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.

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.
