        Hi Diego,<br>
        <br>
        do you know the exact QRG of your last transmissions? During the
        night from 20181016 to 20181017 I repeatedly saw faint traces
        with QSB at 473.005 kHz (+/- 1 Hz after calibration) at the
        Perseus SDR at DL0AO with the 200-m-Beverage to South America.
        Sadly a doubtless identification was impossible - 8 WPM CW can=C2=
=B4t
        be discriminated by the extremely narrowband technics being
        necessary to see these weak signals at all.<br>
        <br>
        QRSS1 won=C2=B4t help really - you should try to modify your
        transmissions to QRSS 20 or 30 or preferably (if possible for
        your TX) DFCW 30 with 2 or 3 Hz shift. The characteristic
        pattern of DFCW would make the identification much more easy.<br>
