Genossen, MF,

For such distances on 630m i would recommend not to go slower than 
QRSS-10. Years ago i've been detected by WA3TTS. Unfortunately i can't 
find the spectrogram he sent me (over the reflector) but the DFCW signal 
was quite blurry. Still good readable but the permanent QSB was clearly 
visible. QRB is/was about 6600 km.

73, Stefan

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´t be discriminated by the
extremely narrowband technics being necessary to see these weak signals
at all.<br>
      <br>
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.<br>
      <br>
73,<br>
