3. Re: [RFI] Telephones and DSL (score: 1): Author: N1BUG <paul@n1bug.com>; Date: Sun, 09 Dec 2012 19:42:35 -0500; Question about DSL. Can too much ferrite kill the DSL signal or mess up the SNR? Is the DSL signal affected by say a 160 tuned circuit/trap or is it a DC thing and not RF? I'm looking to cure 1 KW mo; /archives//html/RFI/2012-12/msg00026.html (7,684 bytes)

W2RU went through DSL issues, including 160M, in a serious way a couple of years ago, reached good solutions, learned a lot, and published it, I think on a website.
