1KW All-solid-state PDM Medium Wave TransmitterPractice and Discussion of Frequency Change
The 909 radio station of Guangdong Province of programs with 1503KHz frequency have always been broadcast in standalone mode.In order to improve the security of broadcasting,other stations have been used to eliminate idle old transmitters for frequency change,thus forming a configuration mode of 1 master and 1 standby.To change the transmission frequency and maintain the long-term stable broadcast of the equipment is a very professional work,which requires a certain theoretical knowledge and practical ability.In this paper,the carrier frequency of 1KW all-solid-state PDM is changed from 1206KHz to 1503KHz as an example,and the analysis,calculation and adjustment of the frequency change process are described in detail for reference by peers
