摘要
某小型飞机通信系统超短波电台工作在130MHz时,出现持续的强噪音现象,静噪开关打开关闭,噪音状态无变化。针对这一故障现象,详细研究了故障的产生机理,结合原理对故障进行了分析。在此基础上,就130MHz频点受干扰问题制定了详细的实施方案,最终结果证明了所述方法的有效性。
When the ultra-short wave radio of a small aircraft communication system works at 130 MHz, contin- uous strong noise phenomenon occurs. The squelch switch is turned on or off, the noise state remains un- changed. Aiming at this fault phenomenon, the fault mechanism is studied in detail, and the fault is analyzed in combination with the principle. On this basis, a detailed implementation plan was formulated to solve the inter- ference problem of 130 MHz frequency point. The final results prove the effectiveness of the method.
