Portable Motorola walkie-talkies are on the marketin a wide range, thanks to which the technique of this brand is used in various fields of activity - from security companies to recreation, hunting and fishing. Compact radios of the PMR range are the most convenient for radio communication, since they do not require permission from Rossvyaznadzor. For their correct choice, it is worth to rely on the results of testing, for which Motorola portable portable radios were selected.
Why choose a Motorola radio?
For almost a century of existenceMotorola maintains an excellent reputation among consumers. The quality of products is constantly being raised by engineers working to reduce the dimensions of Motorola radio sets while maintaining the power and quality of the signal.
Motorola radio stations attract consumers with an excellent price-performance ratio and wide functionality.
To date, the company is focused on the development and production of new models of radios.
Motorola T80
The simplest and most popular are walkie-talkiesMotorola series T3-T8. They belong to the economy class: the E4 model can be purchased for 1300-1800 rubles, the set of T6 - for 1500 rubles. Model T3, however, will have to look second-hand, because it was removed from production a few years ago.
Walkie-talkie Motorola T80
High quality, reliability and protection fromThe impact of weather conditions is what Motorola's radio model of this model is different from. The waterproof case, a wide range of functions and a communication radius of up to 10 kilometers make it possible to use the radio station under extreme conditions and to stay in touch anywhere in the world.
Using the Motorola TLRK TR 80 Extreme Walkie Talkiedoes not require a license. The radio station is equipped with a liquid crystal display, it can support the operation of 8 communication channels and transmits the signal at a distance of up to 10 kilometers. Built-in LED flashlight and moisture-proof housing allows you to use the Motorola T80 radio in any situation.
Features of radios
Motorola models of the T3-T8 seriesthe electronic base is the same, since they are equipped with the same microprocessor, which explains some similarity in characteristics and disadvantages. Only T6 is different, it is more convenient to operate and attractive in appearance.
If compared with analogues of other brands, then withMotorola devices are comparable to the Jet mini, Vortex and Midland, and some of them are inferior to Motorola in technical specifications and outperform in price.
To exchange messages in the radio it is enough to configure all the radio stations used for one frequency and make sure that all the devices are programmed to the same subcodes.
As a battery for the Motorola TLKRT80 Extreme can be used as 4 AAA batteries connected in series, as well as a nickel-metal hydride battery with a capacity of 600 mAh and a voltage of 4.8 V. The “little pinky” batteries are installed in a special compartment of the walkie-talkie.
A battery, like AAA batteries,it is installed only when the power is off, otherwise the radio may fail. Models T6 and T8, unlike other models, can be charged both in the “cup” of the charger and separately - only with a rechargeable battery, which is installed using special plastic inserts in the “cup”. Other models do not have this feature.
In earlier models - T3 and T4 - were usedsuch accessories and headsets for Motorola radios, such as a detachable clip - holder, a streamlined body with an original design, a multi-segment display-indicator, ergonomic control keys.
Charger and walkie talkies
The set includes the IXTH4016A charger, equipped with a special two-way glass and a power adapter with a maximum current of 300 mA / h and a voltage of 9 V.
Total energy consumption of a discharged batteryconnected to this charger, recovers in 2-3 hours, which is a very good indicator for radios of the same class. The instructions to the radio, Motorola indicates the time required to fully charge the battery - 16 hours. This discrepancy between theory and practice is explained by the fact that in the glass the LED red indicator is on as long as the walkie-talkie is in the charger, and the degree of battery charge does not affect its performance.
On the side panel of each radio is included in the kit, there is a power connector designed for an external source with a voltage of 9 V. Direct current is used.
In terms of power management, the Motorola T6 compares favorably with its predecessors, the T3 and T4 models. Despite this, she has her minuses.
Range of radios
In the passport data radio the manufacturerindicates the range. With a power of 0.5 W, the maximum communication range between two stations of the same model is from 5 to 10 km, depending on the particular radio.
Communication range varies on the intersectedterrain and in the city, as well as in buildings between floors, and reaches a maximum of 500 meters. Similar inconsistencies specified in the passport data are detected when testing on the ground of any other Motorola radio stations.
On Motorola's Wide-Functional Walkie TalkiesVarious data are displayed, including battery charge level, channel number, subcode (if enabled), and other modes activated and used by the user.
Features work with subcodes radio
In portable radios operating in the PMR range,One of the useful and separate functions is the subcode, intended for traveling in nature, tourism, radio exchange at short distances within the city limits - for example, between neighboring houses or apartments.
Subcode programming allowseliminate interference and clear the radio from listening to other radios operating on the same frequency. In Motorola T3-T8 series models, you can set 121 combinations of different subcodes on eight channels available - 83 DCS codes and 38 codes in CTCSS format. In general, a value of 968 different combinations is available.
Each of the mentioned models is equipped with a modeScan all available channels - 8 for each of the radios. The device automatically stops scanning on the channel on which any radio exchange is performed. The suspension of a general scan is signaled by a sound signal, after which reception, that is, listening to the broadcast frequency, is turned on.
Common to all models flaws
In data transfer mode for all Motorola radiosoverload protection is activated. In practice, this is done in the following way: after the continuous work of the radio in transmission mode for 60 seconds, it is automatically turned off. Before stopping work, a flashing “transmit” mode icon appears on the display and a loud beep sounds. The icon on the display is lit without blinking if the device is functioning normally, without temporary overloads. The security mode used in Motorola’s walkie-talkie protects the transmitter's output stage from malfunction and failure in the event of overload and overheating. This element on high-frequency power transistors is the most expensive and difficult to design.
One of the drawbacks of the Motorola walkie-talkiemodels T3, T4 T6 and T8 is the limitation of the signal transmission time to one minute. Repeated airing is possible only with a break for a few seconds. Such a device does not allow to transfer large amounts of information to another correspondent, however, with such purposes, the Motorola radios are used extremely rarely.
In the passport data and on the device box, the communication distance is indicated in ideal conditions: in clear sunny weather with perfect visibility of subscribers at a temperature of 20 aboutWith no precipitation and in the absence of noise liketrees, buildings, power lines. This parameter is theoretical for the specified wavelength - 70 centimeters. When the signal power is 0.5 W, the actual communication range in the forest is 2–3 km, in the field - 3–4 km, at the sea - 5–6 km, in the urban area - 500–600 meters, which is standard for any PMR radio stations brands and models.
Motorola radios compare favorably with theiranalogues of other brands with better technical characteristics and more affordable cost. The communication range of standard devices is sufficient for transmitting and receiving data in extreme conditions.
