Hi Warren,

You may also forward the latest email to him, that one which shows Jay's=20
results and the link to the grabber and so on.

Martin has a 80m long wire in maybe 8m above ground. This wire is
resonated to LF and transformed to the RX input impedance by using a
ferrite rod. A separate LF earth is used. The RX is that one by JA8SCD,

&nbsp;(also used by TF3HZ and DU1GM and others). He also has a tuned loop
antenna with about 8 square meters cross section area. I guess its
mostly beaming to NE/SW. Furthermore he built a E-H-combiner to
optimise the SNR even more. There was a 3 dB improvement in some of the
tests.<br>
I don't know exactly what he is using these days but i guess the system
is not particularly optimised for best US reception. Maybe there could
be a few dB more S/N...<br>
    <br>
What about WE2XEB? Is that not a motivating goal for him to leave
traces in SA, using traditional QRSS or DFCW? He would surely make that
distance, not to talk about EU receivers...<br>
