CT-3电台采用了遥控调谐系统,使电台能自动调谐,使用很方便。但整个系统的组成,工作过程都是比较复杂的,而且故障率比较高。本文根据部队 CT-3电台遥控调谐系统发生的故障,从故障的分析、排除,及如何维修作一阐述。1.在检修部队 CT-3电台故障中,曾遇到电台调谐不停的故障,这时能听到调谐电机有节奏的在转动。电机转动声有两种:一种是转动声的周期比较短,约0.5秒;另一种是转动声的周期比较长,约4～5秒。在分析检查中,发现其根源是扇区电门拆下做完清洁工作后,安装时不注意,将扇区
CT-3 radio remote control tuning system that allows the radio to automatically tune, easy to use. However, the composition of the entire system, the working process is more complicated, and the failure rate is relatively high. According to the troubles of the remote control tuning system of CT-3 radio unit, this article makes an elaboration from the analysis, troubleshooting and maintenance of the fault. 1. In the maintenance unit CT-3 radio failure, has encountered constant tuning failure of the radio, then you can hear the tuning motor rhythmic rotation. There are two kinds of motor rotation sound: one is the rotation of the sound is relatively short period of about 0.5 seconds; the other is the rotation of the sound relatively long period of about 4 to 5 seconds. In the analysis and inspection, found that the root cause of the sector door removed after cleaning work done, the installation does not pay attention to the sector
