Uwe,
Thank you for the great signals!
Hoping to capture them in Virginia or Arizona sometime soon.
Would 500W into a 300m antenna imply approximately 10mW < ERP < 50mW after coil losses, at 9kHz?
Does your antenna orientation and elevation angle vary? (my maximum integration time is dependent on phase rate of change which is dependent on the antenna angle, even if the antenna angle is constant)
I enjoyed seeing the strong signals earlier this week on DK7FC, PA1SDB and other grabbers, thanks!

Hi Stefan and Eddy,
thanks for the reports. the equipment here is the same as ever (500W output into 300m aerial wire).
Markus asked for some OPERA OP4H tests. We have to schedule that test.

Hi Uwe, Tom, VLF,
Best signal ever from Tom, capture attached. Is it due to the propagation or did it improve your signal?
What about some tests in OPDS32 or maybe JT9-30? Unfortunately there is permanent rain here so i have to wait some days longer.

Hi All
Yes, yesterday was quieter on 8.9KHz with less catastrophic noise pulses. This meant that although Uwe's signal was less strong than during other tests I was in the catchment area. The low signal level means there are breaks in the line here in both 424uH and 47uHz FFT but I was able to catch some nice periods when the signal in 47uHz was10dB above the noise peaks. I can categorically confirm reception.
Thanks Uwe and (Tom DL8CAT) for the signal.
