LF: More earth-electrode antenna tests on 472kHz

[Roger Lapthorn <rogerlapthorn@gmail.com>]

Currently I am testing again with a 20m baseline earth-electrode antenna on 472kHz WSPR even though there is 8cm of snow on the lawn and ALL of the connecting wire is underneath the snow! There is absolutely nothing in the air at all. The attached photo shows the line of the connecting wire under the snow.

Already this afternoon I've had 6 unique reporters with best DX (so far) 126km:

2013-01-21 16:46	G3XBM/1	0.475641	-30	0	JO02dg	0.005	M0BMU	IO91vr	69	210
2013-01-21 16:46	G3XBM/1	0.475641	-27	0	JO02dg	0.005	G8ALS	IO92fk	126	279

2013-01-21 15:42	G3XBM/1	0.475693	+3	0	JO02dg	0.005	G0VQH	JO02fe	15	129
2013-01-21 15:42	G3XBM/1	0.475696	-10	0	JO02dg	0.005	G4KPX	JO02dj	14	0

Any reports would be appreciated.

Reports from G3XDV for example are only around 8dB down on the Marconi. I am using G3XBM/1 on the WSPR database to distinguish the earth-electrode tests from my usual Marconi vertical (the feed to my 10m halo) where I am using G3XBM.

ERP will be recalculated later based on actual S/N measurements of ground wave.
