摘要
在 8 8 2 F调频接收机组装过程中发现 ,调频接收频率偏小。理论分析知道 ,其原因是调谐本振线圈电感偏大。理论上也探讨了本振线圈的匝数值。实际处理后 ,调频收听效果良好。
We have discovered that the signal freguency receivered driffes off and small in making up the receiver of 882F freguency modulation. Through theoretical analysis, we know the cause is the inductance L of tuning local oscillation being bigger. At the same time, we have theoretically given out the foldnumbers of local oscillation coil. Having been practically handled, the receiver is very effective.
