But Markus
How does anyone know that the faint trace was
Stefan without an ID. I wish everyone success but there is so much guesswork
about. I need to be convinced and no way would I claim any hits without a
proper callsign ID on a frequency.
I saw a trace appear once and it was
suggested by a VE7 station that it was my neighbours toaster, but by
conincidence iit came on and off roughly at the same time as the DK carrier
transmission.

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, JN49IK67I have changed the entries in the list
below. 73, Stefan Am 15.12.2010 12:04, schrieb Stefan Schäfer:

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.
