Hallo Riccardo!
Hmm, it is interesting - I have never heard about that effect.
I saw your signal again, see the picture. I am pleased, you are active on VLF. My receiver is continuously "ON"  for your tests.

73!

Lubos,

many thanks for your report!
I'm testing the coil for long transmissions; I have observed, for my first time, that atmospheric conditions affects antenna current: for example, today it's been a sunny and dry morning, in fact I reach 625mA; in the afternoon the sky was so cloudy and I have measured only 570mA. Now the value is stabilized around 590mA (relative humidity's still high: 86%).
I'm preparing an EbNaut setup for next days: I will announce details soon.

All the best


73 de Riccardo IW4DXW
