Stefan,
this is great news! I've reconnected my VLF preamp in series to the 74 kHz tap on
the antenna, and reactivated the VLF grabber:
I'm also trying to export data from
the 478 µHz spectrogram to Opds, searching for possible Op-32
signals near 8.97 kHz:
Good luck!

Hi all,
Tomorrow the rain probability is just 10% and so i
think i can risk to
run a short VLF experiment on 8970.00500 Hz. I'm using
the fixed antenna
at JN49IK00WD. These days, the QRN is very low for quite a
long time!
The plan is to run about 500W RF power, or more, depending on the
voltage limit of the antenna. And the plan is to start transmitting
tonite, after the experiment with VO1NA, i.e. i'll come on air arround 2
UTC, hopefully. I will run the test until the late afternoon. First i'm
TXing a stable frequency until 9 UTC, later some DFCW-600, and then
maybe some tests in OPDS32.
Suggestions welcome.
BUT it all depends on
the WX. If it starts to rain then i have to stop.
Will someone give it a try
and watch for me?
73, Stefan/DK7FC
