Still some doubt after a plunge of 12 orders of magnitude: If Zo=50+j0.000000000001 Lower precision If's still yield the same logical contradiction to: then it's close enough! then the VSWR will still be very close to a 1:1 match. The significant "if" is in your capacity to demonstrate Even if Zo=50+j2, You antenna boys don't build too many power amplifiers, obviously. Well, looking at the group title, it does not reveal rec.*.amplifiers, does it? And you have no credentials to speak of, unless selling to naifs, like selling dope to school children, falls into the same proof of authority. Oh wait a minute, you're one of the ham radio guys, right? That certainly explains a lot! S. |

Yeah...I guess those funny little numbers and letters you have by your name might have something to do with it...hmmmmm.... That certainly explains a lot! Must've been a brutal education. Think of the learning grade to climb Ohm's law. 73's Richard Clark, KB7QHC Speaking of "grade", you write like you're in the 2nd or 3rd. S. |

"It had been correct, when they incorrectly revised it (the conjugate reference), now it has been corrected again." Hope they got it right this time. My dictionary says: "conjugate - Either of a pair of complex numbers that are mutually related in that their real parts are identical and the imaginary part of one is the negative of the imaginary part of the other. We find maximum power transfer requires equal resistances in source and load. Also reactance, if any, be tuned out of the circuit. This is a conjugate match, such that source and load are conjugates by the dictionary definition. Many texts go into detail. I like the story of conjugates given in "Transmission Lines, Antennas, and Wave Guides", If it were at hand, I would quote from it. Found it. See page 43. The authors are King, Mimno, and Wing.

I'm curious--how did it handle Slick's 1.040807999:1 swr, from his 50+j2 load impedance? Walt, W2DU |

I present evidence to the contrary and this is the best he can do. What a loser. I worked about 30 states on two-meters from the depths of AZ using that amp. The present amp has participated in working all continents (WAC) on two-meters. |

I think Garvin Yee ("Dr. Slick") has WALG (Worked All Los Gatos) and maybe even WAB (Worked All Berkeley). Does that count? Roy Lewallen, W7EL |
