Stan, Yes, check the DC Power thru the coax. If you see a significant voltage drop, the first thing to look for is a bad shield connection between the shield and connectors. Right now, you have too many variables in the 'equation' - follow the steps below to find out what is working and

Aaron, my SWR is being reported by the KX2 as below 1.2:1 at all times; usually 1:1. I'm using a window line fed doublet through an SGC-231 autocoupler.  This situation occurs on all HF bands.   I do not have either the KX2 internal ATU nor do I have the KXPA100 ATU.  Now you've got me
