Abstract:DF100A 100 kW shortwave transmitter tuning system plays an important role in the transmitter. It controls the frequency of the excitation signal corresponding to the output of the frequency synthesizer,and can complete the setting of the fixed position of 10 preset tuning channels,so as to realize the coarse and fine tuning of the tuning elements. It can be seen that the position of each tuning element determines whether the transmitter can operate normally and stably,and directly affects the safe broadcasting work of the radio station. Therefore,through the research on the tuning system of DF100A 100 kW shortwave transmitter,a standard teaching and testing platform for DF100A 100 kW shortwave transmitter tuning system has been developed and set up. The composition,main contents, characteristics and application of the platform are mainly introduced.
