1. AW: LF: VLF TX experiments_short report (score: 1): Author: Stefan Schäfer <[email protected]>; Date: Tue, 2 Mar 2010 21:09:03 +0100; Hi Alexander, LF, Yes, i assumed the Q of the coil to be very high due to the big wire that is used in it. But thus the internal C is high, so stray currents occur that increase the resistive losses.; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-03/msg00004.html (14,277 bytes)
2. Re: AW: LF: VLF TX experiments_short report (score: 1): Author: Roger Lapthorn <[email protected]>; Date: Wed, 3 Mar 2010 20:00:20 +0000; Thank you Stefan. Good luck with the VLF experiments in the days ahead and I hope that Marcus and others manage to receive you signals. 73s Roger G3XBM -- http://g3xbm-qrp.blogspot.com/ http://www.g3; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-03/msg00365.html (11,764 bytes)

Remember, this is well out of near reactive zone. Thus field decreases as 1/D and if you increase voltage to 20 kV then distance will be 20:1.; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-03/msg00396.html (13,185 bytes)
