Hi Uwe,

I was doing some tests with my PA some time ago. Now all EMC problems are solved, it works without problems at 320V DC. It looks like this test has caused some overloading of the grabber since i was testing at 8970 Hz. No antenna was connected and it was indoors and in 30m distance. Strange...
Now i'm doing a first test with the PA, VOX and OPDS32 on my own grabber to see if i can make a decode. Should be finished arround 23:45 UTC and displayed at http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html , like your decode, if it happens. I've reduced the signal, 1 kOhm in series to a LOPT transformer and 5m wire in 1m above ground in 30m distance. Voltage across the h bridge is 3V :-) The signal is 15 dB in my 600 window so your signal should not be affected.

Good luck!

73, Stefan/DK7FC
