Hello Markus and group,

Thanks for the interesting spectrograms... I especially like that 
camouflaged loop in the garden.

... and to you for painting those eggs in various colours on your 
LF-RDF-spectrogram. Guess you were out in the garden at that time, and 
moved the loops ?

Will be interesting to see if that directional VLF fading is related to 
the time of day, or if you caught a SID event by chance, and if similar 
things happened on LF the same time.
My own bearings of the new 18.5 kHz transmitter only vary by a few 
degrees, but  I'm just 8 wavelengths away from it ;-)

73, Wolf  DL4YHF .
