摘　　要：文中从分析天调网络的结构组成与设计方案入手,针对10kW全固态中波发射机在运行过程中存在的邻频干扰、输出网络故障等问题进行调试方案与具体实施步骤的研究。通过分别调整并联谐振、串联谐振,更换受损元件后重新进行输出网络结构的调整,最终成功解决信号干扰、网络失谐故障,为发射机运维工作提供重要参考价值。Starting with the analysis of the structure composition and design scheme of antenna tuning network,this paper studies the debugging scheme and specific implementation steps for the adjacent channel interference and output network failure of 10kW all solid-state medium wave transmitter.By adjusting the parallel resonance and series resonance respectively,and re adjusting the output network structure after replacing the damaged components,the signal interference and network detuning faults are finally successfully solved,which provides important reference value for the operation and maintenance of the transmitter.
