Common faults and solutions of VHF marine radio in daily use
In recent years, with the vigorous development of water industry, water traffic is more and more developed, communication safety is more and more important, and the use of maritime radio is more common. Summarize some of the most common faults and solutions in daily use for users' reference.
Battery: battery is the power source of the whole maritime radio. Due to the large current when the VHF marine radio is transmitting, the battery performance is required to be high, so lithium batteries or rechargeable Ni MH batteries are often used. In the process of using, users often respond that the battery is not used for a long time. In addition to the inferior batteries used by individual brands, there are also some mistakes in the way they are used. Some users charge irregularly in the process of using, such as charging while using, charging at random for a period of time to pick up and use, etc., there is no regular charge and discharge. However, no matter what kind of battery, in the process of irregular charging and discharging, the battery capacity will be greatly reduced, so the radio will soon appear the phenomenon that the battery is not durable. At the same time, marine radio is generally used in the river or sea, the environment is humid. If you don't pay attention in the process of using marine radio, it will corrode the battery and cause leakage.
Antenna: users often use that antenna to drive the whole VHF marine radio. What's more, pinch the tail of the antenna to swing the radio. As the antenna port is the high-frequency receiving and transmitting port of the whole machine, professional TNC, BNC, SMA and other interfaces are often used. At this time, due to the mechanical strength of the antenna itself, over time, the antenna skin will fall off, the antenna pin will break, or the contact surface of the antenna pin will become smaller. In serious cases, the joint between the antenna pin and the circuit board will be desoldered. It is suggested that you should pay attention to the correct use method when using the antenna. Check whether the connection between the antenna and the antenna base is reliable, whether it is blackened or dirty, and whether the appearance of the antenna is damaged. If it is damaged, it is recommended to replace the antenna and the antenna base of the same model.
PTT key: the launch key is the most frequently used part in daily use. In some repair machines, it is found that the rubber outside the launch key is aging or damaged, which affects the normal use. Some of them affect the buttons on the circuit board, such as poor contact and failure of buttons. It is better to use the same type of device as the original machine when repairing.
