I'll try to work something like that out this weekend. Jack. Hi Jack, This is where you could as easily use a 50 Ohm resistor and your noise generator. There would be less interfering signals to confuse the data. You could also throw a deliberate mismatch onto the end like a 200 Ohm resistor. What value is that? If you measured 1:1, it would indicate you have an extremely lossy line (which tends to smooth out mismatches and gives some antenna inventors that warm snuggly feeling that they have licked the experts). 73's Richard Clark, KB7QHC |
