Tait Communications TM9900 Multiband Multiprotocol Mobile Radio

The real experience of using Quansheng Taiko Kong TK11: suitable for advanced notes, with extremely strong signal, but the magic sound may be controversial?

Lucky to get the opportunity to try out the Quansheng “Taiko Kong ” TK11 walkie-talkie. After nearly two months of intensive use, today I would like to share my trial experience with you, hoping to give some reference to friends who want to buy it.

1. Unboxing and appearance design

The packaging design of TK11 is simple and elegant. After opening it, the host, dual antennas (one long and one short), Type-C charging cable, and charger are all available. The body is made of black matte material, with a solid grip, clear button layout, and moderate knob damping, which is easy to operate even with gloves.

2. Core Function Experience

1) Dual reception and dual transmission: “double insurance” in complex environments

I was impressed by the dual-guard function of the main and secondary channels of TK11. During an outdoor hiking activity, I used the main channel to communicate with my teammates, and the secondary channel to monitor the so-called outdoor “public” frequency. The two transmission keys are designed independently, and there is almost no delay when switching, which effectively avoids signal cross interference.

2) Ultra-wide frequency range: full coverage of amateur bands

As a full-band model, the TK11’s receiving range covers 0.5-1160MHz, and the transmitting bands include 50-54MHz (6-meter band), 136-174MHz (VHF), 350-490MHz (UHF), etc., far exceeding ordinary amateur models. I tested the communication effect of the 2-meter band and the 70-centimeter band. The voice was clear and the noise floor was well controlled. The shortwave mode may have higher requirements for the communication environment and has not successfully received the signal.

3) High power output: worry-free long-distance communication

The maximum transmission power of TK11 can reach 10 watts. With a high-gain antenna, compared with the 5-watt model I have, TK11 has obvious advantages in penetration and anti-interference. However, it should be noted that high power consumption is faster, so it is recommended to use a backup power supply.

4) Practical functions: spectrum analyzer and NOAA weather warning

The built-in spectrum analyzer function is very useful for frequency scanning, which can quickly identify the surrounding signal strength and avoid frequency collision. NOAA weather warning supports SAME decoding, which is crucial for outdoor activity safety. In addition, the 999 channel storage and cross-segment transfer functions also greatly improve the convenience of operation.

3. Battery life and portability

The 2500mAh lithium battery has a decent battery life and needs to be charged after about 8 hours of continuous use, but it supports Type-C direct charging and dock charging, which is flexible. The body weight is about 500 grams, which is slightly heavier than ordinary handheld devices, but considering its comprehensive functions, its portability is acceptable.

4. Controversial function: Discussion on the compliance of “Magic Voice”

The “Magic Voice” function of TK11 allows voice-changing calls, which is very interesting, but it also caused my concerns. According to Article 35 of the “Regulations on the Management of Amateur Radio Stations”, amateur radio station communications should use plain language or recognized abbreviations, and signals unrelated to amateur business should not be transmitted.

Problem analysis:

1. Compliance risk: The magic voice function changes the original voice, which may make the communication content difficult to identify, violating the “plain language communication” requirements. For example, if voice changing is used in emergency communications, it may mislead the recipient and even cause operational disputes.
2. Actual scenario restrictions: Even if used in daily entertainment, care should be taken to avoid interfering with other legal communications. Regulations clearly prohibit the sending of “signals unrelated to amateur business”. If voice-changing calls exceed the scope of technical exchanges, they may touch the red line.

Suggested improvement direction:

Manufacturers can consider adding a “magic sound function disable mode” in the firmware, or limit its use in the amateur band through software upgrades to ensure compliance.

5. Summary and purchase recommendations

Summary of advantages:
1) Full-band coverage + dual-guard function, suitable for advanced enthusiasts;
2) High power output and dual antenna design, excellent signal stability;
3) Professional functions such as spectrum analyzer and NOAA are highly practical;
4) Customized interface and user-friendly operation experience add points.

Disadvantages:

1. The Magic Sound function has legal disputes and needs to be used with caution;
2. The heat is more obvious at high power;
3. The body weight is slightly large, and it is easy to get tired when holding it for a long time.

Notes:

1. Be sure to apply for an amateur radio license before use to ensure that the frequency and power of the equipment are within the scope of the license;
2. Avoid transmitting in non-amateur frequency bands to avoid interfering with other services;
3. Use entertainment functions such as magic sound with caution and strictly abide by the plain language communication regulations.
   Quansheng TK11 is undoubtedly a powerful “all-round” walkie-talkie that can not only satisfy the fun of technical exploration, but also perform well in emergency scenarios. But as amateur radio enthusiasts, we must keep in mind the principle of “legality and compliance”. While enjoying the convenience of technology, we must jointly maintain the order of airwaves. We hope that manufacturers can find a better balance between functional innovation and regulatory compliance!

Anytone AT-588UV， All feeders, microphones, wires, and panel brackets are ready for loading onto the vehicle.

The body of the Anytone AT-588UV is installed on a steel plate under the driver’s seat, in the same position as most people. Before installation, use sandpaper to polish off the rust on the surface of the steel plate, and apply strong double-sided tape (also known as nano double-sided tape) to the back of the car body.

The next step is to install the separation line from the car body to the panel. If there are idle network cables and tools at home, there is no need to buy a finished panel separation line. Moreover, there is an advantage to making it yourself, which is to cut as much as needed and reserve some redundancy.

Once the wiring is done, it’s time to dismantle the car. If you want to install it , it’s best to prepare some clips from the car to prevent them from being damaged after dismantling. Just buy a set of clips for the corresponding car model, which come with various types of clips

The panel separation line passes through the buckle plate on the lower left side of the cab from the base of the B-pillar, and then goes up to the A-pillar through the buckle plate on the left side of the cab. At the beginning, the dashboard panel was glued to the upper left corner of the front windshield, and redundant extension cords and microphone extension cords were hidden inside the fiberboard on the roof. However, after being installed and tested on the road, it was found that the panel installed in the upper left corner of the front windshield may cover the driver’s face on the road, which may result in wearing a hat that affects driving and cause violations. On the other hand, it is not very convenient to view panel information or operate the panel.

Later on, a new adjustment was made, and the panel was glued to the left front of the driver’s cab with nano double-sided tape. The panel separation line and the microphone separation line could be connected to the panel from under the A-pillar. However, due to the use of a round diameter for the network cable, there was a small gap at the connection between the A-pillar and the driver’s cab, which was not perfect.

Next, let’s talk about the hand microphone separation line.

Used to having a hand microphone in right hand, but the dashboard panel is installed on my left hand, which is why there is a hand microphone separation line. The original car did not have a starting function, but a space was reserved and covered with a cover plate. After measuring the cover plate with a ruler, it was found that a network cable adapter could be installed. Connecting a network cable from the car console’s hand microphone socket would be a hand microphone extension cable, which is perfect and does not affect the use of right-handed hand microphones.

All of the above are actually relatively simple, the most difficult one is actually connecting the power cord. Since I am using the car starter battery for direct power supply, I need to guide the wires from the engine compartment into the driver’s cabin. But after searching the engine compartment, there was only one bus harness, and it was located in the middle of the driver and passenger seats.

There was really no other choice but to grit my teeth and try to find a solution from the bus harness. Fortunately, I reached for the bus harness from the driver’s cab and found that there was still a lot of space inside the rubber tube. That’s why I had the courage to use a small Phillips screwdriver to poke a hole in the rubber tube of the bus harness from the engine direction towards the driver’s cab direction. To reduce trouble in the later stage, I used a 1.5 square meter dual core silicone wire and treated the dual core as a single core.

The space for the bus harness in the driver’s cabin is very narrow, and all kinds of metal parts of the vehicle are exposed with handles and arms hanging out. Despite the effort, the person with the heart finally introduced the power supply into the driver’s cabin. The power cord still passes through the buckle plate on the lower left side of the driver’s cabin to the bottom of the B-pillar, and can be connected using a plug-in terminal. Before connecting the power cord to the car radio, try to use a multimeter to measure whether the positive and negative terminals of the power cord are consistent to avoid damaging the equipment.

After the power supply of the car radio is solved, only the antenna feeder system remains. As I am using a suction cup antenna, I enter the car from the B-pillar through the rubber strip of the door and reach the bottom of the B-pillar. The advantage of doing this is that it can shorten the length of the feeder as much as possible, and avoid drilling or vehicle breakage as much as possible. The disadvantage is that some of the feeder lines may be exposed and the rubber strip of the car door may protrude.

Traditional frequency writing usually requires the use of a computer and specialized software, as well as a frequency cable (such as a USB to K-head interface cable) to achieve. This method requires users to have certain computer operation skills and walkie talkie frequency writing knowledge. The operation process is relatively complex, and there may be a certain learning threshold for non professionals.

Due to the complexity of operation and dependence on external devices, traditional frequency writing methods often require a long time to prepare and implement. Especially in the scenario of large-scale deployment of walkie talkies, each walkie talkie needs to perform frequency writing operation one by one, which will greatly increase the time cost.

The emergence of Aerial frequency writing technology has effectively solved this problem.

Air frequency writing technology, as the name suggests, refers to the technology of remotely setting and adjusting the frequency, channel, and other parameters of walkie talkies through the air channel. This technology breaks the traditional limitation of writing frequencies through computers and programming cables, achieving wireless and remote parameter settings for walkie talkies.

Specifically, the Aerial frequency writing technology utilizes wireless communication technology to send the parameter setting instructions of the walkie talkie in the form of wireless signals to the walkie talkie. After receiving the instructions, the walkie talkie automatically adjusts its operating frequency, channel and other parameters according to the instructions. This process does not require connecting a computer or programming cable, greatly simplifying the operation process and improving work efficiency.

Aerial frequency writing technology has been widely used in various fields, such as public security, fire protection, medical and other public safety departments, which extensively use walkie talkies for communication and coordination. Aerial frequency writing technology can facilitate centralized management and parameter adjustment of these walkie talkies.

The security of data is an important issue in the wireless transmission process of Aerial frequency writing. If the data encryption and authentication measures during the process of writing frequency in the air are insufficient, it may lead to illegal interception or tampering of data, thereby causing security risks. The air interface frequency writing technology usually adopts security measures such as encryption and authentication to protect the security and privacy of data transmission process. This helps prevent data from being illegally tampered with or sensitive information from being leaked.

The over the air frequency writing technology is gradually becoming the mainstream technology in the field of walkie talkie frequency writing due to its advantages of convenient operation, high efficiency, safety, and wide applicability. The application of this technology will further improve the efficiency and communication quality of walkie talkies, bringing users a more convenient and reliable communication experience.
