  • Is Digital Radios HYT G36 worth unpacking?

    Once upon a time, the Hytera TD370 was my dream walkie talkie. Unfortunately, the price of this machine has always been very high. I believe that the price not only makes me, but also makes many HAM Radio Fans with limited budgets flinch. However, Hytera has not given up on the entry-level DMR digital analog integrated walkie talkie. Recently, it launched a Hytera G36 digital analog integrated walkie talkie. Of course, you can’t miss this affordable digital walkie talkie.

    Like the HYT TD370, this Hytera G36 digital analog integrated walkie talkie is a single U segment device with a maximum transmission power of about 3W. It can set two transmission powers, high power and low power. The battery capacity is 2200mAh. It supports Type-C port charging. At the same time, it also has a 0.9 inch OLED display screen, which can check the working status of the machine.

    At first glance, when I saw this walkie talkie, I felt it was still very compact. The front speakers of the machine accounted for a large proportion, and the actual measurement of the speaker’s external playback effect was very good. The sound was loud but not explosive, and the bass was thick and powerful.

    In addition to the main unit, there is also a back clip and hanging rope inside the packaging, which is easy to carry with you after installation. In addition, a charging cable is also included when purchasing, making it convenient to charge and write frequency to the machine. The advantage of this machine is that it is easy to write frequency, and you can set the frequency for the walkie talkie using your phone’s data cable, without the need to purchase a dedicated frequency writing cable.

    The radio approval code for this Hytera G36 is 2022FP18614. Everyone can verify the machine and apply for a radio license, and legally use radio equipment. The body adopts a one-piece design, and the battery is not detachable. However, the installation of the back clip is detachable and easy to disassemble. Unlike some walkie talkies, the difficulty of removing the back clip is extremely high, which is very wasteful.

    The overall feel of the Hytera G36 is still good, with a great one handed feel. The antenna is not detachable and has an integrated design, making it very easy to play with.

    The left side of the machine includes PTT emission buttons (Push To Talk), which increase and decrease the volume. The buttons have a crisp and sensitive feel, and the texture of large factory workmanship. There are also slots on the side, so it is not ruled out that there are seat charging accessories to choose from.

    On the right side of the machine is the interface of the earphone, which has a dust plug at the interface, which can provide waterproof and dustproof effects. However, unlike the TD370, which has an IP54 waterproof and dustproof level, Hytera G36 has not found a specific waterproof and dustproof level.

    The Type-C interface at the bottom can charge the walkie talkie or connect to the computer to perform frequency writing operations on the device and set the frequency parameters of the machine, which is very convenient. Moreover, Type-C data cables are now very popular, and ordinary mobile phone charging cables can charge the machine, making it more convenient for external use.

    The top of the machine has a channel knob and an orange TK button. The TK button can be customized through the intercom frequency writing software. In addition to the TK button, P1, P2, and volume up and down buttons can all be customized (volume up and down can only be customized by long pressing, because short pressing is volume up and down).

    The weight of the entire machine, combined with the back clip and lanyard, is only 158 grams. I believe that users who hold mobile phones weighing over 200 grams can understand how lightweight this weight is.

    In general, although the price of Hytera G36 is less than $100, its functions are no different from those of DMR digital analog integrated walkie talkie above $100. It can be seen as Hytera’s compensation for the digital analog integrated walkie talkie product line at this price. If you have a demand for DMR digital walkie talkie, have a DMR digital relay locally, or want to use digital walkie to connect MMDVM raspberry pie for global communication, Then this Hytera G36 is undoubtedly the first choice of the cost-effective DMR digital interphone product.

  • Two way Radio ID and application

    General units in the application of walkie talkies value instant response communication in walkie talkie communication. Pressing PTT to speak and receiving other walkie talkies with the same frequency within the signal coverage range of the transmitting walkie talkie achieve fast voice communication and meet efficient work needs. In the widespread application of walkie talkies in various industries, it is necessary to have high communication requirements targeting individuals and affiliated groups, reducing interference with other people and groups in the communication unit, and affecting work efficiency. This requires walkie talkies to have their own number and affiliated group number to achieve targeted communication needs.

    In fact, in the era of analog walkie talkies, various signaling methods (such as DTMF, 2TONE, 5TONE, etc.) can also be added to higher-level walkie talkies to meet the requirements of individual calls, group calls, and group calls between walkie talkies. However, the application in analog walkie talkies is relatively complex and the usage atmosphere is relatively low.

    Now that digital intercom applications have become mainstream in the market, do they all have the function of intercom ID? The answer is yes. Due to the scale sampling and coding application of digital technology, each digital walkie talkie is easier to configure with ID encoding function. In fact, each transmission includes its own ID code, which is easy for the receiving system to recognize, manage, and apply, providing basic conditions and guarantees for ID identification and digital cluster application of digital walkie talkies. This is also one of the advantages of digital walkie talkies.

    Digital Walkie Talkie ID

    The ID of a digital walkie talkie contains its own information in each transmission, so during the programming process, it is necessary to set the self ID and group information set in the application to which the walkie talkie belongs, so as to facilitate the display and management of relevant information on the receiving end. This is a problem that needs to be noted in digital walkie talkie programming. Before programming applications, we need to understand the specific application situation of the unit. Only by correctly setting the ID and group information can we achieve various subsequent management and applications.

    The above is the setting interface for the ICOM IC-F3108D/4108D digital walkie talkie from Japan. To achieve selective calling, setting the frequency alone is not feasible. It is necessary to set the Unit ID, individual calling, group calling list, mute form, and button settings for each machine to achieve the corresponding functions.

  • Best ICOM Shortwave Radio ?

    Which model of ICOM shortwave radio is the best to use ?This question is not very scientific, but it is often asked. In fact, it should be said that a radio station that meets the installation environment and performance requirements of users and has excellent cost-effectiveness is a good radio station. However, different models of radio stations may be more suitable for specific models of shortwave radio stations due to different usage environments and requirements. The suitable model is the best model.

    Communication performance of a device

    Short wave radio is a long-distance communication device that utilizes airborne ionospheric communication. Due to its relatively independent installation and long communication distance (over 200Km), it is more suitable for emergency communication and has been used today as a classic amplitude modulation communication method. The disadvantage is that the variation in thickness and density of the high-altitude ionosphere over time leads to unstable communication quality and uncertain usage frequency. It is more necessary to determine the working frequency, power, etc. based on the actual situation of local experiments, making this characteristic relatively high and unstable in actual communication, making it more suitable for emergency communication professionals and enthusiasts to conduct long-distance wireless communication.

    Common models of ICOM shortwave radio stations

    Marine shortwave radio stations have significantly improved waterproof performance compared to land radio stations, with operating frequencies generally set internationally, while amateur radio stations have an advantage in multifunctional and large screen displays. Users can flexibly choose the best cost-effective product based on their specific usage environment, performance (such as power size, frequency stability, ALE, paging and ACC output parameters), and display requirements. The following IC-F8101 and IC-F718 are more professional applications, IC-7000 is more amateur, and IC-7800 is high-end indoor applications.

    Common models of ICOM shortwave radio stations include professional shortwave radio stations IC-F8101, IC-F718, and IC-F7800; Amateur multifunctional IC-7000, IC-7300, IC-F7000, and marine shortwave radio IC-M710, IC-M710RT, IC-M801E, etc. They have the same external appearance except for the working frequency band and power, and their specific parameters are related to each other. You can choose a suitable shortwave communication product according to your actual needs.

  • Short wave Radio VFO A/ B

    Introduction to shortwave communication

    Short wave radio is a communication device operating at frequencies below 30MHz, which relies on ground waves and airborne ionospheric reflection to propagate communication signals, achieving long-distance short wave communication across regions and oceans. Short wave equipment is relatively simple and easy to install, but due to its low operating frequency, large antenna volume, and unstable ionospheric reflection in the air, it causes significant communication fading, instability, and unstable frequency selection, making it a traditional long-distance communication method. The following figure shows examples of common Japanese ICOM shortwave radio stations such as IC-F8101 integrated receiver and related shortwave radio stations.

    VFO operating mode of shortwave radio station

    VFO working mode is a working mode that many professional and amateur radio stations have. Its working frequency communication panel knob or button can be set at any time, making frequency setting convenient.

    Careful friends will find that in VFO mode, there are generally two frequency memories available for selection: VFO A and VFO B. For example, the professional radio station IC-F8101 of ICOM in Japan has two memories: VFO A and VFO B. After entering VFO mode, pressing the function key A/B can switch between VFO A and VFO B, as shown in the following figure.

    The default VFO working mode in the above figure is VFO A working frequency. Pressing the A/B multifunction key can switch between A and B keys. The figure on the right shows that when the receiving and transmitting frequencies are different, the receiving frequency of VFO A is 14.100MHz; The transmission frequency is stored in VFO B and the frequency is 14.105MHz.

    The role of VFO A and VFO B

    Obviously, when the transmission and reception frequencies are the same, both VFO A and VFO B frequencies can be selected for operation. But what should I do when the frequency of sending and receiving work is inconsistent? At this point, VFO B plays a role in storing the transmission frequency, and a single VFOA or VFO B cannot be achieved. This is the common SPLIT working mode of VFO.

    That is to say, VFO A and VFO B provide a solution for transmitting and receiving different frequencies through relay stations.
