摘　　要：在全国地面数字电视700 MHz移频工作实施之际,许多台站淘汰了原有发射机。通过对发射机的工作频率进行调整改造,这些发射机即可作为新频点的备机投入使用。频率改造工作涉及多个方面。以浙江丽水广播电视台的改造工作为例,阐述主要改造内容,为后续改造提供经验与建议。When the national terrestrial digital television 700 MHz frequency shift work is implemented,many stations have eliminated the original transmitter.By adjusting the working frequency of the transmitters,these transmitters can be put into use as the standby of the new frequency points.Frequency transformation involves many aspects.This paper takes the reconstruction work of Zhejiang Lishui Radio and Television Station as an example,expounds the main contents of the reconstruction,and provides experience and suggestions forthe subsequent reconstruction.
