1.前言为了解决中波波段频率拥挤的问题,我国于1979年11月实行了中波同步广播的政策。此后,各省相继建起了中波同步广播网。但是,各地在管理上和技术上都存在着不同程度的问题。有些地方由于标频传输问题未解决,没有能实现中波同步广播,或虽
1. Introduction In order to solve the problem of frequency congestions in the medium-wave band, China implemented the policy of medium-wave synchronous broadcasting in November 1979. Since then, the provinces have successively set up the China-Poland Synchronous Broadcasting Network. However, there are varying degrees of management and technical problems in various places. In some places, due to the issue of standard frequency transmission is not resolved, can not achieve synchronous broadcast of the wave, or
