1. [Amps] SWR & OPEN WIRE (score: 1): Author: "Mr. and Mrs. Magoo" <magoo@isp.ca>; Date: Thu, 23 Apr 2009 19:25:43 -0400; Shortly after I was licensed in 1959 I built an 813 rig from the Handbook. My antenna was a 65 ft flat top fed with 450 ohm open wire. I had a very crude antenna coupler and my "output indicator" was; /archives//html/Amps/2009-04/msg00300.html (7,211 bytes)
2. Re: [Amps] SWR & OPEN WIRE (score: 1): Author: Alek Petkovic <vk6apk@bigpond.com>; Date: Fri, 24 Apr 2009 10:10:13 +0800; snip Yeah, that's dead right. You match the source impedance (amplifier output) to the load impedance (coax, tuner or whatever) and maximum power transfer takes place. That's all you need to worry ab; /archives//html/Amps/2009-04/msg00301.html (7,402 bytes)

You gain a new appreciation for keeping the SWR LOW.<:-)) 3:1? How about finding the amp kicks out at 1.3:1, or rolls back the output by 300 or 400 watts.

4. Re: [Amps] SWR & OPEN WIRE (score: 1): Author: "Carl" <km1h@jeremy.mv.com>; Date: Fri, 24 Apr 2009 08:34:45 -0400; That is so absolutely simple but many seem to not grasp it. Its almost like modifying an amp to do do the most efficient transfer is some sort of sacrilige. An analogy would be a race car. The engine; /archives//html/Amps/2009-04/msg00309.html (8,601 bytes)
