RRR Stefan, if you could slide up a few Hz that
would be great....& tnx for Dst link.

Mike,
Interesting to read about your RX equipment.
Sounds like a bit effort but must be a great fun as well :-) I like the
different antennas, and i'm glad to read that there is interest to get my
signals.
Well, you could have asked to QSY a bit, so i'm not right on your
QRM traces. Or would this be some kind of cheating?
Maybe it's a good night
again, graphs on http://lasp.colorado.edu/space_weather/dsttemerin/dsttemerin.html
look quite promising...

Markus: I do not think the QRM signals
are spurious. I have built the W1VD preselector for 475~500 kHz range and
the offending signals are still present when the preselector is used.
Same with the FZ-02 filter. There are some commercial and retail shops
to my NE about 300~400 meters away, possible that is the source.
However, the offending QRM signals are not consistent in frequency or
strength from one day to the next. QRM signals are not very strong,
but strong enough to interfere with a -27 to -30 SNR desired
signal.
I use a pair of crossed EWE antennas to
have four-way selectable cardio patterns for NE, SW, SE, and NW directional
reception. If I switch to the NW direction, the QRM signals go away, but
then directivity to DK7FC would be about 4~5dB down. To the SW and SE
directions some QRM sources disappear, and other QRM sources appear. I
may try some phase steering between the two EWE antennas. It is an
ongoing learning process. Random chance could always prevail, so I continue
to listen, tinker, and occasionally even learn something ~:). 73,

PS: I have received several F5WK wspr2
captures on 630m this last December....

Looks like Stefan ran into a Loran
line... but wait, Loran is no longer there in North America, and
anyway we're on MF not LF. Mike any idea what is causing those
spurs?
