Stefan,
    I forwarded your message to Bob W2ZM (WE2XEB, WE2XGR/6) to see if wants
to try QRSS on 137.
Bob has had trouble getting signed up with this rsgb list (maybe an ISP
problem?) so I have been forwarding messages from and to him.

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, <a href=3D"http://=
icas.to/lineup/idc-136-kit-eng.htm" target=3D"_blank">http://icas.to/lineup=
/idc-136-<u></u>kit-eng.htm</a> =A0(also used by TF3HZ and DU1GM and others=
). He also has a tuned loop antenna with about 8 square meters cross sectio=
n area. I guess its mostly beaming to NE/SW. Furthermore he built a E-H-com=
biner to optimise the SNR even more. There was a 3 dB improvement in some o=
f the tests.<br>

I don&#39;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, no=
t to talk about EU receivers...<br>
