摘要
本文从分析凯里小高山发射台存在的问题出发,指出了对发射台10套调频广播建设多工共馈发射系统的必要性和紧迫性;分析了在多频点低间隔条件下,建设调频十工系统的技术难点,并结合发射台实际,提出了全面系统的设计思路和解决方案;详细介绍了调频十工系统的组成、技术重点创新和测试参数等。目前,该系统已建成并稳定可靠地运行一年有余,结合测试参数分析来看,技术项目的升级改造是成功的。
With analysis of the existing problems in the Xiaogaoshan transmitting station of Kaili, this paper points out the necessity and urgency for construction of multiplex feed launching system for FM radio of ten sets. It analyzed technical difficulties of building the FM multiplex system under the condition of Multi-frequency points with lower interval .Combined with the transmitting station＇s reality, it proposed design ideas and solutions, Also the paper introduces FM multiplex system composition, technical innovation and test parameters. At present, the FM multiplex system has operated for more than a year. According to the analysis of the test parameters, the upgrading of the technical project is successful.
