Dear Stefan, LF,
 
this afternoon Aug 29, my 0.2 mW kite transmission from Nuernberg was copied by the DK7FC grabber. The signal was on air between 11:45 and 14:30, with a few interruptions. At my local grabber 5 km away, best SNR was 28 dB in 0.36 Hz and about 53 dB in 0.95 mHz FFT resolution. The detailed timing was
 
 UT  Aug. 29    f/Hz
11:45 - 11:55  8969.98
11:55 - 12:03  8969.97
12:08 - 13:01  8969.98
13:05 - 13:20  8969.98
13:20 - 14:30  8969.97
 
The location was 49.3875 N 11.1688 E. There are a lot of new buildings in the area, which are not shown on Google aerial imagery.
 
Attached below are my notes intended for the LF reflector from this afternoon. Though I could read and write mails from the mobile internet connections, they were mysteriously not forwarded by the RSGB reflector.
 
This was a very enjoyable afternoon! Thanks a lot Stefan, for all the work you put into setting up and operating your VLF grabber.

Dear LF,

I'm currently outdoors with a kite, transmitting a carrier on 8969.98 Hz (GPS controlled), about 0.2 mW EMRP. It seems to be visible on the Heidelberg grabber now.
