The evidence to prove the reception of Stefan's VLF signal= s is very strong indeed. Take a look at the various postings and screensho= ts here and at the various grabbers and websites.

Hi John,

weIl I think I can claim reception of=A0my 90 uW ERP kite signal on= =20 6470 Hz by Paul Nicholson on November 13:

But on the other hand, it looks=A0like on December 4th, 4X1RF=A0saw= =20 at least a very faint trace of Stefan=A0on 6470 Hz as well.

Ah John,=20

Sorry, there is another bug: The QTH of the kite antenna is JN49IS36VH, near Darmstadt.
The Earth antenna is in=20 Heidelberg, JN49IK67

I have changed the entries in the list= =20 below.
