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.

 

Unfortunately I didn't get any decodes here. This is not really surprising, looking at the DCF77 noise patterns on my WSPR-X screen http://dl.dropboxusercontent.com/u/26404526/wsprx_74614Hz_131213_0034.png 

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,
