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 am writing a piece on VLF for the Cave Radio & Electronics Group Journal and would like to include distance records.  Can people please confirm that the following information is correct (or not)?

Above-ground antennas

Hz	ERP mW	From	To	km
8970	58	Darmstadt	Israel/Haifa	2873
6470	9	Darmstadt	Poland/Warshaw	904
5170	5	Darmstadt	Poland/Warshaw	904

The QTH of SQ5BPF is Washaw. The rest is correct.

Earth current antennas

Hz	TX power W	Electrode spacing m	From	To	km
8970	250	600	Heidelberg	Roschbach	49.6

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.

73, Stefan/DK7FC

Thank you.
