181. [AMPS] Where to read Reflected Power (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Tue, 28 Sep 99 13:01:06 -0500; Say, John, did you have to yell (caps) in your entire post? Ok, that aside, for precision weak signal ham work in the VHF/UHF range, I'll agree that a 15 dB return loss isn't great. However, there ha; /archives//html/Amps/1999-09/msg00289.html (10,178 bytes)

186. [AMPS] Reading Reflected and True (?) Power (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Wed, 29 Sep 99 16:44:51 -0500; WOW! You are asking some tough questions here! First of all, indicated forward power is likely to be the SUM of the forward and reflected power. One way to check is to tune the amp into your antenna.; /archives//html/Amps/1999-09/msg00323.html (9,925 bytes)

While I don't doubt your experimental results, I would have thought that you would not see that variance in drive power.

189. [AMPS] Reading Reflected and True (?) Power (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Thu, 30 Sep 99 15:48:05 -0500; OK! Now it makes sense. Yeah, you gotta retune for different loads. There will be SOME variation because as others point out, the SWR meter is really designed to optimally work in a relatively 50 Ohm; /archives//html/Amps/1999-09/msg00348.html (10,224 bytes)

THe FET's will be over-driven before the mixer is. That's why you can turn the preamp-off and get a tremendous improvement in IP3 performance. Agreed. True again as well.
