1. AW: LF: VLF TX coil ready (score: 1): Author: Stefan Schäfer <[email protected]>; Date: Mon, 8 Mar 2010 20:27:09 +0100; Paul, LF, Tnx for the calculations. Today i again added some turn to the coil. Now it has L = 550mH, just optimal. My antenna has C=580pF (measured on 137kHz). When theoretically calculating the C of; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-03/msg00040.html (14,958 bytes)

4. Re: AW: LF: VLF TX coil ready (score: 1): Author: Paul Nicholson <[email protected]>; Date: Mon, 08 Mar 2010 21:56:04 +0000; Oh, rather a cone shaped coil. That will alter my overtone calculations. They are important if you are driving the coil with a switching waveform, as the system will happily ring on each edge and ra; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-03/msg00604.html (13,280 bytes)
