1. [Amps] Tapping a plate tank coil (score: 1): Author: Bill Turner <dezrat1242@ispwest.com>; Date: Fri, 06 Jan 2006 20:47:54 -0800; I know it is common and accepted practice to short out the turns on an air-core plate tank coil for bandswitching, but is it ok for powdered iron core toroids in that situation? My understanding is t; /archives//html/Amps/2006-01/msg00239.html (6,986 bytes)

The turns in a spaced turn air cored inductor are only loosely coupled, so shorting out turns just detours flux around those turns. Since flux is fringing all over the plac; /archives//html/Amps/2006-01/msg00240.html (9,030 bytes)

Re: [Amps] Tapping a plate tank coil (score: 1): Author: Bill Turner <dezrat1242@ispwest.com>; Date: Fri, 06 Jan 2006 22:02:20 -0800; I thought about having three separate toroids, one each for 160/80/40. That way the flux is not coupled between them and shorting across one or more would have no harmful effect at all. 73, Bill W6WR; /archives//html/Amps/2006-01/msg00241.html (7,474 bytes)
