Hi Diego,

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´t be discriminated by the extremely narrowband technics being necessary to see these weak signals at all.

QRSS1 won´t 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.

73,
