1. VLF: A single turn RX loop for VLF (score: 1): Author: DK7FC <[email protected]>; Date: Wed, 27 Apr 2016 18:31:20 +0200; Hi VLF, Today i've installed a second loop into the tree. It is a simple copper tube having 10 mm diameter and about 4m length. https://dl.dropboxusercontent.com/u/19882028/VLF/20160427_084708.jpg Th; /rsgb_lf_group-archives/html/rsgb_lf_group/2016-04/msg00338.html (14,632 bytes)

Re: VLF: A single turn RX loop for VLF (score: 1): Author: Paul Nicholson <[email protected]>; Date: Wed, 27 Apr 2016 17:52:39 +0000; You can eliminate the transformer by having more turns in the loop. But you'll probably find when you do the arithmetic, that it is cheaper to have fewer turns (or one turn) and a transformer.
