Hi Marc, Valerio, Wolf and Group,
saw Marc's QRSS yesterday evening near 137687, 19:40 UT "M" (-6 dBuV/m) until
20:30 "O" (-3dBuV/m). Tried to call, but in vain, not enough ERP here (30mW).
Today 9:00 he was "O" at -14dBuV/m in low noise level, with G3AQC who was "O"
-4dBuV/m.
The line at 137689.6 Hz is also visible here most of the time, but as it does
show some fading, it does not seem to originate from the DCF transmitters.
Interestingly, a while ago Walter DJ2LF and I observed that the troughs do
not occur simultaneously at our two QTH's, 20km apart.
Other stn's heard today in JN59NK (call: dBuV/m):
DF0WD: +14, M0BMU: +3, OK1DTN: +20, OM2TW: -3, DL3FDO: +23, IK5ZPV 60W:
-5...-2, IK5ZPV 100W: +3 .
After reading Stewart's interesting message, I immediately upgraded to WOLF
0.53. Tnx Stewart, it's a pleasure, all the new features work perfectly! In
the evening I saw Wolf at DF0WD testing his WOLF, and we had a nice QSO. It
ended up as something like a one-and-a-half-way-PSK: I tried to correct his
TX-freq offset with -f 2016 Hz, but decoding failed completely. After some
experimenting, it finally occured to me that I would have to correct the
bit-timing as well by modifying my samplerate -r to 0.82% below its usual
value, and bingo - there he was. When I called agn, noise and
Luxembourg-effect QRM had gone up so much that we had trouble hearing each
other in CW ...
