Can a Class A Radio License Install a Vehicle-Mounted Radio?
3 Answers
Radio a certificate can install a vehicle-mounted radio. The 7900 has a transmission power of 50W and requires a Class B license. A Class A license can only use models with less than 25W. Below is an introduction to vehicle-mounted radios: Understand the facts: Vehicle-mounted radios can usually be used to monitor traffic police frequencies, offering many benefits. They provide real-time updates on situations, such as special operations happening today—whether they are targeting lane violations or overtaking; which road sections have accidents or traffic jams, etc. They can also prevent theft: Using a vehicle-mounted radio for theft prevention involves connecting a dual-tone decoder to the radio's audio output port, driving a multi-contact relay. The relay can cut off or short-circuit necessary circuit parts when activated, controlled by a handheld walkie-talkie transmitting dual-tone codes, with a range of several kilometers.
Well, for friends holding a Class A amateur radio license who want to install a mobile radio in their car, I can share some insights. As someone who frequently engages in mobile radio operations, the Class A license, being an entry-level certification, does legally permit the installation of a mobile radio. However, there are conditions: the device power must not exceed 25 watts, and the frequency range is restricted to specific amateur bands, such as the common 144MHz or 430MHz ranges. Before installation, it's mandatory to apply for a station license from the local radio management authority and submit the equipment parameters for review; otherwise, it's considered illegal operation. For installation, it's advisable to place the mobile radio in the trunk or under the center console, with the antenna ideally mounted at the center of the roof to prevent loosening and driving noise. I recommend beginners opt for reputable brands like YAESU and have the installation done by a professional shop to avoid circuit damage from incorrect wiring. In daily use, adhere to communication protocols by keeping conversations brief, prioritize driving safety, and avoid unnecessary chatter on highways. Regularly check the tightness of the antenna screws and the condition of the feeder cable to ensure stable signals without interfering with other electronic systems. This way, you can enhance your driving enjoyment without risking penalties for non-compliance—it's really practical.
After obtaining the Class A amateur radio license, I immediately installed a mobile radio in my car, and the experience has been fantastic. As an average car owner, the process isn't overly complicated: First, visit the radio administration to apply for a station license with your equipment details; then purchase a mobile radio under 25W—higher power requires a higher license class. For installation, I enlisted a friend's help, mounting the antenna on the roof with a magnetic mount. It's great for communicating with nearby ham friends while driving, especially during road trips for added safety and emergency support. Key tips: Stick to amateur frequencies—no casual chatting to avoid distraction; ensure the antenna is securely placed to prevent noise at high speeds. I check connections weekly for looseness and keep the equipment clean to avoid dust buildup. Beginners should avoid DIY battery wiring to prevent short circuits—professional installation is safer. Overall, the Class A license simplifies and secures mobile radio use, adding a fun dimension to driving.
