Re: VLF: 8270.003 Hz

Hi Riccardo, Tom,

yes indeed a very nice signal! And I'm glad to see the first green trace in DL0AO's 424 uHz colour spectrogram. Scroll about half way down the page:
https://vlf.u01.de/

You are also visible on my suburban grabber at home, which is several dB more noisy - anyway a good peak in 21 uHz and a very feeble trace in 424 uHz:

Superb in Todmorden, as always:

Let's hope for some sunshine in Heidelberg so that Stefan's tree will come back online soon:

Hi Riccardo,

after night noise having decreased there are visible traces of your
signal on the DL0AO-VLF-Grabber, JN59VK:  vlf.u01.de

At 424 uHz on the N-S-earthloop and even better on the vertical omni
ant; looking to the spectogram at 20,93 uHz a stronger trace is coming
up - perhaps you can stay on the QRG a day longer ;-)

73 es gl,
Tom, DK1IS
