Hi Frank,

Okay.  Now, to be ensure you did this as I intended, when you say

I hope you didn't use the "null adjust" control to do that.  You were  
actually "calibrating" your directional system and should have "driven  
to a null" using the "calib direction" control.

Right?  Is that what you did?

FB on the nulling ability.   Yes, I've heard from W6MDX who is pleased  
with the new GUI and performance so far.

73,  Joe K5SO
