attached some screenshots made from the audiofile which I recorded
during the reception. The "30sec dot" image shows the first dot of the
"V" after the CW 30sec long at about 05:00 UTC. At that time the
signal was not so strong as 15min earlier, but it shows exactly what I
meant. There are many gaps of rapid fading.
Rx was a Yaesu FRG100 with a 250Hz filter. 3 of the shots show the
full 250Hz range. The sideband-bursts could be seen in the upper parts
of the shot. Antenna was a double wire K9AY loop with a null of about
35dB in the direction of the DCF39.

In my earlier receptions of the QRSS3 transmissions from WD2XES and
WD2XKO I noted these type of rapid fadings, too.
Overall reception of these transmission was not very stable. I managed
to copy a few callsign strings and then lost the signal in a longer
fade.
