Moin Markus,

Just came across at an excellent web paper by Micha Sanders (PC4M, PA3BSH)
http://misan.home.xs4all.nl/eclipse.htm, dealing with observations of the
HBG 75 kHz time signal during the 1999 solar eclipse. Most observers found
a characteristic W-shaped fieldstrength curve, with a central maximum
preceeded and followed by two minima. This was found to agree very well
with a simulation based on local D-layer height variation around the moon's
shadow.

Mentioned in the article but not shown in this version:

The reason was, that I used a different method:
selective level meter and DVM with serial output.
