Content preview: Thanks for the first overview. A very nice signal in Bielefeld
indeed. Also the RX site at DL0AO shows the signal with a very good SNR in
424 uHz, http://df6nm.bplaced.net/dl0ao/VLFgrabber/vlfgrabber_dl0ao_test.htm

No signal in Warsaw? Strange. I assume it is rather the frequency
response of the antenna or local QRM (?) than propagation. But who knows.
The carrier was running until 8 UTC, as intended. The antenna current
dropped to 280 mA at times. I will work on that today...
