Henny,
thanks for this good capture,
showing Bob's signal squeezed in between the QRM lines. It's a
bit more difficult than Opera because WSPR-15 requires about 0.73 Hz
clear bandwidth. We should also note that the "nominal WSPR
frequency" seems to be not the center but the lowest of the four
tones.
which hardly changed during the course of the
night.
Probably my best bet would be to ask Bob to go to
74603.6 Hz. Then the tones would sit in a DCF minimum,
and also be well above the nearest Loran line (74603.2804 Hz from
Sylt), thus should be pretty clear everywhere in Holland, the UK, and
Germany:
Best wishes,
Markus (DF6NM)
