Dear group, It seems that there are interesting theoretical questions to answer. And we, the practical interested's, could do this by trying that. Anyway if it is over 10km or 200km... Maybe we'll ge
Hi Stefan, Thanks for the proposals, and the boost of activity. I have passed on a few notes to the yahoo VLF group, so if you have more details about the kite antenna experiments (or even a schedule

Here's a live spectrum for 8970 +/- 1Hz - resolution is 5mH. Amplitude calibration is only within a factor of two or so. http://abelian.org/vlf/nb.shtml Ich habe die Frage gestellt. -- Paul Nicholson
Hello Paul, LF, I plan to transmit on 8,9700 kHz. Maybe, if i am in phone contact during the test i make QSY of some Hz if the RXing station has a carrier/line on this QRG. Or would this be a problem
Excellent Paul! Tnx for motivation ;-) I know the LT1028 as the best audio op amp (available for noncommercial customers) for such applications and have also built a narrow band LF preamp with it. In
