We present to your attention a new ergonomic walkie-talkie Ajetrays AJ 446. Like the older model portable radio AjetRays AJ-344, the Ajetrays AJ-446 is certified in Russia. The mere fact of having a certificate does not guarantee the quality of the product, but speaks of the seriousness of the supplier and concern for the consumer. The fact is that the presence of a certificate automatically removes a lot of questions for the user from the radio frequency center and other inspection authorities.
The new Ajetrays AJ-446 radio station has many functions and a maximum transmitter power of up to 3.5 W, but first things first...
Appearance, controls, ergonomics
Station AjetRays AJ-446 has a classic strict design and a minimal set of controls. The radio is based on a high-strength metal chassis, which ensures the reliability and durability of the structure. The case is made of high-strength plastic, has a rough surface, pleasant to the touch and does not allow the transceiver to slip out of your hands. Under the speaker slots, there is a fabric glued on the inside of the speaker grille, which prevents debris and dust from entering the station case.
The AjetRays AJ-446 radio station is equipped with a Li-Ion rechargeable battery with a capacity of 800 Ah. Combined with the supplied quick charger, the battery provides enough runtime for a shift.
On the top panel are: indicator light, SMA-type antenna connector, 16-position channel selector and volume control knob / turn on the radio station.
An interesting feature of this model is the sounding of the channel number when the radio station is turned on or when the channel is changed. A female voice announces the channel number on English language with a slight Chinese accent. Probably, in the near future we will receive a Russified version of the sound. At least the latest Soontone-518 models "speak" Russian. This feature may be disabled or selected in "English" by your dealer or distributor. If this feature is disabled, there are no messages when the radio is turned on or the channel selector is rotated.
Sounding channel numbers seems to be more of a useful feature than a marketing "chip", since it is rather difficult to distinguish between small numbers printed under the channel number selector knob, and only odd channels have markings. In the dark or in low light, you can determine the channel number in the absence of this function only by the number of clicks of the selector, turning it first to the leftmost position and counting the channel number, starting from the second.
The belt clip has a spring-loaded design with enough spring force for a secure fit and plenty of travel for comfortable use. The upper tongue of the clip is equipped with an eyelet for attaching the strap to the wrist. Such a design, in my opinion, is not entirely reliable, since the load from the strap is transferred to the clip, from the clip to the battery, and from the battery to the body of the station. However, the complete absence of backlash of the battery and clip, as well as the high quality of the plastic, make this drawback insignificant.
Like the older model AjetRays AJ-344, the AjetRays AJ-446 comes with a flexible 13 cm long antenna. This antenna design, combined with a threaded antenna connector fixed directly to the metal chassis, provides this vital radio station with maximum reliability.
Functions and modes of operation
The AjetRays AJ-446 radio station has a minimal set of controls, which corresponds more to the professional purpose of the device than to an amateur one. A sufficiently large set of functions can be programmed from a computer. Moreover, the functions will be controlled by changing the channel or by the only functional button located under the PTT button.
The function button can be programmed to perform one of the following functions:
Key lock / Key lock and backup. Holding down the function button for 1 second will lock/unlock the radio buttons and channel selector. If the button is programmed as "Key lock and backup", the lock will work until the radio is powered off.
Monitor. After pressing the button and a confirmation sound signal, the Ajetrays AJ-446 radio will switch to the signal reception mode without programmed CTCSS or DCS codes. In other words, this is a function to turn off the code squelch. To return to the mode of operation with code subcarriers, press the button again.
Monitor momentary. The function is similar to the previous one, but the code disable mode is active only while the function button is held down.
Squelch off. Disable squelch. During the activation of the function, ethereal noise will be heard. Used to receive very weak signals that are interrupted when the squelch is on. The transition to the normal mode is carried out by pressing the function button again.
Squelch off momentary. The function is similar to the previous one. Hold down the button to listen to ethereal noises. This feature is programmed by default.
Scan. Scan is a signal search function on all channels. While scanning, the radio checks for a signal on each channel and stops on the channel that has a signal. The radio remains on a busy channel until the signal goes out. Press the function button to start scanning. Scanning is performed by searching channels, starting from the current channel in ascending order of channels. To stop scanning, press the button again.
Priority Scan. If a priority channel is programmed into the radio, the radio will automatically switch to that channel when a signal appears on it, even if there is also a useful signal on the current channel. The radio will remain on the priority channel until signal loss and after signal loss, for the programmed delay time. The scan will then resume.
Scan+temporary delete. "Temporary exclusion of a channel from scanning", that is, the ability to temporarily remove a channel from scanning. When the scan is stopped on a channel, the channel can be removed from the scan by pressing the function button. To return a channel to the scan list, you just need to exit the scan mode, or turn off and then turn on the radio.
Priority channel cannot be removed from scan.
T.O.T.. The transmission time limit timer is designed to prevent one of the users from occupying the channel for too long. If you continuously transmit for more than the set time, the radio will stop transmitting and a beep will sound. Release the PTT button to stop the beep. You can then resume transmission by pressing the PTT button again. The TOT function is programmed using a PC.
Busy channel lock. This function is programmed from a computer. If no CTCSS or DCS tones are programmed on the selected channel, the radio will not be able to transmit if it is receiving.
Tone Squelch (50 CTCSS, 107 DCS). Some channels may be programmed with CTCSS or DCS. The CTCSS or DCS tone is a tone that makes it possible not to hear signals encoded with another tone or without a tone. This is necessary when multiple user groups work on the same channel. If the channel is set to tone squelch, the radio will only receive the signal containing the corresponding tone.
Similarly, the transmitted signal will only be heard by channel users whose receive tone matches your radio's transmit tone. If the receive tone is not set, you will hear all signals, whether they are tone coded or transmitted without a tone.
Battery saving mode. The battery saver function reduces power consumption in standby mode (when there is no reception, transmission and button presses). The radio will automatically enter Low Power Mode 10 seconds after the radio stops receiving or the last time you press any button.
Cloning by cable. The radio allows you to copy all the programmed features of another radio using a clone cable (not included).
The VOX mode declared in the instructions is not implemented in this modification. Perhaps in future versions this feature will be present.
What's inside?
The AjetRays AJ 446 radio station is a solidly assembled device, at the base of which is a durable aluminum alloy chassis. The assembly and soldering of the elements are also of high quality.
The body parts are tightly fitted to each other, which provides satisfactory dust and splash protection. The radio station does not have a rubber seal around the perimeter of the case, which in practice is more of an advantage than a disadvantage. The fact is that it is not possible to provide complete moisture insulation in radio stations of this class. However, some models are provided with a hermetic connection of the body halves using a rubber seal, while they have holes in the body for controls and a speaker. If moisture gets into such a radio station, it accumulates in the lower part of the case, where it causes corrosion of the printed circuit board elements.
The Ajetrays AJ-446 station has a receiver with a sensitivity of 0.2 mV (12 dB SINAD), a transmitter power of 3.5 watts. The weight of the radio station with antenna, clip and battery is only 190 grams.
Who is our competitor?
The closest competitors are the portable stations Vector VT-44 Master and Optim WT-555. One could also mention the Soontone 518 and its variant imported into Russia under the Kenwood brand, but due to its low reliability, this model is gradually leaving the market.
The Vector outperforms the AjetRays AJ-446 slightly in terms of price, but loses in terms of power and communication range, and a little in terms of functionality.
The Optim WT-555 radio is also slightly cheaper, has the same functionality as the AjetRays, which can be controlled using the available buttons and display. Station Optim WT-555 has b about more power (4 W) and also b about Large battery capacity (1100 mAh).
However, most industrial applications require a minimum set of controls and sufficient transmitter power. Then the AjetRays AJ-446 station becomes the only alternative. The radio station is perfect for security guards, employees of warehouses, supermarkets, homeowners associations, builders, athletes, tourists, hunters and fishermen.
Portable walkie-talkie Ajetraize AJ 446
comparative review of AJ-446 v2 remake
In 2010, an updated version was created to replace the AjetRays 446 compact radio model that began to gain popularity. The updated model immediately attracts attention with a modern design, which at the same time inherited the conciseness and utility of the previous version. The body of the radio station has more rounded outlines and smooth lines. From a technical point of view, the new model retains the classic solutions that have become familiar and have passed the test of time.
Appearance, design
The body of the Ajetreise AJ-446 station is made of black durable plastic with a "leather-like" texture. Under the slots of the speaker is a fine metal mesh that prevents debris from entering the body of the radio. In the previous version, a fabric glued on the inside of the grille of the speaker slots protected against the ingress of small debris and dust. It is difficult to say which solution is better. On the one hand, the fabric protects against dust better, on the other hand, in case of peeling from the case, the fabric can rattle and introduce sound distortions in the operation of the loudspeaker.
The shape of the case is made taking into account ergonomic requirements. The body of the Agetraize fits comfortably in the hand, with a slightly flared top and ribbed bottom to prevent the radio from slipping out of your hand. The weight of the radio with belt clip and antenna is 203 g. The previous model in the same configuration weighed a little lighter - 191 gr. Despite this, the mass of the radio is within the limits characteristic of most modern compact transceivers.
The clip is attached to the back of the battery with two screws included in the kit. AT old version the clip was latched with a sled
Antenna
The antenna is quite flexible, has a smooth surface and a rounded top, which will positively affect the usability and ease of removing the radio from under clothing. Compared to the previous version, the AjetRays AJ-446 antenna is shorter by 2 cm and has a length of 11 cm. The antenna connector is SMA “mother” (the old version had a “father”). Thus antennas from older versions are not compatible with the new model. When ordering mobile or fixed antennas, this feature should be taken into account.
Governing bodies
The Ajetraze radio has a classic “right-handed” control layout. The antenna is on the left and the handles are on the right. In this configuration, the radio is comfortable to hold in the left hand, and switch modes with the right.
On the top panel of the radio are a 16-position channel switch, a power/volume knob, and a three-color mode indicator. The channel number font is larger and more legible than the previous version. The channel switch knob does not have an embossed position mark, like the previous version, but only. But the handles themselves are slightly larger. As in the first version, channel numbers are announced in English when switching. The Russian-speaking version has not yet appeared. In general, the switches do not cause difficulties in use.
On the right side of the body of the Agetraz radio station there is a jack for connecting a headset or an external PTT. The connector is protected from moisture and dust by a rubber plug. In the previous version, the plug was made of plastic and was fixed with a screw for a Phillips screwdriver.
On the left side are the PTT button and two additional buttons, the functions of which depend on the programming of the radio station. The PTT button has an embossed pattern and is comfortable to use with both the right hand (forefinger) and the left (thumb). By default, the lower functional button turns on the “monitor” mode (turns off the squelch), and the top one turns on the “Alarm” mode. In the previous version, there was a single functional button responsible for the "Monitor" mode.
The function buttons and PTT are also used to program the radio operating modes. So, for example, by setting the 16th channel, turning on the radio at the same time as pressing the PTT button switches the output power of the radio station transmitter, the lower functional button turns on channel scanning, and the upper one switches the language of sounding the channel number (English / Chinese / mute). Those who wish can learn to count up to 16 in Chinese))).
Battery and charger
The battery of the updated version is also lithium-ion, but has a larger capacity - 1200 mAh versus 800 mAh for the previous version. As in the older version, the battery has a slide at the bottom for charging in a glass separately from the station. By the way, when charging together with the radio station, fixation in the charging cup occurs due to the same battery sled, and a gap is formed between the front wall of the station and the cup. Probably, the enlarged charger socket was made in order to use also batteries with increased capacity and, accordingly, an increased size.
With standard AjetRays walkie-talkie battery Charger can be placed in two ways - closer to the back wall (charge mode) and closer to the front wall (without charge). Despite the seeming insignificance of this feature at first glance, in practice this feature turns out to be very useful. Often, users, using a walkie-talkie in the immediate vicinity of the charger (on the base), every now and then after the communication session return the transceiver to the charging glass. In this mode, there is a "memory" effect, when the battery is not completely discharged, but already ceases to carry the load. Despite the fact that Li-Ion batteries have a slightly pronounced memory effect compared to metal hydride and nickel-magnesium batteries, nevertheless, you should not neglect it. And the term of "life" of the accumulator the constant charge does not increase.
Batteries have different fastening locks and are not interchangeable. AT new version Ajetrays battery is inserted into the slots in the bottom of the radio body and snaps into place on the top with one latch. In the previous version, the battery in the upper part of the radio body was fastened to two latches on the sides of the battery, to remove which it was necessary to press two latches at the same time. It is difficult to say which design is more reliable, but the new version is definitely more convenient.
Specifications
In terms of communication quality, the new Ajetreise AJ-446 is not inferior to the previous version. Good speech intelligibility is ensured by high sound quality, despite the absence of a built-in digital voice processing (compader) function. The sensitivity and selectivity of the receiver are within the same limits as the previous version, which ensures a high level of reception.
As for the output power of the transmitter, it is twice as high for the new station. The declared power of AjetRays is 4W. The output power of the sample turned out to be 5 W. Undoubtedly, this will have a positive effect on the range of radio communication.
The AJ-446 radio has the ability (without programming from a PC) to switch the transmitter power (high / low), which will allow you to use the station in maximum range mode or in battery saver mode. Different channels can be programmed with different power levels.
Programmable Features
The radio station has a wide range of functions programmed from a computer:
- 50 CTCSS/107 DCS coding tones
- channel scan
- priority scan
- transmission limit timer (TOT)
- busy channel lock
- battery saving mode
- "repeater" frequency shift for communication through a repeater
Package contents and compatible accessories

Conclusion
In conclusion, I would like to note that the new version of AJ-446 is in the same price category as radio stations Optim WT-555, Vector VT-44 Master. With a solid feature set, the highest communication performance and a strict utility design, the AjetRays station is an excellent choice for industrial and domestic applications. The radio is perfect for security guards, employees of warehouses, supermarkets, homeowners associations, builders, athletes, tourists, hunters and fishermen.
