Sorry Tom, I should have been more precise in my post. I meant to say that 
those were indeed DC measurements only. I went on to explain that RF based 
measurements are a problem because of the high levels of AM BC at my QTH.

Measuring the surge impedance and adjusting the termination resistor value 
to achieve minimum change in impedance when swept, gives resistor values 
that are very close to the impedance measured. Of course, with all that BC 
RF flying around, I can't be sure the measurements are correct.

Now, if you have a suggestion that might provide a better answer, I'd sure 
like to hear it.
