1. [Amps] Tune cap at minimum (score: 1): Author: "Dave Hachadorian" <k6ll.dave@gmail.com>; Date: Thu, 3 Oct 2013 10:17:33 -0700; I have an amplifier that tunes up on 21 MHz with the tune capacitor at minimum value. It acts like the capacitance should be even lower for max efficiency and output on 21 MHz. All of the other bands; /archives//html/Amps/2013-10/msg00013.html (7,555 bytes)
2. Re: [Amps] Tune cap at minimum (score: 1): Author: Glen Zook <gzook@yahoo.com>; Date: Fri, 4 Oct 2013 17:40:31 -0700 (PDT); To lower the inductance, the turns need to be farther apart. However, that will affect the other bands as well. It would be better to move the 15-meter tap so that less turns are selected. I would; /archives//html/Amps/2013-10/msg00026.html (8,271 bytes)
3. Re: [Amps] Tune cap at minimum (score: 1): Author: "Carl" <km1h@jeremy.mv.com>; Date: Fri, 4 Oct 2013 20:54:37 -0400; Manipulating the 15M coil should have little effect on 20M and none that will be noticable on the other bands. In all cases the full tuning ranges should be fine. If it is way off then moving a tap i; /archives//html/Amps/2013-10/msg00027.html (9,125 bytes)
