Dear Ossi, Markus, LF Group,

I was quite interested to notice the sharp dip in OE5ODL's signal at around 1430utc today, and in light of Markus' comments, I used the cursor facilities in SpecLab to manually read off the signal levels, avoiding the noise bursts. I also did a quick field strength calibration of the loop/receiver - the resulting plot of field strength vs time is shown in the attachment (the vertical axis should say "dBuV/m"). As well as the deep null around 1430, the signal level seems to rise several dB during the day, peaking around 1800 - 2000, and now starting to fall off. Also, a downwards drift in frequency of about 1.5mHz can be seen.

Cheers, Jim Moritz
