In order to overcome the problems of tedious generation process,difficult and unscientific frequency point selection,this paper proposes a method of scientific frequency selection and fast generation of contact file.This method collects the parameters of the contact file such as the longitude and latitude of the receiving and sending places through the program,calls the frequency selection software V,calculates the frequency,antenna angle and other data in combination with the sunspot data of the past few cycles,generates the contact file automatically by COM technology,and generates other contact file parameters automatically by pseudo-random number generation method.The results show that using the software made by the method proposed in this paper to make the contact document,the work intensity is reduced.In addition,the antenna erection height and other parameters that the original contact document does not have can guide the follow-up communication work,and the communication passability is greatly improved.
