1. [TenTec] Pegasus Erratic SWR readings (score: 1): Author: "Dave White" <dwds@trinustech.com>; Date: Fri, 13 Feb 2004 13:59:30 -0700; Has anyone noticed erratic SWR readings using SSB from the Pegasus when the SWR gets about 1.5 to 1 or higher? Here's the situation: SWR less than 1.5 to 1: absolutely no problems at anytime. SWR abo; /archives//html/TenTec/2004-02/msg00412.html (7,723 bytes)
2. Re: [TenTec] Pegasus Erratic SWR readings (score: 1): Author: "Mark Erbaugh" <mark@microenh.com>; Date: Fri, 13 Feb 2004 16:24:34 -0500; Dave, I think what you are seeing is "normal." It is caused by the way SWR is calculated in the software. Basically, the Pegasus reports values representing forward power and reflected power readings; /archives//html/TenTec/2004-02/msg00414.html (9,635 bytes)
3. [TenTec] Pegasus Erratic SWR readings (score: 1): Author: "Guy Zebrick" <gwzmcz@earthlink.net>; Date: Fri, 13 Feb 2004 21:08:19 -0600; Interesting - I also am seeing intermittent high SWR. This has caused my latest version of Carl's software to automatically drop to the lower power levels. I thought that I had trouble with my coax o; /archives//html/TenTec/2004-02/msg00430.html (7,402 bytes)

Re: [TenTec] Pegasus Erratic SWR readings (score: 1): Author: "Carl Moreschi" <n4py@earthlink.net>; Date: Sat, 14 Feb 2004 03:58:53 -0000; The idea of the power reduction feature is to reduce power BEFORE the finals blow. Adding a delay here defeats the purpose of the feature. I don't see the erratic SWR with my pegasus. 73, Carl Moresc; /archives//html/TenTec/2004-02/msg00432.html (8,253 bytes)

Re: [TenTec] Pegasus Erratic SWR readings (score: 1): Author: "Carl Moreschi" <n4py@earthlink.net>; Date: Sat, 14 Feb 2004 13:29:04 -0000; I re-read Mark's post on this subject and did some more SSB experiments, this time with my speech processor turned off. I did indeed now see an erratic SWR on my pegasus. I believe Mark's analysis is; /archives//html/TenTec/2004-02/msg00435.html (9,747 bytes)

Re: [TenTec] Pegasus Erratic SWR readings (score: 1): Author: "Dave White" <dwds@trinustech.com>; Date: Sat, 14 Feb 2004 10:13:06 -0700; Hi Carl: Thanks for reconsidering the cause and effect of the erratic SWR readings. Might I suggest some sort of short term averaging algorithm to help with the problem? Perhaps SWR or reflected powe; /archives//html/TenTec/2004-02/msg00441.html (8,215 bytes)

Re: [TenTec] Pegasus Erratic SWR readings (score: 1): Author: "Mark Erbaugh" <mark@microenh.com>; Date: Sat, 14 Feb 2004 12:19:14 -0500; Carl, finals see Most non-TT rigs are designed with hardware that will drop (fold back) the power output when a high SWR is sensed. However, TT has always claimed that their finals can handle high SW; /archives//html/TenTec/2004-02/msg00442.html (8,672 bytes)

Re: [TenTec] Pegasus Erratic SWR readings (score: 1): Author: "Carl Moreschi" <n4py@earthlink.net>; Date: Sat, 14 Feb 2004 21:12:57 -0000; The Pegasus does not have over current protection and as such has a small exposure to an overcurrent situation blowing the finals. And this overcurrent situation would most likely occur with a high S; /archives//html/TenTec/2004-02/msg00444.html (10,536 bytes)

Thanks for the kind words. Do you think the AirPax magnetic breakers provide sufficient over current protection?
