| 摘 要： | 在８８２Ｆ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。

Analysis on the little deviation of the receivered signal freguency in making up the receiver of 882F freguency modulation |
| |
| Abstract: | 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. |
