Decoded at Bielefeld via DL4YHF (303.8km).  Copied 'DK7FC' with
Eb/N0 +4.5 dB and constant reference phase.

S/N 19.1 dB in 29.8 uHz, -60.1 dB in 2.5kHz.

I'm still working on the recordings from the weekend.  Gained a further
3dB by using very strong hum filtering, a threshold only 1.5 times the
mean amplitude and narrow notches.  Enough to suppress not just the
harmonics but also the sidebands of the harmonics.   Still no trace
here in Todmorden - yet.  Still some permutations of polarisation
and azimuth to try.

A daytime thunderstorm near Heidelberg would do nicely.
I can use the sferics to measure polarisation and E/H ratio.
That leads directly to an optimum antenna mix.

We are having fun with this!  Constantly pushing at the limits.
