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.

I can use the sferics to measure polarisation and E/H ratio. That leads directly to an optimum antenna mix. > We are writing radio history, a bit, at least it feels a bit > like that in the moment. We are having fun with this! Constantly pushing at the limits. -- Paul Nicholson --
