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...
