Advice 1: How to set the radio to the same frequency

In order for the users of the radios could communicate with each other, their devices should be tuned to the same frequency. Method of implementation of this configuration depends on the design used by radio stations.
How to set the radio to the same frequency
Instruction
1
First of all, make sure that you use a walkie-talkie approved for use in the country where you live. In the Russian Fedethe radio 's station standards LPD with a power output of 0.01 watt and PMR with the output power of 0.5 watt. Recently (November 2011) they are joined by the radio standard CB radio with output power up to 10 watts. All of these radios simply purchase and register them is not necessary. Also in our country you can use radio Amateur bands, but only after a rather complicated procedure of obtaining a call sign and category.
2
Before you can set up a station on a particular frequency and to operate on this frequency for a transmission, make sure that this frequency is in the range of work where it is allowed. Station with a fixed set of channels are usually arranged so that to set them on undiepatrol frequency just fail. But there are exceptions. So, some expensive radios standard CB channels overlap part of the Amateur 28-megahertz range. To work on these channels for transmission without permits is prohibited. If the Amateur station rebuilds it usually smoothly or in small steps, and the set of frequencies and the capacity in which you are allowed to work depends on so-called category.
3
Also important aspect. If your station is a multi-band, and the antenna is designed only for a specific range, work on it for transmission in other bands is not strongly recommended, even if you have that right. The radio can be damaged the output stages of the transmitter.
4
If the radio has a smooth tuning around the band with the help of the Vernier, set it to a frequencyclose to the one that is configured in the friend station. Let the owner of something transfers. At this time, working on reception, set up his station rather by the maximum signal (with amplitude modulation), distortion (frequency modulation) or natural sounding voice (when SSB modulation). In the presence of pen the exact settings and be sure to use it.
5
Station with analog tuning can be equipped with a so-called numerical scale. If it is, the installation of the working frequency is greatly simplified: just make the indicator corresponding to this frequency. As comfortable and optical scale, almost not conceding on the accuracy of digital.
6
Station with frequency synthesizers typically allow you to enter this parameter in several ways. If the frequency is exactly known, enter it directly with numbers from the keyboard. Or, set up a station so called the encoder - an electro-mechanical emulator knob. The frequency is displayed on the screen.
7
Station with a fixed set of channels set using the arrow buttons. One of them reduces the number of channel, the other increases. The instructions indicate which channel number corresponds to which frequency.
8
If a station has a fixed setting on one channel, communication between two such devices is possible only in the case that these channels are the same. Some imported single-channel station the release of the early nineties is calculated on use of replaceable quartz resonators. Be sure to turn off the radio before they change.

Advice 2 : How to set the radio

For people who lead an active lifestyle, and sometimes need a portable radio. To this class belong primarily the radio, which do not require special permissions that you can register without too much difficulty and documents. They operate in the frequency range of 433 MHz. Such radios are particularly popular among hunters or tourists, and is also useful for fishing. So it's not to overstrain the voice, and the probability of getting lost is greatly reduced.

1
Amateur radio is quite simple to set up.

Don't start with redoing the radio under the Russian standards. Most likely, your radio already has the ability to work in "Russian grids", in addition, the parameters may be affected during the migration.
2
Select to the beginning of the call, the so-called personal identification signal. Formally, it must match the number of your permission for the use of radio. If informally, then just take any digital or alphanumeric alias. Select a word consisting of 6 letters, the interpretation of which will be clear and unambiguous, which is easy to disassemble, if the reception is not very confident. Make sure that none of your friends choose for themselves the same Callsign.
3
In order to tune the antenna, use instrument called the SWR meter. Without it you simply can not do. At first approximation, adjust the antenna for minimum value of standing wave ratio (VSWR). Make sure that the coefficient is less than 1.5.
4
Remember that if you are a long time to work if the SWR >3, it is easy to damage the cascade of the transmitter. Click on the microphone button and adjust the dish according to the maximum illumination of the LEDs.
5
If everything is working correctly, proceed to the range to 160 meters. If you plan to communicate with the owners of such radios, then further configuration can be considered as virtually completed, and if your desire of communication are expanded to users of other radios, try to find a used band strip and connect within.
Useful advice
Professional radio best to set together with specialists.

Advice 3 : How to set a car radio

Automobile radios are a great communication method between vehicles. These devices are very relevant for truck drivers, drivers of passenger transport and for other car owners which often move around the track. They help not only to warn other road users approaching the traffic police patrol, but also to help the driver to call for help if necessary.
How to set a car radio
Instruction
1
Purchase car radio. If your car is provided a niche for its installation, you can easily put it there. If no, it is set in absolutely any place. Thus it should be easily accessible and have excellent ventilation to prevent overheating of the device.
2
Do not mount the radio , where is the path of the air flow from the air conditioner or stove. Quite often the radio is mounted under the glove box or between the seats of driver and passenger.
3
Determine the most convenient from your point of view, a place to mount a car radio there and mark the holes to install the mounting brackets. It is supplied with the device. Don't forget to think about protecting your radio from theft. It may have a removable slide or be embedded in front panel.
4
Drill holes for fasteners. Before you start drilling, check to see whether you relate to the wiring of the car. To restore it after damage does not always work easily and quickly.
5
Determine what your automotive radio power supply. If the wrong connection of the radio to a power source will decrease the output power of the device. It is best to connect the radio to the battery directly, namely, to its terminals (plus and minus).
6
Use to connect the radio to the powered copper wire. Eliminate crossing the power wire with the alleged sources of interference. Use a shield made of ferromagnetic wire, which is protected from oxidation.
7
Select the correct installation location of the antenna after mounting a car radio in the car. Ideally, you'll be able to put the antenna on the roof in the center of the cab. Connect the antenna and the radio.
8
The setting of the equipment trust professionals.
