CONNECTION OF TELEGRAPHICAL RECEIVER

摘要

Connection of the telegraph receiver resolves a technical problem of effect suppression of ionospheric signal two-ray propagation on telegraph signal fall-out. The essence of connecting the telegraph receiver rests in the fact that the input of a squarer (4) is connected to the output of the first intermediate-frequency circuit (1) and to the first mixer (2) input provided that the squarer (4) output is connected with the mixer (2) output and with the input of the second intermediate frequency circuit (5).<IMAGE>
