Hi John,
=C2=A0
weIl I think I can claim reception of=C2=A0my 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=C2=A0about 1034 km according to
=C2=A0
But on the other hand, it looks=C2=A0like on December 4th, 4X1RF=C2= =A0saw at least a very faint trace of Stefan=C2=A0on 6470 Hz as well.
=C2=A0
Best wishes,
