Oh, i just saw that Halldór is running his QRSS-3 window arround my OP
TX frequency.
Right now i got:
23:16 136 DK7FC de TF3HZ Op8 2438 km -27 dB in Reykjavik
And the spectrogram is attached. For me that looks like another
confirmation that OP8 is about like QRSS-3, maybe 1 or 2 dB better. It
takes twice the time to send my call in OP8 so it is more or less
equal. From that point of view i'm impressed by the good results of
4X1RF and UA4WPF.

OP8 tests , with the odd day time decode to TF3 ...may be
running OP32 , would decode at TF3 during the day ,, he could
be just under the s/n limit using OP8
Graham, take a look at Halldór's grabber
http://simnet.is/halldorgudmunds/TF3HZ_LFgrabber/
The wideband window gives an idea of the strength of DCF39 and so about
the propagation from Germany. You can see that the signal is strongest
arround 0...2 UTC. There you can also see a trace of my transmissions
in the spectrogram to that time on 137.71 kHz
But there are times in the afternoon, e.g. 11 UTC, where DCF is strong
too. So this would be a slot for OP8 or QRSS-3...
