Sale of Ajetrays AJ-446 walkie-talkies is possible with delivery throughout Moscow, as well as pickup from the point of issue.

To replace the portable radio model AjetRays AJ 446, which began to gain popularity, an updated version was developed in 2010. The model immediately attracts attention with its modern design, which at the same time inherited the laconicism and utilitarianism of the previous version. The station body has more rounded outlines and smooth lines. From a technical point of view, the new model retains classic solutions that have become familiar and have stood the test of time.

Appearance, design

The AJ-446 case is made of black plastic with a leather-like texture. Under the speaker slots there is a fine metal mesh that prevents debris from entering the station body. In the previous version, the fabric glued along the inner grid of the speaker slots protected against the ingress of small debris and dust. It's difficult to say which solution is better. On the one hand, the fabric better protects from dust, on the other hand, if it peels off from the body, the fabric can rattle and cause sound distortion in the operation of the speaker.

The shape of the case is made taking into account ergonomic requirements. The station fits comfortably in the hand, its slightly widened upper part and the relief on the sides of the lower part prevent the radio from slipping out of the operator’s hand. The weight of the station with a belt clip and antenna is 203 g. The previous model with the same configuration weighed a little lighter - 191 grams. Nevertheless, the mass of the radio station is within the limits typical for most modern portable transceivers.

The belt holder is attached to the back of the battery using two screws included in the kit. In the old version, the clip was latched using a slide

Antenna

The antenna is quite flexible, has a smooth surface and a rounded top, which will have a positive effect on ease of use and ease of removing the radio station from under clothing. Compared to the previous version, the antenna of the AjetRays radio station is 2 cm shorter and has a length of 11 cm. The antenna connector is SMA “female” (the old version had a “male”). Thus, antennas from older versions are incompatible with the new model. When ordering mobile or stationary antennas, this feature should be taken into account.

Controls

The AjetRays AJ-446 v2 radio station has a classic “right-handed” control knob arrangement. The antenna is located on the left, and the handles are on the right. In this configuration, it is convenient to hold the radio station in your left hand, and switch modes with your right.

On the top panel there is a 16-position channel switch, a power knob/volume control and a three-color mode indicator. The font of the channel numbers is larger and more legible than the previous version. The channel switch knob does not have a raised position mark, like the previous version, but only. But the handles themselves are a little larger and more comfortable. As in the first version, channel numbers are announced in English when switching. In general, the switches do not cause any difficulties in using.

On the right side of the Ajetrays AJ-446 station body there is a connector for connecting a headset or remote 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 Phillips screwdriver.

On the left side there is a PTT button and two additional buttons, the functions of which depend on the programming of the radio station. The PTT button has a raised pattern and is comfortable to use with both the right hand (index finger) and the left (thumb). By default, the bottom function button turns on the “monitor” mode (turns off the noise suppressor), and the top button turns on the “Alarm” mode. In the previous version there was a single functional button responsible for the “Monitor” mode.

Function buttons and PTT are also used to program radio operating modes. So, for example, having set the 16th channel, turning on the walkie-talkie with the PTT button pressed switches the output power of the radio station's transmitter, the lower function button turns on channel scanning, and the top one switches the language of the channel number (English/Chinese/silent). Those interested can learn to count 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 in the previous version. As in the older version, the battery has a sled at the bottom for charging in a glass separate from the radio. By the way, when charging together with the radio station, fixation in the charging glass occurs due to the same battery slides, and a gap is formed between the front wall of the station and the glass. Probably, the enlarged charger socket was made with the expectation of using batteries of increased capacity and, accordingly, increased size.

The batteries have different fastening locks and are not interchangeable. In the new version of the AJ-446 station, the battery is inserted into grooves in the lower part of the radio body and snaps onto one latch on top. In the previous version, the battery in the upper part of the radio body was fastened with two latches on the sides of the battery, to remove which it was necessary to press two latches simultaneously. 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 AjetRays AJ-446 is not inferior to the previous version. Good speech intelligibility is ensured by high sound quality, despite the lack of a built-in digital voice processing function (compader). 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, the new station has twice as much power. The declared power of the AJ-446 is 4 W. The power of the sample tested by the MobilRadio laboratory turned out to be 5 W. This will undoubtedly have a positive effect on the communication range.

The radio station has the ability to switch output power (Low/High), which will allow you to use the station in maximum range mode or in battery saving mode. Different channels can be programmed with different power levels.

Programmable Features

The Adgetreiz AJ-446 walkie-talkie has a wide range of functions programmable from a computer:

• 50 CTCSS/107 DCS coding tones
• channel scanning
• priority scanning
• Transmit Limit Timer (TOT)
• busy channel blocking
• battery saving mode
• "repeater" frequency shift for communication via LPD/PMR repeater

Conclusion

In conclusion, I would like to note that the new version of the Agetreyz AJ-446 station is in the same price category as the Optim WT-555, Vector VT-44 Master stations. With a solid feature set, superior communications performance and a clean, utilitarian design, Ajetrays is an excellent choice for industrial and residential applications. The station is perfect for security guards, warehouse workers, supermarket workers, homeowners associations, builders, athletes, tourists, hunters and fishermen.

We present to your attention the new ergonomic radio Ajetrays AJ 446. Like the older model portable radio AjetRays AJ-344, the Ajetrays AJ-446 station is certified in Russia. The mere fact of having a certificate does not guarantee the quality of the product, but it does indicate the seriousness of the supplier and concern for the consumer. The fact is that the presence of a certificate automatically eliminates many questions to 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

The AjetRays AJ-446 station has a classic, strict design and a minimal set of controls. The radio is based on a high-strength metal chassis, ensuring reliability and durability of the structure. The body is made of high-strength plastic, has a rough surface that is 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 to the inside of the speaker grille, which prevents debris and dust from entering the station body.

The AjetRays AJ-446 radio station is equipped with a Li-Ion battery with a capacity of 800 A/h. Together with the fast charger supplied, the battery provides sufficient continuous operation time during the shift.

On the top panel there are: a light indicator, an SMA-type antenna connector, a 16-position channel switch and a volume control/radio switch knob.

An interesting feature of this model is that the channel number is announced when the radio is turned on or when the channel is changed. A female voice says the channel number in English with a slight Chinese accent. Probably in the near future we will get a Russified version of the dubbing. At least the latest Soontone-518 models “speak” Russian. This feature can be disabled or selected in English by your dealer or distributor. If this feature is disabled, there will be no messages when you turn on the radio or rotate the channel selector.

The announcement of channel numbers seems to be more of a useful function than a marketing trick, since it is quite difficult to distinguish the small numbers printed under the channel number selector knob, and besides, only odd-numbered channels are marked. In the dark or in poor lighting, you can determine the channel number in the absence of this function only by the number of clicks of the selector, first turning it to the far left position and counting the channel number, starting from the second.

The belt clip has a spring-loaded design with sufficient spring stiffness for reliable fixation and a power reserve for comfortable use. The upper tongue of the clip is equipped with an eyelet for attaching the strap to the wrist. This design, in my opinion, is not entirely reliable, since the load is transferred from the strap to the clip, from the clip to the battery, and from the battery to the body of the station. However, the complete absence of play in the battery and clip, as well as the high quality of the plastic, allows us to consider this drawback to be insignificant.

Like the older model AjetRays AJ-344, the AjetRays AJ-446 radio is equipped with a flexible antenna 13 cm long. This antenna design, combined with a threaded antenna connector mounted directly on the metal chassis, provides this vital radio station with maximum reliability.

Functions and operating modes

The AjetRays AJ-446 radio station has a minimal set of controls, which corresponds to the professional purpose of the device rather than the amateur one. A fairly large set of functions can be programmed from a computer. Moreover, functions will be controlled by changing the channel or by a single function 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 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 remain in effect until the radio is powered off.

Monitor. After pressing the button and a confirmation sound signal, the Ajetrays AJ-446 radio station will switch to signal reception mode without programmed CTCSS or DCS codes. In other words, this is a function to disable the code squelch. To return to the mode of working with code subcarriers, you need to press the button again.

Monitor momentary. The function is similar to the previous one, but the code disabling mode is active only when the function button is held down.

Squelch off. Disable squelch. An ethereal noise will be heard when the function is activated. Used to receive very weak signals that are interrupted when the squelch is turned on. The transition to normal mode is carried out by pressing the function button again.

Squelch off momentary. The function is similar to the previous one. To listen to over-the-air noises, hold the button. This feature is programmed by default.

Scan. Scanning is a function of searching for a signal on all channels. During scanning, the radio checks for the presence of a signal on each channel and stops on the channel on which the signal is present. The radio remains on the busy channel until the signal is lost. To start scanning, press the function button. Scanning is performed by searching through channels, starting with the current channel in ascending order of channels. To stop scanning, press the button again.

Priority Scan. If the radio is programmed with a priority channel, the radio automatically switches to that channel when a signal appears on it, even if the current channel also has a wanted signal. The radio will remain on the priority channel until the signal is lost and after the signal is lost for the programmed delay time. The scan will then resume.

Scan+temporary delete. “Temporarily exclude a channel from scanning”, that is, the ability to temporarily remove a channel from scanning. When scanning is stopped on a channel, the channel can be removed from scanning by pressing the function button. To return a channel to the scan list, you simply need to exit scan mode, or turn the radio off and then on.
Priority channel cannot be removed from scan.

TOT. The transmission time limit timer is designed to prevent one user from occupying the channel for too long. If you transmit continuously for more than the set time, the radio will stop transmitting and a beep will sound. To silence the beep, release the PTT button. You can then resume transmission by pressing the PTT button again. The TOT function is programmed using a PC.

Busy channel blocking. This function is programmed from a computer. If the selected channel does not have CTCSS or DCS tones programmed, 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 signaling. A CTCSS or DCS tone is a tone that allows signals encoded with a different tone or without a tone to be heard. This is necessary when several groups of users work on the same channel. If a channel is set to tone squelch, the radio will only receive a signal that contains the corresponding tone.

Likewise, the transmitted signal will only be heard by those channel users whose receiving tone matches the transmit tone of your radio station. If the receive tone is not set, you will hear all signals, regardless of whether they are tone-encoded or transmitted without tone.

Battery saving mode. The battery saving function reduces current consumption in standby mode (when there is no reception, transmission or button presses). The radio automatically switches to low current consumption mode 10 seconds after you stop receiving or the last time you press any button.

Cloning via cable. The radio allows you to copy all programmed functions of another radio using a cloning cable (not included).

The VOX mode stated in the instructions is not implemented in this modification. Perhaps this feature will be present in future versions.

What's inside?

The AjetRays AJ 446 radio station is a well-assembled device, based on a durable aluminum alloy chassis. The installation and soldering of the elements were also done quite well.

The housing parts are tightly fitted to each other, which provides satisfactory dust and splash protection. The radio 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 ensure complete moisture insulation in radio stations of this class. However, some models are provided with a hermetically sealed connection of the housing halves using a rubber seal, and have holes in the housing for controls and speakers. 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), transmitter power - 3.5 W. 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.

Vector slightly outperforms AjetRays AJ-446 in price, but loses in power and communication range and a little in functionality.

The Optim WT-555 radio is also slightly cheaper and has the same functionality as the AjetRays, which can be controlled using the existing buttons and display. The Optim WT-555 station has a b O higher power (4 W) and also b O higher 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, warehouse workers, supermarket workers, homeowners associations, builders, athletes, tourists, hunters and fishermen.

Portable walkie-talkie Agetreyz AJ 446
comparative review of the remake AJ-446 v2

In general, the switches do not cause any difficulties in using.

On the right side of the Agetreyz radio body 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 Phillips screwdriver.

On the left side there is a PTT button and two additional buttons, the functions of which depend on the programming of the radio station.

By the way, when charging together with the radio station, fixation in the charging glass occurs due to the same battery slides, and a gap is formed between the front wall of the station and the glass. Probably, the enlarged charger socket was made with the expectation of using batteries of increased capacity and, accordingly, increased size.

With a standard battery, the AjetRays radio can be placed in the charger in two ways - closer to the rear wall (charge mode) and closer to the front wall (no 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 close proximity to the charger (at the base) every now and then after a communication session return the transceiver to the charging cup. In this mode, a “memory” effect occurs when the battery is not completely discharged, but no longer carries the load. Despite the fact that the memory effect of Li-Ion batteries is insignificant compared to metal hydride and nickel-magnesium batteries, nevertheless, it should not be neglected. And the “life” of the battery does not increase with constant charging.

The batteries have different fastening locks and are not interchangeable. In the new version of Ajetrays, the battery is inserted into slots in the bottom of the radio body and snaps into place on top with one latch. In the previous version, the battery in the upper part of the radio body was fastened with two latches on the sides of the battery, to remove which it was necessary to press two latches simultaneously.
