From memory one control tells you R and the other is Xc or Xl depending
which way from zero. So set it for R then X and keep on till you get no
improvement.

I am working on a project to build a switchable impendence balun network
to
go between my 450 ohm twin lead and auto antenna tuner, using a Palomar rx
noise bridge.
I am somewhat confused interpretating the noise bridge readings, and the
Palomars book is a bit vague on interpretating the resistance vs the xl
and
xc readings.
I guess I should take the readings and plug them into a smith chart..but I
know even less how to interpolate that little beastie.
any help?
