PROGRAMMING FUNCTION 1. Channel operating frequency VRATVARK package for channel programming - The dealer can use software catching and setting the transmitting and receiving frequencies. 2. Digital Codes and CTCSS The Dealer or Manufacturer may use the VRATVARK software package to program the DCS and CTCSS systems. 38
39 When DCS or CTCSS is configured on a channel, the transceiver can receive on the same channel and with the same DCS and CTCSS system - you can only turn off the noise reduction circuit in this channel. In addition, the other transceiver must be using the same frequency with the same DCS or CTCSS - in this case, it can only receive your transceiver's signal. If the same frequency is used, but a different DCS or CTCSS system is used, then it is impossible to disable the noise reduction system - the yellow indicator will light up. 3. Setting the squelch level The dealer or Manufacturer can use the VRATVARK software package to program the squelch system within the Battery Energy Saving levels If the transceiver has the Battery Saving function activated, the symbol S will appear on the display. The transceiver will enter the Power Saving mode after 10 seconds. termination of transmission. 5. Disabling the alert tone When the tone function is activated, the clock symbol is displayed on the display; when deactivated, it is disabled - when the transmitter is turned on, there will be no tone signal. 39
40 6. Output Power Selection You can select the transmit signal power for each channel. When high power is selected, the display shows HI, when low power is selected, LO is displayed (the factory default is LOW). 7. Scan mode and parameters A) In scan mode, the transceiver scans each channel, and when a signal is detected reception, scanning is paused and the transceiver waits until the signal on that channel disappears. The dealer can set the delay time. If the receive signal reappears while waiting, the transceiver will continue to hold the channel within the delay time until the signal disappears, after which the transceiver will return to scan mode. The factory default delay is set to 3 seconds. B) Start Scan Press (Scan) for 2 seconds to start scanning. Scanning starts from the current channel and continues channel by channel at an increasing pace. At the same time, the yellow indicator flashes. 40
41 When a receive signal appears on the channel and the command matches, the yellow indicator will remain lit and the squelch will turn off. Press (Scan) to exit the scanning state. C) Priority Scan The Dealer or Manufacturer can use a software package to set 21 types of Priority Scan: a) Set a fixed channel as the Priority Scan channel. Note: The channel cannot be empty. b) Set the selected channel as the priority scan channel (the current working channel is the priority scan channel). If you have already set a Priority Scan channel but are unable to receive the corresponding signal during scanning, the transceiver will return to the Priority Scan channel scan mode as it scans each channel. c) When the current channel is set as a priority scan channel, the PRI icon appears on the display. D) Return to channel 41
42 During scanning, press the (PTT) button, the transceiver can transmit in the following 4 modes: a) Select mode: During scanning, the transceiver will transmit from the main channel (working channel is set as the main channel). b) Select + Transmit Mode: During scanning, when any matching signal is received on that channel, scanning will stop for a short time and transmission will start on that channel. Otherwise, the transceiver will transmit on the main frequency. c) Priority Mode: During transmission, the transceiver will transmit on the main channel previously programmed. d) Priority Mode + Transmit: During scanning, when any corresponding signal is received on that channel, scanning will stop for a short time and transmission will begin on that channel. Otherwise, the transceiver will transmit on the priority frequency. Upon completion of transmission, the transceiver will return to scan mode for the delay time programmed by the dealer or Manufacturer. 42
43 MAINTENANCE The ARGUT A-24 transceiver you purchased belongs to the family of precision electronic devices and therefore requires careful handling. The following maintenance recommendations may extend the life of the transceiver. 1. Do not attempt to disassemble the transceiver, as unprofessional disassembly may cause damage to the device. 2. Do not use or charge the transceiver in an explosive environment (the air contains a lot of very fine sand, dust and places with a lot of chemicals). 3. Turn off the power to the transceiver at gas stations. 4. Do not place the transceiver in direct sunlight or in hot places for a long time, as high temperatures will shorten the life of electronic parts and deform plastic parts. 5. Keep the transceiver dry as rain and moisture will corrode electronic circuits. 6. To ensure stable power supply, use a special USB cable connected to the DC jack of the transceiver. 43
44 7. If you experience any unusual transceiver conditions, unusual odor, or smog, immediately turn off the power to the transceiver and separate the battery. TROUBLESHOOTING Problem No response when power is applied Cannot talk to members of the same group Solution The battery pack may be low. Recharge or replace the battery. The battery pack may not be installed correctly. Check its installation and reinstall the unit again. Make sure you are using the same frequency and CTCSS/DCS as other members of the same group. Other members of your group may be too far away from you, so make sure you are within coverage of other transceivers in the group. Communication range is short Make sure the antenna is properly connected and secured. Make sure you are using the original antenna. 44
45 Voices of members of other groups can be heard on the channel Battery life after charging is too short Callers' voice reception is not loud enough or intermittent Water has entered the transceiver The dealer and user may have set the squelch level too high. Reduce the noise reduction level. Change the frequency. Change your CTCSS/DCS number. This changes the signal of all transceivers in your group. The battery pack is exhausted and can no longer be used. Replace the battery pack with a new one. Make sure the battery pack is fully charged. Make sure that the transceiver's microphone is not blocked by foreign objects. If water gets into the transceiver, immediately remove the battery, drain the water, and place the transceiver in a dry, ventilated place. Be sure to send the transceiver to a service center. 45

NEPTUNE VHF FM RADIO R-300 User Manual 1. WARNING. It is prohibited to work on transmission without obtaining permission. Turn off the radio while refueling or while standing on
A cell phone is not always convenient, it doesn’t always work. Satellite phone - yes, in some cases this is the only connection with the “mainland”.
Now about everyday realities. Let's look at radio stations. When everyone has the same stations, there are usually no problems, everyone can hear each other. And when the stations are different, how to “make friends” between them. After all, not all people engaged in the same type of activity have the same radio stations. There can be many situations that require rebuilding different stations:
Are you skiing and want to build a walkie-talkie with a guide?
You are traveling in several cars on vacation, with a large group.
You communicate in the mountains with other groups of climbers.
If you are in trouble, ask for help.
Interact with other groups during rescue operations, etc.
Let's first look at what types of radio stations there are. From simple to complex. “Soap boxes” “Soap dishes” - “soap boxes are different”. They are divided by transmitter power and frequency. You've probably noticed that walkie-talkies have different numbers of channels: 69 channels, 22 channels, 8 channels, with a different number of “subchannels”.
When engaging in active sports and recreation, it is very foolish to assume that you, your comrades or other people around you will not need some outside help in your sport. Therefore, being able to ask for help in a timely manner can be very important. Remember, there are no subchannels.
For the most part, you use this terrible word to refer to the tone CTCSS or digital DCS noise suppressor. What it is, see the appendix at the end of the article. There are also different markings: on boxes, walkie-talkies, or under batteries: LPD, PMR, FRS/GMRS.
Let's figure out what's what. FRS/GMRS is an American standard for household transmitting devices operating at frequencies that are not permitted for use by the common man in Russia. You cannot use these radios legally.
PMR (“Personal Mobile Radio”), 8 channels are allocated for walkie-talkies with a transmitter output power of no more than 0.5 W. The European standard for household transmitting devices (446.00625446.09375 MHz) due to the 6.25 kHz grid step, they are not compatible with almost anyone other than the same PMR standard radios. On amateur radio stations where there is no 6.25 kHz step, you can tune by slightly deviating from the given frequency.
Registration of radio stations is not required. LPD (Low Power Device) can be used freely - registration of radio stations is not required. They operate in the range 433.075-434.775 MHz. The most successful household radio stations for active pastime, especially if you bought the “right” models, which can be tuned to a little more power (up to 3W), compared to the allowed 0.01W. There are models with a screw-on antenna. You can replace it with a longer antenna from a professional or amateur radio station, which will greatly improve its transmitting and receiving characteristics.
P.S. The use of LPD (SRD) radios is not permitted in the following countries: Belgium, Denmark, Finland, Ireland, Luxembourg, Portugal, UK, Spain, Lithuania, Latvia, Estonia, Croatia, Turkey. There are no such restrictions for PMR radios; you can safely travel abroad and use them freely.
As for FRS/GMRS, this range is prohibited primarily in Russia. Amateur radio stations Good communication does not come cheap. With these words I want to start the story about mid-level equipment. Chinese KENWOOD TK-K2AT, TH-K2AT and TK-150S range 137-174 MHz, or TK-K4AT, TH-K4AT and TK-450S range 420-470 MHz work with any LPD/FRS/GMRS point-and-shoot cameras. These and other similar devices are sold quite widely in our country.
BUT! If you only knew how much I myself dislike such “buts”. Walkie-talkies in this price range, with the stated characteristics, are a pig in a poke from my experience. Reliability, reliability, durability, maintainability. It’s precisely the reliability in these Chinese Kenwoods that is lame. How quickly it will stop working is unknown.
This “lucky or unlucky” class equipment has been tested from our own experience. Kenwood is a good manufacturer of professional equipment at reasonable prices. If your China Kenvod breaks down, remember Kenwood has nothing to do with it, it has never even seen these stations.
There are so-called “two-bend” radio stations that combine the ranges that interest us, the so-called two-meter range and the 70cm range; they are named so for a reason - this is a display of the wavelength in the name. These are frequencies 137-174 MHz and 420-470 MHz, the second, as you remember, includes household radios “soap boxes”.
Why do you think the 2-meter range is interesting? And in fact, very many. The first and very important argument: rescuers from the Ministry of Emergency Situations work on it. Secondly, a huge “army” of radio amateurs communicates in this range. Third, it has good coverage in mountainous and wooded areas; the 70cm range only wins in dense urban areas. When engaging in active sports and recreation, it is very foolish to assume that you, your comrades or other people around you will not need some outside help in your sport.
You can’t rely on a mobile phone everywhere, and you’ve experienced this yourself. Therefore, being able to ask for help in a timely manner can be very important. Taking this into account, we can conclude that having a 2-meter range in your walkie-talkie will not be superfluous. Radio stations at this level require registration if you are going to use them legally.
There is nothing complicated about this, but more on that later. Argut Argut is a well-known brand among radio amateurs and is synonymous with high-quality amateur radio stations. Argut A-41 - a good combination of price and quality simply forces us to dwell in more detail on the models of this manufacturer. Here are three models of portable stations that are worth paying special attention to - Argut A-23, Argut A-53, Argut A-41. Briefly about the advantages and disadvantages.
They are all very similar in their characteristics. ARGUT A-53 Pros: Full 5W transmitter power; price; ability to use: lithium, metal hydride and nickel-cadmium brand batteries. The transceiver is made of shockproof plastic.
Minus: a bit large and heavy compared to the other two. The headset connector is not very well thought out, so it doesn’t fly out, you have to press it with a rubber band. ARGUT A-23 Pros: Very compact and light - 200g. Dustproof and moistureproof. Ability to use: lithium, metal hydride and nickel-cadmium brand batteries, as well as AAA batteries.
I myself use such a walkie-talkie at various events, which sometimes take place in the forests and underground. The A-23 has proven itself to be very good. Cons: Weak transmitter, no more than 3W. ARGUT A-41 Pros: Full 5W transmitter power, compact. The transceiver is made of shockproof plastic and has a degree of protection IP-65, which allows the A-41 to be used in extreme conditions. Thanks to such changes, the transceiver has excellent technical characteristics and will satisfy the needs of the most demanding buyer.
The A-41 stands apart; it can be described as “reliable.” This walkie-talkie fits the semi-professional category. This walkie-talkie has only a two-band range, but its merits are not in a wide reception range, but in reliability.
RADIO OPTIONS
The antenna is the best amplifier. Whatever “cool walkie-talkie” you have with a bad antenna, it doesn’t matter. All antennas that come with radio stations have very weak characteristics due to their broadband. Headsets or the same handsfree are very convenient, they free your hands from the radio station, but you can also quickly receive the information transmitted to you.
Push-to-talk is a remote unit on a wire that connects to your walkie-talkie, with a microphone, speaker and transmit button. Also, in most cases, it has a headphone jack. A very convenient thing, regardless of the type of station. The walkie-talkie can be in an internal pocket (for example, to keep it warm) or in a backpack, and the push-to-talk button is brought to a convenient place and connected to the station with a twisted wire. There are different types of batteries: lithium, metal hydride and nickel-cadmium. Briefly about the pros and cons when used in radio stations.
Lithium - have the largest capacity, with a modest battery size. Accordingly, long-lasting energy output. Their downside is that they are very afraid of negative temperatures and quickly lose tension and the ability to continue working. LPD range application. The channels are located at frequencies 433.075 MHz to 434.775 MHz in 25 kHz steps - a total of 69 channels. PMR band (Private Mobile Radio, pi-er) is a European license-free system. Briefly about CTCSS. The tone coding function is necessary to divide correspondents (users) into groups working on the same radio channel. Only those correspondents who have the same CTCSS code (tone) can listen and transmit within “their” group.
For those who are not tuned to the required CTCSS code, these transmissions will be suppressed (as unnecessary noise) and nothing will be heard. At stations where the tone squelch is disabled, all participants on the air will be heard. Briefly about DCS (Digital Coded Squelch) is a digital infrasound selective calling system. To simplify greatly, everything is the same as with CTCSS.
They say that great masters copy, and geniuses steal. A similar picture can be observed in the portable radio market. The total dominance of the Russian market by various Chinesewoods and Baofengs, which, in general, work well for their money, relegates manufacturers of other worthy equipment to the background. And in this review I want to tell you about just such a radio station - ARGUT A-54.
Don’t think that I’m immediately starting to praise this radio station without even really talking about it, but as always, the first impression was purely positive. Yes, ARGUT also makes its radio stations in China, which, as you know, is inhabited exclusively by great masters who have perfectly mastered the skills of copying, cloning and borrowing. Moreover, sometimes it turns out very successfully. By the way, for the Chinese, given their mentality, making a copy of something good is not something shameful and in their understanding it is not a fake. For them, it is more about imitating the great masters. But this is all lyrics, and now let's take a closer look at the hero of today's review.
Appearance
According to tradition, let's start, of course, with the appearance. The radio station is supplied in a cardboard box with fairly high-quality printing.
The box also contains pictures indicating the expected scope of application of the radio station, mountains, fishing, hunting, construction and even the military sphere. Is it really? Let's check.
The box contains the radio station itself, a battery, an antenna, a clip, a charger, a power supply for it, a lanyard and instructions.
Radio station
Argut A-54 is made in a classic design. Many elements of the case design are borrowed from their older brothers from Japan, namely Vertex Standart VX-820 and Icom IC-V80. And, in my opinion, this is correct, since the radio only benefited from this.
The display divides the station body into two parts. The display is quite contrasty and is not hard to read from the sides and bottom, but it’s a little hard to read from above.
In the dark, the display and keyboard are illuminated with a pleasant amber light.
The speaker and microphone are located on top. In general, the upper part of the front panel is reminiscent of another Icom IC-V80 station.
At the bottom there is a keyboard necessary both for direct input of a frequency or a pre-programmed channel, but also for quick access to subtones, which, in my opinion, is quite convenient. Stylistically it is also very reminiscent of Icom.
The keyboard buttons are made of rubber and are pressed with a pleasant, informative click.
On top there are control knobs, an emergency call button and a connector for connecting the SMA-Female antenna. The design of the upper controls almost completely copies those of the Vertex Standart VX-820.
On the left are the transmission exit buttons and two programmable keys. The design of the keys is taken from the vertex.
On the right, under the plastic plug there is a jack for connecting a headset or programming a radio station. There is a sealing rubber gasket around the perimeter of the plug. Very good. As you might guess, this element is also borrowed from the VX-820.
The radio chassis is made of cast aluminum. The casting quality can be described as average. It can be worse, but overall it’s normal.
Here, under the battery, there is the serial number of the radio station and a marking plate on which it is written “LICENSE-FREE RADIO STATION ARGUT A-54” and the supply voltage is indicated.
The myth that says that we have an unlicensed radio station in front of us is very convenient to poke under the noses of presumptuous law enforcement officers. Unfortunately, or maybe fortunately, I did not have the opportunity to check this point, but, nevertheless, this sticker will warm the soul of those who are very worried about the legality of using the radio station.
The battery connection unit is made using spring-loaded contacts and is protected around the perimeter by a sealing gasket. Very good.
Battery
Lithium-ion. Voltage 7.4 volts and capacity 2300 mAh.
The battery weighs 122 grams. For comparison, the Quansheng TG-UV2 battery with a slightly smaller capacity weighs only 85 grams. By the way, the assembled radio station weighs quite a lot, with battery, clip, and lanyard, as much as 327 grams.
Let's check whether the capacity matches the declared one. For testing, the battery was charged with the original charger until the green light came on. After that, it was discharged using a universal charger/discharge device iCharger 106B+ with a current of 400 mA (average current when the radio station is operating in transmit mode in maximum power mode in the receive / transmit ratio - 70 / 30).
As you can see, the battery capacity is 2550 mAh, which is more than the declared capacity! Usually the battery is one of the bottlenecks of any radio station made in China, but here everything is in perfect order. Just great!
Antenna
The Argut A-54 radio station is equipped with a conventional single-band, compact whip antenna. Let's measure its characteristics using the RigExpert AA-600 antenna analyzer.
As you can see, the minimum SWR occurs at a frequency of 432 MHz. The SWR=3 bandwidth is about 120 MHz, which is very decent.
This completely covers the operating range of the radio station, so the antenna is universal and configured correctly. It may not be the most efficient antenna, but it works.
Charger
The design of the charger is also partially borrowed from Vertex Standart. It is noteworthy that you can charge the radio and an additional battery at the same time.
Functions
The radio station has all the functions necessary for operation. There is no point in doing a full overview of the functionality; it is perfectly described in the instructions, but it’s worth going over the main points.
I liked the fact that the control of subtones is displayed on the keyboard; you can quickly configure subtones for both reception and transmission.
The station's menu is quite extensive, but not overloaded with unnecessary items.
In general, the controls are quite convenient, and if you have previously had radio stations made in China, you will quickly get used to it. Roughly speaking, for professional use it is enough to program several channels and use them; for amateur and civilian use, you can also program channels, or you can do everything manually, this is also possible, but it takes some time.
Software
Similar to any other Chinese programming software. All such programs are based on one template. Nothing particularly noteworthy. I did not have any problems programming the ARGUT A-54. That's a plus.
Inside
And the most interesting things await us inside. Anyone who thought that this was another baofeng, relax, ARGUT A-54 is a real full-fledged superheterodyne. But first things first.
I liked the build quality. It's the attention to detail. When I disassembled this radio station, I did not have the slightest feeling that the device was made in a hurry. Everything is quite well thought out and even the volume control and valcoder handles, in addition to the slots that prevent the handle from turning, are secured on top with screws and lock washers (see photo above).
When I disassembled this station, the first thing that caught my eye was the design of the nuts on the shafts of the volume control and tuning encoder.
I have never seen such a sealing system on any Chinese radio station. All nuts securing the adjustment knobs to the body have a groove for a rubber seal on the outer and inner surfaces, which creates a kind of gland that provides excellent sealing. This is a huge plus. 
And although the station is not protected from complete immersion in water, it can easily withstand direct splashes and rain. The speaker and microphone have been leaked with sealant.
The display is well glued into the case. And the keyboard, although not glued, is pressed well against the case by the board at several points, which also prevents moisture from penetrating inside the case.
There is a fairly thick rubber seal around the perimeter of the case, which also serves to prevent moisture from getting inside.
Board with keyboard and display.
The receiver is a superheterodyne with double frequency conversion.
ULF - Toshiba TA7368F
The VCO is hidden under the screen, which is good. Using fingerprints, you can probably identify the craftsman who assembled the radio station.
First intermediate frequency filters.
The WFM receiver is made on RDA5802N, well, the Chinese can’t help but shove it into the radio station and that’s it. In their opinion, security guards, tourists and other citizens absolutely cannot do without it.
Heat sink of the output stage transistor. If anyone doesn’t understand, a rectangular brass blank is soldered onto the board, providing thermal contact with the chassis through a silicone heat-conducting gasket. Interesting solution.
In general, the installation was well done, although with some minor flaws, but overall there is nothing particularly to complain about.
Testing
Let's check that all the parameters of the radio station correspond to the declared ones and even a little more. Below I will write the parameters measured as a result of testing, and not indicated in the instructions. The radio station is fully disclosed in frequency and power, so the data from the instructions will differ from the actual ones.
Since our radio is declared as license-free, we will conduct testing in the middle of the designated range, namely LPD (433.925 MHz) and PMR (446.045 MHz). To test and study the main parameters of the receiver and transmitter, the Rohde&Schwarz CMS 52 service monitor was used.
To measure current consumption, the radio station was powered from an Atten PPS3005S laboratory power supply, and measurements were carried out using a Vichy VC8145 stationary multimeter. Other auxiliary equipment was also used in the measurements.

Operating experience and results
I tested this radio for about two weeks and I can say that I liked it. Still, borrowing ideas from other famous manufacturers is the right step, take the best and make it affordable. I was very pleased with the sensitive receiver and fairly convenient controls. There were no problems with programming at all, which cannot be said. It was somewhat annoying that when you enter the menu, you find yourself not where you left off last time, but at the first item. I didn’t purposefully check the moisture protection, and somehow the ARGUT A-54 hasn’t been exposed to rain yet, but one disassembly was enough for me to understand that the moisture protection works.
Another point that is worth paying attention to is that in the photo the radio looks worse than in reality, and in my opinion, the image of the product is somewhat distorted. But as soon as you pick up the radio station, you immediately understand that this is not just another balalaika from heaven, but a completely serious thing. Of course, everyone’s idea of good equipment and its prices is different, but in my opinion, the ARGUT A-54 is worth the money, which, again, cannot be said about other brands. In any case, I was very pleased with the walkie-talkie, and I’m glad that this copy will remain with me for further use and study.
