune the antenna. But in many cases, to set up a walkie-talkie as a first approximation, a device called an SWR meter is enough. With it, you need to tune the antenna to the minimum standing wave ratio. Generally, an SWR value of 1.5 or less is considered optimal. It is also important to understand that the higher the SWR value of the wave, the greater the percentage of power loss during signal transmission. But in practice, achieving SWR = 1 is almost impossible. If the standing wave ratio is greater than three, then operation in such conditions can disable the transmitter stage. Thus, an unconfigured walkie-talkie can easily fail.

How to set up a car radio

Before as set up a car radio, you need to perform some required steps. They will not only increase the efficiency of subsequent tuning, but also minimize the likelihood of a transceiver breakdown in the future. Usually, a car radio is a stationary unit that is fixed in the car and a remote antenna. It is the car radio antenna that plays a key role in signal quality in many ways. Therefore, you need to know the basic rules when installing a car antenna.

Rules for installing a car antenna

  1. It is not allowed to install the antenna on the supporting elements. Always try to install the car antenna on a load-bearing body. Thus, we will protect ourselves from possible losses in the efficiency of radio signal transmission.
  2. It is important to install the antenna on the highest part of the body, usually the roof. The higher the antenna is installed, the stronger the signal.
  3. The antenna web must be installed at a distance of at least 0.5 meters from any metal surfaces parallel to the emus. This will prevent possible reflections and absorption of the signal.
  4. The position of the magnetic antenna on the car roof has little effect on the standing wave ratio. Therefore, always try to fix the magnet in the same position after removing it.

After the antenna is properly installed, it must be tune. Only after tuning the antenna can you safely use the radio at full power.

Setting up a car antenna

The best way to tune your antenna is to use a professional antenna analyzer. But since the prices for such devices are quite high, many motorists find an alternative in SWR meters. With this device, you can adjust radio antenna in the first approximation. This is what the simplest SWR meter SWR-430 looks like

So, antenna tuning must be performed on a flat and clean surface devoid of any interference: metal, wooden or concrete objects. It is also important that when setting up the antenna there are no other 27 MHz antennas nearby. Armed with an SWR meter, you can begin to tune the antenna. The first step is to connect the SWR meter between the station and the antenna in a special way (as shown in the figure below).

  1. It is important to take measurements on different channels and grids to see the big picture.
  2. We calibrate the SWR meter. To do this, set the toggle switch on the front panel to the FWD position. We set the AM modulation channel 20 on the radio. After that, we press and hold the button to start the conversation, while turning the CAL regulator clockwise, so that the arrow of the device becomes in the extreme right position SET.
  3. While holding the button on the PTT switch, switch the toggle switch on the front panel of the SWR meter to the REF position. We take readings of the device.
  4. We find the minimum SWR and tune the antenna to the desired frequency. If the minimum is below the required frequency, then the antenna is shortened. Conversely, if the minimum is higher than the required frequency, then the antenna is lengthened.
  5. All manipulations are performed before re-tuning the antenna.
  6. We repeat the measurements until the result is achieved (SWR is not more than 1.5)

As mentioned above, achieving SWR = 1 is largely problematic, precisely because of the characteristics of a particular antenna-body pair. But even if SWR = 2 in the desired section of the radio frequency range, the loss in efficiency will be no more than 10%. That is, for comfortable communication and transmission of messages without interference, SWR = 1.5 is quite enough.
