Hi all

I saw some faint lines on Argo and some aural copy at 472995 on SDR-IQ 
(good ~1Hz).

Alejandro LU8YD have the same freq reading using Perseus.

      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>
