I think about 830km to Frankfurt. Perhaps Stefan can give the lat/long of the tx site? The rx here is at 53.703N 2.072W. Looks like Stefan has finished sending now. The noise level here is coming up
Dear Paul, Wolf, talked to Stefan on the cellphone about an hour ago. You can imagine he was overjoyed, I was actually worried he'd jump right up and fly off with his kite! He mentioned he had been a

Here is an interesting peak on the spectrum, http://abelian.org/vlf/tmp/ss100315a.png Frequency is 8970.0098 Hz +/- 2.5mHz. Bearing of this signal was 117/297 deg. Frankfurt is on 114. I've added a s

All it is simple a MIRACLE! I congratulate Stefan and all enthusiasts! I too tried to receive, but is ineffectual. It is necessary to improve RX.. 73 Andrey I think about 830km to Frankfurt. Wow! Per

Stefan, congratulations, this is excellent! The distance between us should be a bit over 180 km. I'm amazed at the strength of your signal. 73, Markus (DF6NM) --Ursprüngliche Mitteilung-- Von: Roger
Thank you for your report Paul. It reads very scientific if compared to my report, hi ;-) I'll keep rather writing as a fascinated dreamer who wants to share the euphoria with the others. But you do
Here is my reception report... Transmitter: Amateur radio station DK7FC transmitting from 49.77647N 8.699525E, (near Frankfurt) on 8970 Hz, ERP estimated at up to 1.7mW, vertically polarised CW. Rece

A very good summary and analysis Paul - thank you. Further tests, with an ID, will be good, but the signal clearly got there and 858.7kms is a very long way for an amateur signal on 8.97kHz. Who's ne
The signal was strongest up to 15:00, very narrow bandwidth too. Then there was a gap until about 15:20 or so, when the signal came back weaker and with some spread until just after 16:00. It is impo
Perhaps there will be some resonating problems but i do not expect them. I try to measure the antenna current and/or the voltage. The TX starting time is not exactly sure but perhaps arround 14 UTC.
Dear Stefan, Paul, Markus, LF Group, Congratulations on an excellent achievement! I actually left my RX running this afternoon, but there is no identifiable signal in the spectrograms, unfortunately.
No doubt Mal could put up a very large vertical and put some serious power into the feedline. That is only a 108,300 foot quarterwave inverted L...hi hi Is it possible to cross the pond on the 33km b
