5. [TowerTalk] Coil Loss (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Wed, 2 Jun 2004 21:37:25 -0400; a Q of 10 (which you'll dissipate spread out over 20-30 square inches) You may want to reconsider that Jim. Talking about component Q, the loss might be a fraction of a percent or extremely high wit; /archives//html/Towertalk/2004-06/msg00040.html (9,068 bytes)

Re: [TowerTalk] Coil loss (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Wed, 2 Jun 2004 21:43:53 -0400; The problem is always cost, but adding one additional short can make a whale of a difference! The easiest trick is to not operate near frequencies when the coil has an internal resonance in the unuse; /archives//html/Towertalk/2004-06/msg00041.html (8,903 bytes)
