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。
In the 8 8 2 F FM receiver assembly process found that FM receiving frequency is small. The theoretical analysis shows that the reason is that the inductance of the local oscillation coil is large. In theory, the number of turns of the local oscillation coil is also discussed. After the actual treatment, FM listening good effect.
