[Elecraft] K3 as an antenna analyzer?

[Dave G4AON]

I have an LP100 that does that and an MFJ 259B... I think Wayne, Eric 
and Co have enough on their plate getting the basics working fully 
without being side tracked into "nice to have" extras that one or two 
users may use once or twice...

/I have an idea for a new feature, for Eric, Wayne and the others to think
about. Now that the K3 can read and display the LC settings for the
internal autotuner, wouldn't it be neat to be able to calculate the
corresponding antenna impedance at the given frequency (Z = R +jX)?/
