Hi Stefan,

Dimitris, what about your recent VLF experiments? Any progress?
>

 I have built a simple xtal based oscillator for 8.7 kHz which is coupled
to a small audio amp (~10W). I am planning to use that to do some tests
with the earth dipole to get some real data. If that works, I will probably
build a simple RF generator capable of more power.

With the success I am having currently with the earth dipole at 136 kHz
(250 m earth dipole, 2 W RF, QRSS30, solid copy received by VK2XV at 217
km), I will focus on the earth dipole first before I start thinking of
anything else. I will let the group know if there are any developments in
that front.

In the meantime, here is some food for thought:
