4 types of radios: without a license, hunting and mountain, professionals

In life there are times when the radio is preferable to other methods of communication.

Depending on the membership of one group or another, the radio vary in specifications and features of the application.

When purchasing equipment, including that which is considered to be public domain, it is necessary to know in advance which country is expected to use this equipment.

Penalties and fines for use of a device that does not meet the requirements of local legislation, unpleasant surprise of tourists, who had not managed to get acquainted with them. Get the equipment in place in the country where you intend to use it.

license free

Use of such devices without problems, does not register and are not issued, no additional permits. And not have to pay a monthly fee for use of radio frequencies.

Due to its small size, the radio can easily fit in your pocket. They are suitable for mushroom pickers who do not want to keep up with the company in an unfamiliar forest, fishing nearby, or moving in a convoy of motorists.

Operating range specified by the manufacturer, 3, 5, and sometimes even 10 km is rarely achieved (in the documentation indicates the maximum possible distance).

Dense forest, rolling hills, dense urban development have become a serious obstacle for unlicensed devices signal.

Small size and weight mean and low battery capacity, at the most expensive samples rarely exceed 2000 mA / h.

By acquiring this category of device, you pay attention to how it is able to withstand shock and moisture. It will be bad enough if the fall radio in wet grass or on the rocks appliances stop working.

Walkie-talkies for hunting

Model Specifications unlicensed radios do not meet the requirements of the hunter. Such models are unable to provide reliable communication in the forest at the required distance.

You need to purchase device for which you want to go through the process simplified registration. Only then the user will receive a guarantee that the devices have enough power to communicate over a distance of three kilometers and more, in those difficult conditions, which means hunting.

Radio for hunting, must necessarily meet the following criteria:

• Permissible transmitter powerWithin the framework of existing legislation. A common limitation - 4 watts. It is believed that this power is enough to make even in the dense forests to keep in touch at the required distance. Some jurisdictions permit the use of transmitters with a capacity above specified.
• Sufficient from impacts and penetration of moisture protection. hunting members are constantly moving, for hours still lie on the snow or wet grass. Hunter, busy with thoughts of careful handling of electronics, is not able to concentrate on hunting down prey.
• The ability to operate in the desired temperature range. Hunting happens and under the scorching sun, and when the hands get cool in the cold. It requires that in these cases, the communication device worked without a hitch.
• The housing and the display. It is important that the body and placed it on the switches no problems during operation. The display - clear and clearly visible regardless of the lighting conditions.

• battery capacity. It requires a power supply corresponding capacity, which is enough for a long time. Even better, if construction of the device involves replacing the power source, and a spare battery is included.

No radios models exclusively for hunting. Manufacturers do not release such products in a separate group, involves the use of only hunters and fishermen.

Way radios for use in the mountains

Mountains - a test for the radio. However, in the mountains relationship particularly needed. Warning signal, and people in need will provide the necessary assistance. In the mountains, even vital nuggets of information that have reached the destination in time.

As an instrument for the maintenance of security, such devices are selected according to the following characteristics:

• Range and reliability. These parameters are located in the mountains in the foreground.

  Ranked Among the transmitters operating in civil bands in the mountains is better to use operating at a frequency of 27 MHz.

  
  The signal at this frequency is less prone to interference and runs even in adverse conditions.
• Capacity and battery power. These parameters affect the operation of the device, receives and transmits radio signals. First of all, at the time of its use in the operating mode. When you give preference to the purchase of models of radios, albeit cumbersome, but-equipped high capacity batteries. Purchase models capable to maintain operation of the device is not less than forty hours.
• Protect from moisture, temperature fluctuations and high udarprochnost for such instruments is even more important than the models used in hunting.
• noise suppression. Necessary where the likelihood of interference, including atmospheric. If the noise reduction function is not doing its job, then because of some interference caller does not hear your voice, and you will not be able to make out the answer.

Do not forget about the fact that the radio - it is not only a transmitter, but also a sensitive receiver.

Acquiring a model corresponding to the above requirements, you can be sure that in the mountains, you will not be left without communications. In the event of unforeseen circumstances, will be able to come to the aid of the victims, or to catch the rescue, taking sent someone signal.

Professional radio

Way radios are designed to provide uninterrupted communication drivers and law enforcement professionals authorities, builders and doctors - these people need time and receive in full the necessary information. Such devices are more expensive than amateur.

Constant use implies high reliability. These requirements apply to every detail, from the power supply, and ending with the button. Equipment failure and the reason for this serious financial losses and damage to health and even the lives of people.

The quality of communication provided by the professional devices, also higher than that of an amateur. This is possible through the use of powerful and sensitive components, shielded against interference.

According to the range of the professional tools surpass amateur, range up to 100km.

The capacity of the battery more than 2000 mA / h, in some models provided a connector for connection to the power supply network.
