China News Service, September 20th. The National Day Golden Week is coming. It is rare for such a long holiday. Presumably, most people will travel by self -driving tour. In fact, this is also a stylish way of travel. When traveling with each other, each car can be contacted in time. After all, in the state of driving, a high -speed entrance may be missed in seconds. Due to the timely congenital advantages of communication, radio walkie -talkie has always been the best communication tool for self -driving tour, none of them.
However, there is a problem with handheld intercom, that is, due to power restrictions, the distance may affect the communication effect due to the range. At this time, installing a more power -on -board radio intercom (hereinafter referred to as “car radio”) is the best improvement plan. I am a self -driving tour and off -road enthusiasts, and is also a radio enthusiast (HAM, call signal BH1VSA). Many years of self -driving tourism proves that the vehicle radio station does bring higher communication efficiency to the traveling travel. Especially in the wild with weak mobile phone signals, the vehicle -mounted radio station with sufficient power is a kind of rescue communication tool to provide guarantee for timely rescue.
Recently, Teimo has come into contact with a car radio station to recommend it to everyone. The reason for the recommendation is that this radio station is not only within 1,000 yuan, but also rich functions and reliable performance make it cost -effective. At the same time Introduction users. This car radio station is the VR-6900 launched by Wizhizhi.
The official launching two color panels, black and fluorescent green, we tried this time with fluorescent green. This version is to have better recognition in complex environments in emergency communication.
First of all, aspect of the appearance, the VR-6900, as a vehicle radio station, is relatively different from the conventional car radio station on the market. It adopts a pioneering and refined design. Even the senior HAM may not think it is a radio. However, the appearance of personality is a highlight of Wino VR-6900, and this is the original design of Wino, which breaks through the spell of domestic radio imitation plagiarism, which is worthy of praise. In terms of materials, the panel uses engineering plastics, which has excellent performance in high and low mild wear; the whole aluminum alloy casting body has better heat dissipation and stability.
Open the VR-6900, the biggest convenience is the operation of the entire Chinese menu, which is good news for entry users. All names and settings options are displayed in conventional Chinese, and the menu setting logic is also concise and complicated. Essence In addition, Chinese inputs can be achieved by hand microphone, such as setting the Chinese name without writing frequency software.
During the use, the Weinuo VR-6900 panel integrated the loud horn is rare in the models within a thousand yuan. The 50mm high-sized high-fidelity speaker is more directly passed out. The conventional vehicle radio speakers are set on the host. If the split is installed, the voice will be covered by the installation position (generally installed under the seat or trunk), and it also needs to be connected to the outside speaker. This will not only increase the installation construction construction construction The amount also increases costs.
In terms of frequency indicators: Weinuo VR-6900 can receive 78-108MHz FM radio, 108-136MHz aviation band, 136-174MHz V section, and 350-520MHz U section of amateur frequency bands; the launch is 144-148MHz and 430-440MHz. UV amateur frequency band (extended full section launch). In terms of launching power, it provides a three -gear transmission level of 8W, 20W, and 50W (U -section 40W), and can switch the power through the panel button according to different usage scenarios. We use the HP8921A comprehensive testing equipment. The maximum power of 430MHz in the U section can reach 47W, and the maximum power of 144MHz can reach 51.1W.
Another HAM favorite spectrum function (Scope) is also the highlight of the VR-6900. In this price range, no radio has this function. This function can be searched according to the set frequency of the settings, and the signal status around the current center frequency is searched. You can also search for spectrum according to the frequency band mode to search for the signal status around the current frequency band. You can also search for spectrum according to the channel and search for the signal status in the current channel area. The spectrum function can be used not only for monitoring, but also to read frequency. For example, when you meet your teammates when you travel, you do n’t know that your radio frequency (the frequency intercom without keyboard and screen), you can read the frequency through this function.
In addition, the APRS function VR-6900, which is rare in this-level car radio, also supports it, but you need to buy another APRS kit to travel, and your position is clear at a glance with his teammates.
Timu uses a split installation to the vehicle to fix the panel to the front windshield with a split type. The Vino’s original bracket has a large suction viscosity. Adhesion does not affect suction cups. The flexible point is that the VR-6900 panel and the host have a hand mimether, which means that the hand mimes can be inserted on the panel or the host, which is more convenient for the flexible split installation in the car.
Of course, when you put it at home for a fixed table, the volume of VR-6900 will not account for too many places. When used as a fixed table, the panel and the host can be installed together.
At present, the VR-6900 is priced at 969 yuan in the official Taobao store. If it is recommended to buy suction cups and extended line suits if it is installed in the vehicle split, it is only 1027 yuan. The important thing is that in the car radio station at this price, it is rare to have the functions and configurations of these professional equipment. For a self -driving tourist, two boxes of oil money can solve the problem of radio communication, and this expenditure can basically be ignored.
In terms of horizontal comparison, whether it is domestic or imported radio products, the VR-6900 in this price range can completely reflect the sincerity of the manufacturer, and the cost-effectiveness is also a well-deserved first choice. Faced with the phenomenon of “short two shorts” in some products, the power of VR-6900 can be regarded as conscience. The main thing is the richer amateur radio function, which not only meets entry users, but also becomes the new favorite of old HAMs. And Winno ’s many years of overseas market experience also provides an endorsement for VR-6900 high quality.
(Note: In accordance with the law, users who are except for civil radio (that is, the frequency of 409-410MHz, except for radio stations with a transmitting power of 0.5W) need to obtain the “amateur radio operation certificate”, and the equipment needs a “wireless radio license”, the side Can be launched.)
