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 dif= ferent to the kite antenna QTH).

Thanks too.
