How to choose a walkie-talkie?
Practically every person in life had a situation when communication was required - on holiday in the woods or during a long drive. Cell phone does not always help, but the radio will become an indispensable thing for such cases. This article will tell about how to choose a walkie-talkie. Today, the production of communications does not stand still. New technologies are being used, digital methods of controlling and processing signals are being introduced - all this creates a wide range of radio communication capabilities. In Russia, more than 60 radio channels are allowed for widespread use. This causes the presence of a specific set of channels in many radio stations. If, for example, a tourist group decides which radio to buy for future use in a hike, then they will need to choose the one in which each member can be assigned a separate line, thanks to multi-channel.
What to consider when choosing a radio
- Acquisition goals - to ensure, for example, the connection of cars on the track, you should first determine the desired distance,This will help resolve the issue range.
- Intensity of use - sporadically, once from a time, or constantly.
- Compliance with communications legislation.
When deciding how to choose a walkie-talkie, we must remember that there is no perfect, or universal, radio station. Because for use in fishing or in the service call a taxi, the radios will have a different radius of action. It depends on the following factors:
- Frequency range
- Walkie talkie
- Radio quality
- Use in automobile and base radio stations KSW (KSV) antennas.
Radio stations for urban environments
For example, for use in urban environments, you should buy a walkie-talkie in an auto base exactly the one whose power will not be affected by the density of the settlement, and which will have the necessary range. Ready base radio station is not a bargain, because very expensive and it is not designed to increase power. It is best to independently assemble the base station from the following components:
- Car radios
- Amplifier (BUSTER)
- Power Supply
- Base antenna
- RF cable drop
The radio standing on the car should consist of a car radio station and a car antenna. There are many proposals for choosing an antenna for the radio. Starting from the simplest and cheapest “fishing rods” to the longest and most expensive ones. The main thing is to determine the power (400 - 600 W), with the gain (1.3-5.5 dB) and the installation, which can be with a magnetic base and mortise. Simply put, a longer pin length will provide a better connection.
Shops and markets that sell mobile phones often offer “walky-talky” kits. They are inexpensive and easy to use. Such radios are perfect for negotiating at a short distance, for example, between a warehouse and a supermarket hall. But in more severe conditions, these radio stations will not provide you with high-quality communication, because not protected from external influences such as moisture, dust, falling from a height.
Builders, road services and housing offices, i.e. working in urban conditions, preferably choose a range that breaks through metal structures, brick and reinforced concrete. This range is from 400 MHz. For distances from half a kilometer the radio stations will be suitable for low power, from manufacturers such as Midland, Icom, Vector.If the required distance from 3 km within the city, which is important for security companies or escort cars in the city, then the radios are needed more powerful - Vertex, Kenwood, Icom, Motorola.
Radio stations for natural conditions
When purchasing a radio station for communication in open spaces, which are preferable for fishing, hunting or just outdoor recreation, it is best to choose the low-frequency range from 140 MHz. They are allowed for amateur use. The wavelength of this range is better bypassing the standing obstacles in the form of hills, bushes, trees or pillars. Professional radios are better, from manufacturers such as Vertex, Kenwood, Turbo, Icom, Motorola, Roger, Midland, Linton, ViaRadio.
If you are going to conquer large bodies of water, then the VHF range is ideal. The radio stations operating on it will strike any obstacles, not only in the form of forest and land, but also a large water column. Morflot chooses this range for work. The radios, working on it, are distinguished by high moisture resistance, impact resistance and dust resistance. They can also be equipped with a headset, which is useful both at rest and at work.It will not be superfluous and a cover that will protect against possible unpleasant situations.
There are good options for walkie-talkies that allow communication in the forest and in the city. This saves you from purchasing two different sets. For example, the manufacturers of the amateur radio Vertex FT-60R made it possible to work in the lower and upper ranges, i.e. from 140 MHz to 433. If you suddenly decide to buy a walkie-talkie for hunting, but at the same time you would like to use it in the city, then such a modification is perfect for you. If you find a failure in her work, if yesterday she worked perfectly at the dacha, and today she stopped working at the supermarket, you just need to switch the range. Now you know all about choosing a radio. This can pick up a really necessary thing for you. We wish you a happy shopping!
