Decreasing the tuning time of the antenna is very important in intelligentized and automated short-wave adaptive communication systems. An improvement scheme of a sort of short-wave transceiver automatic antenna tuner is given by illustrating the development of software and hardware. The result of experiments indicates that the tuning rate of the improved antenna tuner is enhanced prominently. The scheme will improve the tactical performance of a sort of short-wave single-side-band transceiver and demonstrate great economic value.
