   I was wondering what techniques you would employ to make these 
measurements....  I know a couple, but perhaps there's some new way that 
would be superior to what I was thinking of.  Once I have the "real world" 
range of impedances I need to deal with - then I have a point of departure 
for the tuner/matching network.

   Hmmm....  that might be an interesting addition to the Feedpoint Tuner.



    Thanks!
