0.前言随着世界进入信息时代,广播事业得到了迅速发展,我国中波广播发送设备已走向全固态数字化。我台也于1999年从上海广播科学研究所购进了第一台10KW全固态数字式调幅中波发射机作为新闻广播的主用发射机。到目前为止,我台已有5台10KW全固态数字式调幅中波发射机。十多年来,数字式发射机也给我台技术人员带来了许多棘手的问题,但我们都克服了困难,查图纸、找资料,刻苦钻研,所有的故障都是由我们自己找到并排除的。同时我们也积累了一些数字

China’s medium-wave broadcasting and transmitting equipment has moved toward all-solid-state digitalization. I also Taiwan in 1999 from the Shanghai Institute of Broadcasting Research purchased the first 10KW all-solid-state digital AM transmitters as the main news broadcast transmitter. So far, our company has 5 sets of 10KW all-solid-state digital AM mid-wave transmitters. For more than a decade, digital transmitters have also brought many troublesome issues to our technicians, but we have overcome the difficulties, looking up drawings, looking for information, assiduously studying, and all the failures are discovered and excluded by ourselves of. At the same time we also accumulated some figures
