近五年来,为了实现扩大覆盖和实验任务,广电总局实施了对中、短波广播发射台的一系列改、扩建工程,使得许多电台的发射能力翻番提高,技术设备的科技水平得到很大的提升。对于中波台,由于几乎都更新为全固态数字调制的发射机,单一频率工作,设备稳定性和运行可靠性较高,因此不少省市级发射台建立起了通过专用网络集中远程监控所辖发射台,实现了利用科技手段提高安全播出的运行管理能力。对于大功率的短波发射台,改造
In the past five years, in order to achieve the task of expanding coverage and experimenting, SARFT implemented a series of alterations and extensions to medium- and short-wave radio transmitting stations, doubling the transmitting capability of many radio stations and greatly improving the technological level of technical equipment . As for the medium-wave station, since almost all transmitters are all-solid-state digital modulation transmitters, single-frequency operation, equipment stability and operational reliability are high, many provincial and municipal transmitters have established centralized remote monitoring stations Administering the launch pad, to achieve the use of scientific and technological means to improve the safety of broadcast management capabilities. For high-power short-wave launch pad, transformation
