Andrew,
Conjugate matching may be a very interesting subject and is indeed a much discussed topic on these walls. However, amongst the amateur fraternity, a "conjugate match" should be classified as being off topic. It does not exist. Not even when the tuner has been adjusted exactly for a VSWR equal to 1 to 1. Why? Because the internal impedance of the transmitter is not 50 ohms. It is not relevant. What is the internal impedance of YOUR transmitter? You will not find it mentioned in the manufacturer's operating or maintenance handbooks. In all likelihood you will not know what it is even if you designed and built the transmitter yourself! --- Reg, G4FGQ |

Old Son, Lord Kelvinator would be saddened by such a dismissal of actually delving into "knowing" by your meagre understanding that fails to offer an actual value that it IS. Such superstition that dominates this paucity would lead us to believe the Z is as slight as an angel wafting past in a dream (would that be in English Units, or metric?). Definitions by negatives is an amusing troll however. I do enjoy participation in kind: Let's see, the Z of a transmitter is NOT a dead parrot, nor five farthings, nor 10 inches, nor a polka dot dress, nor the gross national income of Lithuania, nor the combined weight of all your dead white scientists. I'm sure I missed a few.... ;-) 73's Richard Clark, KB7QHC |
