Re: VLF: carrier at 8270.003

[Riccardo Zoli <riccardozoli80@gmail.com>]

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

Hello Riccardo!
I saw your signal in JN88KS again. Well done, thanks for your activity!
