Hi John,
weIl I think I can claim reception of my 90 uW ERP kite signal
on 6470 Hz by Paul Nicholson on November 13:
Transmitter near Nuernberg at 49.3874 N 11.1692 E, receiver
Todmorden 53.703N 2.072W, distance about 1034 km according to
But on the other hand, it looks like on December 4th, 4X1RF saw
at least a very faint trace of Stefan on 6470 Hz as well.
Best wishes,
MArkus

Ah John,
Sorry, there is another bug: The QTH of the kite antenna is JN49IS36VH,
near Darmstadt.
The Earth antenna is in Heidelberg, JN49IK67
I have changed the entries in the list below.

I did successful tests to Roschbach just on 8970 Hz, not on 6470 and
5170. The distance is 49.6 km (since my earth antenna QTH is different
to the kite antenna QTH).
Thanks too.
