Well, your TX signal from the "big" antenna has absolutely no problem to cross the Alps, I could *hear* your signal sometimes during last weekend. We already had a 'solid copy' QRSS qso (I think while we were waiting for RU6), with a bit of luck even a normal CW QSO could be possible.

Did you consider to build a loop with adjustable 'elevation' ? A system of two orthogonal loops may be helpful in an experiment to find the elevation. 
Markus (NM) has a very interesting RX system for azimuth detection on a waterfall which may be modified to detect the elevation of a signal. I am planning to build such a system based on his plans (and software) as soon as possible.

Good luck,

P.S.: About the crude Hell letters from DF0WD which looked a bit like "Lego blocks":
I used a simple 'sequential single-tone' Hell signal, while Markus transmitted in Chirped Multi-Tone hell which gives a nicer spectrum and allows narrower bandwidth without smearing. But you need a quite linear TX for it, otherwise the important amplitude shape gets lost.
