In China, almost all sports use commercial walkie-talkies or amateur radios as the main machine, and there are few professional SPORT RADIO. Professional sports radios are usually more demanding than home unlicensed public walkie-talkies, with better fall resistance, waterproof, and longer communication distances.
Fujian Senhaix Electronic Technology Co., Ltd. has launched a Senhaix 8800 professional sports radio for the sports intercom market, and provides powerful features and hardware configuration beyond the general sports intercom and commercial machines.
This product not only has the transmission power performance of commercial professional radio, but also supports VHF/UHF dual-band operation and even includes FM radio and aviation band reception function, which is even as good as amateur radio in function.
Shape and design
Senhaix 8800 has an impressive appearance, from color to structural design and additional features that are markedly different from common commercial professional and amateur radios. It is designed specifically for sports applications and the outdoors.
SenhaiX-8800 has a bold, orange-red palette with black lines and keyboard accents. Foreign fire intercom specially used yellow and fluorescent green shell is the same reason. At the same time, its keyboard has a backlight, regardless of light and dark environment can be easily operated.
The shell of the Senhaix-8800 is made of a high-strength material, and the bottom of the shell is specially designed with a soft TPU material wrap, which can play a certain role in cushioning the fall and improve the anti-fall ability of the product.
At the headphone jack and battery contact plate, the Senhaix-8800 is designed with a rubber plug and apron to provide some waterproof function, enhancing the waterproof performance of the product.
The Senhaix 8800 also has a distinctive battery system design.
First, the combination of the battery block and the walkie-talkie is not the common pressing bayonet structure, but the use of a screw directly locked. This type of bonding is more secure, and the tightening of the screws increases the closeness between the battery and the body, which also improves the waterproof performance.
Second, the battery block itself comes with a separate Mirco USB charging port (complete with charging status indicator) that can be charged using phone in vogue chargers or even power banks.
The Senhaix-8800 has a simple top layout and only one volume/switch knob for operation. Knob around the larger space, on the one hand is convenient for the user easily use, another is convenient for the user to operate with gloves. Two way radio static Settings and power Settings are completed through the menu, and channel/frequency selection is performed through panel buttons, which can prevent users from misoperation and communication loss to a certain extent.
The Senhaix-8800 has an optimized, very distinctive and creative flashlight design on the bottom, and a dedicated flashlight button switch on the body. Senhaix-8800 flashlight brightness is much brighter than the general domestic commercial two way radio design on the top of the single LED flashlight, basically can meet the outdoor close distance road lighting.
Hardware and configuration
Apart from theSenhsaix-8800, we can see that the product has been specially strengthened in waterproof treatment. In addition to the waterproof ring on the shell, the exposed knob and the gap of the flashlight parts at the bottom of the shell are treated with waterproof ring and waterproof glue. The waterproof performance of the product IP55 is reliable. The wiring, PCB material and key components of the internal motherboard are good, reflecting the style of the domestic factory, but also the basic guarantee of product performance and durability.
The Senhaix-8800 supports dual-band reception and transmission of 136 ~ 174MHz and 400 ~ 470MHz, as well as 65 ~ 108MHz FM radio reception. In the official version of the product will also be added to the aviation band reception features, in order to increase the product in foreign sales function, as well as corresponding to the needs of foreign users.
In a more practical design, the Senhaix-8800 has a second PTT function, with a small PTT button under the main PTT for direct secondary frequency transmission.
Although the Senhaix-8800 is designed as a sports radio, it is still comparable to the mainstream commercial two way radio in terms of transmission power. The manufacturer provides 5W transmission power in both VHF and UHF bands. The actual instrument testing below confirms that the nominal transmission power is not unreal, and the transmission power is much stronger than that of the imported motion walkie-talkie, which also means that the communication distance is longer.
Special function
The Sebhaix-8800 leads its peers in the design of special functions, such as fast queuing function, Bluetooth write frequency function, and emergency alarm function.
The frequency scanning and quick grouping function of the Senhaix-8800 rapidly detects the working frequency of short range radios, including CTCSS parameters, and allows you to quickly join unfamiliar two way radio call groups.
The Senhaix 8800 write frequency can be achieved with a sleek Bluetooth wireless (optional) feature. After connecting with the mobile phone through Bluetooth, the frequency, channel, function Settings and other data can be configured. Cumbersome write frequency hardware configuration in the past is now a mobile phone can be done, anytime and anywhere can quickly write frequency.
The SOS alarm function of the Senhaix 8800 can send multiple alarm signals in an emergency. You can set local alarm and remote alarm items in the menu.
Performance measurement
The measured transmitting power of Senhaix-8800 is 4.6W with high power output and 3.0W with low power output in the 430MHz band, and 4.9W with low power output in the 144MHz band. The highest power output is no weaker than the mainstream commercial professional walkie-talkies on the market.
The sensitivity of Senhaix-8800 is very high. The measured sensitivity of the 430MHz and 144MHz bands is better than that of -123dbm, better than that of general commercial radios, and the same level as that of mainstream amateur radios. The Senhaix-8800 is equipped with an eye-catching received signal strength meter, a favorite feature of amateur radio enthusiasts and walkie-talkie players. The measured Senhaix-8800 shows 5 independent step displays, with the indicating range from -124 DBM to 104dbm.
The Senhaix-8800 provides excellent call performance, clear voice restoration, high loudness, and good effect in noisy environments. The menu design is simple and clear, and the whole menu comes with voice prompts, which is highly readable and easy to use.
Experience of use
For industry users, the Senhaix-8800 is easy to use, eye-catching in appearance and comfortable in hand. Various working modes are convenient for unified management and maintenance of sports team users, and not easy to misoperate. Its actual communication effect is good, whether the communication distance or voice clarity loudness, are not weaker than the commercial professional radio, and the anti-fall waterproof effect is outstanding, as outdoor use is also very good.
In general, the Senhaix-8800 is not only a professional sports radio, but also a crossover walkie-talkie. In terms of appearance and function, it is not only suitable for outdoor sports, but also suitable for hams to play. It is also perfectly capable as a communication tool for civilian rescue teams.
