I wouldn't have mentioned it Jim, except Tony's funny comment muddied the water some. I like humor, but I also don't want anyone to be confused by humorous dialog. I am sure Tony knows how the analyzer works. In your case, there were enough confusing factors to leave some doubt about the polarity that was not resolved without a lot of thought and experimentation. It usually is not that difficult to reason the polarity of the reactance. Willis 'Cookie' Cooke K5EWJ & Trustee N5BPS, USS Cavalla, USS Stewart

I should have said that it simply shows numbers and it is up to the user to figure out the correct polarity. Thanks for the input. > I think the original statement was incorrect.
