tried some amateur rubbish the other year, but the problem with
amateur constructions is ususally that you cannot make two units which
performs similarly, and it is difficult to tell what decides the
impedance. If somebody have another opinion I'll be pleased to hear,
it is not 1% accuracy I am after, 10% is good enough and that the
readings are successively the same for the same conditions. Put some
info about some simple couplers you can make on my site, you'll find
it with google search for "Bird Model 43 patent description"
