The connection of the anti-fading circuit solves the technical problem of restoration of the original amplitude-modulated signal during interruption of the carrier non-modulated signal due to two-beam interference propagation in the short-wave tract earth-ionosphere. The gist of the connection of the anti-fading circuit concerns the fact that the input terminal /1/ is connected is connected with the input of the shaper /2/ and with the second input of the summation circuit /3/, the output of the shaper /2/ is connected with the first input of the summation circuit /3/, the output of the summation circuit /3/ is connected with the output terminal /4/. The connection of the anti-fading circuit can be used when designing receivers of amplitude-modulated signals.<IMAGE>
