I'm sure it's a calculation. I believe it was you who pointed out that
once you know the Z, you can calculate the SWR for any Z0. And you don't
need to know the sign of the reactance in order to do it. So that's
surely the way it's done.

Can't imagine that yours does the calculation different than mine. . .
hm, maybe it does. . .mine says "Ver. 1.24" when it starts up. What does
yours say?

Thanks Roy. Mine shows it to measure 75 normally, but 1.3:1 in the Advanced
3 @75 ohms. Either I better change my brand of smokes or the Micro forgot
how to do the calculation... Better go back and try again to see it I
goofed somewhere...but I've done that several times...... . . . . .

Am I correct about this being simply a calculation?
