I've tried E-field only, and H-field only in various combinations of linear and circular polarisation. The sferic blanker is working quite well I think. Still no trace of the signal here. But tweaking the blanker isn't going to go from 'no trace' to 'significant detection'. > What do YOU need to get a first trace of my signal in the UK? Perhaps I need to move 1/2 wavelength nearer or further? Maybe the sky wave and ground wave are just nicely cancelling out? > Would you do the decode work for me if i try to leave my > call over 3 wavelengths on ULF? Sure. Your chosen settings look OK so long as the signal at Bielefeld is as good as the 21st. It doesn't seem very repeatable, Friday 20th signal was not so good - 6dB weaker and with a large phase difference too. 162 degrees on 20th and 63 degrees on 21st. But on 20th there were three occasions when the Bielefeld timestamp stepped backwards by one sample, which adds up to the extra 100 degrees. Probably accounts for the 6dB loss too. So give the 5 chars a try. If there are not too many timing glitches I can probably adjust for them. -- Paul Nicholson --
