1、一、986A 型对讲机介绍 986A 对讲机是一种近距离的、简单的无线传输通信工具。目前，它广泛应用于生产、保安、野外工程等小范围移动通信工程中。方便实用。发射频率为 49.8MHz，电路简洁，制作容易，具有遥控距离达100 米以上。二、电路的工作原理电路工作在发信状态时，S2收发转换开关按下置于“发信”位置，由扬声器将话音变成电信号后由电容器C17耦合到 Q2 Q3 Q4 Q5和相关电阻电容等组成低频放大电路放大后，经耦合可调电感的中心抽头将信号加到振荡管Q1进行信号调制，使该管的 bc 结电容随着话音信号的变化而变化，而该管的bc 结电容是并联在T1次级两端的，所以振荡电路的频率也随之变化

2、，实现了调制的功能，并将已调波经T1及 L1 从天线发射出去。电路的接收：三极关Q1和耦合可调电感T1、电容器 C4、C2等组成振荡电路，产生频率约为49.8MHZ的载频信号。Q2、Q3、Q4、Q5和相关电阻电容等组成低频放大电路。扬声器SP兼作话筒使用。电路工作在接收状态时，被收/发转换开关置于“接收”位置（默认状态为接收），从天线 ANT1接收到的信号经天线匹配电感L1、再经可调耦合电感线圈 T1、电容 C4、C2、高频三极管 Q1及 T1次级线圈等组成的检波电路进行检波。检波后的音频信号，经T1次级线圈中心抽头耦合到低频放大器的输入端，经放大后由电容器C17耦合推动扬声器 SP发声。精品

31、它们焊牢。在调试时如果只能发送不能接收则检查接收电路，用万用表逐点测试找出错误点并改正；如果只能接收不能发送则检查发送电路，用万用表逐点测试找出错误点并改正。如果既不能发送也不能接收上面两部分都要照做。最后在验证对讲机的性能时，也应该考虑外界环境因素的影响，天气、地形、建筑物、电磁干扰等都会影响信号的场强和覆盖范围。当电池电量不足时，通话质量也会变差，严重的会有噪声初相，影响正常通话。十、总结和心得体会通过这次对讲机的组装和焊机的实际操作，我对电子技术有了更深刻的认识，这次的实训也让我了解了焊接的操作方法和技巧。在组装的过程中遇到了一些困难，通过自己查询资料和同学的帮助下，增长了的知识。精品资
