Left it on overnight.

Would you like it on 24/7, I see diurnal variations similar to Marcus but more pronounced due to my lower signal strength.

Hi Stefan

I didn't quite believe what I was reading you may like to take a look at my Grabber.

Hello Markus,

thanks for the feedback. Wonderful, now it is 30 dB in 424 uHz. DL0AO could run a 3.8 mHz '600' RDF spectrogram and a phase and signal level plot, so we could see propagation effects much better.
You could already see QRSS-60 from me! I will try that soon.
The carrier is still on the air. It will run the whole day and night...

Hi VLF,

Since 23 UTC a 700 mA carrier is running on 17.4701 kHz!

It is a little surprise to the VLF community i think ;-)

Legal? Yes: http://www.iup.uni-heidelberg.de/schaefer_vlf/VLF/17,47kHz_Sonderlizenz.jpg
Actually the document has 3 pages but the other ones are no so relevant.
My ERP is limited to 5 mW. I did not request more because more isn't possible anyway with this antenna.

I wound a big single layer coil with 0.5 mm enameled wire on a PVC tube with 315 mm outher diameter.

0.7 A is just a first careful step. The coil is designed to hold 1.5 A 'key down'.

The carrier will run the whole night and even tomorrow at daytime.

Worldwide reports are welcome ;-)

It is not sub-9-kHz but still VLF, the 17 km band!! So give it chance :-)

The tree has still some solar power to stream the signal from the EW loop down to the city, so there is a feedback spectrogram at

73, Stefan

PS: I still can hear that tone of the coil. It is terrible! Be happy when you are older than me!
