1. [AMPS] Amp Pi Network Behavior (score: 1): Author: n4zr@contesting.com (Pete Smith); Date: Fri, 15 Sep 2000 09:44:29 -0400; This is a real simple question, I suspect. When I operate my SB-220 into a dummy load on 40M, the loading capacitor is at approximately mid-scale. The dummy, a cantenna, measures about 1.04 SWR on my; /archives//html/Amps/2000-09/msg00762.html (7,888 bytes)
2. [AMPS] Amp Pi Network Behavior (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Fri, 15 Sep 2000 09:57:42 -0400; Hi Pete, It could be that the antenna's feedline presents some equivalent parallel capacitive reactive, or the resistance is higher than 50 ohms, or both of those cases at the amplifier. It also coul; /archives//html/Amps/2000-09/msg00764.html (8,163 bytes)
3. [AMPS] Amp Pi Network Behavior (score: 1): Author: ccc@space.mit.edu (Chuck Counselman); Date: Fri, 15 Sep 2000 14:11:32 -0400; It could be (as you suggest) inductive reactance seen looking into the feedline, but (at least in principle) it could also be a smaller resistive component of the impedance seen looking into the feed; /archives//html/Amps/2000-09/msg00781.html (8,318 bytes)
