HI Bob:

You should not be using the tuner in the KX3.  I also have an  
AlexLoop, and I always switch off the tuner when using the AlexLoop.
True, you may be getting the SWR lower by using the tuner, but that  
does not mean that the loop is radiating any better.  Use the tuning  
control on the loop and get the SWR as low as possible... yeah,  
sometimes it's darn touchy.  But as long as the SWR is minimized, the  
loop will be radiating as well as possible.  Even if the SWR is 1.5 or  
so.

The point of using a loop is that it is a resonant circuit, and when  
you feed it with energy at it's resonance point, the loop will  
radiate.  Practice getting the SWR down on higher bands (it's usually  
easier and less fussy there).  Then move to lower bands and practice  
there.
And, remember... -anything- in the nearby field will affect the tuning  
of the loop.  Even you.
