So there is, better tonight ...
Attached one Argo screenshot. Receiver at 472995 @ CW tone = 750
Hz.
Hi all,
plus 10 Hz from South America to Europe - that´s the final proof
how fast earth is spinning!
No kidding: if Marcus even heared Diego at 472995 +/- 1 Hz then
it seems I saw some other weak DX signal. Anyway, by searching a
little bit off-center on the Perseus screen I certainly not have
been fallen again for Perseus´ occasional weak
mid-screen-artifact (DK7FC, DF6NM: you know it from my former
enthusiastic VLF report ;-) ) ....

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,
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.
