SHORTWAVE RADIO COMMUNICATION SYSTEM Russian patent published in 2017 - IPC H04B7/00 

FIELD: radio engineering, communication.

SUBSTANCE: in each receiving facility of the shortwave radio system a calculator is introduced, connected to the two-way communication with a database with external input, the generator of control signals of all the reception paths, the multipath device for receiving and processing the HF signals with the receiving antennas and the control and display unit, k calculator inputs are connected to the k outputs of the multipath device for receiving and processing the HF signals with receiving antennas, and its k outputs - to the k inputs of the corresponding driver of the control signals of all the receiving paths, the (k+1) output of the calculator is connected to the control input of the receiving path switch.

EFFECT: organizing a shortwave radio communication system consisting of N interconnected radio communication stations, automatic control of the receiving center switch operation with the help of a calculator, choosing a probability-optimal frequency by scanning one of the n receiving paths controlled by the calculator to adapt the system.
