Correct tuning of the walkie-talkie makes it possible to optimally maintain contact at a given distance, regardless of weather conditions, mobile coverage or terrain. A similar system operates thanks to radio waves on different bands. A significant role in the operation of the device is played by its competent adjustment. To do this, it is necessary to study the attached instructions and take into account the features of the device (some of them have a narrow specialization: railway, hunting, car options).
Recommendations
Setting up a walkie-talkie of any type involves adjusting the supply and reception of signals at a specific frequency. Otherwise, amateur or professional modification will work at incomplete power or with interference. The most modern modifications are automatically configured, do not require special adjustment. However, they are more expensive. Other models are divided into portable or stationary devices. The arrangement and adjustment of both options is approximately identical, although there are some peculiarities.
Tuning Baofeng walkie-talkie
Below are recommendations for setting up the Baofeng walkie-talkie. For a UV 5R model, the default operating frequency is 2.5 kHz. Standard adjustments are comparable to similar recommendations for most portable radios. Programming simplex channels of the device consists of the following steps:
- First, switch to VFO A.
- Then use the Band key to select VHF.
- In the main menu, the '27' icon is activated, after which the menu option is pressed.
- Further, the information is stored in a free memory location, which can be found using the UP / DOWN keys.
- The selected range is fixed by reactivating the menu button.
- Exit by pressing the Exit key.
To configure the walkie-talkie UV 5R in the part of channels with a repeater shift, the following manipulations are performed:
- Switch to VFO A.
- Select the UHF or VHF option using the Band key.
- Maintain a suitable receiving frequency.
- In the menu section, they find the '27' icon, after which they re-enter the menu.
- A free memory location is selected.
- The final selection is confirmed by another press of the “menu” key.
- To exit, use the EXIT button.
- Once again, the “menu” is activated, where the '27' icon is selected, after which the “menu” is pressed twice.
Features
Tuning an amateur type walkie-talkie is usually carried out in the range 433-434 MHz. These devices do not require registration in the center of radio frequencies, therefore, their adjustment does not constitute special problems. For users who want to increase the power of the device, models are available on the market that are equipped with an additional antenna. In order for the radios to work among themselves correctly, it is necessary to set the same values for numbers and a special code on each instance.
After making the specified settings, you will get devices that will work seamlessly. To start a conversation, press the talk button. After deactivating the button, the device goes into standby mode . Important: setting up a portable type walkie-talkie provides for the selection of an individual callsign. It can be a letter or digital cipher, unique to the selected type of communication.
Kenwood
Using the example of this manufacturer, we will consider the adjustment and installation of a stationary type walkie-talkie. Initially, it is necessary to fulfill a number of requirements that contribute to increasing the efficiency of subsequent operation of the device, while minimizing the possibility of failure of the transceiver. The station itself is a unit installed in the passenger compartment of the vehicle, equipped with an external antenna. In many ways, tuning the Kenwood walkie-talkie of a stationary type depends on its proper installation.
Basic installation rules:
- Do not mount the element on the bearing parts, it is best to do this on the body. This solution reduces losses in the transmission and reception of the signal.
- It is advisable to mount the antenna at the highest point of the body, which increases the quality of reception.
- The working part of the receiving device should be located at a distance of not less than 0.5 meters from other parallel metal surfaces. This will make it possible to level the absorption of the incoming pulse.
- The magnetic antenna must be fixed in a stable position, providing the most stable reception and data transmission.
Megadget
This is one of the most famous manufacturers of stationary walkie-talkies. All the nuances of the settings can be found in the manual that came with the kit. The following are key recommendations:
- First, the “240 channels” mode is activated. The key combination AM / FM-ON is used for this. The Russian signal transmission grid is selected by turning on the DW / M2-ON. It should be noted that most European channels end with an index of 5, while domestic waves at the end have the number 0.
- The radio is turned on via the VOL / Off toggle switch, after which the desired volume of information transfer is set.
- The SQ control optimizes noise reduction.
- The desired channel is selected using the UP / DN keys.
- The gear mode is adjusted using the PTT switch. The optimum distance to the microphone during setup is 5 cm.
- Reception of information is carried out by releasing the tangents, after which a received message is listened with the ability to adjust the volume and level of noise reduction.
Motorola TKR
Below is a brief instruction on setting up the radio of another well-known manufacturer:
- To turn on the device, the Menu button is pressed and held. Adjust the volume by adjusting the arrow keys.
- When you press the buttons, the radio makes a distinctive sound. To deactivate this sound, press the “Menu” key 5 times, after which the tone indicator will flash. Activating the up arrow turns on the sound, the lower analogue helps to turn it off.
- Negotiations with another walkie-talkie become possible after pressing the PTT key. She is kept pressed, the conversation is conducted at a distance of 50-80 millimeters. Releasing this button implies the inclusion of a response message reception mode.
- You can study additional options of the unit in the menu item, which presents all the possible options for the operation of the device.
UV 5R
The station in question is a compact walkie-talkie with many functions for negotiating. More detailed information on channel setting, monitoring, voice control and other options is provided in the user manual.
Radio antenna setup
It is advisable to use a professional analyzer to tune the antenna. In its absence, the most often used KVS-meter. All manipulations are performed on a clean and even surface, away from potential interference in the form of concrete or metal structures. In addition, there should not be similar devices nearby whose operating range is 27 MHz.
After connecting the FAC meter, measurements are taken on the grids and channels. This makes it possible to display an extensive reception picture. Next, the calibration of the FAC meter is carried out by switching the toggle switch to the FWD position. On the device itself, the range at number 20 is set in AM mode. Next, the talk button is activated and held. Synchronously rotate the CAL controller clockwise until the walkie-talkie pointer is at the far right (SET).
Further tuning of the walkie-talkie channels is done by switching the FAC meter toggle switch to REF mode. At the same time, the button on the tangent should be kept pressed. Then the information that the device gives out is taken, the minimum of the pic meter is determined, the antenna is adjusted to the required range. In case of overestimating or lowering the required limit, the antenna is made shorter or longer. Control measurements are repeated until the coefficient of picnic coefficient is less than 1.5.
It is worth noting that the lower the FAC, the better the transmit and receive power of the pulse. Ideally, the coefficient should be close to unity. However, to achieve such an indicator is almost impossible due to the presence of various interference. If the value exceeds 3, the transmitter cascade and the entire apparatus are likely to fail.
Channels for truckers
It is difficult to imagine modern long-distance freight transportation without walkie-talkies. They help to correct the route, report on road and transport problems. In order for the device to work reliably, it is necessary to correctly configure it. As a rule, it is produced in the following sequence:
- An antenna is mounted on the central part of the roof, the protective cap is removed, the adjustment screw is fixed to the limit.
- A pic meter is connected between the walkie-talkie and the antenna.
- The device turns on, then the long-range mode is set (usually this is channel 15).
- Press and hold the tangent, while bringing the FAC knob to the SET position.
- Then the handle is moved to the REF position, the current value of the unit will be displayed on the upper part of the scale. The coefficient using the adjusting screw is adjusted to an indicator not higher than 1.5.
- The control screw is fixed by means of a lock nut, a protective cap is put on, and the information of the FAC settings is additionally checked.
When setting up a walkie-talkie of this type, keep in mind that this device belongs to narrow-band devices, and therefore it is better to make settings on the main wave.
Finally
The setup of the Baofeng UV 5R radio and its analogs is described above. This process is one of the most important factors affecting the efficiency of use of the device and its performance. It should be noted that when choosing a station, consider its main purpose. In today's market, one can easily choose amateur models, as well as analogues for hunters, tourists and people whose specialty requires constant communication, regardless of location and cellular coverage.
