1. [Amps] Phase and amplitude of 2 tube amplifiers (score: 1): Author: Conrad PA5Y <g0ruz@g0ruz.com>; Date: Thu, 13 Oct 2022 12:37:10 +0000; I am going to attempt to use 2 identical monoband tube amplifiers to generate CP but before I start I have a question. The 90 deg delay for CP comes from the array orthogonal physical boom separation; /archives//html/Amps/2022-10/msg00021.html (8,265 bytes)
2. Re: [Amps] Phase and amplitude of 2 tube amplifiers (score: 1): Author: "hzp_electronics@juno.com" <hzp_electronics@juno.com>; Date: Thu, 13 Oct 2022 16:58:25 GMT; Conrad, The 90 deg angle of the two dipole elements is necessary to excite the 2 orthogonal polarities. For the radiation to be circular, the signals in these dipoles must differ in phase by 90 deg.; /archives//html/Amps/2022-10/msg00022.html (8,503 bytes)

However, I should clarify that I have been running CP on 144MHz EME since 2015 and with good success. I fully understand the implications of this and that th; /archives//html/Amps/2022-10/msg00023.html (10,743 bytes)

Better clue us Americans as to what that is. Jim W7RY I presume that this has been done in broadcast applications and I would like to know, assuming everything is tuned correctly how clos; /archives//html/Amps/2022-10/msg00025.html (9,766 bytes)
